Got a notification to upgrade, so I did...I have 3 projects under my solution, 2 of which use Telerik WinForms...one project updated just fine, the other fails...I get the following error message:

Error executing custom action
Telerik.WinControls.VSXActions.UpdateReferencesAction: Object
reference not set to an instance of an object.

after which, it removed all Telerik references from the project in which it failed...now it gives me the option to 'Convert to Telerik WinForms Application' which I tried...then I selected the GridView, which auto selects the other ones that are needed...I click finish, and I get the exact same error as above.

thoughts?

Adding Multiple Header Rows at Runtime in RadGrid

I need to build a grid with 2 header rows where each column in the 1st header row groups few columns in the 2nd header row.
And the 2nd header row is in 1:1 relation with the grid columns.

For example:

Sunday			Monday
Morning	Afternoon	Evening	Morning	Afternoon	Evening

How do I implement that in RadGrid?

Thanks in advance.

[Solved] RadGridView horizontal scroll not working :(

Hi guys,

Im only just starting to use Rad controls for winforms, and i know i have such a stupid question. But how do i get a horizontal scroll bar to work with the RadGridView. Il explain my problem below:
Eg - i have 10 columns in the grid, and havent actually set any specific widths on them, and call

radGridView1.MasterGridViewTemplate.BestFitColumns();

Now when i click one the columns to make it autosize to fit its contents, eg a column that has a long sentence in it, i expect to see a horizontal scroll bar so that i can stil scroll to view the other columns. But unfortunately the scroll bar never shows up :( Even though HorizontalScollState = AutoHide. All i simply want is for a scroll bar to show up when there are too many columns.

I must be missing something for sure! Do i need to set specific widths on columns, so that the scroll bar comes up and works?

Thanks for any suggestions.
Chris.

Removing table borders

Hi,

I am using the RadRichTextBox (RRTB) to display HTML code. This works well, however there is an issue with the border of the table with which I am unable to remove, and remains black between cells. I have tried to use iinline attributes such as style="border:none" and style="border-collapse:collapse" without success.

Are any style attributes for tables supported? Please help!

HideSelection doesn't

Hi there,

I am working on a custom theme based on ControlDefault
I have a form containing multiple grids and i want to use the HideSelection property to remove all row and cell highlighting when focusing on a different grid.
I've managed to get the theme to do this mostly, the only part i cant figure out is how to remove the cell highlight (see attached screen shot).

I've removed the border from GridDataCellElement.IsCurrent, but left the one for GridDataCell.IsSelected. it seems like no matter what i try, the border still remains.

Hope someone can help!

Cheers,
Matt

RadMaskedTextBox allow Users to insert data when editing

Hi,

I'm having trouble with the edit functionality of the RadmaskedTextBox. We have a masked textbox for phone numbers with the following mask: "(##) #### ####" where the area code is in the brackets, followed by the actual number.

The problem is that when this textbox is populated with data from the database, sometimes the phone number does not have the area code, so it appears like this: (12) 1234 12__. When the textbox is selected and the caret placed at the start of the text, instead of inserting the missing area code at the start, it over-writes the existing data.

I have tried setting the textbox mask to be "##########" and the displayMask to be "(##) #### ####", but it still pads out the missing characters and over-writes the data when edited.

Is there a way of doing this? Or should we just go back to using standard textboxes?

Hi, I had version Q2 2011 WinForms VISUAL Style Builder, and change to the NEW VERSION OF Q3 2011, but there were some problems with DropDownButton because I can not change the properties of the button or save the changes. This problem only happens with this element (DropDownButton). How can I solve the problem?
