Hello,
I am trying to divide the column header of some columns in two with the HtmlViewDefinition of the RadGridView. My table is not so complex for the moment but I just can't make it work....
I attached an Excel file screenshot to this message so you can have a look to what I want to do and below is the code I wrote so far:
I have a binding list full of data in it which I give to the radgridview and then I define the view and apply the view to the radgridview after updating it.
With this code, the radgridview look like the screenshot radgridview result.
Any idea how to display the data correctly into the radgridview?
Thanks,
LB

Hi Ludovic,
Thank you for contacting us.
Please note that RadGridView should contain columns for all cells represented in the view definition. So, you have to add columns first. There is a restriction in RadGridView which says that all columns should have unique name, so you have to change names of Date and Amount columns. You should use the HeaderText property of GridViewColumn to customize the header cell text.
When using HtmlViewDefinition, RadGridView repeats the header layout in all rows. So, you may prefer the ColumnGroupsViewDefinition instead. If this is the case, you can use the following code:
I hope this helps. If you need further assistance, do not hesitate to write back.

Hi Jack,
Thank you for your answer. I made it work in 2 minutes!
I was focusing on the view and wondering why it did not work. I created before HtmlViewDefinition and ColumnGroupsViewDefinition similar to what I posted but could not find out why it did not work. Actually I forgot to add the columns before applying the view.
Thanks again! I will create a more complex view now to fit what I want to do.

PS: I am just starting to use Telerik, hopefully soon I will understand how everything works.
