I need to create a merged cells type functionality (like http://www.telerik.com/community/forums/thread/b311D-ccatm.aspx) - this code checks through items and hard codes a column name.  How can I loop through all columns, checking if the previous column's value is equal to the current items?  I do not want to hard code column names.

Hello Samantha,

You can use the RadGrid1.MasterTableView.RenderColumns collection, to get a reference to the collection of all rendered columns in the control- autogenerated and statically declared.

All the best,

Yes I know, but I am having difficulty combining the code to loop through the columns, and then the cells.  Can you post a code snippet?

Hello Samantha,

The code to iterate through all the rows in the control, and within each row, through all the cells, bases on the unique name of the column to which this cell belongs, would look like this:

.cs
 protected void RadGrid1_PreRender(object sender, EventArgs e)  
    {  
        foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)  
        {  
            foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)  
            {  
                if (column is GridBoundColumn)  
                {  
                    dataItem[column.UniqueName].Text = "test";  
                }  
            }  
        }  
    } 

I hope this helps.
