Why do AddNewRecordButton and InitInsertButton behave differently and how to overcome this?

I'm using the radgrid to display/sort data and maintain consistency in the app, but editing and adding of one particular grid is handled by another control due to complexity.

I'm able to handle most of this in the OnItemCommand event with either RadGrid.InitInsertCommandName, RadGrid.EditCommandName etc. The part I'm having trouble with is the actual Add button. The "Add new item" LinkButton works fine but the "+" button never hits the OnItemCommand event even though they presumably would be doing the exact same thing. What do I have to do?

Controlling the position of results

The RadComboBox appears to position the results of the ItemRequested event so that the most number of items can appear - for example, if there are 100 results returned, and the bottom of the browser window is closer, the results will appear above the box.

Is there any way to force the results to always appear below the combo box?

Databind problem with SelectedValue not in item list

I have a databound RadComboBox (with databound item list). If the SelectedValue is not in the item list I get a "Selection out of Range" exception.
Is there any way to prevent this and just set SelectedValue to null?

Thanks!

Binding to an OpenAccessDataSource

I'm having an issue binding to an OpenAccessDatasource

I have my DS on the page, and I link it to the combo, all works well, but if I specify a DataText or DataValue field in one of the linked objects it throws an error saying that property doesn't exist (when it does)

So this works
DataTextField="RotationID" DataValueField="RotationID">

This fails
DataTextField="Rotation.RotationName" DataValueField="RotationID">

[Solved] Rad Controls Disabled in Ajax Panel

I've got an Ajax Panel on a page which contains some standard asp controls (text boxes, check boxes etc) and also a Rad Combo, Rad Rating and Rad Editor.

When a record is selected in the search results Rad Grid the items within the panel are updated and the panal refreshed using the Ajax Manager Proxy (within Masterpage).

However the 3 Rad controls are not selectable, the Rating is populating with the correct value but it cannot be selected, not can the combo box or the editor but all the other standard asp controls are fine...

The control of the Ajax Panel is AjaxPanelMain and the Rating is RadRatingHotel...

                    End If  
        
            End Sub

When the Page loads it displays only the parent rows. The parent rows have the expand/collapse column but no child rows.
If I take out the filter on Page_Load it returns ALL rows but there are at the same level (no hierarchy)
Any suggestions?
Thanks.

Radgrid not refreshing

Now this is very odd.

I am calling a radGrid's AjaxRequest to populate new data once a combobox has a new item selected. The grid is placed within a radPageView.
I am using RadAjaxManager and so I have set the "AjaxSetting's ControlID to the grid's ID ,Everything seem to work as expected. But the grid does not seem to refresh. I can debug the code and see that the server side code does fireup and the grid rebinds successfully. It just does not show up on screen

So how come this behavior actually changes depending on the platform the ASP application runs on? And why doesn't the grid refresh in first place?

Thanks for your support!

Best regards,
ANu

Show DetailTable inside the column of a Grid?

Is there any way to nest the DetailTable (i.e. child rows) inside a column of each parent item in the grid? (instead of the user having to click on the expand button to show the child rows for each parent item) I want the grid to show each parent along with their children upon page load (the child rows would be embedded in a column within each parent).
