Persisting data of RadTextBoxes created with ITemplate on Postback

I have a DetailsView control that I'm adding RadTextBox's via the EditTemplate. An DataBinding event handler is added to each rtb.

Everything works fine except when I go to Update or Insert a new record. When it comes time to grab the data values from the textboxes, they either have their default values from the databind or their empty. Because Templates need to be created on every post back, I'm struggling on finding a solution for persisting the values that were in the textboxes prior to the post back. Any assistance would be greatly appreciated.

Thanks
Alex

Internet Explorer IE lock up freeze after page load

Hi,

After the page has loaded there is period in which IE, both 6 and 7, locks up. The page has already loaded but there is some kind of pre-processing taking place.

If this were to happen on the first load of the site only and subsequent loads were unaffected then it would be acceptable. Firefox has a delay but it is tiny and acceptable.

I have been trawling through the documentation but can find no mention of this, how can this delay be removed or contained to first load only?

Here is a video demonstrating the problem.

Thanks,

Leon.

RadTreeView disappearing on Postback

Hi,
I have a master page that has a RadSplitter on it with 2 panes ... left and right. On the left pane I have a RadTreeView. On the right pane I have the content.

Most of the time I use a RadAjaxPanel or the RadAjaxManager. However, on the page I am having a problem with, I am using a FileUpload control which means no ajax.

As a result any postback and the tree disappears. If I remove the FileUpload and just have a button on the content page with no RadAjaxPanel the tree still disappears.

Any ideas?
Thanks ... Ed

hide/show table in panelitem on expand/collapse via javascript

We have a situation where a lot of RadComboBox's are being rendered in panels that are closed during the loading of the page. I am not sure why this is happening, but making those tables hidden initially drastically reduces the page load time.

Now we want to be able to make the table in a panel that is clicked on visible again when it is expanded and hidden when it is collapsed. We are doing this client side since server side makes the whole page refresh which then kills the load times again as you open all the panels.

I have tried many different ways to get this work using examples on the site and through other post and can't seem to get the right combination. Any help would be appreciated on how to do this or how to make the panels not try to render the combobox's when they are visible to begin with. Thanks!

How can I validate the controls?

Is there any way to validate the text that is entered either in the filter or when editing a record?(for example a datetime field generates error if the user enters something else).
Thank you.

Stuck on Collapsed

I have two panels set up that toggle their visiblility. The first panel contains a splitter with two panes and a split bar in between. If the first panel is visible, i can expand/collapse my pane's without a problem (initially). If i collapse the a pane, then make the first panel visible=false....then make it visible=true, the panes are "stuck" in collapse mode. I cannot resize or expand. any ideas?

Is it possible to add color coding to the HTML tags in the Editor?

Does anyone know if it is possible to enable some type of color coding of the HTML code in the editor. Something that would help distinguish HTML elements from actual content. Something like what is used by VS.NET and many other popular HTML editors.

Thanks!

Skin registration in WebForm contentplaceholder

Hi

I have a webform that uses masterpage. I want to register my custom skin for use in the webform. I have a contentplaceholder in my masterpage within the html head. In my webform, i place my skin registration (link) in the content for the contentplaceholder. The skin doesnt seem to get loaded. If I put the skin reg directly in the masterpage html head, the skin is loaded properly. Is this a limitation or am I doing something wrong?

Thanks in advance
