Hi azuana Mohamed,
Error Creating Control - ReportViewer1Failed to create designer 'Microsoft.Reporting.WebForms.ReportViewer, Microsoft.ReportViewer.WebForms, Version=22.214.171.124, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
Please check the ReportViewer version. According to the web.config file, it seems that you have installed the ReportView version 11.0.
From the error message, I suppose the version of the ReportViewer in the Toolbox is version 9.0.
So, I suggest you could try to re-install the ReportViewer Version 9.0 in your project.
please refer to the following thread:
Otherwise, you could try to re-install the ReportViewer version 11.0 in the Toolbox.
