I have a RadGrid which is created programmatically. When I click the Export to Excel or Word button, it raises this issue and I can't debug what's causing it as it's inside the Telerik assembly:

What does AdjustStructureColumnCells() do? any clue what I can do?

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Stack Trace:


            [NullReferenceException: Object reference not set to an instance of an object.]

z index issue on custom dialog

Hi,

I've noticed that image resize handles from the currently selected image in the rad editor have a higher z index than the custom dialog window (see attached, circled in red).

This also happens with the text input cursor.

If you click the dialog the z index is fixed.

I've tried the following css tweak suggested as a fix else where...

.RadWindow .RadWindow_Office2007 .rwNormalWindow .rwTransparentWindow

{

z-index: 200000 !important;

}

... and it does not make any difference.

I'm using the following JS to open my dialog:

function ShowEditor(typeId, inmemoryId, savedId, title, callBackFunction, editorHandle, windowUrl) {

//open a rad window containing the page control editor

editorHandle.showExternalDialog(

windowUrl + '?typeId=' + typeId + '&inMemoryId=' + inmemoryId + '&savedId=' + savedId,

null,

800,

400,

callBackFunction,

null,

title,

true,

Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Reload,

false,

true);

}

Any ideas?

Thanks,

Ian.

Selective suppress the SetImageProperties dialog

Hi,

I'm using the image tag as a place holder for some custom content the up shot is that if an image has certain attributes (some I've made up) I want to suppress the standard image properties editor that the rad editor has built in if the user clicks 'properties' in the context menu.

I've been able to get the suppress to work correctly, but I have also stopped the image properties editor from working when a normal image is used.

My rad editor looks like:

<telerik:RadEditor ID="ucEditor" runat="server" OnClientLoad="OnClientLoad" Width="99%" Height="470px" ToolsFile="~/Resources/Config/RadControls/DefaultToolsFile.xml">
    <CssFiles>
        <telerik:EditorCssFile Value="" />
    </CssFiles>
    <ContextMenus>
        <telerik:EditorContextMenu TagName="IMG" Enabled="true">
            <telerik:EditorTool Name="EditPageControl" Text="Edit Page Control" />
            <telerik:EditorTool Name="SetImageProperties" />
        </telerik:EditorContextMenu>
    </ContextMenus>
</telerik:RadEditor>

I've got the following handler for set image properties:

Telerik.Web.UI.Editor.CommandList["SetImageProperties"] = function (commandName, editor, args) {

var elem = editor.getSelectedElement();

var typeId;

var inmemoryId;

var savedId;

var pageControlName;

//get the selected tag

editor.selectElement(elem);

var selection = editor.getSelection();

var selectionHTML = selection.getHtml();

//attempt to retrieve the parameters we need from the tags

//attributes

typeId = $telerik.$(selectionHTML).attr("typeId");

savedId = $telerik.$(selectionHTML).attr("savedId");

inmemoryId = $telerik.$(selectionHTML).attr("inMemoryId");

pageControlName = $telerik.$(selectionHTML).attr("pageControlName");

//check if this is a dynamic page control place holder

if (typeId != null && savedId != null && inmemoryId != null && pageControlName != null) {

//user has selected an dynamic page control and is trying to edit it using the image manager - must prevent this!

alert('This is a dynamic page control, please click Edit Page Control to edit it');

return; //disable the browsers context menu

}

I suspect I need an 'else' part to go with the if but I'm not sure how you would manually invoke the image properties editor.

Thanks,

Ian.

Access key not working some browsers

Hi, I've been adding access key support to a RADMenu that's included in an application using the ASP.NET AJAX Q1/2011 release. The access keys work fine in IE9. In Firefox 5, using the ALT/SHIFT/key combination works but it starts the cursor flashing! Using Chrome 12 and Safari 5, the ALT/key combinations don't appear to work at all.

All of these issues are demonstrable on your own demo page at...
http://demos.telerik.com/aspnet-ajax/menu/examples/functionality/keyboardsupport/defaultcs.aspx

Are browsers other than IE supported by the access key feature in RADMenu?

Best regards, Ian

properties editor doesn't support fields-prompt

hi,
I just upgrade my Aspnet ajax to ver 2011 Q1, my question is: in Grid's properties editor, I couldn't find fields-prompt support for DataKeyNames input, parent table relation defining (as attachment)..., even I've defined the DataSouce name. RadGrid doesn't support this feature or I got the wrong design step?

filter by DataKeys or DataItem's text?

I am using a RadFilter with a RadGrid. So far I have only got the RadFilter to work when my FilterExpression's FieldName is equal to a GridBoundColumn's DataField.

I have a column where the text displayed to the user is a concatenation of 3 fields from my DataSource. However, I want the user to be able to filter by each of these fields individually. Adding the individual fields as DataKeys did not work. Right now I have it working by having 3 GridBoundColumns with DataField set to each of the 3 individual fields, and Visible=false. Are there any performance implications to this approach? Even if there aren't any, I still think it's messy code. I would prefer to use the DataKey if possible.

I have another column where the value from my DataSource is an int. However, to get the value I display to the user, I cast this int to an enum and call ToString(). I am building my filter expressions programmatically. Right now it seems like I would have to build a RadFilterEqualToFilterExpression<int> for this column. However, all my other columns would use RadFilterEqualToFilterExpression<string>. My code would be much simpler if I could use RadFilterEqualToFilterExpression<string> for all my columns. Is it possible to filter by DataItem["uniqueName"].Text?

Thank you!
