Hello Kaushal,

To achieve the desired functionality you could try using the following approach:
On client side OnColumnDblClick you could get the column unique name and change the cssClass of the column's header:
ASPX

<telerik:RadGrid runat="server" ID="RadGrid1">
  <ClientSettings>
    <ClientEvents OnColumnDblClick="OnColumnDblClick" OnColumnClick="OnColumnClick" />
  </ClientSettings>
</telerik:RadGrid>

JavaScript

function OnColumnDblClick(sender, eventArgs)
{
     var columnUniqueName = eventArgs.get_gridColumn().get_uniqueName();
     alert(columnUniqueName);
     var oldClass = eventArgs.get_gridColumn().get_element().className;
     eventArgs.get_gridColumn().get_element().className = oldClass + " doubleClickedColumnHeader";
}

CSS

<style>
 .doubleClickedColumnHeader
 {
    background-color: Red !important;
    background-image: none !important;
 }
</style>

On OnColumnClick you could revert the background color of the header:
JavaScript

function OnColumnClick(sender, eventArgs)
{
    eventArgs.get_gridColumn().get_element().className = eventArgs.get_gridColumn().get_element().className.replace(" doubleClickedColumnHeader", "");
}

Also you could fire grid's command from client and on server in RadGrid1_ItemCommand you could hide the column by its unique name:
JavaScript

$find("<%= RadGrid1.ClientID %>").get_masterTableView().fireCommand("customCommand",columnUniqueName);

ASPX.CS

void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == "customCommand")
        {
            foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
            {
                if (column.UniqueName.ToString() == e.CommandArgument.ToString())
                {
                    column.Visible = false;
                }
            }
        }
    }

Additionally I am sending you a simple example which demonstrates the desired functionality. Please check it out and let me know if it helps you.
