Finding Items in a Grid row on Button Click

[gupta gf]

      Hi,

                 In our project  many places we use RadControls. In that especially RadGrid is very frequent in use.
              For finding the RadGrid Selected row details( columns ) , we used to write like this as below
 
         This below radio button we placed in the ItemTemplate.

      <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
              <ItemTemplate>
                  <asp:RadioButton ID="rboAccount" runat="server" AutoPostBack="true" GroupName="myGroup"
                                                                            OnCheckedChanged="ToggleSelectedState" />
               </ItemTemplate>
      </telerik:GridTemplateColumn>

       foreach (GridDataItem item in rgSearchResults.MasterTableView.Items)
        {
            RadioButton radio = (RadioButton)item.FindControl("rboAccount");
            if (radio.Checked == true)
            {
                objCustomerContext.CustomerID = Convert.ToInt32(item.Cells[3].Text);
            }
        }

                       This works fine, but if maore records in the Grid, for finding the selected row details , it is taking more time. There is a      lot of performance issue.

         Can you please help me in this regard with a better performance oriented solution to find the values in the particular row.

 Thank you,
  Gupta

Hi gupta gf,

Try using the SelectedItems collection of the RadGrid control.

I hope this helps.

  Hi Tsvetoslav,

               Thank you very much for your reply.
  
            My scenario is , I have a check box or link button in the ItemTemplate  . For finding the Grid Predefined columns like(GridCheckboxColumn or GridButtonColumn) or for Client side , ur solution will work.

Can you please help me out in this scenarion. I mentioned the code below.          


 <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
              <ItemTemplate>
                  <asp:RadioButton ID="rboAccount" runat="server" AutoPostBack="true" GroupName="myGroup"
                                                                            OnCheckedChanged="ToggleSelectedState" />
               </ItemTemplate>
      </telerik:GridTemplateColumn>

I have a set of rows. If any user selects particular Radiobutton then in the code (server side) i want to retrieve the Radio button selected rows information .

Hi gupta,

Try out the following code wherein the NamingContainer(grid row) of the RadioButton is accessed on its CheckedChanged event:
c#:

protected void ToggleSelectedState(object sender, EventArgs e)
    {
        RadioButton rboAccount = (RadioButton)sender;
        if (rboAccount.Checked)
        {
            GridDataItem dataItem = (GridDataItem)rboAccount.NamingContainer;
            string strtxt = dataItem["BoundColumnUniqueName"].Text;
        }
    }

Thanks
Princy.

Hi princy,

          Thank you very much for Reply. The code which u have sent now will work if write in Checked changed event. at a time only one row details we can know from this. I have a scenario that , in a grid if user selects more than one row then for retrieving the Row details
i have written the below code

       foreach (GridDataItem item in rgSearchResults.MasterTableView.Items)
        {
            RadioButton radio = (RadioButton)item.FindControl("rboAccount");
            if (radio.Checked == true)
            {
                objCustomerContext.CustomerID = Convert.ToInt32(item.Cells[3].Text);
            }
        }

 From this I can get the all selected rows information.

 I think you have understood my problem.

  I am attaching the screen with this reply,

In that on Button Move to Selected account(s) , In Onclick event i have written the Above foreach loop.

 Instead of foreach, because it will take more execution time any other alternative to find the Selected rows information.

Thank you,
