RadGridView: Header check box get checked on the second checked data row
Hi

Note : Issue in Current version of Telerik (2020.1.218.40)

On cheked of GridViewCheckBoxColumn (Multiple rows) in GridView grdFrReview_HeaderCellToggleStateChanged fires and header checkbox get checked. Header checkbox should check only if all check-boxes of current page checked, otherwise header checkbox should not checked. This was working fine in my previous version of Telerik (2018.3.1016.40).

In the screenshot shown i have checked 1st and then 2nd row of grid, you can see its headercheckbox status has been checked.

Hello Suresh,

To workaround the issue I can suggest to set the Checked property of the columns after binding the grid as shown below:

 private void Form1_Load(object sender, EventArgs e)
 {
     try
     {
         BindColumns();
         radGridView1.DataSource = FillDatatoGrid();
         GridViewCheckBoxColumn chkSelectAll = (GridViewCheckBoxColumn)this.radGridView1.Columns["SelectAll"];
         chkSelectAll.Checked = Telerik.WinControls.Enumerations.ToggleState.On;
         chkSelectAll.Checked = Telerik.WinControls.Enumerations.ToggleState.Off;
     }
     catch (Exception ex)
     {
         throw ex;
     }
 }

I hope this helps.

Regards,
Nadya
