How to remove GridViewSummaryRowItem from RadGridView.

[Mohammad]

Hi,

Background:

I am populate a grid on certain criteria which user selects within a form. When user press the Load Data button, the data is getting loaded into the RadGridView along with a SummaryRow on the top of the grid.

I have a clear data button which currently clears the grid by setting the DataSource property to null.

Issue:

When user hit the Clear Data button alothough it clears out all the data but leaves that Summary row on the top, which is an issue.

My question is - Is there a way to remove the GridViewSummaryRowItem or any way I can refresh the whole grid which removes the SummaryRow.

Thanks.
Regards
Mohammad

Hi Mohammad,

Thank you for writing.

I made a sample test according to your description and when I set the DataSource of the grid to null it shows the "No data to display" string and the rows, columns and the summary row are not displayed. Attached you can find a sample project demonstrating this.

However, you can always call the Clear method of the desired summary row collection:

this.radGridView1.SummaryRowsTop.Clear();

I hope that you find the provided information useful. Let us know if you have any other questions.
