Treelist Excel Export Not Showing Header Text

Hi,

I have a TreeList with AllowLoadOnDemand="true". When I export the TreeList using the following code, the exported document has a blank row for header as can be seen in the attached screenshot.

protected void radButtonExcel_Click(object sender, EventArgs e)

{

rptTreeList.ExportSettings.IgnorePaging = true;

rptTreeList.ExportSettings.ExportMode = TreeListExportMode.RemoveAll;

rptTreeList.Rebind();

rptTreeList.ExportToExcel();

}

Please Help!

Thanks,
NA

Tooltip closing problem

Hi,

We are having major problem with the tooltip closing unexpectedly...

In your demo:
http://demos.telerik.com/aspnet-ajax/tooltip/examples/overview/defaultcs.aspx

Change to:
HideEvent: LeaveToolTip
RenderMode: Lightweight

After the tooltip is displayed, move the cursor slowly (moving really fast wont reproduce the issue!), from the top or from the left until the cursor is above the tooltip. In this case the tooltip closes immediately when entering the tooltip!!!

If moving the cursor from the right or bottom into the tooltip, this does not happen.

This issue happens all the time for our users since the tooltip in our case always are located directly to the right of the hovered element, and users often moves the cursor just a little bit to the right and the tooltip closes...

Tested in Firefox and IE10, same behavior.
Only happens in Lightweight render mode...

Regards
Caesar

I don't know what is the problem, but the filter is doing its job only by the day of the month.
I will appreciate if you have a look on the following.

Thank you in advance.

Regarding Upgrading to Latest Version

Hi,
I am trying to upgrade the Telerik dll in a project from version(2010.3.1317.40) to version(2013.1.417.40).
I have removed the older version dll and then I have added the latest version dll.
But when I run the project after building the prioject I am getting an exception like given below
"Could not load file or assembly 'Telerik.Web.UI, Version=2013.1.417.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference".

I have googled on this and got the below links
http://www.telerik.com/help/aspnet-ajax/introduction-troubleshooting.html
http://www.telerik.com/support/kb/aspnet-ajax/editor/error-could-not-load-file-or-assembly-telerik-web-ui-version-xxxxx-x-xxxx-x-culture-neutral-publickeytoken-xxxx-or-one-of-its-dependencies.aspx
http://www.telerik.com/help/aspnet-ajax/introduction-upgrading.html

I have followed exactly what Telerik Experts mentioned in these links. But still I am getting exception.

On further investigation I found out that there is another dll namely "RadTreeview.Net2.dll" in my solution.

Will this have any effect for this issue.?

Please suggest me a work around for this issue

Dual ListBox Item State Issues

Hi,

I'm using two lists as a dual list. I need to enhance the lists in a few ways: allow checkboxes in the destination list, only allow ONE item to be checked in the destination list, and enhance the items in the destination list to provide obvious visual cues for users.

All the code is in a user control - the lists are completely programmatically created and jquery is used to do some of the client-side magic. I am having state issues, though.

Issue 1 - move an item from the select list to the destination list. Check the item then move it back to the select list, using the To Top button. Note the item's style (now in the select list) has taken on the Red style of the inserted span from the destination list. It should be back to just a regular list item with the select list's default style.

Issue 2 - now move the same item back to the Destination list. Note that it somehow retains its checked status and the additional span I added. It should be back to just a default unchecked item (which then gets styled blue). With multiple items in the bottom list, in this manner it's possible to end up with 2 items checked in the destination list.

Issue 3 - now uncheck the item then move it back to the select list, using the To Top button. Back to the Red style???

All these issues are related - the list is trying to preserve item state. I need it to forget the item state and just let the items fall back to their default state so they can be predictably manipulated.

There is also a block of code commented out in the .js file in which I explicitly remove all the changes I make to the items. This code doesn't work either, as spans get moved around when the listbox is trying to preserve their state.

Thanks in advance for your input.
