  how to get the data bound to an instance of a user control

  Apr 09, 2012 05:31 PM|LINK

  Hello to all the pros....

  My name is elli and im doing some project for school, i will very much appreciate you advice.

  I have a number of instances of a user control in my aspx page. the data in the user control i get from a datalist.

  inside the control i have a button. what im trying to do is like that:

  when a user clicks the button, i want to find out what row from the datalist is presented in this specific control, and store it in, lets say, session.

  my problem right now is when i click the button, nothing happens, i tried just to put a simple Response.Redirect in the onButton_click in the code behind...

  im working on it already 2 days and im kinda lost.

   

  this is my user control ascx partial code: the image button is in the beggining

   

  <div id="video play button icon" style="height: 27px; width: 121px;
                          float: left"><asp:ImageButton ID="PlayButton" runat="server" ImageUrl="~/Search_Results_Images/search_Play_Button_Icon.png" onclick="PlayButton_Click" />
                      </div>
                      <div style="height: 27px; width: 22px; float: left">
                      </div>
                  </div>
                  <div style="height: 15px; width: 434px; background-color: transparent; float: left">
                  </div>
               
              </div>
          </div>
          
      </ItemTemplate>
      <SeparatorTemplate>
      <div style="width:84px"></div>
      </SeparatorTemplate>
      
  </asp:DataList>

  this is the ascx.sc code
   

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Text;
  using System.Data.SqlClient;
  using System.Data;
  using System.Configuration;
  public partial class SearchBullet : System.Web.UI.UserControl
  {
  
      protected void Page_Load(object sender, EventArgs e)
      {
          String tmpcmd;
          tmpcmd = (String)(Session["mainSearchQRY"]);
          SqlDataSource1.SelectCommand = "";
          SqlDataSource1.SelectCommand = tmpcmd;
  
  
      }
      protected void PlayButton_Click(object sender, EventArgs e)
      {
          Response.Redirect("Default2.aspx");
      }
  
  }

  thank you very much,

  elli

  Your mark-up says - PlayButton_Click

  And your cs file does not have it, rather it has - btnClick_Click.

  is it the case really, or is it just a typo?

  It seems you are rebinding your DataList in Page Load event.

  Its ok to keep it there, but try putting that code in -

  if (Page.IsPostBack == false)

  {

  --- move your rebind code here

  }

  Hi elli,

  please check your code-behind of user control, it should like this:

  protected void PlayButton_Click(object sender, ImageClickEventArgs e)
          {
              Response.Redirect("ShowProduct.aspx");
          }

  your parameter of the method is not currect.
