Header Context Menu on Header left click

[Niraj]

Hi,

 Can I associate GridHyperLink or GridDateTime Column in the GridTemplate column?
I just want to change the header template, I dont want to change the item template. Is this possible..?
I am embedding a image button inside the header for each column. Can I have the header context menu on click event of this image button.?
If so, what is the CommandName for header context menu and CommandArgument for the same. ?

Hi,

 

I have used this code(in ItemDataBound Event) which was posted on one your forums.I also tried it on ItemCreatedEvent. But the problem is(in both cases) it is only putting the image button for only the first column . Can you explain this?
//if (e.Item is GridHeaderItem)
//{

 

 

 

// ImageButton button = new ImageButton();

 

 

 

// button.ID = "ContextButton" + i.ToString();

 

 

 

// i++;

 

 

 

// button.AlternateText = "ContextButton";

 

 

 

// button.ImageUrl = "1294371072_email.png";

 

 

 

// button.OnClientClick = "showMenu(this, event); return false;";

 

 

 

// e.Item.Cells[2].Controls.Add(button);

 

 

 

//}

Hello Niraj,

You need to loops through each column to add ImageButton for all the columns in RadGrid.

C#:

int i = 1;
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridHeaderItem)
    {
        foreach (GridColumn col in RadGrid1.Columns)
        {
            GridHeaderItem headerItem = (GridHeaderItem)e.Item;
            ImageButton button = new ImageButton();
            button.ID = "ContextButton" + i.ToString();
            i++;
            button.AlternateText = "ContextButton";
            button.ImageUrl = "1294371072_email.png";
            button.OnClientClick = "showMenu(this, event); return false;";
            e.Item.Cells[i].Controls.Add(button);
        }
    }
}

Thanks,
