Hi

I'm trying to use a telerik RadRichTextBox for my windows form. Is there a way I can remove the cursor from the control after inserting the value using the following line:

RADRichTextBox1.Insert('xxx')

RADRichTextBox2.Insert('yyyy')

Please see the attachment for reference.

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

Hi, I need to program the following:

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. :)

RedDataGridView and Grouping in Virual Mode

Hello,
I have problem with grouping in the RadDataGridView. In my project the grid must be in the virtual mode: (VirtualMode = true) (filling some cells are taken from a list; FieldName property cannot be used), but grouping by some parameter (in the grid) is not working in this mode, since Grouping property is joined with bindingSource controller, which I cannot use (If I understood well the functionality). Thus, it is possible to group data in the virtual mode? If it does, could someone attache a piece of code for me?
Thank.

Limiting Entry to values contained in ComboBox

Hello,

We are using a MultiColumn ComboBox for a drop down list in our app.

I'd like the user to only be able to enter values that are contained in the list.

Currently, they can type anything they like in the box, and save it.

Of course, they can also use their mouse to select an item, but we'd like to prevent them from saving invalid data.

Thanks,

How to seach for text in a column

Is there a simple way to search a column for a specified text and then select the first (then next) row with the text, if found?

(I am aware of the Filter functionality, but that is not what I need here.)

I'm having a hard time adjusting to the object model of the RadGrid, being used to such simple things as MSFlexGrid.TextMatrix(iRow, iCol).

Can you point me to a grahic view of the RadGrid object model?
