Hello
System: ASP.NET AJAX v2012.1.215.40
Visual Studio 2010
We use DatasourceID property and the ShowInsertItem() function of RadListView to display at the same time the data by <ItemTemplate> and the insertion by <InsertItemTemplate>. Everything works fine, except when the data are empty. In this case, the content of <EmptyDataTemplate> isn't displayed if ShowInsertItem() is used.
If the <ItemTemplate> can be displayed at the same time that <InsertItemTemplate>, the display of
<EmptyDataTemplate> should follow the same logic.
Is there an option to force the display of <EmptyDataTemplate> while the <InsertItemTemplate> is showed?
Best regards,
Alain

I am trying to find a solution when user is trying to search for a item and cannot be found. it will return to first item.
When the first item is selected, the cursor is at the end of selected text. Is there any way that when the user start search for next item, it will just clear the selected text. maybe there is a way to highlight the selected text so it will get clear when user start typing?
thanks
function RadComboBlur(source, args) {
var oval = source.get_text();
if (oval != source.get_selectedItem().get_text()) {
var digit = source.get_items().getItem(0).get_value().length;
var val = $.strPad(oval, digit);
var item = source.findItemByValue(val);
if (item) {
item.select();
} else {
if (oval == "") {
alert("Value cannot be empty. Default value is selected instead.");
}else{
alert("Input value does not exists. Default value is selected instead.");
}
var item = source.get_items().getItem(0);
item.select();
}
}
}

Hi,
I have a RadSplitter Control in an aspx page wich contains two RadPanes.The RadPanes Content is loaded from an external source (still pages from my project) thanks to the contentURL property. The rightpane content is loaded dynamically from an event of the leftpane ( a searchbutton click and a node click from a RadTreeView).
In this scenario i would like the content inside the RightPane to be loaded with Ajax.
I read in this forum that in this case, the only way to make it work would be to make an update of the whole RadSplitter.
So i've tried to find a way to programmatically add in the page_load event handler an ajaxsetting to the RadAjaxManager with the RadAjaxPanel where the treeview is embedded as initiator to update the RadSplitter which is in the parent page.
The problem i have is that i can't get the reference of the splitter control from that parent page server side, i've already figured out how to get the reference client side with javascript but the AjaxSettings.AddAjaxSetting server method only accept the server object references as parameters.
Is there a way to achieve this or am i going the wrong way, will this work ?
Thank you

Hi! We’re redesigning our web-site and replacing all our current menus and grids with your RadMenu and RadGrid. I’ve been running into a problem with the appearance of the menu, though. Even though the menu item text looks like it fits within the menu’s width, there’s usually what looks like some kind of padding at the right end of the longest menu item(s). We set the menu item color depending on the item type, but I noticed that the space is even there if I leave the skin with the default transparent settings and just hover over it. I tried setting the width settings, and, if I make them large enough, I can get it to not show that space, but, the problem with that is, we need to add the items dynamically so we don’t know how wide the menu needs to be, and we don’t want a whole lot of extra space with nothing in it.
We have the menu in a user control that we’ll add to each page. We currently have the RadMenu inside a RadSlidingPane inside a RadSlidingZone, and we add that user control to a RadPane within a RadSplitter in the pages they’re added to, but I tried doing it without the splitters, zones, and panes, and it still didn’t do it right.
I was wondering if the problem had to do with the items being adding from the code-behind page instead of from the ASPX page, but I found it did the same thing when I hard-coded them in. I’ve attached a sample image of what the menu item widths look like. If you have any suggestions on what could be changed to get the items to look right, they would be greatly appreciated! Thank you so much!

Hi guys, im hoping someone can help me out here. Getting a strange rendering issue with the datepicker control on the grid when trying to set a date filter. Basically the control seems to be positioned permanently over the grid when scrolling horizontally. I've attached a screenshot showing the problem.As you can see the datepicker for the date column 'Period To' seems to be completely detached from its usual position. If I scroll across the datepicker also scrolls, same applies to all other date columns - you can just about see the date of birth column has the same issue
Any suggestions?
PS I had to blank out some of the data in the grid as its sensitive data

I was following an example I found on the site but for some, and it works up to teh point of finding the link buttons text. I need the linkbuttons command argument or the actual text of the link button becuase this is the parameter I need to send thru the querysting to open that page.
It does not seem to get either method.

So I have a print image as part of my radgrid. What I want to do is hide the image button of there is nothing existing for the linkbutton becuase I hide duplicates of the link button. So where the linkbutton is not there I want to also hide the printer image.
I also tried using it as an e.item.cell(?).text but this did not work either becuase it sees it as a linkbutton column I believe.

Hello,
I have a RadGrid inside a Webpart. Its a non-visual webpart.
I am binding the grid to a Datasource of List<T>.
Every column is being returned from the datasource so I turned off AutoGenerateColumns to remove the extra columns and control what is painted on the screen.
Now the grid always displays "No records to display"...
The radgrid is created in the CreateChildControls override event:
I am adding only one column to see if I can remove the possible reasons for the error:
And the NeedDataSource event is used:
I can see that 40+ records are returned, but its not binding them - is this some strange page life cycle issue?
Please help
