[Solved] Change Radbutton cssclass clientside

When using the radbutton (see markup below) I would like to know the controls method to change the cssclass...

I figured I would have access to a method like .set_cssClass... but I don't see that... Via the documentation..

What is provided is the get_cssClass...

Anyway, I know how to do this via straight javascript or jquery.. but is there a telerik way?

<telerik:RadButton ID="ImageButtonStatusLock" CssClass="UnLockIcon" runat="server" Text="Image Button" OnClientClicked="OnClientClicked" AutoPostBack="false" ButtonType="StandardButton">

<Image EnableImageButton="true" />

</telerik:RadButton>

I would like fire on clientevent OnFocus and OnBlur to change backgroundColor.

When focus gets on textbox one color and when focus leaves textbox another color.

How can I do that?

Connecting a Javascript function to a C# method

I am using Telerik AJAX UI
V2014.1.225.40.

I am a newbie to both Telerik and Visual 2012 but I am
learning fast.

I added a RadToolBar control to my WebPage and a RadPanelBar
on the left-hand side. I noticed that on
the RadPanelBar property list, there is a property called “Visible”. When this is set to false, the PanelBar
disappears. Very cool!

So next, I wanted to see if I could make the PanelBar appear
(RadPanelBar.Visible=true) when the user clicked on a RadToolBar item (a C#
method in my Default.aspx.cs called “RadToolBar1_ButtonClick”). So, I noticed that in the list of properties
for RadToolBar, there is a property called “OnClientButtonClicked”. When I put an “event name” on that property,
Telerik created a JAVA Script HTML function that was empty.

First, what do I put into that empty function.

Second, what do I modify inside my Default.aspx.cs program
that would connect that JAVA Script Function to the method with the code that
sets the Property RadToolBar.Visible to true.
I looked at the examples and could not found one that matched my needs.

How do I do that?

Find UserControl in RadGrid on EditCommand

I have a user control which I am using for Edits and Inserts. The usercontrol has properties on it that need to be set when rendered or when the editcommand is issued. I am trying to find the usercontrol in the RadGrid so that I can set its properties before it is shown in the edittemplate. The properties that need to be set change the user controls appearence when it is shown and the way it processes data, so the properties have to be set before data is bound....I have tried many events (the EditCommand follows) but the uc cannot be found and is allways Nothing/null.

Private Sub rg_EditCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles rg.EditCommand

Dim uc As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)

lbl_test.Text =

CType(uc, uc_Steps_Party).ID 'this is where the error occurs because uc == Nothing

End Sub

I have also tried:
EditCommand

ItemDataBound

ItemCreated

ItemCommand

Always a null exception refering tot he usercontrol.

The Telerick examples seem to only show finding the usercontrol (after) it has renedered like in the UpdateCommand or InsertCommand. I need to find the user control and set its properties before it gets to those events, when the usercontrol is first shown.

Cursor doesn't show in Chrome for empty RadEditor

We're experiencing this on our own site, but I also reproduced it in the Default Example for RadEditor. Steps to take:

Open the example.
Go to the HTML tab and delete ALL the content.
Go to the Preview tab. Preview content is blank, of course.
Go to the Design tab. Click anywhere in the editor. The cursor will not appear.
Type any letter and suddenly the cursor appears. Backspace to delete that letter (so the editor content is empty again) and the cursor remains.

correct event to override default value for SQLdatasource select param in radgrid

Hi Folks - Apologies in advance, this may not be the best place to post.

I have an ASP.NET 3.5 app. I have a page with a multi-select listbox, a button, a radgrid and a SQL datasource. The datasource has one param that looks sorta like this ...

<asp:ControlParameter Name="Param1" ControlID="lstParam1" PropertyName="SelectedValue" />

so, currently, without any extra code, only the first selected value from the listbox is passed to the sql datasource.

I have code to make a comma sep list of the multi selected values, and I have a sproc for list_to_table type functionality so thats not the problem.

Problem is that Im having a hard time finding the right event to use to override the default value of this param.

I can supply more markup/code if needed.

Any help is appreciated ... apologies agian if Im using the wrong forum.
