Hello,

1.
      You can merge the cells having same values using the following code:

C#:

    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        for (int rowIndex = RadGrid1.Items.Count - 2; rowIndex >= 0; rowIndex--)
        {
            GridDataItem row = RadGrid1.Items[rowIndex];
            GridDataItem previousRow = RadGrid1.Items[rowIndex + 1];

            for (int i = 0; i < row.Cells.Count; i++)
            {
                if (row.Cells[i].Text == previousRow.Cells[i].Text)
                {
                    row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 : previousRow.Cells[i].RowSpan + 1;
                    previousRow.Cells[i].Visible = false;
                }
            }
        }
    }

In this example, if a cell value is the same as a value in the next (lower) row, then its RowSpan is increased and the lower cell is made invisible.

2.
       By obtaining a reference to a RadWindow component, you can call any function that is defined in the parent window. Use the BrowserWindow property to reference the parent window .

javascript on content window:

function GetRadWindow()
{
  var oWindow = null;
  if (window.radWindow) oWindow = window.radWindow;
  else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
  return oWindow;
}
function CallFnOnParent()
  {
       GetRadWindow().BrowserWindow.CalledFn();
  }

And the function named 'CalledFn' should be defined on parent page, with the code to reload the page.
javscript on parent page:

function CallFn()
{
    window.location.reload(true);
}

All the best,
Shinu.

Shinu ,thanks.

en,About the question 2, iImet another questions.
1. In the server-side code,How do  I open the radwindow?
2. For the window opened ,I have a  "<asp:button runat='server'>,How do  I close the current window when I clicking the button at server side after I executed persisting operation(such as update a row in the table)?

Hello,

1.
The following code will help you in opening the window from code behind.

C#:

    protected void Button1_Click(object sender, EventArgs e)
    {
        RadWindow newwindow = new RadWindow();
        newwindow.ID = "RadWindow2";
        newwindow.NavigateUrl = "http://www.google.com"; // Set the url
        newwindow.VisibleTitlebar = true;
        newwindow.Behaviors = WindowBehaviors.Close; // Set the Behaviors
        newwindow.VisibleOnPageLoad = true;  // Set VisibleOnPageLoad property to True
        RadWindowManager1.Windows.Add(newwindow); // Add the window to WindowManager collection
    }

Setting Server-Side Properties for window is described in the documentation. Have look at this: Setting Server-Side Properties

2.
And for closing the window, add client method with code for closing the window. Call the method from server side as shown below.
C#:

ScriptManager.RegisterStartupScript(this, this.GetType(), "closeWindow", "CloseWindow();", true);

client side code:

    <script type="text/javascript">
        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow;
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
            return oWindow;
        }
        function CloseWindow() {
            GetRadWindow().close();
        }
    </script>

Hope this helps. :)

Best wishes,
Shinu.
