button inside SelectedItemTemplate of DataList

Question

0.00/5 (No votes)

See more:

I have a DataList and inside the SelectedItemTemplate there is a button.
<asp:Button ID="getDetails" runat ="server" Text ="Send Enquiry" CommandName ="SendEnquiry" Font-Names ="verdana" Font-Size ="8pt" Height ="20px" Width ="90px" />
When this button is clicked I should know wheather the event is raised by this button. For this purpose I had written the following code.

C#

protected void carList_ItemCommand(object sender, DataListCommandEventArgs  e)
   {
       try
       {
           if(e.CommandName =="SendEnquiry")
           {
               Label12.Text = "Send Enquiry";
           }
           else
           {
               Label12.Text ="Do not send";
           }
       }
       catch (Exception e1)
       {
           Label12.Text = e1.Message.ToString();
       }
    }

But when I click this button the above condition is never becoming true. Can anyone tell what is wrong.

Thanks in advance!

I have 3 textboxes inside the SelectedItemTemplate. I have to take the values of these textboxes and do some process when this button is clicked.

Solution 2

Convert the Asp:Button into an Asp:LinkButton. It will work.

That is:

<asp:LinkButton ID="getDetails" runat="server" Text="Send Enquiry" CommandName="SendEnquiry" Font-Names="verdana" Font-Size="8pt" Height="20px" Width="90px" />

Or, you have to use the UseSubmitBehavior="false" property for the Asp:Button, to make it work. That is:

<asp:Button ID="getDetails" runat="server" Text="Send Enquiry" UseSubmitBehavior="false" CommandName="SendEnquiry" Font-Names="verdana" Font-Size="8pt" Height="20px" Width="90px" />

The reason is, by default an Asp:Button renders an Submit button and DataList doest not work if the button has a Submit behaviour. So, you need to mark the UseSubmitBehavior="false"

Good luck :)

this is working.But I couldn't take the values of textboxes which are inside this selectedItemTemplate using the following code:

if(e.CommandName =="SendEnquiry")
{
TextBox t = (TextBox)e.Item.FindControl("userName");

Label12.Text = t.Text.ToString () +"Send Enquiry";
}

When giving UseSubmitBehavior="false", it is working. But I couldn't get values from textboxes

Yes, because, this time the values are not being submitted to the server. I would better suggest you to use LinkButton, instead of the Button.
