"Check Spelling" Text Not Localized

Hey..

When I'm using the localization feature of RadEditor, almost all the things are getting localized or there are fields in the resource files to change their value for particular language. But "Check Spelling" Text is not getting localized, and there is also no field mentioned for it in the Resource files. Please provide me the solution for this as it is very important for us.

Thanks in advance,

Editor

Error using Stored Procedure as source which contains a left or substring command

Hi,
I'm using for the Grid a stored Procedure with a parameter as the source.
This stored Procedure works fine. but when i open the "configuration wizard" and i insert the value in context window "Refresh data source schema" i'm getting the error "unable to receive schema. ensure that the Connection string and Selectcommand property are valid. invalid length parameter passed to the LEFT or SUBSTRING function"
When i run the page it woks fine! in case that i need to configure a hierarchical grid i like to open the wizard where i get the error :-(
this is my code:

aspx page:
***********************************************
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

<div>
</div>
<div class="demo-container no-bg">
</div>
<div id="AlertDIV" runat="server" class="AlertBOX">
<table>
<tr>
<td>
<asp:SqlDataSource ID="mnv" runat="server" ConnectionString="<%$ ConnectionStrings:connBTDashboard %>" SelectCommand="sp_Playground" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter DefaultValue="1" Name="dfg" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="mnv" GroupPanelPosition="Top">
<GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>
<MasterTableView DataSourceID="mnv">
</MasterTableView>
</telerik:RadGrid>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
***********************************************
ALTER proc [dbo].[sp_Playground]
@dfg int
as

Declare @Cols varchar(max)= ''

DECLARE @SQL varchar(max)

select @Cols += '['+ [col_Name]+'],'from [dbo].[tbl_Conf_MultiNAV] where col_Group = @dfg

Set @COLS = left(@COLS,len(@COLS)-1)

select @Cols as Value

--********************************
--call of SP in Management Studio => works fine
--********************************
exec [sp_Playground] 1

as a remark ... this code in my test to rebuild this error i have in another project ;-)

i'm using .net 4.0 and UI Version 2015.3.1111.40

does anybody had that problem already ?

thanks a lot
cheers

Need OnClientTabSelected to Fire even when already selected

Hi,

I have a tabstrip with 2 levels of tabs - the main/root tabs and child tabs.

All tabs are dynamically built at runtime using client side code and web service calls.

See the attached screenshot for an example.

When the user clicks on the main tab, an associated diagram is displayed.

When the user clicks on a child tab, a sub-diagram is displayed.

This all works fine.

However, if a child tab has been selected (causing a sub-diagram to be displayed) and the user wants to go back to the main diagram, if they click on the main tab at this point no event is raised (since the main tab is already selected).

Is there anyway to force an event (preferably OnClientTabSelected) when the user clicks on an already selected main tab?

My thanks in advance for any advice.

Jim

AccessKey and IE11

I have recently updated my browser to IE 11 and I have the latest version of the AJAX controls. It appears that your keyboard support for TabStrip no longer works in IE 11. I went to your demo and it appears not to work there either. http://demos.telerik.com/aspnet-ajax/tabstrip/examples/functionality/keyboardsupport/defaultcs.aspx

Thank you for looking into this.

Fire a pop up from displayed image

Hi

I'm using the image gallery as per this example http://demos.telerik.com/aspnet-ajax/image-gallery/examples/overview/defaultcs.aspx

i.e. no thumbnails just shows an image with the Prev / Next buttons.

What I want to do is on click the image is open the image in a pop up window - I want to use this lightbox control http://lokeshdhakar.com/projects/lightbox2/

How would I attach the mark-up to the displayed image in image gallery.

This is the mark-up required by the control:

OR can you do what I need to do with your controls.

AutoCompleteBox timing / wrong results are shown

I'm using the AutoCompleteBox with an Array datasource with about 1000 items. The minimum search limit is 3 characters.

When typing for example "JOHN" with a somewhat lower pace, the Postback fires as soon as the "H" is typed (third character, as expected).

If you continue typing the "N", another Postback fires.

However, the resulting drop down list is the result of the first query and shows items that do not match "JOHN". The results of the second Postback are discarded. The user must now add or remove characters from the search string to get the desired result.

It seems that there is a problem with this control, which causes subsequent Postbacks not to be handled correctly. It would also be nice if it would be possible to control the timing behaviour, for example to set a higher value for the time that must pass before a Postback fires.

regards,
Peter
