RadGridView Summary row

Hello Siddharth,

Thank you for contacting us.

If I have correctly understood your scenario, you want to have a summary row for a column that is not visible in the RadGridView. In this case, you will need to create a custom GridViewSummaryItem. You can override its Evaluate method where you can get the values of the hidden column and make your calculations.

To better demonstrate what I have in mind, I have created a sample project and attached it here. The RadGridView has two columns. The first one shows an integer value and it is hidden. The summary is set in the second column. However, in the Evaluate method of the custom GridViewSummaryItem class, I am calculating the values of the first column. Here is the result:

Here is when the first column is not hidden:

I hope that this approach will work for you.
