[Solved] Grid data resets after showing/hiding filter row

[Chris LaFrancis]

I have 2 image columns whose url's are based on the value of another column and an upper and loer limit that the user can select from a rad window.
The Rad window is called from the rad grid and when it closes it updates the image columns based on the values the user selects.
I also have server side code that shows or hides the filter row. At the end it calls the rebind() method to show or hide the filter row.
My problem is that when it does the rebind I lose the limits the user set as well as the image url's because it goes back to the way it was when it was originally loaded.
What can I do to get the grid to stay the way it was and show or hide the filter row?
Thank you.

Protected Sub GrdPoints_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) _
                     Handles GrdPoints.ItemCommand

        If e.CommandName = "PointsFilter" Then
            If GrdPoints.MasterTableView.AllowFilteringByColumn = False Then
                GrdPoints.MasterTableView.AllowFilteringByColumn = True
            Else
                GrdPoints.MasterTableView.AllowFilteringByColumn = False
            End If
            GrdPoints.MasterTableView.Rebind()
        End If
    End Sub

Hi Chris,

In such a setup, when the control is rebound, the settings which you have applied will be removed.
This behavior is expected.
One possible option in this case, would be to use custom code and logic to handle the filter item visibility.
For example, you can have a hidden input on the page, which will hold a true/false value, indicating whether the filter menu should be shown. Then, in the gridCreated event handler, you can access the hidden input, check its value, and hide/show the filter item accordingly.
I hope this suggestion helps.

Kind regards,
