I need to iterate through the rows and cells from code once the grid is already created and get the header text of each cell. How can this be accomplished?

Thanks!

Hello Joe,

If all you want is the header text for your cells, then you can simply iterate through the columns of the RadGrid and retrieve their header text values. All cells in a column will have the same header text value.

Here is a simple way to do that after the RadGrid.OnDataBound event is fired (which occurs after the data source has been bound to the grid):

protected void RadGrid1_DataBound(object sender, EventArgs e) 
    foreach (Telerik.Web.UI.GridColumn column in RadGrid1.Columns) 
    { 
        var headerText = column.HeaderText; 
 
        // Put the rest of your logic here... 
    } 

I hope this helps. If you have further questions please let me know.

Regards,
Kevin Babcock

Thanks, that helps but I still need to be able to do it as I am iterating through the grid. Here is what I have come up with so far but there are still problems:

If rgCoverages.Items.Count > 0 Then 
 
     gvRow = rgCoverages.items(rgCoverages.Items.Count - 1)  
 
     For Each myCell As Telerik.Web.UI.GridTableCell In gvRow.Cells  
 
          strHeader = rgCoverages.Columns(intCellIndex).HeaderText    
 
          intCellIndex += 1  
    
     Next 
 
End If 
 
 

Here I am trying to grab the last row in the gridview, iterate through the cells to find out which cells have checkboxes (i removed the code where I am trying to find the checkboxes because I need to get past this issue first) in them and then to find the header text of these cells so I know which type of coverage it represents (medical, dental, vision etc.) and finally to determine if the checkbox was checked. The grid is created dynamically and could have any number of combinations for coverages offered so I can't count on it always having the same structure.

The problem with the above code is that somehow there are more cells in this row then there are columns in the grid. I don't know why but for some reason it says that there are 8 cells in the row but only 6 columns in the grid, so I get an argument out of range exception.

Thanks again!

Hello Joe,

Please use RenderColumn collection instead Columns.
