Using different WebUserControls as custom edit form

 

Requirements
RadGrid for ASP .NET version	3.1.1 and later
.NET version	1.x
Visual Studio version	2002 and later
Programming language	VB.NET
Browser support	all supported by RadGrid for ASP .NET

 
Actually you have one and the same user control but with distinctive set of controls inside it. This project presents how to display file upload edit form when clicking the Upload file link button in an arbitrary grid row:

1. check whether e.CommandName is the name you specified for your GridButtonColumn
2. if so, switch the item in edit mode and rebind the grid (saving indicator in the Session for changing the edit form state)
3. wire the ItemCreated event to verify that the item is in edit mode and the Session flag is raised
4. clear the Controls collection of the EditFormCell for the GridEditFormItem
5. add HtmlInputFile control and upload button to the Controls collection of the EditFormCell for the GridEditFormItem

Note that the demo does not hold real update/file upload. If this is needed, you should include this functionality by writing custom code according to your requirements.

 

Do you have this sample in vs2005 and .net 2.0?

Hello Reggie,

Actually the core of this example is in these two methods:

Private Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid1.ItemCommand

If (e.CommandName = RadGrid.EditCommandName) Then
    Session("changeEditForm") = Nothing
End If

If (e.CommandName = "UploadFile" AndAlso TypeOf e.Item Is GridDataItem) Then
    e.Item.Edit = True
    Session("changeEditForm") = True
    RadGrid1.Rebind()
End If

If (e.CommandName = "Close") Then
    RadGrid1.EditIndexes.Clear()
    RadGrid1.Rebind()
End If

End Sub

 

Private Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles RadGrid1.ItemCreated

If (TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode) Then
    If (Not Session("changeEditForm") Is Nothing) Then

        Dim formItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
        formItem.EditFormCell.Controls.Clear()
        formItem.EditFormCell.Controls.Add(New System.Web.UI.HtmlControls.HtmlInputFile)    
        formItem.EditFormCell.Controls.Add(New LiteralControl("<br/>"))

        Dim uploadButton As Button = New Button

        uploadButton.Text = "Upload file"

        uploadButton.CommandName = "Upload"

        formItem.EditFormCell.Controls.Add(uploadButton)

        Dim closeButton As Button = New Button

        closeButton.Text = "Close"

        closeButton.CommandName = "Close"

        formItem.EditFormCell.Controls.Add(closeButton)

    End If

End If

End Sub

and you can easily use them in VS.NET 2005.

Hi Vlad
Thanks for the Heads Up!  What I am trying to do is use a grid as a data entry form that will allow a user to update 1 record. (No insert or delete required)  Do you have any other articles that will help me to understand how to do this.  Thanks

Hello Reggie,

We believe that the following topics from the grid online documentation can help you understand the specifics of the edit/update mechanism of r.a.d.grid:

Hi folks,

Here is the C# version of this example (under .NET 1.x framework) which has been kindly provided by Mostafa Anoosheh. Feel free to use that version in case this is the programming language you choose.

And happy coding :)
 
Best,
