Change text of RadButton on client-side with JavaScript

Hi! Could someone provide me an example of how to change the text of a RadButton using JavaScript? Basically when a user clicks the 'submit' button I want to display an alert message, disable the button, and change the text to say 'Submitting'. I've got the alert message working, but the button text doesn't appear to change nor is it disable.

Here's the lines of code for the javascript...

<telerik:RadCodeBlock ID="rcb1" runat="server">

<script type="text/javascript">

function DisableSubmitBtn() {

alert("Submitting Review, please do not click submit more than once");

document.getElementById('<% =btnItemSubmitE.ClientId %>').value = 'Submitting';

}

</script>

</telerik:RadCodeBlock>

Here's the button code...

<telerik:RadButton ID="btnItemSubmitE" runat="server" Skin="Sunset" Text="Submit"

Width="45%" ValidationGroup="Review" OnClientClicked="DisableSubmitBtn" >

<Icon PrimaryIconCssClass="rbOk" PrimaryIconLeft="4" PrimaryIconTop="4" />

</telerik:RadButton>

There are validation controls on the page and a RadAjaxManager is being used.

Thank you!

How to run a javascript function when RadGrid control is loaded?

I have a javascript function as below:

 function run() {
        alert('run');
    }

I have a RadGrid control which is updated using RadAjaxManager. How could I run that javascript when the RadGrid is updated? I had hoped to see a OnClientLoad event on this control but there is none. Any help?

RadGrid Change row background color

Hi,
In each row of my RadGrid I have a CheckBox as shown below.

<telerik:GridTemplateColumn HeaderText="Is Critical?" HeaderButtonType="TextButton" UniqueName="critical">

<ItemTemplate

<asp:CheckBox ID="chkCritical" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

When the user checks the CheckBox system makes an ajax call from clientside and updates the database. This part is working fine.
I want change the row background color on check/uncheck of the CheckBox on clientside. Could not find a method to set background color on DataItem. Please help.

Standalone imageManager globalization

Hi,

I have a standalone ImageManger on the page which is not taking the correct globalization settings from the thread.

I have

Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE")
Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE")

In Code behind but it is falling back to the default culture from web.config.

How can I set the dialog language correctly?

Tooltipify Image in Template Column

Hi, I have a RadGrid that gets bound with template columns that contain a single image (it's an indicator light). Here's the code for the template column:

                    Public Class GridImageItemColumn         
               Inherits GridTemplateColumn         
                     
               Public Class GridImageItemTemplate         
                  Implements ITemplate         
                           
                  Public column As GridImageItemColumn = Nothing         
                      
                  Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn         
                     Dim image as New Image()         
                     image.ID = Me.column.UniqueName         
                     container.Controls.Add(image)         
                     AddHandler image.DataBinding, AdressOf image_DataBinding         
                  End Sub         
                     
                  Private Sub image_DataBinding(ByVal sender As Object, ByVal e As EventArgs)         
                     Dim dataItem As GridDataItem = CType(CType(sender, Control).NamingContainer, GridDataItem)         
                     If dataItem IsNot Nothing Then         
                     Dim image As Image = CType(sender, Image)         
                     image.CssClass = "t_img"         
                     Dim value As String = DataBinder.Eval(dataItem.DataItem, Me.column.DataField).ToString()         
                     If Not String.IsNullOrEmpty(value) Then         
                        image.ImageUrl = "~/images/" & value & ".png"         
                     End If         
                  End Sub         
               End Class         
                     
               Public Sub New()         
                  Dim template As New GridImageItemTemplate()         
                  template.column = Me         
                  Me.ItemTemplate = template         
               End Sub         

What I'm wondering is, how can I dynamically tooltipify these indicator lights? I've tried to do it via how the example states:

                    Me.RadToolTipManager1.TargetControls.Add(target.ClientID, (TryCast(e.Item, GridDataItem)).GetDataKeyValue("ID").ToString(), True)         

but .. that doesn't work since I have no way to find the target Image control, since the name isn't static (it isn't static, because there are n number of these columns).

Any clues?
