GridView - Group Headers - Custom Template on GroupByExpression

[Michael]

Hi,

Is there any way I can use a template field or something similar so that I can have a custom formatted entry above the group.  I can do this by adding a single entry into the select fields of the group by GroupByExpression object.. and then changing the format string to include a table with the format I need..

The problem with this is that I only have access to one field ({0}) which is the one referenced in the FieldName of the object.. but I need access to other fields returned by the data source.

Any suggestions?

Thanks

Mike

Hello Michael,

This functionality is not readily supported by RadGrid, but you can always manually modify your GridGroupHeaderItem text to fit the data you need. This can be done in the ItemDataBound event of RadGrid, where you can get a reference to the GridGroupHeaderItem and mofiy its content:

void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridGroupHeaderItem)
    {
        GridGroupHeaderItem item = e.Item as GridGroupHeaderItem;
        item.DataCell.Text = item.DataCell.Text + " custom text";
    }
}

This way, your custom text would be any value you would need to reference in your grid data.

Hi Saravanan,

Try the following code snippet in itemDataBound event to add controls to GroupHeaderItem.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridGroupHeaderItem)
            {
                GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item;
                Button objButton = new Button();
                  objButton.CommandName = "Add";
                objButton.ID = "Button_Add";
                item.DataCell.Controls.Add(objButton);
                item.DataCell.Style["text-align"] = "right";
            }
        }
