Another GridView Code Example Error

This one isn't big, but it might be annoying, especially to VB coders. In the GridViewComboBoxColumn example, in the Adding and binding GridViewComboBoxColumn section near the top, the C# and VB.Net code samples have different DataSources. The C# one looks to be correct, but the VB.Net one is in error.

One other thing that would help with the code samples is putting each code block in a scrollable text box, rather than having the single scroll bar at the bottom of each entry. Having to scroll to the bottom of the page to scroll to the right and then scroll back up to see the rest of the code is not an optimal solution. Also, and I do not know if this is a Chrome limitation or not, the Copy JavaScript does not work in Chrome 14.0.835.202 m on Windows 7 SP1 32-bit.

Issue with custom statuses

Hi, I am evaluating your product right now and have written a small custom application to interface with my legacy appointment table. I created my own custom statuses and one of my status IDs is equal to 2. Apparently this status id is hardwired somewhere to not show the color associated with it on the left end of the appointment on the scheduler. How can I override this to make the status color show? Changing this ID to something else is not an option.

Thanks!

RadTrackBarElement Back color

Hi,

I have a RadTrackBarElement hosted in a CommandBarHostItem. It displays correctly, and I have configured certain properties such as removing the tickmarks etc. However, I just cannot get the BackColor of the trackbar to take on the colour of the parent item i.e. the CommandBarStrip it is hosted in. The CommandBarHostItem.BackColor is at it's default which appears to be Color.Transparent.

How do I set the BackColor of the TrackBar so that it actually changes? If I look through VSB, it appears that RadTrackBarElement.BackColor is all that's required, but this doesn't work.

Cheers,

Steven

Am I using data binding correctly? (Adding columns to data table)

I have a data table object that I bind a gridview to. During runtime, I'd like to give the user an option to add a column to the gridview. Now ideally the way I thought it would work was if I add a column to the Data Table object that the grid view is bound to, it would automatically add that column to the gridview because of the data binding. But when I try that, only the Data Table is updated with the new column and not the GridView. Am I not using databinding correctly?

Thanks

Layout problems

Hi,
I have a problem when loading a layout configuration file im my application at startup and when I choose to change layout:
My layout configuration is a XML file and i use a RadDock and the method LoadFromXml(path), where path is where the complete path where the layout configuration file is present (*.xml).
The file is present and the layout is correctly loaded, but the application performs a bad animation during the layout update.
My Goal is to hide the layout changing animations and to show only the final result with the windows correctly positioned on the RadDock control.
Is there a way to build the layout without showing the intermediate state of the creation process of the layout, but only the final result?

Populating a group of ImageButton's with Images loaded from SQL Server

I have a list <li> of ASP ImageButton(s) which I want to set their ImageURL properties with images loaded from a SQL Server database.

I've seen people implemeent it in the HTML markup of the using <? Eval("Image"); ?>

That seems to be the approach I am looking for but don't know what else to set.

I have loaded a DataTable object containing just a column-field of type Binary holding Images.

Please advise. Please provide detail examples if possible. :)
