[Solved] Binding checkbox type cells in RadGridView with dynamic number of columns - any ideas?

[Geoff Davis]

Could you point us to any existing code or suggest if this hasn't been done before?

We have dynamically loaded the columns. The 1st column acts as a header column and rest of the columns are check box columns. Also, we have header row and rest of the rows are dynamically loaded. The check box columns establishes relationship between the header row and header column (like in matrix table). We would like to implement this in a RadGridView.

We have tried three things so far -

1. GridViewSelectColumn - but it doesn't have DatamemberBinding property to which we can bind to our property in DataContext

2 .GridViewDataColumn - but that requires defining the Datatemplate with control CheckBox withing it ( all under Resources section). Problem is that resources section we were not able to retrieve the column index property so that we could bind the isChecked (of Check box control) to desired property in Datacontext (which is array of boolean values). Our datacontext is Observable collection of Class which itself contains array of boolean values for the columns. Can we do a 2D binding of RadGridView :) ??

3. Use GridViewDataColumn but do not define any Datatemplate under resources and directly bind the property to value of GridViewDataColumn - this automatically built the check boxes within for each column and row. Problem here is the clunky behavior of the check box. The check box responds only to double click. That is, double clicking the check box puts the grid cell in to edit mode and then the check box value can be changed

Any suggestions?

Hi,

 Why not create your own custom column, override CreateCellElement and create/bind the CheckBox there? You can check this blog post for more info about custom columns.
