Problem with item image in Chrome when clicked

Hi,

I'm trying to use RadPanelBar item with NavigateUrl. When the page loads, the image displays correctly. When I click on the item, the image is replaced momentarily by some other image (chrome missing image?). Then the new page loads. This doesn't happen in IE, the correct image is displayed even after clicking. Here is the definition of the RadPanelBar:

<telerik:RadPanelBar runat="server" ID="rpbMain" Height="100%" Width="100%" ExpandMode="SingleExpandedItem"
BackColor="#E4E4E4">
<Items>
<telerik:RadPanelItem runat="server" ImageUrl="~/Images/Inputs.png" NavigateUrl="~/WebForm1.aspx"
Text="Root RadPanelItem1">
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelBar>

I have attached an image which displays the behavior. Chrome is up to date (34.0.1847.131m). Telerik.Web.UI is at 2014.1.403.40. VS2010, .NET 4.

Thanks.

Extra grid whitespace (and other odd behaviors) after publishing to dev server

When I publish my project to our dev server, we start seeing weird behaviors that don't occur with the same code run on my workstation.
The most noticeable is extra whitespace to the right of grids.
Please see screen captures attached - no whitespace appears when I run the project locally on my workstation.

The other weird behavior is Tile drag and drop within a tile list.
Running the project on my workstation it behaves correctly.
Once published to our dev server, as soon as you click on a tile, it immediately jumps up about 150px from the cursor position. Please see screen capture attached.

Best I can tell, all the code and binaries are the same on the dev server as my local workstation.
Can't figure out what the difference is.
I don't think any Telerik binaries are installed in the GAC on the dev server.

Is there a setting in IIS or some file permission that needs to be adjusted on the dev server? It seems like maybe some style information is getting blocked when the project is run on the dev server.

Thanks for your help!

Ajax RadComboBox issue?

Hello,

we are encountering an issue on production with Telerik.Web.UI RadComboBox,
let me describe the detail, but when we deployed to public website , the issue happens occasionally when SelectedIndexChanged(serverside) event was triggered, and actually,in this event ,logic is pretty simple, just retrieve attribute of webcontrols,and build a string.

we could not reproduce this exception in DEV or UAT environment.

the version of Telerik control is 2013.1.417.40

Any help would be appreciate

Q1 2014 Rad Menu

Hello
Quick question, how does the rad menu choose the render mode. Is it done via javascript or purely css ?

The Reason i ask is because i would like to get the radmenu to render in mobile when screen size is below a certain width rather than just device type

Regards

Dave

OnTextChange causes loss of Value property?

Hi

I'm using v2012.3.1308.35 and am running into an issue where I am getting an empty Value for the selected entry in the autocomplete box.

Here's my markup:
Note that InputType="Text" and I have registered an OnTextChanged handler.

<telerik:RadAutoCompleteBox

ID="OperatorAutoCompleteBox"

runat="server"

DataSourceID="sqlOperatorsLookupList"

DataTextField="Full_Name"

DataValueField="Operator_ID"

Filter="Contains"

InputType="Text"

OnTextChanged="OperatorAutoCompleteBox_SelectedOperatorChanged">

<TextSettings SelectionMode="Single" />

</telerik:RadAutoCompleteBox>

Now in the codebehind if I do the following, then the selectedText gets the actual selected text but the selectedValue is an empty string.

If OperatorAutCompleteBox.Entries.Count > 0 Then

selectedText = OperatorAutoCompleteBox.Entries(0).Text

selectedValue = OperatorAutoCompleteBox.Entries(0).Value

End If

Strangely the Entries(0).Value starts to function normally (i.e return the selected value) if I remove the OnTextChanged="....." line from the markup. So to me it seems like registering the OnTextChanged somehow causes the RadAutoCompleteBox to lose its Value property.

Is this a known bug?
Could this be something from the remains of when InputType="Text" did not support the Value property?
(see: http://www.telerik.com/community/forums/aspnet-ajax/autocompletebox/entry-value-is-empty.aspx#2219318 )

FYI - Switching to InputType=Token, or removing the OnTextChanged is not an option for me as I need to limit a single selection and also use the OnTextChanged to populate other controls on what the user has selected.

Thanks

How to delete temporary file

Suppose a file is uploaded, placed in the temporary folder, the page posts back, but then an error or something occurs before calling

UploadedFile.SaveAs().

In that case, the temporary file is not deleted, and over similar repeated events, those files will accumulate on disk. Is there any way to manually cause the temporary file to be deleted?

Thanks.

RadSplitter - Resize with Content

Hey there!

I actually have searched the whole forum and found no specific solution to my problem - even though I am sure, somebody else has the same needs I do.

I have a header, a footer and a content Div in the middle with a Splitter control. Setting width and height to 100% with height offset (just like in your example) works fine, but then depending on the height of the content each pane has its own scrollbar.

My goal is to have one scrollbar for the whole page, so the splitter should resize its height according to the content of the "longest" pane. I just found a solution here with javascript getting the inner height of the panes, but this does not work on runtime (for example with an accordeon control inside the pane!). Is there any other chance to basically make the splitter to not define the height of the splitter-table at all? That would be the easiest solution for me by far, because then every browser would resize the splitter-table perfectly according to the content.

Thanks a lot in advance, sincerely,

Felix (from Germany, excuse my english)

radgrid not loading on pageload when RadAjaxManager present

Hi,

Since adding a RadAjaxManager to the page my RadGrid isn't being populated on page load. there are 2 dropdowns that when changed will trigger the grid being updated, I just can't get it loading correctly.

Works 100% fine with the manager removed.

Note; there is no backend code. there is nothing on the Masterpage other than a single RadScriptManager.
Thanks in advance for any help you can provide.
