Grid scoll clearing checkbox and at a time it is checking only one checkbox inn grid

[Rajesh]

Hi,

I am facing some issues in datagrid checkbox column.

1. I have crated master template an having a checkbox column e.g and it has some child template as well which i create dynamically
           GridViewCheckBoxColumn1.EnableExpressionEditor = False
            GridViewCheckBoxColumn1.FieldName = "DeleteItem"
            GridViewCheckBoxColumn1.HeaderText = "Delete"
            GridViewCheckBoxColumn1.MinWidth = 20
            GridViewCheckBoxColumn1.Name = "radchkDelete"
            GridViewTextBoxColumn4.EnableExpressionEditor = False
It is allowing me to check only one checkbox(row) at a time and when i am trying to check another checkbox(row)  it is unchecking my previous checked column..why this..?
2.I am checking one checkbox and trying to scroll horizontally ..it is clearing my checked column...why this..?
3.I am using some events like
code:
  Private Sub rdgrdvSeachAddUpt_CellEditorInitialized(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles rdgrdvSeachAddUpt.CellEditorInitialized
            Dim lobjMessage As New Message
            Try

                Dim editor = TryCast(e.ActiveEditor, RadDropDownListEditor)
                If editor IsNot Nothing Then
                    Dim editorElement = TryCast(editor.EditorElement, RadDropDownListEditorElement)
                    If editorElement IsNot Nothing Then
                        If e.Column.Name = "radcmbCriteriaType" Then
                            AddHandler editorElement.SelectedIndexChanged, AddressOf editorElement_SelectedIndexChanged
                        End If
                    End If
                End If
            Catch objException As Exception
                Logger.Log(objException, lobjMessage)
                UIHelper.ShowMessage(lobjMessage)
            Finally
                lobjMessage = Nothing
            End Try
        End Sub
