There are, say 2 items in a combobox. How do I set first item (visible for the user with icon and text) and prohibit selecting another item? So combobox should not expand and be "Read-only".

Hi Guys!

I'm beginner in .NET development. But I've learned how to save time with this technology. I'm very impressed with the power of Telerik too.
Well, here is my trouble for now:

I've a grid that show many columns. I need show all the content columns without wrap lines with horizontal scrool activated, like this.
But when I'll configure a grouped column, the horizontal scrool bar disappears and the column content are cropped, like can see here.

Here the grouping code:
         

<GroupByExpressions>

  <telerik:GridGroupByExpression>

    <SelectFields>

      <telerik:GridGroupByField FieldAlias="Evento" FieldName="Evento" FormatString="{0:D}" HeaderValueSeparator=": ">
        </telerik:GridGroupByField>

    </SelectFields>

     <GroupByFields>

      <telerik:GridGroupByField FieldName="EVENTO" SortOrder="Ascending"></telerik:GridGroupByField>

     </GroupByFields>

   </telerik:GridGroupByExpression>
</GroupByExpressions>

Can anybody help me?

Hi,

I am trying to add checkboxcolumn to support selection of rows in the RadGrid Control

I have tried both client and server side approaches but have issues with both the approaches. I have ran throught the samples provided
 the server side approach seems to work fine.

My Requirement is to be able to  capture the selected rows on the server side apart from selecting and deselecting the rows
on the grid. let me know the suggested apprach.

I have tried the Server side approach but the Toggle events are getting fired in wrong order.
For example if I select the Checkbox in the HeaderRow the ToggleSelectedState gets fired on first check but on unchecking the
same CheckBox ToggleRowSelection gets fired henceforth whihc is not what the expected behaviour should be. Please see attached file for the radgrid aspx code.

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
<HeaderTemplate>
<asp:CheckBox ID="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True" runat="server"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" OnCheckedChanged="ToggleRowSelection" AutoPostBack="True"
runat="server">


If I had to use the Client side approach how will I be able to capture the selected rows on the server side. If you can provide us some sample as attahced project It would be of great help!

<telerik:GridClientSelectColumn UniqueName="grdClinetSelectCol"></telerik:GridClientSelectColumn>

</asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>

Hi,

We have a LoadOnDemand ComboBox (2008.3.1114.35) with Header and ItemTemplates. When a user searches a text comprised of multiple words with space between words, spaces are encoded to %20 in text value of RadComboBoxItemsRequestedEventArgs object.  Furthermore, this generates other ItemRequested events, only this time '%' is encoded as '%25.' and continues for some time. (i.e. sample text, generates event for sample%20text, then sample%2520text, then sample%252520text etc.)

Code snippet of ComboBox is included below, .cs file is not included as it only contains comparison of text to empty string.

This occurs only sometimes, sometimes spaces are not encoded.  Are the users supposed to handle encoded chars separately or is this a bug ?

Thanks in advance,
Oner

Hello,

We are getting an intermitent java script error in our SharePoint custom ASP.NET page. (FYI, the telerik controls are showed into page via web parts which intern calls .NET user control)

Java script error details:

Message: 'type' is null or not an object

We make use of lastest Telerik.Web.UI and Telerik.Web.UI.Skins dlls version 2012.1.411.35.

Below are the list of web.config changes made for Telerik usage,
1) SafeControl
 
2) Page tag prefix

3) web.server handlers

The page works fine most of the time; but at times it throws above specified java script error and dont work anymore until another page refresh.

I couldn't even debug this error as this is very unstable error.  
May I know what may be the issue?

Your reply is much appreciated.

Thanks,

Hi,

I need to implement the recursive selection at this way:
1. Select all parents when the at least one child item was selected.
2. Select all childs when the parent was selected.

When i use "AllowRecursiveSelection=true" the 1st part of the task does not work for me (when deselect one of the child - parent deselects too). If AllowRecursiveSelection is true then "OnItemSelected" and "OnItemDeselected" client events does not fire...
In other way at client side "get_childItems()" return null for the node not expanded before select and "ExpandCollapse" command fires after "OnItemSelected" and "OnItemDeselected"...

I have no idea how to implement this task. Can anybody show the right way to complete this?

Thx.

Greetings,

I have a problem with recursive selection. Treelist selects recursively whole branch of selected node (all its ancestors and descendants). This behavior is pretty "unconfortable" for me. If my nodes are folders and files and I select a subfolder and I want to delete it with it contents for example then I cerainly don't want to delete its parent folder (or any of its ancestors) so I would like to ask if there is any way how to make treelist to recursively select only descendant nodes of selected item.

Thanks in advance

I have the following JavaScript code that creates a really simple JSON object...


This generates the following JSON string after running the object through the stringify method...

{"MyID":1,"MyItem":"This is the first item"}

This is valid JSON according to JSONLint.com.
Calling the .ajaxRequest() method results in Sys.WebForms.PageRequestManagerServerErrorException - "Specified cast is not valid"

It's not even getting to my RadAjaxManager1_AjaxRequest() event handler where I have a breakpoint set to inspect the value of e.argument.

What's wrong here?

I'm using version 2010.3.1317.35 of the Telerik controls.

I have an usercontrol that has a RadTabStrip control. This usercontrol is loaded in SharePoint 2007. The problem is that the Tabclick event is working for IE, Chrome, and Firefox but not for Safari.

I have a Breakpoint in the RadTabStrip1_TabClick event and I found out that code never is running.

I need your help!!
