I have a RadGrid (Grid1) with Master table edit mode = popup. I have the following code in the commandItemTemplate. The popup is a user control.The popup has some textboxes and another Grid (Grid2).
<CommandItemTemplate> 
                                    <table width="100%" border="0" cellspacing="0" cellpadding="0"
                                        <tr style="height: 20px"
                                            <td style="width: 100%; color: #074768" align="right"
                                                <asp:LinkButton ID="lnkBtnAddLocation" runat="server" CommandName="InitInsert" Style="font-weight: bold;
                                                    padding-right: 2px; color: #074768;"
                                                    <asp:ImageButton ID="imgbtn_AddLocation" runat="server" SkinID="AddRecord" CommandName="InitInsert" /> 
                                                    Add Location 
                                                </asp:LinkButton> 
                                            </td> 
                                        </tr> 
                                    </table> 
</CommandItemTemplate> 

If I click on "Add Location" it opens a popup. I enter some data and when I click on save, It closes the popup and inserts the data in the RadGrid. But I want the popup to remain open. This is because I want to have a Save button for saving the textboxes data to Grid1 and a OK button for saving the selections in the Grid2 to the Grid1.

Is it possible to keep the popup open after Inserting data into Grid1?

Hello Pradeep,

Here is the code for keeping the pop-insert form:
protected void Page_Load(object sender, EventArgs e)
{
    RadGrid1.ItemInserted += new GridInsertedEventHandler(RadGrid1_ItemInserted);
}
protected void RadGrid1_ItemInserted(object source, GridInsertedEventArgs e)
{
    e.KeepInInsertMode = true;
}

Hope it helps.

All the best,

Hello,

I am trying to do the same thing but when I put that code in the Page_Load, I get two errors highlighted in the environment.

1. 'Public Event ItemInserted(source As Object, e As Telerik.Web.UI.GridInsertedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

2. Delegate 'Telerik.Web.UI.GridInsertedEventHandler' requires and 'AddressOf' expression or lambda expression as the only argument to its constructor.

Thanks,

Steve

Hello Stephen,

My code snippet is in C# and you evidently are programming in VB. Here is the code in VB:

Protected Sub Page_Load(sender As Object, e As EventArgs)
    RadGrid1.ItemInserted += New GridInsertedEventHandler(AddressOf RadGrid1_ItemInserted)
End Sub
Protected Sub RadGrid1_ItemInserted(source As Object, e As GridInsertedEventArgs)
    e.KeepInInsertMode = True
End Sub

Hope it helps.

Hello,

I had converted the code to VB first...but the code converter didn't give me the 'AddressOf ' so I added that in and it solved the second error.  But I am still getting the first error:

'Public Event ItemInserted(source As Object, e As Telerik.Web.UI.GridInsertedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

How do I use the RaiseEvent statement with this as it seems it doesn't like me calling it as is?

thanks,

Steve

Hi Stephen,

The error states that somewhere in your code you have a statement such as the one below:

ItemInserted(....)

where as you cannot call event delegates in this way as they will automatically triggered by the framework. Could you paste you complete code-behind?

Hello,

The only place that appears is the two places you designated:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim cRegistration As New CRegistration
    hidRegistrationID.Value = DirectCast(Me.Parent.NamingContainer, GridNestedViewItem).ParentItem.GetDataKeyValue("RegistrationID").ToString()
    cRegistration.LoadRegistrationTypeID(HttpContext.Current.Session("UserID").ToString, hidRegistrationID.Value)
    hidRegistrationTypeID.Value = cRegistration.RegistrationTypeID.ToString
    gvOrders.ItemInserted += New GridInsertedEventHandler(AddressOf gvOrders_ItemInserted)
End Sub

Protected Sub gvOrders_ItemInserted(ByVal source As Object, ByVal e As GridInsertedEventArgs)
    e.KeepInInsertMode = True
End Sub

Thanks,

Steve

Hi Stephen,

The code seems all right. Still expecting the complete code-behind. You can also add the aspx. Thanks for that.

Hello Pradeep,

Sorry for having sent you the wrong syntax for the addition of the event handler. The correct one in VB.NET is:
AddHandler gvOrders.ItemInserted, AddressOf gvOrders_ItemInserted

Hope this will finally fix the exception at hand.

Hello again,

Thank you.  That code cleared up my exception...but the gvOrders_ItemInserted method is still never being called so it does not remain in edit mode.  I tried adding the OnItemInserted="gvOrders_ItemInserted" to the grid and that didn't help either.

When would it reach the ItemInserted method?  When it the item considered inserted?  Is it after the InsertCommand method is executed?  I am getting that far.  It executes the InsertCommand method but never hits the ItemInserted method.

Thanks,

Steve

Hi Stephen,

The ItemInserted event is thrown only if the item is inserted. It happens always after the InsertCommand : the InsertCommand event marks the beginning of the operation and the ItemInserted one - its successful end. Please, check if your item is inserted all right into the underlying data store - I suspect this must be the reason.

Hello,

Well that sort of explains the issue I am having.  Here is the code of my InsertCommand:

Private Sub gvOrders_InsertCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles gvOrders.InsertCommand
    If e.CommandName = RadGrid.PerformInsertCommandName Then
        If CustomValidation(e) Then
            Dim cRegistration As New CRegistration
            Dim iRet As Integer
            Dim bRet As Boolean = False
            Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)
            iRet = cRegistration.AddOrder(HttpContext.Current.Session("UserID").ToString, hidRegistrationID.Value, HttpContext.Current.Session("AdminWorkshopID").ToString)
            Dim rblRequiredRegistration As RadioButtonList = CType(editedItem.FindControl("rblRequiredRegistration"), RadioButtonList)
            Dim txtPrice As TextBox = CType(editedItem.FindControl("txtPrice"), TextBox)
            Dim gvAddOns As GridView = CType(editedItem.FindControl("gvAddOns"), GridView)
            If iRet > 0 Then
                bRet = cRegistration.AddUpOrderItemOverride(HttpContext.Current.Session("UserID").ToString, _
                                                            iRet.ToString, _
                                                            rblRequiredRegistration.SelectedValue, _
                                                            "1", _
                                                            txtPrice.Text)
                If bRet Then
                    For Each row As GridViewRow In gvAddOns.Rows
                        Dim chkItem As CheckBox = CType(row.FindControl("chkItem"), CheckBox)
                        Dim txtQuantity As TextBox = CType(row.FindControl("txtQuantity"), TextBox)
                        Dim txtAddOnPrice As TextBox = CType(row.FindControl("txtPrice"), TextBox)
                        If chkItem IsNot Nothing AndAlso chkItem.Checked Then
                            bRet = cRegistration.AddUpOrderItemOverride(HttpContext.Current.Session("UserID").ToString, _
                                                                            iRet.ToString, _
                                                                            gvAddOns.DataKeys(row.RowIndex).Value.ToString, _
                                                                            txtQuantity.Text, _
                                                                            txtAddOnPrice.Text)
                            If Not bRet Then
                                Exit For
                            End If
                        End If
                    Next
                    If bRet Then
                        gvOrders.DataBind()
                    Else
                        gvOrders.Controls.Add(New LiteralControl("<strong>Save add-ons failed!</strong>"))
                    End If
                Else
                    gvOrders.Controls.Add(New LiteralControl("<strong>Save registration failed!</strong>"))
                End If
            Else
                gvOrders.Controls.Add(New LiteralControl("<strong>Add Order failed!</strong>"))
            End If
        End If
    End If
End Sub

Since I am using custom code to perform the insert, do I need to return something to show that the item was successfully inserted because the ItemInserted is never fired, even when the item was successfully inserted.

But what I am trying to do actually is keep it in edit mode when it fails on my CustomValidation method that is called within the InsertCommand shown above.

thanks,

Steve

Hi Stephen,

The ItemInserted event is designed to work only with DataSource controls when those are connected to the grid. In other words, it is just a convenience that lets the developer know whether the DataSource control has performed the CRUD operation successfully or not.

However, when you are performing the CRUD operations manually as in your case you do not have a need for the ItemInserted event as you directly know whether you have inserted the new item into the collection or not. That is, the moment you call cRegistration.AddUpOrderItemOverride or cRegistration.AddOrder  you know that the item has been inserted. If you are afraid that some exception might be thrown by those custom methods, you might surround their call location with a try and catch block. If the catch block is hit, then you will know that something has gone wrong and can take action accordingly.

Hello,

Ok that sounds like a plan, my only question now is when I am catching the exception of my custom AddOrder method within the grid InsertCommand method, how do I do the KeepInInsertMode so my edit form doesn't close?  The KeepInInsertMode is not a member of GridCommandEventArgs.

thanks,

Steve

Hello Stephen,

You need to use to set e.Canceled = true as this will effectively keep the insert form open and prevent the grid from rebinding.

Hope it helps.

All the best,

So cool. Exactly what I needed. It took me so long to fid it that I add it here for the record ;)

"telerik Asp.net radgrid popup stay open after exception" :

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)
{
    try
    {
        GridEditableItem item = e.Item as GridEditableItem;
        Hashtable values = new Hashtable();
        item.ExtractValues(values);
        Session session = new Session();
        item.UpdateValues(session);
        DbContext.AddToSessions(session);
 
        //submit chanages to Db
        DbContext.SaveChanges();
    }
    catch (System.Exception)
    {
        e.Canceled = true; //keep the popup open
        ShowErrorMessage();
    }
}
