[Solved] Launching PopUp EditForm from Custom Command

[Bill Steamshovel]

I bind a list of business objects to a radgrad and I have a different usercontrol for the adding and editing of the object. This works fine. Now I want to add a custom command (EndLife), so I thought I would simply add it to the ItemCommand handler to perform different logic on it. This is code I have below:

Protected Sub MilkCrateListView_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles MilkCrateListView.ItemCommand
        If (e.CommandName = Telerik.Web.UI.RadGrid.InitInsertCommandName) Then
            e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/AddMilkCrate.ascx"
            e.Canceled = True
            rgParts.EditIndexes.Clear()
            e.Item.OwnerTableView.InsertItem()
        ElseIf (e.CommandName = Telerik.Web.UI.RadGrid.EditCommandName) Then
            e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/EditMilkCrate.ascx"
            e.Item.OwnerTableView.IsItemInserted = False
        ElseIf (e.CommandName = MilkCrateView.EndLifeCommandName) Then
            e.Item.Edit = True
            e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/EndLifeMilkCrate.ascx"
            e.Item.OwnerTableView.IsItemInserted = False
        End If
    End Sub

The first time I click EndLife, the line item within the RadGrid is highlighted and put into EditMode, but the PopUp doesn't launched until I click EndLife. This is an issue itself, but because of this, the datagrid doesn't rebind inbetween calls, meaning the UserControl receives a null DataItem.

How can I get the PopUp to fire immediately? Would I fire an EditCommand from within the ItemCommand handler? If so, can someone give me an example of doing this?  

If not, how would I go about acheiving the functionality desired?

EDIT: Instead of using a Custom Command Name, I reused the CommandName Edit and added a CommandArgument 

ASP.NET

<telerik:GridButtonColumn ButtonType="LinkButton" CommandName="Edit" CommandArgument="Edit" HeaderText="Edit" Text="Edit" ></telerik:GridButtonColumn>
<telerik:GridButtonColumn ButtonType="LinkButton" CommandName="Edit" CommandArgument="Remove" HeaderText="Remove" Text="Remove"></telerik:GridButtonColumn>

VB.NET

Protected Sub MilkCrateListView_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles MilkCrateListView.ItemCommand
   If (e.CommandName = Telerik.Web.UI.RadGrid.InitInsertCommandName) Then
      e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/AddMilkCrate.ascx"
      e.Canceled = True
      rgParts.EditIndexes.Clear()
      e.Item.OwnerTableView.InsertItem()
   ElseIf (e.CommandName = Telerik.Web.UI.RadGrid.EditCommandName) Then
      e.Item.OwnerTableView.IsItemInserted = False
      If (e.CommandArgument = MilkCrateView.EndLife) Then
         e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/EndLifeMilkCrate.ascx"
      Else
         e.Item.OwnerTableView.EditFormSettings.UserControlName = "~/uc/EditMilkCrate.ascx"
      End If
   End If
End Sub

Hi Bill,

To achieve the described functionality I recommend you to use the FireCommandEvent(eventName, eventArgs) method and call it for the particular item.

For additional information you may take a look at the How to fire command events from code help topic.
