custom filtering

[Regeesh Joseph]

Hai,

I have grid with data which binds on page load. I have 7 tabs. On clicking the tabs, data in the grid should filter based on the value of a hidden column in the grid. I dont want the filter text box and user inputing the filter text. Is there any way to do it?

Thanks & regards,
Regeesh

Hello Regeesh,

I hope the following demo will help you to get started.
Grid Filtered by Combo

In that demo, save the clicked tab value in a session and add SessionParameter to SqlDataSource's SelectParameters so that the grid will populate according to the tab selection made.

That will reduce the performance of the page. I want the grid loads initially and switching between the data inside the grid with tabstrip. Plz help me.

Hi Rageesh,

Another option you can adapt is setting the griditem visibility based on the cell value, which does not hit db every time when you click on the TabStrip.

Here you can find some sample code:

protected void RadTabStrip1_TabClick(object sender, Telerik.Web.UI.RadTabStripEventArgs e)
{
    foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
    {
        if (item["CompanyName"].Text != RadTabStrip1.SelectedTab.Value) // Check for the condition
        {
            item.Visible = false;
        }
        else
        {
            item.Visible = true;
        }
    }
}

Hai,

I want to call the event which is happening when we click on the filter menu item "contains" which custom filter value,  through code. Is there any way? Can you help.

Hi,


You can access the filter information in the ItemCommand event handler and then replace the filter expression based on RadTabStrip selection.
