EnableHeaderContextMenu column hiding problem

[Dheeraj]

Hi,
       I have a column in grid which I am hiding (Display="false") from users,and on click of a button I am accesing values from that column.I am using  HeaderContextMenu, form which user will be able to select and unselect the column(for personalization perpose i am giving this option to user).
                              The problem is that the hidden columns are also visible in  HeaderContextMenu.I want that those hidden columns should not come in  HeaderContextMenu. Please suggest me How to remove HeaderContextMenu - column values.

Regards,
Dheeraj

Hi Dheeraj,

In order to achieve your goal, you can handle the grid header context menu ItemCreated event. There hide the item which corresponds to the column you want to be always visible. Your code should resemble the below:

protected void Page_Load(object sender, EventArgs e)
{
    RadGrid1.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
}
void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
{
    if (e.Item.Value.Contains("OrderID"))
    {
        e.Item.Visible = false; //hide the OrderID column
    }
}

Give it a try and let me know if it works for you.
