EnableHeaderContextMenu

[sathies]

Hi,

Is  it possible to customize the EnableHeaderContextMenu? i.e.) There are four columns in a grid , suppose user hides the two columns.Next time when he see the grid it should only contains two columns which was selected previously but not  all.

Hello Sathies,

You can access the items in the context menu on ItemCreated/ItemDataBound events:

void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
{
   //your code
}
protected void RadGrid1_Load(object sender, EventArgs e)
{
    RadGrid1.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
}

Let us know if you need further assistance.

Hi Sathies,

You can try the following code snippet to access the Column names in the code behind.

CS:

 foreach (RadMenuItem item in RadGrid1.HeaderContextMenu.Items[7].Items)
        {
            int count=RadGrid1.HeaderContextMenu.Items[7].Items.Count;
            for (int i = 0; i <= count-1; i++)
            {
                string strName = RadGrid1.HeaderContextMenu.Items[7].Items[i].Value;
                string strColName = strName.Split('|')[1];
            }
            break;
        }
