Thank you.

Hi,

I'm having four chart controls (RadHtmlChart) in a page with drill down option for each of it. I'm using onClientSeriesClicked event and thereby using the AjaxRequest event of the Ajax Manager. As I can have only one Ajax Manager in a page, all my chart controls are pointed to the same AjaxRequest event of the Ajax Manager.

Hence when I drill down on one of the charts, all the other charts are also getting refreshed and shows up empty charts. I do not want to load all the charts everytime I drill down. How can I refresh only one chart where I have drilled down and leave all others as is? Please suggest.

Regards,
Muthiah

Hi,

I have a RAD tree view where in i am loading only few levels of Hierarcy data. When i click on a parent node it gets the child nodes by making a call to the database. So basically Load on Demand works when i click on a parent node.

What i want to achieve is expand all parent nodes Programatically from Javascript i.e when i click expandALL it must load all parent nodes child nodes. Basically i want to trigger the onNodeExpand function (which executes on server) from javascript by looping thru all the parent nodes.


Thanks

Hi,
When I click on the Preview button and then again in the Design editor loses the cursor, I can write but can not see the cursor. I came to that as you click to a different place than the Iframe editor then it works and appears to back the cursor. I did also go to edit my own but it will not come. The error occurs in the latest Firefox, I checked the Opera is working properly. The same error is on your side in the demo.

aspx:

Config/radeditor.xml

When a user changes the layout of the grid (e.g., by column resize or reorder), I set value that's read on page_load.  If the value is 1, I save the grid settings.  This works fine for column resize, but not for column reorder, the value doesn't get updated (it remains 0).  I have the column order client events pointing to the same event as column resize (as you can see below), but the method is never called.  (I put a breakpoint on the client function and it's only called on column resize, not reorder).

Here's the grid definition:


And the method definition:


Why isn't the SaveSettingsOnClose method being called when I reorder or sort the columns on the grid?

The second issue has to do with Column sort.  When I sort a column, the server OnSortCommand is called, but when I step through the code and check the grid sort expression count, it's always 0 (even though the visual state of the grid shows the proper sort method).  Here's the OnSortCommand and followon StoreSettings methods:




Why is the .SortExpressions.Count set to 0 even though the grid appears to be sorted properly when looking at it?

Just want to make sure I'm not missing any options.

I have a screen with an html table and I need to put in multiple rows and columns with many radcombo boxes.  
I'm currently running Version 2012.2.607.40.  For 'political' reasons I can't upgrade at this time.

Is there any way at all to set the labels so that the labels and the dropdowns themselves all line up vertically?
(Other than blanking out the dropdown labels and using separate label controls in separate cells?)

Would upgrading to the latest Telerik control set offer any new options?

Hi,

I am having the error while opening up certain pages:

"Error while executing filter ConvertFontToSpanFilter - InvalidCharacterError: The string contains invalid characters."

I know that I can disable the RadEditor filter and it works fine. But what I would like to know is do I have an option to disable showing this message instead of disabling the filter all together?


Thank you,
Ali.

Hello Forum,

My Name is Lukas, I am new to the Telerik Controls. First i want to say that these controls helped me a lot an you musst keep up your nice work!

So now to my Problem:

I got a Grid on my aspx.net Site filled with an EntityDataSource. The Data for this comes from an SQL-Server. On the Top of this Site there is an DropDownList filled with some example companys.

So when i change the company of the DropDownList i want to apply a Filter to the "CompanyID"-Row in the Grid-View with the Index of the selected Item in the DropDownList.

I got the Event from the DropDownList and the only thing i want to know is how i can filter the "CompanyID"-Row from the Grid to the selected Index of the DropDownList. So that the Grid only shows the data where "CompanyID" is for example 4.

Is this possibly and can you give me an example how to do that? I searched a lot in this forum but haven´t found an simple answer for this case.

Kind regards
Lukas

I would like to disable my menu item based on the Active directory login.

I am using SQL data source, My ASPX page and Menu control look like this

<telerik:RadMenu ID="RadMenu1" Runat="server" DataFieldID="ID"

    DataFieldParentID="Parent" DataNavigateUrlField="Url"

    DataSourceID="SqlDataSource1" DataTextField="Title" Skin="Glow"

         EnableRoundedCorners="true" style="z-index: 100000; left: 0px; top: 52px; position: absolute">

        <DefaultGroupSettings ExpandDirection="Down" RepeatDirection="Horizontal" />

</telerik:RadMenu>

<asp:SqlDataSource ID="SqlDataSource1" runat="server"

    ConnectionString="<%$ ConnectionStrings:PROJECT_STATUS %>"

    SelectCommand="PRS_GetWebSiteSiteMap" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

 I have another table which tell me the user login ID and pageID he has access to. So What I want based on the User login I would like to enable the menu pages.

So User Chris with domain\Chris only access to page 1,3,5. The menu control of page 1,3,5 are enabled and remaining all the of the menu control will be disabled.

I hope someone will be able to help me out

Thanks

Hi,

I have a rad scheduler to show appointments and i have recently modified it to use web service binding. I have few client side events on it and one of it is OnClientAppointmentClick. When i click on an appointment, i want a new rad panel to show up adjacent to the scheduler. For this i use a dummy button to post back on the OnClientAppointmentClick event. The issue is that after modifying  the scheduler to web service binding, the OnClientAppointmentClick event seems to take for ever to load and it is affecting the performance. I am not sure if this is caused because post back is causing a conflict to the web service or not.
