Validate controls in a radGrid collapsed Nestedview

I have a radgrid and each row has a nestedview.

Inside these nested views, a number of textbox controls are dynamically added using a repeater control.

Some, but not all, of these textboxes require a value to be entered.

If the row is expanded, then validation occurs on the controls that require it. If the row is collapsed, then no validation occurs.

How can I force validation even if the row is collapsed, whether it has ever been expanded or not? As I understand it the nested view isn't loaded until its required? Is there a way to force the nestedviews to be loaded but hidden when the page loads, or can anyone thing of another way around this?

Basically, I need a RadGrid to have a hidden list of controls that are shown when the user expands the row, but need to validate all controls, even if the row hasn't been expanded.

GroupSettings 100% Height of RadPane

Hi,

I have a menu set to the left of my page inside a pane of the rad splitter. The splitter is working at a 100% height.

The menu can get longer and shorter as the user browses through site, ie: The sub menu items open up underneath the main menu items on the left and extend it.

The problem i am having is this:
I dont want a scroll bar appearing when the menu is higher than the users viewport, instead I want it to rather display the "GroupSettings" images to scroll the menu. The only problem is it that I dont want to set a fixed height to the GroupSettings option as it will then crop off the menu and look funny if the user viewport is higher than the menu height specified in GroupSettings.

Is there a way to set the value of GroupSettings to 100% height so that it will always sit on the top and bottom edges of the radPane and if the user's viewport becomes smaller than the actual menu height then the scroll buttons will "activate" and the user will be able to scroll the hidden menu items?

I suppose there should be someway to pull the height of the radPane using javascript as it changes and set the groupSettings to use that height. So as you resize the viewport, the radpane height value gets used for the GroupSettings value for the menu?

Your help with this would be greatly appreciated!

Self-Referencing Heirarchy

My employer has a use case that would work great with the self-referencing heirarchy, however, the default behavior does not quite match what we want to do with it, and I'm at a loss for trying to get it working the way I want to.

Our data model is represented using objects (not DataTables or DataSources) and is bound as a list of objects to DataSource in NeedsDataSource.

1. We only want to show root nodes on the root node. From what I can tell, a simple FilterExpression on the MasterTableView fixes this.
2. We want to allow sorting, filtering, paging, grouping, etc.. I was able to fix this by turning this all on and then turning it off on the child grids on pre-render.
3. We want the filters to also apply to the child grids AND include the top level node if a child node matches. <-- this is where I get stuck. I figured a custom filter expression combined with a method on each object that returns true if that item or any child item matches would work, but it doesn't seem as if calling custom methods on the objects is allowed in FilterExpression.

Making expand/collapse button wider than the split bar

I would like to change the appearance of the expand/collapse button of the split bar to be wider than the split bar itself, making it a tab that overlaps the pane next to it. My goal is to make it more visible than the default appearance. See the attached screen shot for an example of what I am seeking. My attempts at increasing the width of the button also increased the width of the split bar, which I don't want.

Is a style like I am seeking possible?

Thanks!

Refresh control outside AjaxPanel

If you look at the screenshot I provided, there is a toolbar with a house, export and import.

If I select a type of bulletin board, must show a button after the house.

My problem is this. The DropDownList is in a RadAjaxPanel and ToolBar is a external. I can not use this example because RadAjaxManager content-year white space is dynamic. The toolbar is always present in any important case.

How do I select if "Important messages", my toolbar is refreshed as if I did not RadAjaxPanel everything works.

Using treelist without children

Hello,

I have created a usercontrol where I show an overview of rows from an entity. So far all this entities had a hierarchie (parentid). Now I have an entity (table) without a hierarchie. In other words, the treelist only have to show one level. Because I want to reuse this usercontrol I like to know if it is possible. I had removed the property ParentDataKeyNames but that the Exception:

KeyNames collection length must match ParentKeyNames collection length.

Is it possible what I want?

Kind regards,

Patrick

Popup FormTemplate Height

I am using a popup edit form with a form template. I found the javascript to center the popup window which is working perfectly. However, I cannot seem to get the bottom of the form to fit within the popup window. It overflows on the bottom. I have tried setting the height of the popup window in the popupsettings and also setting it in the javascript with no difference. How do I tell the FormTemplate not to overflow the bottom of the popup window? I am attaching a picture of what I mean.

thanks!
