Multiple controls with the same ID '0_0' were found. FindControl requires that controls have unique IDs.
posted

I have attached a small project to reproduce this problem.

I have a WebDataGrid with two template columns, the first template column is a checkbox to indicate if row is selected, also in the header there is a checkbox to select all rows including the rows in all pages if more than one page, but every time I click in any checkbox I'm getting following error:

Multiple controls with the same ID '0_0' were found. FindControl requires that controls have unique IDs.

Please see attached zip file.

Thanks

    Hello Oscar,

    I was able to test the sample application you attached.  By adding the following check in the PopulateGrid event for a PostBack, the error should not occur:

              private void PopulateGrid(DataSet ds)
              {
                     if (!IsPostBack)
                     {
                              AuditDataWebGrid.DataSource = ds;
                              AuditDataWebGrid.DataBind();
                              ViewState.Add("DataSet", ds);
                     }
              }

    Please try the above code and let me know of your results.
