Hello

I have a gridview for which I have used SqlDatasource. Now, I want to use datatable as a datasource, while doing so it is giving an error: Both DataSource and DataSourceID are defined. Remove one definition.

To resolve it, I have written the following code that is perfectly working

C#

GVBrand.DataSourceID = string.Empty;
GVBrand.DataSource = dt;
GVBrand.DataBind();

I found that, when I click edit or delete button, then it gives the following error:
Sys.WebForms.PageRequestManagerServerErrorException: The GridView 'GridView1' fired event RowEditing which wasn't handled.

Please help me, as I have no solution for that.
Thanks in advance.

Solution 1

This is a different error. Error message is self explanatory.Row editing event is not handled in the code behind. Handle that event.

edit,update and delete is handled automatically as i have used sql datasource it was working properly but when i have put the above code its not working and giving the error

But if you use DataSource you should handle it. handle it and check whether it is working or not.
