[Solved] Custom grid header row with combo boxes

[Andrew]

I want to create a row of combo boxes (one for each column) that is above the other rows of data in the Grid. The row needs to persist across pages.

The grid I use uses paging and horizontal scrolling. It is also bound to a datasource who's structure can change from one execution to the next. I use advanced data binding through the OnNeedDataSource event. I bind to a DataTable object.

Each combo box will hold the same data, and I will custom handle the logic of the cb's postback (as long as I can reference the value of  the header, or index for that column).

Can you suggest a way of implementing this?

I'm still new to the Telerik controls, so please help me out. Code samples would be appreciated.

Hello Andrew,

You can use the commandItem template to achieve the desired functionality.
I hope this is a feasible option for you.

If I place a series of combo boxes, one for each column in the grid, into the command item template, is it possible to have the combo boxes sized to the width of the columns (if the columns are auto sized)?

If client resizing of the columns is turned on, is it possible to have the combo boxes reflect those resize changes?

Hi Andrew,

There are two options to address this.
First, you can use template columns, and nest the relevant comboboxes in the header templates. Alternatively, you can nest the comboxes in a table in the command item, which would give you a chance to size it accordingly.
