Hi guys, I am having trouble doing something I thought would be simple.
The scenario:
1. A combobox on a page with autopostback set to true and a sub in the codebehind that I want to fire whenever the combobox changes.
Protected Sub cmbxHerbicide_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles cmbxHerbicide.SelectedIndexChanged
Dim con As New S
.............
..............
End Sub
2. On page load I grab a querystring and use it to change the combobox.
cmbxHerbicide.SelectedValue = Request.QueryString("ActiveID")
Ok, when I run this the combobox is changed as expected but the sub does not fire.
So I thought I would try:
cmbxHerbicide.SelectedValue = Request.QueryString("ActiveID")
cmbxHerbicide_SelectedIndexChanged(e, e)
This produces an error.
Unable to cast object of type 'System.EventArgs' to type 'Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs'
How do I get around this?
I had expected that if I had AutoPostback set to true, and I changed the selection then the SelectedIndexChanged would fire.
What event args do I need to send?
Cheers
Ian
PS. The sub fires fine if I manually change the combobox. The reason I am doing it in this way is that sometimes I want to run the code from a value pulled from a querystring, but once the user is on the page they can then go and select other values. A worst case scenario is that I duplicate lots of code, I don't want to do that, the simple solution is to change the selection and call the sub.

I am using an EditCommandColumn to Edit/Update/Insert records but when I use custom images instead of the default text, there is an unnecessary line break between the Update/Cancel images in Edit Mode as well as the Insert/Cancel images in Insert Mode. If I leave the default they display side by side. I am not specifying a header or item width and even if I do, I get the same results. The column widths are adjusting as necessary when I am using text. I can't seem to find any properties in the column to set any sort of image display layout.
Any ideas?
<telerik:GridEditCommandColumn ButtonType="ImageButton" EditImageUrl="images/edit.gif" UpdateImageUrl="images/update.gif" InsertImageUrl="images/update.gif" CancelImageUrl="images/delete.gif"></telerik:GridEditCommandColumn>Any ideas?

Hello,
I am finding the behavior of the HideOnBlur property a little difficult to understand. If I add a RadMaskedTextBox to a page, apply a mask, and set the HideOnBlur property to true it works as I would expect. When the control doesn't have focus the prompting characters and mask characters are hidden. However, if I fill the .Text property with a value programatically, say in page load, then everything including the value I supplied is hidden until focus is given to the control and focus is switched off of the control and the onblur event is fired.
This results in a page loading and data that was supplied to the control doesn't show up. Then you click inside the control and if you remove focus or start typing the supplied text appears. Should I be supplying text to the RadMaskedTextBox in a different manner then using the .Text property of the control?
Thank you,
Jeremy
EDIT: Sorry... this should be in the ASP.NET AJAX > General Discussions... I didn't realize I was in the sub forum.

Hi,
I have a load-on-demand RadTabStrip inside a Window that is set to a fixed width and height (the window, that is). My problem is that the last PageView attached to the RadMultiPage that is referenced by the RadTabStrip is a summary page that may overflow to the bottom of the RadWindow based on what the user selects under previous tabs, but the RadWindow does not display a scroll bar to reflect this. I can only view the content that is at the bottom of the RadWindow by clicking on my mouse's scroll wheel. I have tried to fix this by setting the height of that last RadPageView both client and server-side, and I can tell that it is in fact set to that height - but still no scroll bar. Is there a way I can accomplish this?
Thank you.

Hi Telerik team,
I have a number of columns in my radgrid and when i try to move a particular column to another position, it actually swaps the columns instead of just placing the column of my choice in the place that i desire. Is there a way i can avoid that swap. I hope i made sense.
Thanks,
Chandra

I am using RadEditor with the MS Word spelling provider. I used the instructions at http://www.telerik.com/community/forums/aspnet-ajax/spell/enabling-ms-word-spell-checking.aspx to get it working.
It is spell-checking, but it does not seem to be using the en-US.tdf file in my ~/App_Data/RadSpell/ directory. The special words (medical terms) I added to the dictionary are still flagged as misspellings. Also, I can rename the file, and it still does spell-checking.
Here is my markup:

Here is my markup:
<telerik:RadEditor runat="server" ID="edNotes" Height="200" Width="98%" ContentAreaMode="Iframe" EditModes="Design" EnableResize="true" ToolsFile="~/App_Data/ToolsFile.xml" SpellCheckSettings-CustomDictionarySuffix="Custom" SpellCheckSettings-DictionaryLanguage="en-US" SpellCheckSettings-DictionaryPath="~/App_Data/RadSpell/" SpellCheckSettings-SpellCheckProvider="MicrosoftWordProvider" SpellCheckSettings-AllowAddCustom="true" /> I have the following in my Page_Load routine:edNotes.SpellCheckSettings.SpellCheckProviderTypeName = typeof(Telerik.Web.UI.WordSpellCheckProvider).AssemblyQualifiedName;Is the MS Word provider supposed to use en-US.tdf, or does it use the dictionary that Word/Office uses? I tested that and it does not seem to be using the Word dictionary. Also, I need to get the Custom dictionary file working as well. Please comment on that as well. Thanks, - Tim

When using radeditor a 404 error is displayed in the popup for adding an image or creating a link.
The error only happens on the server and works fine on localhost.
Also, when the popup is displayed it appears behind the rad menu.

Hello everyone,
I have a problem with my Headercontextmenu, can somebody please help me?
This is my situation:
I have a hierarchical RadGrid with a detailtable. On my RadGrid I enabled a headercontextmenu with an additional control to add a new item in my RadGrid.
So I want a headercontextmenu on the detailtable; now when I click on my "add new record" - button in the headercontextmenu of the detailtable it adds a new item in my mastertable.
How can I check on which level the button was clicked?
Or can I add an additional headercontextmenu only for my detailtable?
Thanks in advance,
regards esmyy
