Hi,

I have a DetailTables in my grid, and each row in the DetailTables has a checkbox.  I am strugging to loop through each row to see if the checkbox is selected or not.  I have tried looking for a suitable example but could not find any.  Here is my code:

protected void btnClientAccounts_Click(object sender, EventArgs e)
{
   foreach (GridDataItem item in rgResults.MasterTableView.DetailTables[0].Items)
   {
      CheckBox chkSelectAccount = (CheckBox)item.FindControl("chkSelectAccount");
   }
}

The item coun stays 0.  I'm not sure.

Please can some one help me?

Thanks
Brendan

Hi Brendan,

Try achieving the desired scenario as shown below.

CS:
protected void btnClientAccounts_Click(object sender, EventArgs e) 
   
  foreach (GridDataItem item in RadGrid1.MasterTableView.Items) 
        { 
            if (item.Expanded) 
            { 
 
                GridTableView nestedView = ((GridDataItem)item).ChildItem.NestedTableViews[0]; 
                foreach (GridItem childitem in nestedView.Items) 
                { 
                    CheckBox chkSelectAccount = (CheckBox)childitem.FindControl("chkSelectAccount"); 
                } 
                 
            } 
        } 
 


Regards
Shinu.

Thanks it works just fine.  Now the next question that I have is the following.  In the DetailTables I have set DataKeyNames="AcctNo".  Now how do I get this value back for each row?  I thought it would be something in the line of (which I used to get the parent row):

dataItem.GetDataKeyValue("AcctNo");

Please can you advise.

Thanks
Brendan

Hello Brendan,

You need to set the Name property of the DetailTable and then check for the property to get the DataKeyValues. Check out the code snippet below.
aspx:
<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" >        
  <MasterTableView DataSourceID="SqlDataSource1" Name="Master" >        
     <DetailTables> 
        <telerik:GridTableView DataKeyNames="Age" Name="Detail" DataSourceID="SqlDataSource1" runat="server">        
                
        </telerik:GridTableView> 
      </DetailTables>        
   </MasterTableView> 
</telerik:RadGrid> 

cs:
 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
    { 
        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Detail") 
        { 
            string strtxt = (e.Item as GridDataItem).GetDataKeyValue("Age").ToString(); 
        } 
    }

I need to loop through each row in DataTables to get the ID.  Here is my code, I need to loop through it when you click on the button:

foreach (GridDataItem item in rgResults.MasterTableView.Items)
{
   if (item.Expanded)
   {
      GridTableView nestedView = ((GridDataItem)item).ChildItem.NestedTableViews[0];

      foreach (GridItem childitem in nestedView.Items)
      {
         CheckBox chkSelectAccount = (CheckBox)childitem.FindControl("chkSelectAccount");
        
         if (chkSelectAccount.Checked)
         {
            // Get the account number
            // Here is where I am trying to get the account number
            //object acctInfo = childitem.OwnerTableView.DataKeyValues[0];
            Account account = new Account();
            //account.AccountNumber = 
         }
      }
   }
}

Hi Brendan,

Try the following code snippet to get the DatakeyValue for the checked items in  the Detail table on a button click.

CS:
 protected void Button1_Click(object sender, EventArgs e) 
    { 
 
        foreach (GridDataItem item in RadGrid2.MasterTableView.Items)  
        {  
            if (item.Expanded)  
            {  
  
                GridTableView nestedView = ((GridDataItem)item).ChildItem.NestedTableViews[0];  
                foreach (GridDataItem childitem in nestedView.Items)  
                {  
                    CheckBox chkSelectAccount = (CheckBox)childitem.FindControl("chkSelectAccount"); 
                    if (chkSelectAccount.Checked) 
                    { 
                        string StrKey = childitem.GetDataKeyValue("KeyName").ToString(); 
                    } 
                }  
                  
            }  
        }  
  
 
    } 


Thanks
Shinu.
