Binding Issue

Hi... I am using your Muliticolumn combo box version 2010.3.10.1215
I have a binding issue..
I have declared two DataAdapters and DataViews and populated them from a database... I am attempting to late bind the multicolumn combo box to the two dataviews

The code I have used is

cboLookup.DataBindings.Add("SelectedValue", dvData, "RecordID")
cboLookup.DataSource = dvDisplayList
cboLookup.ValueMember = "RecordID"
cboLookup.DisplayMember = "ShortDescription"

the combo properly populates and displays the contents of the datasource (dvDisplayList)... but does not bind the selectedvalue property (or the selectedItem for that matter). So as I move through the items in the dvData dataview, the combo does not display the corresponding entry in the datasource, it selects the first record and does not move.

I attempted the same code with your RadDropDown list, and it responds as I expected. I found when I simply added the Rad Drop down list to the form along with the multi column combo box the multi column combo box behaved as expected.

Am I doing something wrong here...?
Thanks for any assistance..

[Solved] Q2 2011 Upgrade Wizard Issues Resolved

We identified several issues with our new Upgrade Wizard shortly after our Q2 2011 release.

The following circumstances are known to cause issues when using the Upgrade Wizard:

Having any invalid references in your project (marked with a warning sign in Visual Studio)
Having COM references in your project
Holding a project reference to a project which has not yet been built
Holding a project reference to a project whose output assembly name differs from the project's name

All of the above issues have already been addressed and an update has been released through the Visual Studio Online Gallery:
Telerik WinForms VSExtensions

You should be able to use the Visual Studio 2010 Extension Manager to download the update.

In case you are using Visual Studio 2008 and cannot get updates through the Visual Studio Online Gallery, you will be able to benefit the update when our next Service Pack release.

Best regards,
The Telerik Team

ToolTip Duration

I'm using the ToolTipTextNeeded event to provide Tool Tips over date controls in our RadGridViews. Is there a way to specify the duration that it stays visible, hover time needed to invoke, etc...? Our users would like them to stay visible longer. Thanks...

CausesValidation between Main Form and Child Form

Hi,

I have a problem on the CausesValidation between Main Form and Child Form.
In the Main Form (midChildContainer form), I have a commandbar control with 2 buttons. When those buttons are clicked, a function in Child Form will be involved.

However, I want the validating event in the child form to be triggered when the first button in Main Form is clicked. When, the other button is clicked, the validating event should not be fired.

I tried to set the causesvalidation in CommandBar to False. Then, whatever buttons is clicked, the validating event never fire.
Is there any way to do? Thanks!

[Solved] Pan and Zoom an Image

Is there a RadControl for WinForms that will do this?

When I google on this, I see examples on how to program the default PictureBox control that ships with Visual Studio, but I was wondering if there was an existing RadControl that can already do this, and save myself some development time.

Thanks
