I'm able to update the database fine, but how do I get the current information extracted from the database into the Edit textboxes.
This is my current code:
<asp:ListView ID="ListView1" runat="server" DataSourceID="Details">
<ItemTemplate>
<div class="col-xs-11">
<asp:Label ID="passwordname" runat="server"
Text="Current Password:" />
<asp:Label ID="password" runat="server"
Text='<%# Eval("Password") %>' />
</ItemTemplate>
</asp:ListView>
<asp:TextBox ID="editpassword" runat="server"
placeholder='<%# Eval("Password") %>' Text="New Password">
</asp:TextBox>
How do I get the textbox editpassword to show the current password stored?
Did you try binding the Value of the asp:TextBox?
Also, instead of using Eval(), consider model binding.
<asp:ListView ID="ListView1" runat="server"
DataSourceID="Details" ItemType="MyNamespace.MyClass">
<asp:TextBox ID="editpassword" runat="server"
Value='<%# BindItem.Password %>' Text="New Password">
</asp:TextBox>

Required Field Validator not working properly in gridview
I work in ASP.NET c# and MySQL database.
I need to make the required field of this DropDownList on FooterTemplate, but Required Field Validator not working.
Why ?
My code:
<FooterTemplate>
<asp:ImageButton ID="imgbtnInsert" runat="server" CommandName="Insert" ImageUrl="/images/icon_2.gif"
ToolTip="Add" OnClientClick="return confirm('Confirm?');" />
</FooterTemplate>
<FooterTemplate>
<asp:DropDownList ID="txtIDDTES" runat="server" CssClass="ddl_Class_new">
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rtxtIDDTES" runat="server" ControlToValidate="txtIDDTES"
ErrorMessage="***" Text="*" Display="Dynamic" ValidationGroup="Validation1"
SetFocusOnError="true" EnableClientScript="true"></asp:RequiredFieldValidator>
</FooterTemplate>
<asp:ValidationSummary ID="Validation1" ValidationGroup="Validation1" runat="server" ShowMessageBox="true" />
Can you please help me figure out the problem?
Thanks in advance.
Try this :
<form id="form1" runat="server">
<div>
<asp:ValidationSummary ID="ValidationSummaryTop" runat="server" ShowMessageBox="true" ShowSummary="false" />
...
<FooterTemplate>
<asp:DropDownList ID="txtIDDTES" runat="server" CssClass="ddl_Class_new">
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rtxtIDDTES" runat="server" ControlToValidate="txtIDDTES"
ErrorMessage="***" Text="*" Display="Dynamic"></asp:RequiredFieldValidator>
</FooterTemplate>
<asp:DataList ID="DataListDziennik" runat="server"
DataSourceID="SqlDataSourcePrzedmioty">
<ItemTemplate>
<asp:Label ID="LabelPrzedmiot" runat="server" Text='<%# Eval("przedmiot") %>' />
...
<asp:DataList ID="DataListOceny" runat="server"
DataSourceID="SqlDataSourceOceny"
RepeatDirection="Horizontal"
OnItemCommand="DataListOceny_ItemCommandOceny"
OnEditCommand="DataListOceny_EditCommandOceny">
<EditItemTemplate>
<asp:TextBox ID="TextBoxOcena" runat="server" Text='<%# Bind("lista") %>' />
<td><asp:Button ID="ButtonZapisz" CommandName="Update" runat="server" Text="Zapisz" /></td>
</EditItemTemplate>
<ItemTemplate>
<asp:TextBox Width="20" ID="TextBoxOcena" ReadOnly="true" Text='<%# Eval("lista") %>' runat="server"></asp:TextBox>
<td><asp:Button ID="ButtonEdytuj" CommandName="Edit" runat="server" Text="Edytuj" /></td>
</ItemTemplate>
</asp:DataList>
</td>
</ItemTemplate>
When I write this in code behind:
protected void DataListOceny_EditCommand(object source, DataListCommandEventArgs e)
{
DataListOceny.EditItemIndex = e.Item.ItemIndex;
DataListOceny.DataBind();
}
Visual Studio tells me that DataListOceny does not exist in current content. I just want to be able edit items on DataListOceny after clicking the "edit" button, please give me full code in code behind part...
for edit DataListOceny .
What you asking is same like the below thread.. You need to find the DataListOceny Control on each row of DataListDziennik to bind it

And Here is some good example on the same

I'm trying to get the original object back from a listview, when I click on the button.
I thought it was in e.Item.DataItem but that always seems to be null.
<form runat="server">
<asp:ListView ID="ListList" runat="server">
<ItemTemplate>
<asp:TextBox ID="tbCompanyName" runat="server" Text='<%# Eval("CompanyName") %>'></asp:TextBox>
<asp:TextBox ID="tbEmailAdress" runat="server" Text='<%# Eval("EmailAddres") %>'></asp:TextBox>
<asp:DropDownList ID="ddlAccountManagers" AutoPostBack="True" runat="server" />
<asp:Button runat="server" Text="Create or Update Account" CommandArgument='<%# Container.DataItem.ToString() %>' />
<br />
</ItemTemplate>
</asp:ListView>
</form>
private void ListList_ItemCommand(object sender, ListViewCommandEventArgs e)
{
}
You need to keep the original datasource in session and get the real values while clicking a button.
I want to create a table as below to interact with database to retrieve, delete, update data.
My output in design view is very messy. And when i try to run the page i receive the following error:
Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.
Please advise me for enhancement based on below data table and my coding.
.aspx:
<div class="modal-bg">
<asp:GridView ID="GridView1" runat="server" EnableEventValidation="false"
BackColor="White" BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px"

<button id="newuserbutton" onclick="return newuserbutton_onclick()">

Thank you for helps.
Did you actually try to place your control inside the <form runat="server"></form> tags?
Surround your html code with tag => <form runat="server"> ... </form>
I am using Ajax Calendar for date picker. when i click the calendar image the page will get postback but the calendar popup windows is not getting popup. How to resolve this problem?

no need to use image button for calendar.
You are just missing a Property of CalanderExtender PopupButtonID. try the following
<asp:TextBox ID="txt_FromDate" runat="server" AutoPostBack="True"
ontextchanged="txt_FromDate_TextChanged">
</asp:TextBox>
<asp:ImageButton ID="ibtnFromDate"
ImageUrl="~/_layouts/images/PayrollImages/calendar.gif"
ImageAlign="Bottom" runat="server"/>
<cc1:CalendarExtender ID="cal_FromDate" PopupButtonID="ibtnFromDate"
runat="server" PopupButtonID="ibtnFromDate"
TargetControlID="txt_FromDate" Format="MM/dd/yyyy">
</cc1:CalendarExtender>
