In IE 8 we experience problems with the image and document manager. We cannot browse or upload files. All other browser (including IE7) are working correctly.

We tried the meta tag <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> to solve this problem without success. Can anyone please help me solve this problem?

Below the exception:

"Webpage error details

[Solved] Conditionally showing Delete Icon on row

I have a grid, which has the following GridButtonColumn defined:

                                    <telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" ConfirmText="Delete this selector?"         
                                Text="Delete" UniqueName="DeleteColumn">         
                                <ItemStyle CssClass="EditImageButton" HorizontalAlign="Center" />         
                            </telerik:GridButtonColumn>         

>

On some rows that are shown in the grid I would like to hide the DeleteButton (i.e. these are rows that can't be deleted by the user) -- how do I conditionally hide the delete button?

Thankyou.

DockingZone problem

Hi!

I am trying out DockingZone with the toolbars which is a great feature but I get some weired graphics.

Edit: The toolbar is re-added at every postback. Which means I get many identical toolbars in the dockingzone.

Screendump is attached. My DockingZone div

Another question. Is it possible to move the location of the edit mode buttons? Is it possible to change the appearece of the buttons? I want them appear in the toolbar. I have achieved this by adding custom buttons (as you can see in the screendump) but when the editors mode is 2 or 4 the toolbar is disabled which makes it hard to switch back to the designer mode =). Any work around?

[Solved] RadAjaxLoadingPanel causing AJAX controls to disappear during AJAX postbacks

Hi,

Whenever I put a RadAjaxLoadingPanel on my form and set it to be used by either a RadAjaxPanel or RadAjaxManager, it causes the controls within the panel or or those managed by the manager to disappear during AJAX postbacks (they reappear when it is complete).

I've tried playing with the transparency, size, positioning, etc. Nothing makes any difference.

What am I doing wrong? This can't be the intended behavior.

Client selection gets lost on postback

Hi Guys,

I am having a problem where I have a grid that has client selection enabled. What happens in this grid is that when I select an item or record in the grid, the client selection gets lost on post-back.I have set the EnablePostBackOnRowClick property to true. If I turn this property to false, the selection is possible, but then there is o postback.

What could be causing this?

[Solved] Editor not posting value/text in Firefox 3.5.8 but works in IE

HI,

I'm building a composite control in Asp.net and having a problem with the RadEditor not returning values on form post. I'm using an updatepanel in which I have various RadComboBoxes, RadTextBoxes and a RadEditor, upon submission of the form the ComboBox and Textbox values are returned fine however the RadEditor returns an empty string. Is there any way to fix this, in IE8 it works fine, the problem is confined to Firefox.

Handling button click events in ITemplate object used for NodeTemplate

Hello, I have a custom ITemplate class that I am using to format the output of nodes in a RadTreeView. In the template, I have several asp:Button objects. I want to wire up the Click events of each, and handle them on the page with AJAX calls to server-side methods. I have added event handlers for each button to the ITemplate object but as far as I can tell they never fire. When I click the buttons on the page I get an error message that tells me that ViewState has failed to load, but nothing else happens. Do I need to do anything special to the page in order to handle the events?
