[Solved] Validation Of MasterTableViewEditFormControls

[Jon Adkins]

All,

I currently have controls inside of a custom template that need to pass a strict validation process. For instance, there are two datetime pickers within the Template whose values need to be passed to a custom validation function. The problem that I am getting is how to pass those values to say the following customvalidator servervalidate routine. I seem to only be able to reference the items in one of the radgrid commands as shown below:

Protected Sub RadGrid2_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid2.UpdateCommand
        If TypeOf e.Item Is GridEditableItem Then
            Dim editedItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
            Dim StartTime As RadDateTimePicker = CType(editedItem.FindControl("RadDateTimePickerStart"), RadDateTimePicker)

            Dim EndTime As RadDateTimePicker = CType(editedItem.FindControl("RadDateTimePickerEnd"), RadDateTimePicker)
            Dim LeaveType As RadComboBox = CType(editedItem.FindControl("drpleavetype"), RadComboBox)
            Dim LeaveRequest_Fkey As Label = CType(editedItem.FindControl("lblid"), Label)







        End If

I need to be able to reference these values in the custom validator event as shown below:

Private Sub HoursPositiveValidator_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles HoursPositiveValidator.ServerValidate

'Create variable to hold instance of validation return array.     Dim ReturnArray = LeaveClass.CustomDateValidation(FirstGridDateTimePicker.selectedvalue, SecondGridDateTimePicker.selectedvalue)

If returnarray(0) = "False" then         args.isvalid = false     End If End Sub

Is it possible to reference these values outside of one of the radgrid events because a standard validation and custom validation will not fit my needs. Any help will be greatly appreciated.

Thanks,
Jonathan Adkins

Hello Jon,

I am not quite sure as to the reason you cannot use any standard or custom validator in ASP.NET, but the edited items can also be accessed outside RadGrid's ItemComand or UpdateCommand events. Your RadGrid's EditItems collection stores all items that are currently in edit mode. You can iterate over the collection and use FindControl() (if you are using FormTemplate editing) to access your custom editing controls.

Hi Jon,

You may loop through the Grid rows in edit mode and hence access the controls from the  EditFormTemplate as shown below.

VB:

    Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As ServerValidateEventArgs)
        For Each Item As GridDataItem In RadGrid1.EditItems
            Dim picker1 As RadDatePicker = DirectCast(Item.EditFormItem.FindControl("RadDatePicker1"), RadDatePicker)
            Dim selectedDate As DateTime = DirectCast(picker1.SelectedDate, DateTime)
        Next
    End Sub

Hi Jon,

In case you use auto-generated grid column editors and do not know the ID of your editor controls:

Protected Sub Button1_Click(ByVal source As Object, ByVal e As EventArgs) Handles Button1.Click
        For Each item As GridItem In RadGrid1.EditItems
            If TypeOf item Is GridDataItem Then
                Dim dataItem As GridDataItem = DirectCast(item, GridDataItem)
                Dim editor As GridTextBoxColumnEditor = DirectCast(dataItem.EditFormItem, GridEditFormItem).EditManager.GetColumnEditor("UserName")
                Results.Controls.Add(New LiteralControl(editor.Text + "<br />"))
            End If
        Next
    End Sub

The above code iterates over all data items in the edited items collection, gets their EditFormItems and finds the column editor for grid column with unique name UserName. After converting it to the editor of the appropriate type (GridTextBoxColumnEditor for GridBoundColumns), you can retrieve the editor's Text property.
