Hi Sathies,

Hope you are trying to access the controls in the NestedViewTemplate on expanding the master table. Try the following code snippet and see if it helps.

CS:

 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "ExpandCollapse")
        {
                GridDataItem item = (GridDataItem)e.Item;
                GridNestedViewItem nestedItem = (GridNestedViewItem)item.ChildItem;
                RadTextBox txtbx = (RadTextBox)nestedItem.FindControl("RadTextBox1");
               //to access the Text from the TextBox
                string strCurrentText = txtbx.Text;
               //to set text in RadTextBox
                txtbx.Text = "NewText";

        }
    }

Thanks

Hi Shinu,

Thanks, its works fine.
Is there any way to differentiate Expand and Collpase ie) I want to load data  during Expansion and save data when Collapsed.

Hi Sathies,

Try the following code snippet to achieve the desired scenario.

CS:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "ExpandCollapse")

{

//to save data when collapsed

if (e.Item.Expanded)

{

GridDataItem item = (GridDataItem)e.Item;

GridNestedViewItem nestedItem = (GridNestedViewItem)item.ChildItem;

RadTextBox txtbx = (RadTextBox)nestedItem.FindControl("RadTextBox1");

//to access the Text from the TextBox

string strCurrentText = txtbx.Text;

}

//to load data during Expansion

else if (!e.Item.Expanded)

{

GridDataItem item = (GridDataItem)e.Item;

GridNestedViewItem nestedItem = (GridNestedViewItem)item.ChildItem;

RadTextBox txtbx = (RadTextBox)nestedItem.FindControl("RadTextBox1");

//to set text in RadTextBox

txtbx.Text = "NewText";

}

}

}

Thanks
