Hi everyone,

Let me explain my problem :

I have a rad grid with a lot of column so I have an horizontal scroll bar.
I Scroll to the last column of my grid, and I apply a filter. 
When the result of my filter show something there is no problem.
But if there is not data to show, my grid disappear and I have a blank page...

It always works (with data or no data for result) in the first columns of my grid, but not when I scroll to the right of my grid.

Many thanks for your help

Hi Marion,

The behavior that you are describing could be observed if you have set the MasterTableView ShowHeadersWhenNoRecords property to false.

Following is a simple RadGrid with enabled scrolling, which works correctly even if no records are returned after filtering:
<telerik:RadGrid runat="server" ID="RadGrid1" OnNeedDataSource="RadGrid1_NeedDataSource" Width="400px"
    AllowFilteringByColumn="true">
    <MasterTableView ShowHeadersWhenNoRecords="true"></MasterTableView>
    <ClientSettings>
        <Scrolling AllowScroll="true" />
    </ClientSettings>
</telerik:RadGrid>

And the code-behind:
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    DataTable table = new DataTable();
    int columnsCount = 20;
    int rowsCount = 30;
    for (int i = 0; i < columnsCount; i++)
    {
        table.Columns.Add("Column" + i, typeof(string));
    }
 
    for (int i = 0; i < rowsCount; i++)
    {
        table.Rows.Add();
        for (int z = 0; z < columnsCount; z++)
        {
            table.Rows[i][z] = "SomeValue" + i;
        }
    }
 
    (sender as RadGrid).DataSource = table;
}

If you continue to experience problems on your end, please provide elaborate which version of the controls you are using and what differs in your RadGrid settings from the above example.
