GridView and EnableHeaderCheckBox

[Deepak]

Hello,

I created GridView with dataset and added two CheckBox type column. In telerik documenation, there is one method to add checkbox on Header

GridViewCheckBoxColumn includeColumn_ = new GridViewCheckBoxColumn();
           includeColumn_.DataType = typeof(int);
           includeColumn_.EnableHeaderCheckBox = true;

           GridViewCheckBoxColumn excludeColumn_ = new GridViewCheckBoxColumn();
           excludeColumn_.DataType = typeof(int);
         //  excludeColumn_.EnableHeaderCheckBox = true;

First post is not complete. Please ignore it. Apologies. 

I created GridView with dataset and added two CheckBox type column. In telerik documenation, there is a method to add checkbox on Headers of a grid.

1.GridViewCheckBoxColumn includeColumn_ = new GridViewCheckBoxColumn();
2.includeColumn_.DataType = typeof(int);
3.includeColumn_.EnableHeaderCheckBox = true;
4.
5.GridViewCheckBoxColumn excludeColumn_ = new GridViewCheckBoxColumn();
6.excludeColumn_.DataType = typeof(int);
7.excludeColumn_.EnableHeaderCheckBox = true;

 

Now when i use this code i get an error(See attached file). It seems like i cannot use two HeaderCheckbox at a same time. 

 

Is this possible ?

 

Thanks and Regards,

Deepak

Hello Deepak,

It is possible to use more than one checkbox column with enabled header checkbox. The reason for the exception is somewhere else. Could you please share the entire code used for binding the grid and adding the columns?

I am looking forward to your reply.

Hi Deepak,

I already tested this but there is no exception on my side (see attached video). This is why I have asked you for the rest of the code.

I am looking forward to your reply.
