GridViewBooleanColumn getcleared when scroll

I implemented a GridViewBooleanColumn so that the user can select a series of rows. If I scroll the selected rows, the values get cleared when I scroll them back into view.

What is the mode for maintain the selected data when scroll back into the view?

Thanks

[Solved] Access the name property of RadButtonElement

Hi,

I have a RibbonBar in my application which contains different RadtabStrip with Chunks and RadButtonElements inside chunks. Now, the problem I am facing is that I need to get through each RadButtonElement on runtime and disable appropriate RadButtonElements according to the condition. The only unique way to identify radbuttonelement is through its name. I am using recursive algorithm to check each element 1 by 1... I tried using 'subelement.Name' property to identify the control but its showing me empty string for all the control names. can anyone help me out with this? I would highly appreciate any help possible.

Thanks

Dock Activation

I've noticed that if you have multiple docks open in the same area so that it creates the tabs at the bottom, there is an odd behavior with activation events.

If you open/create a dock it is the top dock and the activated event fires.

If you open/create another then it is the top dock and the activated event fires.

If you switch back and forth between the two open docks each time you click one it becomes the top dock and the activated event fires.

If however you close the top dock and the one underneath "passively" becomes the top dock, the activated event does not fire. In order to "activate" it you have to click on another dock and then click on that one again.

It seems to me that if you close a dock and a dock below that one now has focus and is at the top, then it should activate.

I use the activated event to do several small bits of processing and for it to sometimes not fire when the user would think it should is cumbersome.

If this is a bug, can a fix be added to the next release?

If this is not a bug, can you enlighten me as to why this isn't the intended behavior and perhaps provide a work around that would handle this case?

Thanks,

Alex

Selecting Tabs via code

Hi,

mabe I'm to dumb, but I haven't figured out how I can select a tab with code.

In the Tabcontrol object from VS05 it's working like this: TabControl1.SelectTab(TabPage2)

How can I realize this with the Ribbonbar?

Thanks for your help.

GridView-Master-Child Relation

Problem :
The Child records in Winforms radgrid hierarchy should show at the first click expand and it shouldn't collapse automatic.

At Design Time, I create Strongly Typed dataset containing two tables
Master table--Company
Child Table---Branch
having Relation in these tables by "Company Id"

At Form load , if we use "AutoGenerateHierarchyFromDataSet" , it takes More time
as it has almost 10000 Company Records and 40000 Branch Records.I think The RadGrid take time to rearrange the records according To hierarchy.

So I tried another alternative:
At time of loading the form ,I fill only Company table.
When I expand any Company ID row, I fill the Branch table only for selected(Iscurrent row) Company Id .Then refresh the Radgrid by
radGrid.Rows(RowIndex).ViewInfo.UpdateView()
As well as
radGrid.GridElement.Update(True)

But the problem is, when i expand the row first time ,The row expands, But does't show branch records for current row Comapny ID.After some time the row automatically collapse.
When I expand ,the same row second time ,it shows the branch(child) records .

This on demand fascility will be helpful for handling large data.

Kindly see in this.
Thanks

[Solved] ListBox ElementVisibility.Collapsed Broken?

Just installed Q3 SP1 and it appears the ElementVisibility.Collapsed property for ListBoxItems is no longer functioning correctly.

I use Collapsed to remove the item from selection without having to do another callback to the database.

Is there any workarounds for the time being?

Also the Rad Checkboxes seem to be very flaky when binding to a boolean via a Binding source as the ToggleState binding doesn't fire off to the underlying object.
