ComboBox Dynamic Load in Grid Item Template

I am trying to get a RadComboBox to dynamically load the content when a user attempts to open the combo box.

The ComboBox is displayed in a RadGrid under the ItemTemplate (yes, not EditItemTemplate).

The problem is I get an error that says "The target {obj} for the callback could not be found or did not implement the ICallbackEventHandler.

What am I missing? Here is my aspx:

<telerik:GridTemplateColumn HeaderText="Employee Type" DataType="System.String" >

<ItemTemplate>

<telerik:RadComboBox ID="uxEmployeeType" runat="server" Width="50px"

DataTextField="Name" DataValueField="ID" EnableAutomaticLoadOnDemand="true"

OnItemsRequested="uxEmployeeType_ItemsRequested" >

</telerik:RadComboBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

And here is my code.

protected void uxEmployeeType_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

RadComboBox uxEmployeeType = (RadComboBox)sender;

uxEmployeeType.DataSource = _empTypes.EmployeeTypesMembers;

uxEmployeeType.DataBind();

}

When selecting "Add New Item", editor iframe doesn't display right-click context menu in IE

I'm having an issue with a RadGrid not displaying right-click context menus in IE. Specifically, when choosing the auto-generated "Add New Item" button, the editor area (which opens in an iframe within the grid) does not allow me to right-click to open a Cut/Copy/Paste/etc context menu. This issue only occurs for me under IE, right-clicking generates a context menu in both Chrome and Firefox. I'm also not using any custom context menus and there is nothing in the code behind that should be affecting this. I'm wondering if there is a known solution to this or if the problem is could be caused by certain settings on the RadGrid or MasterTable?

RadEditor Toolbar Dropdown Will Not Close

Hello, I am using 2014.1.403.40, I have a RadEditor inside a RadWindow. I launch the RadWindow from code using the following:

string script = "function f() {$find(\"" + wPopup.ClientID + "\").show(); setTimeout(function(){$find(\"" + edContent.ClientID + "\").onParentNodeChanged();}, 10); Sys.Application.remove_load(f); EditorWindowVisible = true;} Sys.Application.add_load(f);";

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

When I click/open any of the editor toolbar dropdown controls they will not close unless I click/open another editor toolbar dropdown control. This only happens in Chrome and it doesn't happen the first time I load the site? I don't think it matters but the site is a Sitefinity site. Otherwise the editor looks and is working correctly. I notice if I remove the editor from the RadWindow this problem does not happen and it does not happen in IE 11.

[Solved] Updating batch editor for all rows of the Grid

Hi,

I am attempting to update the checkbox of a GridTemplateColumn via a button on the grid's command bar.
This button should check all rows within the grid, but at the minute my script is updating all rows other than the first one.
It seems as though I must be missing something very simple but I can't seem to spot it!

It's worth noting that the checkbox in the ItemTemplate does get checked for the first row, however it doesn't appear to change the batch editor state, i.e. all rows are checked, but the first row does not have the red indicator to show that the value has changed, therefore a command object is never passed to my OnBatchEditCommand server side function for this row.

I would appreciate any help on this.

Regards,
Mike.

Telerik scripts downloading twice

I have got the Telerik CDN setup as listed in the URL below:
http://www.telerik.com/help/aspnet-ajax/cdn-custom-provider.html

However, it causes scripts to load twice. One file - jQuery.Easing is loaded as part of jQuery.plugins.js and ScriptResource.axd. There are other files that load twice similarly.

The settings I have made are exactly as provided in the URL above. Please let me know if I have missed something and how to resolve this issue.

We are using telerik version 2011.

Splitter Height when using RadAjaxManager

I'm trying to resize a splitter using the HeightOffset="60" property. It works perfect until I add a RadAjaxManager to the page. After that the splitter no longer takes up the full screen like i want it too. This is a simple example just to demo my issue. Obviously i need to keep the radajaxmanager otherwise i would just remove it. Thanks. Any help would be great!!!

Notice in the code below it does not size correctly, but if i remove the radajaxmanager block it works perfect.

Creation and Configuration Wizard & VWD2010 Express

I know that the Express editions of the Visual IDEs don't support third-party extensions (but the controls can be manually added using the zip distribution) and I'm guessing this includes registering the "Creation and Configuration Wizard" but is there any documentation on how to replicate the wizard features manually? I've found the "web.config Settings Overview", which seems to cover some of it but the wizard seems to provide a lot more functionality.

Cheers
