Inserting Items in to the Footer

[Danny]

Hello all-

is there a way to assign values to footer items using an integer index?

If so, in what event would you do this?

Thanks in advance.

Hello Danny,

If you want to change the RadGrid footer item you need to handle ItemCreated event and check if e.Item is GridFooterItem. Then you could change its cells by using the columns UniqueName. For example:

void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
      GridFooterItem footerItem = e.Item as GridFooterItem;
      if (footerItem != null)
      {
          footerItem["columnUniqueName"].Text = "SomeValue";
      }
}

However if you want to change the GroupFooterItems you could try using the same approach or you could try using the GroupFooterTemplate. Online example of GroupFooterTemplate you could find here:
http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/headerandfootertemplates/defaultcs.aspx

I hope this helps.

All the best,

Thanks for the reply, Radoslav.

In gridview I'm able to add items to the footer in the OnRowDataBound event like this:

protected void gridview_OnRowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.Footer)
           {
               for(int i = 0; i < dt.columns.count; i++)
               {
                     e.Row.Cells[i].Text = someString[i];

So there's no way to assign the cells in the footer as integer indexes?  I have to use the column names?

Hi,

You can assign values to footer items using an integer index. But the column index starts at index '2' because GridExpandColumn and GridRowindicatorColumn are always in front of data columns. So the most recommended way is to change the value by using the column's UniqueName. Here is the sample code snippet I tried to assign footer cell text using index.

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridFooterItem)
    {
        string[] arr2 = { "one", "two", "three" };
        for (int i = 0; i < dt1.Columns.Count; i++)
        {
           int j = i + 2;
           e.Item.Cells[j].Text = arr2[i];
           j++;
        }
    }
}

Thanks,
Shinu.
