Hi, I've been working with Telerik controls for about 6 months.

I am having an issue where I have a RadGridView with a GridViewComboBoxColumn.  The GridViewComboBoxColumn is populated with a list of companies and the RadGridView is populated with a list of employees. 

If an employee has just been created in the system, they have default "N/A" company assigned to them until it is assigned to them using the RadGridView employees screen I am creating.  So I can have a RadGridView with 500 rows of employees and each has an "N/A" Company assigned to them. 

The issue I am having is, when I am editing the employees in the RadGridView with the GridViewComboBoxColumn, when I select a company for one employee, ALL the other rows that have "N/A" company assigned to them change to that combo box selection as well.


The above code shows that COMP is a company object that belongs to the EMPLOYEE Object.  The field name is the Id property of the Company.   "_job" is just a class that Populates and IList<T> of objects from the database and returns them to the form.

So if the employee had a default "N/A" company assigned to them the COMP.Id value would be 111.  So all new employees without a company, will actually have a default company assigned to them and that will be company Id 111, and CompanyName of "N/A".

I am attaching two screen shots of the grid which I hope will help explain the problem a little better.  This is kind of a difficult question to explain.

Thanks.

Hello Telerik Team,

I'm using 2010.1 409 Winform Telerik library on both VStudio 2005 and VStudio 2008.

I'm trying to implement a (rad)gridview in Virtual Mode using more than 150000 records/table.

Moving across the first 1000 records is very flawless.
Instead, if I try to scroll to the last records, the grid significantly slow down.

The following code should reproduce the problem:

The standard C# DataGridView, with the same code, works without any problem.

Thanks in advance.

I'm using RadGridView in unbound mode. I've added a GridViewComboBoxColumn (bounded) at design time.
Now I want to fill that grid with the data from a database table. I'm using the RadGridView.Rows.AddNew()  
method. When I try to set the value of this column using RadGridView.Rows[index].value i generate an exception
objec reference not set. What is the solution o tthis problem?

The previous value of the column is 3000 then after I changed it to 3 then CellValueChanged is fired but then the string quantity does not return 3 but instead 3000. I will be using the new value to update the record on the database.



The datasource comes from a result of a LINQ query, I need to update at database level using this event. If I am not using the right event please direct me to the right event. This event fires up after editing the field and clicking outside the field BUT it does not return the new value but the old value. Please tell me if you need more information, this is kind of urgent.

After clicking outside the cell the value reverts to the old value hence the CellValueChanged event gets the old value. What should I do to commit the new value to the Grid Row and to retrieve the new value for database updating?

Our WinForms application loads some assemblies into the Load and LoadFrom contexts. Some RadButtons are used by assemblies in each group, so we also load Telerik.WinControls.dll into both contexts.  However when we do this, some machines receive an error when opening the main form.  It appears that a telerik library is popping the dialog with the following text:

Visual Studio is attempting to load class instances from a different assembly than the original used to create your components.  This will result in failure to load your designed component.  More information that will help you to correct the problem.

Component Assembly:
D:\Documents and Settings\09006318\Local Settings\Application Data\Test App\Assemblies\Telerik.WinControls.dll

Designer Assembly:
C:\Program Files\Test App\Telerik.WinControls.dll

Please Close Visual Studio, remove the errant assembly and try loading your designer again.

Ensure that you do not attempt to save any designer that opens with errors, as this can result in loss of work.  Note that you may receive this message multiple times, once for each component instance in your designer.

Of course Visual Studio is not installed on any of the machines with this problem.  If we only load the Telerik libraries into the Load context, the error disappears.  What is causing this error?

How do you modify the contents of the context menu in the bottome right corner of the radpanelbar?  I want to remove the Nav pane option item but I cannot figure out where to modify the items for that menu.

Is there a way to control the border of the radgridview itself?  I want to have a thicker border around the control.

Thank You
