I am facing a strange problem. Two of my textboxes in asp.net are showing the default text, but there is no default value is set not even in the .cs file.
Here is the the code for a textbox:
<tr>
<td>
<asp:TextBox ID="txtName" runat="server" ValidationGroup="reg" Height="32px" Width="155px"
Style="border: 1px solid #999; background-color: #eee; width: 250px; height: 25px"
type="text"></asp:TextBox>
</td>
<td>
<asp:RequiredFieldValidator runat="server" ControlToValidate="txtName" Display="Dynamic"
ValidationGroup="reg" ErrorMessage="Please fill your name as your Id"></asp:RequiredFieldValidator>
</td>
</tr>

Please add one of the following two combinations to your code
//do not change whole form tag, just add the autocomplete part
<form autocomplete="off">
//....
</form>
OR
add this to your elements directly
<asp:TextBox id="yourid" runat="server" autocomplete="off">
</asp:TextBox>
I think it might just be good practice to call the Clear() method in your Page_Load() if (!Page.isPostBack) and might solve your problem?
if (window.getSelection)
window.getSelection().removeAllRanges();
else if (document.selection)
document.selection.empty();

A question that I have is this:
If you are starting with an empty string for the SelectedValue, why don't you check the ensure that string.IsNullOrEmpty() fails for the value in question? The Page.IsValid() method will return "true" because, as far as it is concerned, the information that it uses to determine whether the Page is validated is complete.
And this part is free: (IMHO) if you are going to use a ValidationGroup, use a ValidationSummary as well. That way, you don't have to worry about individual labels
I have a link button as follow
<asp:LinkButton ID="LinkButtonSearchClient" PostBackUrl="~/UI/clients.aspx" runat="server">Recherche </asp:LinkButton>
i want get a query string from it
<asp:LinkButton ID="LinkButtonSearchClient" PostBackUrl="~/UI/clients.aspx?id=12" runat="server">Recherche </asp:LinkButton>
and the id value comes from the source code
public string ID
{
get { return ViewState["id"]; }
}
To get the value on page load (in the backend .cs file) :
protected void Page_Load(object sender, EventArgs e)
{
var id = Request.QueryString["id"];
if (id != null)
{
// use id
}
}
Or you might want to put the id into the link (in the html) :
<asp:LinkButton ID="LinkButtonSearchClient" runat="server"
NavigateUrl='<%# String.Format("~/UI/clients.aspx?id={0}", Eval("ID"))%>'
Text='Recherche'></asp:LinkButton>
You probably do not need a postback, look here : PostbackUrl vs NavigateUrl
Try this,
public string ID
{
get { Request.QueryString["id"]; }
}
Edit : In your page load set your postback url like this, access postbackurl in server side
LinkButtonSearchClient.PostBackUrl = "~/UI/clients.aspx?id=" + this.ID;
See my following example :
in design as follow
<asp:HyperLink ID="HLink" runat="server"
NavigateUrl='<%#"Mobiles_Details.aspx?ID=" + Eval("ID") %>' Text='<%#
Bind("Name") %>' Height="70px" Width="200px" Font-Bold="true" Font-
Size="10pt" Font-Names="Times New Roman" />
In coding the class Mobiles_Details is:
public partial class Mobiles_Details : System.Web.UI.Page
{
public string constr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
try
{
Session["UserID"] = "100";
//int ID = 102;
int ID = Convert.ToInt32(Request.QueryString["ID"].ToString());
Session["Product_ID"] = ID;
if (Session["UserID"] == null || Session["UserID"].ToString() == string.Empty)
{
Response.Redirect("Login.aspx", false);
}
else
{
if (ID != null)
{
DataTable dt = Load_Items_ID(Convert.ToInt32(Session["UserID"].ToString()), ID);
lbl_Name.Text = dt.Rows[0]["Name"].ToString();
lbl_Price.Text = dt.Rows[0]["Price"].ToString();
lbl_Details.Text = dt.Rows[0]["Details"].ToString();
img_Product.ImageUrl = dt.Rows[0]["image"].ToString();
}
}
}
catch (Exception ex)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "popup", "alert('An Error has been occured ');" + ex.ToString(), true);
}
}

i want to image in gridview
bind the image tag inside the gridview dynamically
by giving the path dynamically
<asp:Image ID="image" Style="width:100px; height:100px;" runat="server" ImageUrl='<%# "~/folder/subfolder/" + Eval("id") +"."+ Eval("imagetype") %>' />
and the method for binding the gridview
protected void GetDayoffer()
{
gridview1.DataSource = bl.method();
gridview1.DataBind();
}
hope this will help you or recovert the bytes into image again and bind it into gridview
I am searching and posting a lot in this issue,but could not get the satisfactory answer.I wanted to make sure that whenever I am making a call to server the value of Textbox should be the one which is the most updated one.
But when I am making the call to server the old value of the textbox persists.I know it is something to do with the postback,but I am not getting the exact way to get the updated value of textbox in my .cs file.
Please tell me what are the necessary steps that I should take to always get the latest value of the textbox.
Here is my code which is not working:
protected void Page_Load(object sender, EventArgs e)
{
int contentID = Convert.ToInt32(Request.QueryString["contentid"]);
if (contentID != 0)
{
if (!this.IsPostBack)
{
getContentBody(contentID);
TextBox1.Text = content;
msg_lbl.Text="Inside not PostBack";
}
else
{
getContentBody(contentID);
TextBox1.Text = content;
msg_lbl.Text="Inside PostBack";
}
}
else
Response.Write("Invalid URL for article");
}
public void getContentBody(int contentID)
{
try
{
//////////////Opening the connection///////////////
mycon.Open();
string str = "select content from content where contentID='" + contentID + "'";
//Response.Write(str);
MySqlCommand command1 = mycon.CreateCommand();
command1.CommandText = str;
dr = command1.ExecuteReader();
if (dr.Read())
{
content = dr[0].ToString();
}
}
catch (Exception ex)
{
Response.Write("Exception reading data" + ex);
}
finally
{
dr.Close();
mycon.Close();
}
}
protected void Button2_Click(object sender, EventArgs e)
{
//string textboxvalue = Request.Form[TextBox1.UniqueID];
mycon.Open();
string query = "update content set content='" +TextBox1.Text + "' where contentID= '"+contentID +"'";
msg_lbl.Text = query;
try
{
MySqlCommand command1 = mycon.CreateCommand();
command1.CommandText = query;
command1.ExecuteNonQuery();
msg_lbl.Text = "text" + TextBox1.Text;
}
catch (Exception ex)
{
msg_lbl.Text = "Exception in saving data" + ex;
}
finally
{
mycon.Close();
}
}
Here is my aspx page code:
<asp:TextBox ID="TextBox1" runat="server" Height="500px"
TextMode="MultiLine" Width="90%" AutoPostBack="True"></asp:TextBox>
</p>
<p>
<asp:Button ID="Button1" runat="server" Text="Delete post" />
<asp:Button ID="Button2" runat="server" onclick="Button2_Click"
Text="Save changes" />
<asp:Button ID="Button3" runat="server" Text="Cancel" />
</p>
Please also tell me the reason why it is not working and how I can make it work.
Thanks,

According to the ASP.NET's life cycle, Page_Load executes before Button2_Click, so you have to show your updated text in the Button2_Click:
protected void Page_Load(object sender, EventArgs e)
{
contentID = Convert.ToInt32(Request.QueryString["contentid"]);
if (contentID != 0)
{
if (!this.IsPostBack)
{
getContentBody(contentID);
TextBox1.Text = content;
msg_lbl.Text = "Inside not PostBack";
}
}
else
Response.Write("Invalid URL for article");
}
public void getContentBody(int contentID)
{
try
{
//////////////Opening the connection///////////////
mycon.Open();
string str = "select content from content where contentID='" + contentID + "'";
//Response.Write(str);
MySqlCommand command1 = mycon.CreateCommand();
command1.CommandText = str;
dr = command1.ExecuteReader();
if (dr.Read())
{
content = dr[0].ToString();
}
}
catch (Exception ex)
{
Response.Write("Exception reading data" + ex);
}
finally
{
dr.Close();
mycon.Close();
}
}
protected void Button2_Click(object sender, EventArgs e)
{
//string textboxvalue = Request.Form[TextBox1.UniqueID];
mycon.Open();
string query = "update content set content='" + TextBox1.Text + "' where contentID= '" + contentID + "'";
msg_lbl.Text = query;
try
{
MySqlCommand command1 = mycon.CreateCommand();
command1.CommandText = query;
command1.ExecuteNonQuery();
getContentBody(contentID);
TextBox1.Text = content;
msg_lbl.Text = "text" + TextBox1.Text;
}
catch (Exception ex)
{
msg_lbl.Text = "Exception in saving data" + ex;
}
finally
{
mycon.Close();
}
}
Ok I am using the code below in file called autocomplete.asmx (web service file) my main question is do I need to create a different web service for every field I want my auto complete to work for? IE maybe I would like to have the Company Name pulled out instead of country, but another time maybe name, now I know this just involves changing the select statement but How could I go about doing this so that depending on what field it is, it knows what select statement to use?
Thanks
public class AutoComplete : System.Web.Services.WebService
{
[WebMethod]
public string[] GetCountriesList(string prefixText)
{
DataSet dtst = new DataSet();
SqlConnection sqlCon = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
string strSql = "SELECT CountryName FROM Tbl_ooo WHERE CountryName LIKE '" + prefixText + "%' ";
SqlCommand sqlComd = new SqlCommand(strSql, sqlCon);
sqlCon.Open();
SqlDataAdapter sqlAdpt = new SqlDataAdapter();
sqlAdpt.SelectCommand = sqlComd;
sqlAdpt.Fill(dtst);
string[] cntName = new string[dtst.Tables[0].Rows.Count];
int i = 0;
try
{
foreach (DataRow rdr in dtst.Tables[0].Rows)
{
cntName.SetValue(rdr["CountryName"].ToString(), i);
i++;
}
}
catch { }
finally
{
sqlCon.Close();
}
return cntName;
}
}
Yes, you can use same webservice webmethod to populate country and company.
For that you want to use ContextKey property in ajax AutoCompleteExtender control
Below is the sample Code
Markup :
Search
<asp:TextBox ID="txtSearch" CssClass="textBlackBold" runat="server" Width="350px"></asp:TextBox>
<asp:DropDownList ID="ddlType" runat="server" AutoPostBack="True" onselectedindexchanged="ddlType_SelectedIndexChanged">
<asp:ListItem Value="0">Country</asp:ListItem>
<asp:ListItem Value="1">Companies</asp:ListItem>
</asp:DropDownList>
<asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server"
CompletionListCssClass="autocomplete_completionListElement"
CompletionListItemCssClass="autocomplete_listItem"
CompletionListHighlightedItemCssClass="autocomplete_highlightedListItem"
EnableCaching="true" ContextKey="Products" UseContextKey="true"
TargetControlID="txtSearch" MinimumPrefixLength="1"
ServiceMethod="GetInfo" ServicePath="~/WebService.asmx" >
</asp:AutoCompleteExtender>
Code Behind C# Code :
protected void ddlType_SelectedIndexChanged(object sender, EventArgs e)
{
string strContextKey = "";
if(ddlType.SelectedValue.ToString() == "0")
strContextKey = "Country";
else
strContextKey = "Companies";
AutoCompleteExtender1.ContextKey = ddlType.SelectedItem.Text;
}
WebService Code :
[WebMethod]
public string[] GetInfo(string prefixText, string contextKey)
{
DataSet dtst = new DataSet();
SqlConnection sqlCon = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
string strSql = "";
if (contextKey == "Country")
{
strSql = "SELECT CountryName FROM Tbl_ooo WHERE CountryName LIKE '" + prefixText + "%' ";
}
else if(contextKey == "Companies")
{
strSql = //Other SQL Query
}
SqlCommand sqlComd = new SqlCommand(strSql, sqlCon);
sqlCon.Open();
SqlDataAdapter sqlAdpt = new SqlDataAdapter();
sqlAdpt.SelectCommand = sqlComd;
sqlAdpt.Fill(dtst);
string[] cntName = new string[dtst.Tables[0].Rows.Count];
int i = 0;
try
{
foreach (DataRow rdr in dtst.Tables[0].Rows)
{
cntName.SetValue(rdr[0].ToString(),i);
i++;
}
}
catch { }
finally
{
sqlCon.Close();
}
return cntName;
}
