InsertCommand will not fire

I'm trying to manually insert a row into an SQL table through the RadGrid's insert row function. My problem is that the InsertCommand event will not fire. Here's some code:

<telerik:RadGrid ID="grdDesc" runat="server" AutoGenerateColumns="false">

<MasterTableView CommandItemDisplay="Top" EditMode="InPlace" DataKeyNames="Descrip"

InsertItemPageIndexAction="ShowItemOnCurrentPage" ShowHeader="false">

<Columns>

<telerik:GridEditCommandColumn ButtonType="PushButton" UniqueName="Edit">

</telerik:GridEditCommandColumn>

<telerik:GridBoundColumn DataField="Descrip" UniqueName="Descrip">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Scrolling UseStaticHeaders="true" AllowScroll="true" />

</ClientSettings>

</telerik:RadGrid>

<telerik:RadInputManager runat="server" ID="RadInputManager1" Enabled="true">

<telerik:TextBoxSetting BehaviorID="TextBoxSetting1">

</telerik:TextBoxSetting>

</telerik:RadInputManager>

Visual Basic code:

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

...

Dim ctxSql As LINQtoSQLDataContext = New LINQtoSQLDataContext()

If chkDesc.Checked = True Then

grdDesc.Visible = True

Dim descrips = From c In ctxSql.COMBOBOXes Where c.fieldname = "DESCRIP" Select New With {c.descrip}

grdDesc.DataSource = descrips

grdDesc.DataBind()

Else

grdDesc.Visible = False

End If

...

End Sub

Protected Sub grdDesc_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles grdDesc.ItemCreated

If TypeOf e.Item Is GridEditableItem AndAlso (e.Item.IsInEditMode) Then

Dim editableItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

Dim textBox = (DirectCast(editableItem.EditManager.GetColumnEditor("Descrip"), GridTextBoxColumnEditor)).TextBoxControl

textBox.ID = "TextBox1"

Dim inputSetting As InputSetting = RadInputManager1.GetSettingByBehaviorID("TextBoxSetting1")

inputSetting.TargetControls.Add(New TargetInput(textBox.UniqueID, True))

inputSetting.InitializeOnClient = True

inputSetting.Validation.IsRequired = True

End If

End Sub

Protected Sub grdDesc_InsertCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles grdDesc.InsertCommand

Dim ctxSql As LINQtoSQLDataContext = New LINQtoSQLDataContext()

Dim custFileID = ctxSql.CUSTFILEs.Where(Function(c) c.CUSTNO = cboCustNew.SelectedValue).Single.CUSTFILE

Dim newComboBox As COMBOBOX = New COMBOBOX()

newComboBox.custfile = custFileID

newComboBox.department = -1

newComboBox.fieldname = "DESCRIP"

newComboBox.descrip = ""

ctxSql.COMBOBOXes.InsertOnSubmit(newComboBox)

End Sub

I can tell you the ItemCreated event DOES fire and runs successfully. I just don't understand why the InsertCommand event doesn't fire. If anybody can tell me what I'm missing, it would be appreciated.

Thanks,
Patrick

Excel export: The file you are trying to open, '[filename]', is in a different format than specified by the file extension

Hello!

When I'm exporting to Excel (HTML or ExcelML) and when I'm opening exported file I'm getting this error/notification:

    
            "The file you are trying to open, '[filename]', is in a different
            format than specified by the file extension. Verify that the file is
            not corrupted and is from a trusted source before opening the file. Do
            you want to open the file now?"  (Yes | No | Help)

Is there any workaround (without changing registry/excel settings) for this to make excel not showing this question?

Thanks

EDIT: Ok. I've found solution for my problem here:

[Solved] Hiding the Expand in the grid

I have a hierarchical grid that I have been implementing security on.

What I have done is limit the user to see only data they are allowed to see. So in the databind I skip over it if the user does not have access to that level of detail. I would also like to remove the expand if they dont have access to the detailed info. Anyway to do that?

Hide/Show Certain RadGrid Context Menu Items

Hi there, I have a context menu showing when the radgrid is right clicked which displays options "email user", "email mass users", "email users who have finished".

I have a radgrid which is populated with data which shows whether users have started or not started their courses. I have a column called "HasStarted" which displays false and true depending on whether or not they have started. When I right click on a row which has "HasStarted" as false I want "email user", "email mass users" to appear in the context menu and when I click on a row which has "HasStarted" as true I want "email users who have finished" to only appear in the context menu. The context menu works and the items run the correct cases just not sure how to hide and show certain items depending on the item clicked on. Any help will be appreciated thanks.

Strange behaviour on column resize

hi,
I'm making some test on your ajax grid and I've found it great but I've found an annoying problem regarding column resize.

This problem is present in your demo as well so you can easly verify it.
Go to http://demos.telerik.com/aspnet-ajax/grid/examples/client/resizing/defaultcs.aspx

Try to resize column by clicking between "Address" and "Postal Code", all columns width are affected by this action and their width change.
Please let me know if there is a way to work around this behaviour.

thanks a lot for your help

Custom Filtering for Template Column

Hi,

I have a Rad Grid control that is bound to a data source which has objects in it.
I use the object properties to feed the template in the template columns.

Please show me how can I implement custom filtering, which events do I need to handle ?
I need a way from which I can use the object and then decided if this row should be filtered or not.
The out of the box filtering is not going to work for my case.

I cant find any examples, please help.

Thanks
Karan

form within form - Ajax?

I am not sure if it is an Ajax-specific problem, or, just a Rad script issue... but, if I have a form inside the default page form, Telerik controls do not seem to work (it throws an error). If I remove this sub form, things work.

Here is sample code:

<%@ Page Language="VB" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="current_sswdc._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script language="JavaScript" type="text/javascript">

<!--

window.status = "This is a test of Telerik with inside forms to PayPal.";

}

// end -->

</script>

<script type="text/javascript">

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-26024342-1']);

_gaq.push(['_trackPageview']);

(function () {

ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);

Here is the code-behind:

Imports Telerik.Web.UI

Partial Class _Default

Inherits System.Web.UI.Page

Protected Sub rdpDateToView_SelectedDateChanged(sender As Object, e As Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs) Handles rdpDateToView.SelectedDateChanged

lblDatePicked.Text = e.NewDate.ToString

End Sub

End Class

So - the PayPal forms are what break this. I cannot find a way around having the PayPal forms - somehow, I have to be able to use forms inside the main page form. Does anyone have some insight as to how I can resolve this conflict?

Thanks.
