I enabled RadEditor on HTML fields. On an existing page with content and images, I click one of the images, then click Image Manager and it throws the old classic error (in the rad dialog):

'Object reference not set to an instance of an object'

When I don't highlight an image (in the same editor pane), and click Image Manager, the dialog pops up without error. What can be concluded from this? Is the Image Manager trying to set its initial broswe location to an old path that cannot be found?

Here is the Event Viewer Log that it throws:

SelectedIndexChanged on RowDblClick

I am building a user .ascx control that contains a RadGrid. On row double click I have to be able to get Id value of that grid and a value in "Title" column and place them in TextBoxes on a parent form. Now, I have made a custom event for this (called it SelectEvent) which will be handled on parent form, and have defined custom event args class (PickereventArgs with two properties: int ID, string Title). I want to raise that event on SelectedIndexChanged of the RadGrid in .ascx like this

protected void gridPicker_SelectedIndexChanged(object sender, EventArgs e)

{

foreach (GridDataItem item in gridPicker.SelectedItems)

{

if (item.Selected)

{

if (SelectEvent != null)

{

PickerEventArgs args = new PickerEventArgs();

args.Title = item.Cells[1].Text;

args.Id = Convert.ToInt32(item.Cells[0].Text);

SelectEvent(this,args);

gridPicker.DataSource = null;

this.Visible = false;

}

but I can't fire OnSelectedIndexChange with double click on row.
Help, anyone? I need it quickly because I have a deadline and my boss is getting a bit nervous :)

MakeUrlsAbsolute in ContentFilters BROKEN in latest build

Hey guys

Once again a latest build (2012.3.1308.45) breaks a previously working RadEditor.

ALL url's are now made absolute, no matter what the ContentFilter is set. This was WORKING in previous builds.

I am getting very very hesitant in updating to the latest builds from now on as these small issues keep cropping up.

GridButtonColumn Click to update another control on AjaxManager - how to

I have a programmatic created RadGrid that has a GridButtonColumn in it. I also have a Radlistview that I'm using on the same page.

I need the button click on the radgrid to update the radlistview via a Radajaxmanagerproxy. My issue I'm running into is that the GridButtonColumn that adds the button doesn't have an ID that I can link it to. I've tried using the ItemCommand event on the ajaxmanager and I don't get a result.

How would I set this up?

GridButtonColumn bc = new GridButtonColumn();

dg.MasterTableView.Columns.Add(bc);

bc.HeaderText = "Add";

bc.ButtonType = GridButtonColumnType.PushButton;

bc.CommandName = "Add_Click";

bc.Text = "Add";

<telerik:AjaxSetting AjaxControlID="ProductCrossSaleGrid" EventName="ProductCrossSaleGrid_ItemCommand">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadListView1" LoadingPanelID="PricingLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

Adding Telerik Controls Dynamically into a Nested User Control

I am trying to add Telerik’s controls (like RadMaskedTextBox, RadNumericTextBox and RadDateInput controls) dynamically into a user control (under the Page_Init event) which is itself a child of another user control.

When I run the project, following exception occurred and nothing is shown in the user control.

“Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element”

However, these controls are added directly on a .aspx page without any exception and it appeared that the Telerik’s controls get registered in the Page_PreRenderComplete event of an .aspx page and since this event does not exist in a user control therefore they are throwing the above exception.
