Fill a textbox with data from database - c#

I have a couple of textboxes on my page and want to fill them with data from the database. I do the query and get (in my case) a Film object back wich i use to fill textboxes but it won't work.
Here is my code:
private void FilmInfo(int gekozenFilm)
{
BLFilm blFilm = new BLFilm();
Film film = blFilm.GetFilmById(gekozenFilm);
TextBoxFilm.Text = film.Naam;
TextBoxRelease.Text = film.Releasedatum.ToString();
TextBoxTrailer.Text = film.Filmpje;
TextBoxAfbeelding.Text = film.Afbeelding;
}
There is a Film object in film but for some reason the textboxes don't display the text.
Code (that is relevant) for the entire page:
protected void ListBoxMovies_SelectedIndexChanged(object sender, EventArgs e)
{
int gekozenFilm;
gekozenFilm = Convert.ToInt32(ListBoxMovies.SelectedItem.Value);
FilmInfo(gekozenFilm);
}
private void FilmInfo(int gekozenFilm)
{
BLFilm blFilm = new BLFilm();
Film film = blFilm.GetFilmById(gekozenFilm);
TextBoxFilm.Text = film.Naam;
TextBoxRelease.Text = film.Releasedatum.ToString();
TextBoxTrailer.Text = film.Filmpje;
TextBoxAfbeelding.Text = film.Afbeelding;
}
The .aspx page
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<section id="context">
<article id="left">
<h2>Movie CRUD</h2>
<div class="seperator">
<!-- seperator -->
<asp:Label ID="LabelNaam" runat="server" Text="Naam"></asp:Label>
<asp:TextBox ID="TextBoxFilm" runat="server" Width="250px"></asp:TextBox>
<br />
<asp:Label ID="LabelRelease" runat="server" Text="Releasedatum"></asp:Label>
<asp:TextBox ID="TextBoxRelease" runat="server" Width="185px"></asp:TextBox>
<br />
<asp:Label ID="LabelTrailer" runat="server" Text="Trailer"></asp:Label>
<asp:TextBox ID="TextBoxTrailer" runat="server" Width="241px"></asp:TextBox>
<br />
<asp:Label ID="Label1" runat="server" Text="Afbeelding"></asp:Label>
<asp:TextBox ID="TextBoxAfbeelding" runat="server" Width="209px"></asp:TextBox>
</div>
</article>
<article id="right">
<h2>Movies</h2>
<asp:ListBox ID="ListBoxMovies" runat="server" Height="141px" Width="315px" OnSelectedIndexChanged="ListBoxMovies_SelectedIndexChanged" ViewStateMode="Inherit" AutoPostBack="True"></asp:ListBox>
</article>
</section>
</form>
I've tried putting breakpoint pretty much everywhere and textboxes have a value for text but on the page it remains empty?

It'll be a good idea to check if your updatetemplate contains the Textboxes you want to fill.

Why don't you use a Recordset?
It is very easy to use and I think is good for your situation:

How can I add selected value in an asp.net ajax toolbox autocomplete to a label?

I have got the Ajax toolkit autocomplete working using the following asp.net and C# code.
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<div>
Search our Languages: <asp:TextBox ID="txtLanguage" runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server"
TargetControlID="txtLanguage" MinimumPrefixLength="1"
ServiceMethod="GetCompletionList" UseContextKey="True">
</asp:AutoCompleteExtender>
<br />
<br />
<asp:Button ID="btnAddSelected" runat="server" Text="Add to chosen Languages >"
onclick="btnAddSelected_Click" />
<br />
<br />
<asp:Label ID="lblSelectedLanguages" runat="server" Text=""></asp:Label>
</div>
</form>
This is my codebehind C#:
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey)
{
// Create array of languages.
string[] languages = { "Afrikaans", "Albanian", "Amharic", "Arabic", "Azerbaijani", "Basque", "Belarusian", "Bengali", "Bosnian", "Bulgarian" };
// Return matching languages.
return (from l in languages where l.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase) select l).Take(count).ToArray();
}
protected void btnAddSelected_Click(object sender, EventArgs e)
{
lblSelectedLanguages.Text += txtLanguage.Text += ", ";
}
The selected language is added to the label when the button is clicked, however I would like to remove the button and make the selected item from the autocomplete added to the label automatically, using the partial postback from the Ajax toolkit.
Can someone please advise as to how I can achieve this?
Thanks.
Handle OnClientItemSelected on the AutoCompleteExtender control to run a javascript function
All the javascript does is simply fire off the TextChanged event when the selection is made (works on both Enter and left click)
ASPX:
<head runat="server">
<title></title>
<script type="text/javascript">
function ItemSelected(sender, args) {
__doPostBack(sender.get_element().name, "");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
Search our Languages:
<asp:TextBox ID="txtLanguage" autocomplete="off" runat="server" OnTextChanged="TextChanged" />
<asp:AutoCompleteExtender OnClientItemSelected="ItemSelected" ID="AutoCompleteExtender1"
runat="server" TargetControlID="txtLanguage" MinimumPrefixLength="1" ServiceMethod="GetCompletionList"
UseContextKey="True">
</asp:AutoCompleteExtender>
<br />
<asp:Label ID="lblSelectedLanguages" runat="server"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</form>
</body>
Code behind:
protected void TextChanged(object sender, EventArgs e)
{
lblSelectedLanguages.Text += txtLanguage.Text += ", ";
}
It looks like you just need to hook onto the on text changed event of your text box and then put your logic in code benind.Something like this
Markup
<asp:TextBox ID="txtLanguage" OnTextChanged="txtLanguage_textChanged" AutoPostback="true" />
Then in your code behind
protected void txtLanguage_textChanged(object sender, EventArgs e)
{
//use the retrieved text the way you like
lblSelectedLanguages.Text =txtLanguage.Text;
}
Hope this helps.I would also suggest that you try looking into the JQuery autocomplete widget.It has brought me sheer happiness and I surely did divorce the autocomplete extender.

How to handle CreateUserWizard Steps in Asp.Net?

I have used asp.net creatuserwizard in my project. And my custom template looks like this
<WizardSteps>
<asp:CreateUserWizardStep ID="CreateUserWizardStep0" runat="server">
<ContentTemplate>
//my custom code is here
</ContentTemplate>
<CustomNavigationTemplate>
</CustomNavigationTemplate>
</asp:CreateUserWizardStep>
Now, in Step2 i have code like this;
<asp:WizardStep ID="CreateUserWizardStep1" runat="server" AllowReturn="False" StepType="Step">
<div class="accountInfo">
<fieldset class="register">
<p>
<asp:Label ID="CityLabel" runat="server" AssociatedControlID="City">City:</asp:Label>
<asp:TextBox ID="City" runat="server" CssClass="textEntry"></asp:TextBox>
</p>
<p>
<asp:Label ID="CountryLabel" runat="server" AssociatedControlID="Country">Country:</asp:Label>
<asp:TextBox ID="Country" runat="server" CssClass="textEntry"></asp:TextBox>
</p>
</fieldset>
</div>
</asp:WizardStep>
So, my question is, how do i insert 'City' textbox value in my user profile as i click on next in step2.
You can handle the NextButtonClick of the Create User Wizard and check for the currentstepindex:
protected void YourCreateUserWizard_NextButtonClick(object sender, WizardNavigationEventArgs e)
{
if (e.CurrentStepIndex == YourStepIndex)
{
...
}
}
You will need to add code to handle the CreatedUser event of the wizard control.
This part should be in the code behind, there you have access to the current state of the wizard:
protected void CreateUserWizard_CreatedUser(object sender, EventArgs e)
{
// Finde the value
var cityField = (TextBox)CreateUserWizard.CreateUserWizardStep1.FindControl("City");
// use the field value todo whatever you want
}

UpdatePanel, ModalPopupExtender, and enter keypress issues

Have an UpdatePanel that contains 2 panels with default buttons set to listen to enter key presses. That UpdatePanel is the PopupControl for a ModalPopupExtender.
Running into an issue when pressing enter in the modal popup in which the entire page posts back. Any ideas? Here are some code snippets (I've removed the extraneous fields...):
<div runat="server" id="divShippingEstimatorPopup" class="shippingEstimatorModalPopup">
<asp:UpdatePanel ID="upPopup" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="pnlShippingEstimator" DefaultButton="lnkbtnGetEstimates">
<div class="title content_title">Shipping Estimator</div>
<asp:Label runat="server" ID="lblMessage" />
<table cellpadding="0" cellpadding="0" class="shipping">
<!-- Removed to shorten code snippet -->
<tr>
<td colspan="2">
<div class="buttonHolder">
<Monarch:LinkButtonDefault runat="server" ID="lnkbtnGetEstimates" CssClass="button_action button_margin_right" CausesValidation="false">Get Estimates</Monarch:LinkButtonDefault>
<asp:LinkButton runat="server" ID="lnkbtnCancel" CssClass="button_secondary button_secondary_fixed" CausesValidation="false">Cancel</asp:LinkButton>
<div class="clear"></div>
</div>
<div class="clear"></div>
</td>
</tr>
</table>
</asp:Panel>
<asp:Panel runat="server" ID="pnlShippingOptions" DefaultButton="lnkbtnSetEstimate">
<div class="shippingOptionsHolder" runat="server" id="divShippingOptionsHolder">
<!-- Removed to shorten code snippet -->
<div class="buttonHolder">
<Monarch:LinkButtonDefault runat="server" ID="lnkbtnSetEstimate" CssClass="button_action">Set Estimate</Monarch:LinkButtonDefault>
<div class="clear"></div>
</div>
<div class="clear"></div>
</div>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
Keep in mind the LinkButtonDefault is just this:
public class LinkButtonDefault : LinkButton
{
private const string AddClickScript = "SparkPlugs.FixLinkButton('{0}');";
protected override void OnLoad(EventArgs e)
{
string script = String.Format(AddClickScript, ClientID);
Page.ClientScript.RegisterStartupScript(GetType(), "click_" + ClientID,
script, true);
base.OnLoad(e);
}
}
Finally, here is the rest of the control:
<asp:UpdatePanel runat="server" ID="upGetEstimate">
<ContentTemplate>
<asp:LinkButton runat="server" ID="lnkbtnGetEstimate" CausesValidation="false">Get Estimate</asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
<ajaxToolKit:ModalPopupExtender ID="shippingEstimatorPopupExtender" runat="server" TargetControlID="lnkbtnFake" PopupControlID="divShippingEstimatorPopup" BackgroundCssClass="monarchModalBackground"></ajaxToolKit:ModalPopupExtender>
<asp:LinkButton runat="server" ID="lnkbtnFake" style="display:none;"/>
<Monarch:PopupProgress ID="popupProgressGetEstimate" runat="server" AssociatedUpdatePanelId="upGetEstimate" />
<Monarch:PopupProgress ID="popupProgressGetEstimates" runat="server" AssociatedUpdatePanelId="upPopup" />
Basically, the user clicks Get Estimate, a progress bar appears while it loads the form, the form shows in a modal popup. I'm guessing this is something simple, but I can't just get the right combination to get this working properly.
First of all try what happens if you use your scriptmanager to register script in the code behind.
I use this method for registering scripts:
public static void RegisterStartupScript(Control c, string script)
{
if ((ToolkitScriptManager.GetCurrent(c.Page) as ToolkitScriptManager).IsInAsyncPostBack)
ToolkitScriptManager.RegisterStartupScript(c, c.GetType(), "Script_" + c.ClientID.ToString(), script, true);
else
c.Page.ClientScript.RegisterStartupScript(c.GetType(), c.ClientID, script, true);
}
This checks if you have ScriptManager in your page. If it doesn't, it uses the full postback version.

Error Help::Multiple controls with the same ID 'ctl00' were found. FindControl requires that controls have unique IDs

Getting the above Error.
I want the IDs of the Accordian to be unique everytime it is bound. I added Accordian pane dynamically in my code..Its not working:-
like this :-
for(int i=0;i< dt.Rows.Count;i++)
{
AccordionPane accp = new AccordionPane();
accp.ID = "accp" + i.ToString();
Accordion1.Panes.Add(accp);
Accordion1.DataSource = dt.DefaultView;
Accordion1.DataBind();
}
I want the IDs of the Accordian to be unique. How can I accomplish what I want ?
Aspx Page:-
<div id="div1" runat="server">
<telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1" OnTabClick="RadTabStrip1_OnTabClick" ClickSelectedTab="true">
</telerik:RadTabStrip>
<br /><br />
<telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0">
</telerik:RadMultiPage>
</div>
<cc1:Accordion ID="Accordion1" runat="server" FadeTransitions="true" Visible="true" AutoSize="None"
SelectedIndex="0" RequireOpenedPane="false" TransitionDuration="250" HeaderCssClass="accordionHeader" ContentCssClass="accordionContent" CssClass="toggler">
<HeaderTemplate>
<b style="color: Black">
<%#Eval("Ques")%>
</b>
</HeaderTemplate>
<ContentTemplate>
<p> <%#DataBinder.Eval(Container.DataItem, "QuesAns")%></p>
</ContentTemplate>
</cc1:Accordion>
<br />
You shouldn't be calling BindAccordion multiple times because (I'm guessing) that's why you're ending up with multiple controls with the same ID.
You're calling it in both Page_Load and RadTabStrip1_OnTabClick. My best guess from your code is that you should only call it once from Page_Load when !IsPostBack like you have already.
If that doesn't work, try the following:
protected void BindTabStrip()
{
DataSet ds = GetDataSetForTabs();
RadTabStrip1.AppendDataBoundItems = true;
RadTabStrip1.DataSource = ds;
RadTabStrip1.DataTextField = "QuesType";
RadTabStrip1.DataValueField = "QuesTypeID";
RadTabStrip1.DataBind();
// Remove it accordian from the page before adding it to
// a new ControlCollection
Page.Controls.Remove(Accordian1);
RadPageView pv = new RadPageView();
pv.Controls.Add(Accordion1);
RadMultiPage1.PageViews.Add(pv);
}
