In page load I want to reduce grid width by 250px.
I tried:

 

 

cnt = Convert.ToInt32(RadGrid1.Width) - 250

 

 

 

RadGrid1.Width = System.Web.UI.WebControls.Unit.Pixel(cnt)

but it did not work.

How can I do it?

 

Below is the scenario that I am not able to solve.
1. Master/Content Page setup.
2. Content Page has the RadAjaxManager object and a web user control (lets call it ucMaster)
3. ucMaster contains 3 other user controls, uc1, uc2 and uc3.  uc2 and uc3 are displayed based on a selection in ucMaster.  Both are loaded but the .Visible property is used to hide one or the other control.
4. uc1 has the RadAjaxManagerProxy1 and uses a radWindow dialog to get values and update the panel via ajaxrequest.  (Works fine)
5. uc3 has the RadAjaxManagerProxy2, and uses a radWindow dialog to get values and update the panel via ajaxrequest.  The "UpdatedControls" section uses the radAjaxManagerProxy2 as the "AjaxControlID" so that the panel is updated when the radWindow dialog is closed. (Does Not Work).

If I include the AJAX Setting in the ascx page under the RadAjaxManagerProxy AjaxSettings section, I get an error when the RadAjaxManagerProxy1 invokes an update for user control uc1.  The error is: "Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00xxxxx_grvContactsPanel'.  If it is being updated dynamically then it must be inside another UpdatePanel."

If uc3 is visible, the error does not come up.

I removed the "UpdatedControls" section from the radAjaxManagerProxy2.AjaxSetting section and add the control on the server-side in the page "PreRender" event.  The code runs, but the panel does not get updated.  If I move the server-side code to the "ajaxRequest" event handler I get the same error as before.

Any help with this will be greatly appreciated!

Thank you.

Hello,

See the attached image.  As soon as I click into the subject, it displays the error message, and even when I type, it still shows over top.  How do I fix this?  What is causing it, and is there a setting to turn it off?

Thanks.

Hi,
       Telerik has done a great job to minimise the developement time.
       I am using the telerik controls extensively.

      I am using the RadListBox control and it's 'AllowReorder' property to move the items of RadListBox up and down.
      Now, i want that items of two listboxes can move Up using single UP button and Signle down button for two Radlistboxes.
      Can i do that.

     In addition to that i need to edit the item (option) of one of my RadListBoxes on doubleclick on that item, can i do that ?

Please reply

Hello,

I have a page with many combo boxes hooked up to a web service.  Occasionally, 3 or so of the combos fail with a 403 forbidden response from the server.

Any idea why this happens?  I cannot figure it out.

Thanks.

For some reason my cursor disappears when I switch from html to Design view. This can be seen on this video (http://www.screencast.com/users/jpchatt/folders/Jing/media/75ce0779-718f-462a-aec8-4d17ec538224). This does not seem to happen in IE however, It only happens in FF.

The second firefox Inconsistency  is that the increase and decrease indent button does not function consistently. The decrease indent button intermittently breaks formatting for adjacent rows as well as the selected row. this can be seen in the following video (http://www.screencast.com/users/jpchatt/folders/Jing/media/9157a318-55a4-43df-9939-c3c668027d02). not sure why this doesnt happen in IE or why it only happens intermittently but it certainly seemed to be a bug.

Has anyone run into similar issues and know how to fix this?

Hi,
I am using the RadTabStrip control in my project. Here I am creating the tabs and adding the controls in to the tabs dynamically. But sometime when I switch between the tabs following java script error occurs.

Error Message: this.get_element().style is null or not an object.

After occurring this error switching between the tabs stops working. I am creating the rad tab strip in the following way.

<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
    <ContentTemplate>
    <telerik:RadAjaxPanel runat="server" ID="pnlRAD">       
            <asp:Panel CssClass="productmainGrid" ID="tsDiv" runat="server">       
                    <telerik:RadTabStrip  ID="RadTabStrip1" OnTabClick="RadTabStrip1_TabClick"
                                    runat="server" MultiPageID="RadMultiPage1" OnClientLoad="OnClientLoad"  EnableEmbeddedSkins="false" Skin="RadSkin" >
                    </telerik:RadTabStrip>

                    <telerik:RadMultiPage  ID="RadMultiPage1" runat="server"  OnPageViewCreated="RadMultiPage1_PageViewCreated">
                    </telerik:RadMultiPage>
        </asp:Panel>
    </telerik:RadAjaxPanel>        
    </ContentTemplate>
    </asp:UpdatePanel>

Please suggest me the possible solution for this error.

Thanks,

Hi.  I've a small problem with adding and removing nodes on a treeview on the client and then persisting the changes on a postback, using the ClientChanges property.  For the most part, it works as expected, I can Insert, Edit and Remove nodes and process the changes on the server.  However, the issue arises if I Insert a node, then Remove it and then try to save the changes.

In the ClientChanges collection, there are ClientOperation items representing both the Insert and the Remove, which, despite being inefficient, should still work.  As part of the Insert operation, I am capturing the index property of the node but this throws a NullReferenceException due to, I'm guessing the *pending* Remove operation.

I thought I was maybe using the trackChanges / commitChanges incorrectly and that if instead tracking and committing each operation...

// psuedo code

trackChanges();

insertNode();

commitChanges();

trackChanges();

removeNode();

commitChanges();

...I enabled tracking, performed all my edits and then commited changes, like this

// psuedo code

trackChanges();

insertNode();

removeNode();

commitChanges();

...then it might be smart enough to figure out that net effect is no change.  I implemented this but the same problem exists.

Can anyone shed any light on how to

• Retrieve the index on a node that is subject to a pending Remove operation or
• Cancel the add operation for a node thatis subject to a pending Remove operation

Thanks,

Keith.

I must miss something simple. I set the RadDatePicker as following:

          <telerik:RadDatePicker ID="txtBirthday" runat="server">
                <DateInput Label="Birthday:" EmptyMessage="enter your bithday ..." Width="300px" LabelCssClass="Label">
                </DateInput>
            </telerik:RadDatePicker>

Why I do not see the label "Birthday:" ?

Hi ,

I am adding tabs dynamically and its working fine and scrolling is also implemented and working fine .
But  when i add the tab i want to scroll through it and it will be shown to me .There is a client side event that i get from the
Support from telerik that is  scrollIntoView() but as i am generating my tabs from code behind i want the same feature will be implemented from the Server-side.


Is there any Method that can give me the same functionality from server side.I need this solution urgently .
if not then  in future is telerik is going to provide the functionality from server side also.

Please guide me and answer .

Thanks
Gaurav
