I created a custom combobox that I want to use in the grid view during editing.  When the user is editing the data I want to allow then to beable to choose from a list of items, enter in new items (like a text box and save when done typing or lost focus) and also allow the user to click on an x next to an item and remove it from the list items.  Is this possible?  So, is it possible to customize the list itmes to have a image (x) and use a click event on the fire a method to delte the item?

"object reference not set"  and my application is terminated.

Hi,

I would like to be able to prevent the user to change the value on certain situations but I cannot find an event that would help me do that.

I've found the MultiColumnComboBoxElement.TextChanging event, but that only works when the modification is made with the keyboard. I would need to be able to handle also the modifications made by the mouse, including the mouse wheel.

Any ideas?

Thanks!

When the user has added a new row in my grid the column values are written to the database.

In the UserAddingRow event I ask the user "Are you sure you want to add values to database?", and I set e.Cancel=true in case the answer is no.

If the user starts adding values in the grid, and then changes his/her mind and try to close the application, this question from the UserAddingRow event fires, which is not how I want it to be. If the user wants to close the application, the application should close.

I've tried capturing the FormClosing event to set applicationClosing=true and add a check to this in the UserAddingRow event, but the FormClosing event fires after the UserAddingRow, so there is no help there.

Is there another way to prevent the UserAddingRow to be handled when the form is closing?

Hi,

We are developing a new GUI to our system, which is built on top of a legacy code. In details, we write our User Control as a COM (CCW) object that contains the RadGridView and is then placed in the old GUI. The GridView should act mostly in read only mode. Since the communication between the old system and the new system is through the COM interface - it led us to choose the XML populating method to populate our grid. We've sent the XML as a string to the user control. It worked perfectly when we needed only text to be shown in the grid.

Now, we need to be able to show several types of data and several sub-controls in the grid cells (i.e.: GridViewComboBoxColumn, GridViewCheckBoxColumn, GridViewDecimalColumn, GridViewDateTimeColumn, GridViewImageColumn). The way it works now is:
(a) Loading the XML into a source DataTable, using ReadXml
(b) Building a new target DataTable with the needed data types
(c) Adding the right data columns to the Grid
(d) Iterating through the source DataTable and copying each cell to the target DataTable
(e) Assigning the target DataTable to the grid as its Data Source.

As expected - this process led to performance issues...

So, we would like to know if our solution is correct? Is there another way to populate the grid under our limitations?
(Even if we bypass the process of building the XML in the legacy system, and accessing the DB directly, we still need to iterate through all the cells and copying them)

Thanks,

Hi,

I am currently working with the radRichTextBox control to format plain text.

I must replace certain keywords such as <%sender%>, with the text 'You', and then format this in bold font. 

I am able to add additional text to the RTB, however it is added at the end.  

Please help
