Radio button behaviour for check box

I have a check box field in my grid that I want to be mutually exclussive. That is, I want only one or zero rows to have a value of true for that check box at any point in time. I tried code that changes the check box value of every row to false, but this is very slow. So I thought I would keep a variable that stores the last row index that had a value of true for the check box field. I have (at least) one group set up for the grid. I am trying to store the current row index when the grid is first loaded using the following code:

foreach (GridViewRowInfo _row in employeesGrid.Rows)  

{  

    foreach (GridViewRowInfo _row2 in _row.Rows)  

    {  

        if (_row2.Cells["InitialAssignee"].Value != null && (bool)_row2.Cells["InitialAssignee"].Value == true)  

        {  

            curInitialAssignee = employeesGrid.Rows.IndexOf(_row2);  

        }  

    }  

}

This code assumes that there is one level of grouping. The problem is that curInitialAssignee is always set to -1. I'm not sure why I can't get the row index of _row2.

Once the above is working, I have code in the ValueChanging event that will set the value of the InitialAssignee column to false for the row that corresponds to curInitialAssignee. Followed by a line that changes curInitialAssignee to the new current row.

Also, I want to ensure that this row index remains valid even if the data is sorted differently, or a grouping is added or removed at run time.

Thanks,
Eric.

Loading Combobox... Performance Issue..

Hello..
I am trying to load RadCombobox by using the following code.

      foreach (SuperProgram superProgram in SuperPrograms)
               {
                   RadListBoxItem listitem = new RadListBoxItem();
                   listitem.Value = superProgram.ProgramMsg.MenuName;
                   listitem.Text = superProgram.ProgramMsg.MenuCaption;
                   LsvPgramAvail.Items.Add(listitem);
               }

It takes long time to load. Whereas in Microsoft's combobox the performance is very good.

Do I need any additional code??

Thanks...

TabItem visibility

Hi
I need to be able to hide and show tabs depending on various criteria. I thought it would be enough to use Visibility = ElementVisibility.Hidden, which does indeed hide the tab, but its place is not taken up by the following tab.

The functionality I need is that when tab1 is hidden, it is made invisible and for tab2 to move to the left, taking tab1's place. When making it visible again I need the tab to appear again and for tab2 to be shifted to the right.

I've tried calling PerformLayout() without success.

Please could you tell me the official way of achieving this effect.

Best regards

Marek

Changing DataSource

Hello all,
I've been trying to data bind a RadGridView to a DataSet in order to achieve hierarchical display (can I do this with a BindingList<> ?), and as soon as I try to change the DataSource and assign to it a null value or a List<> value I get this exception:
System.ArgumentException was caught
Message="The relation is not parented to the table to which this DataView points."

the code is:
(radGridView1.DataSource as DataSet).Clear();
radGridView1.AutoGenerateHierarchyFromDataSet = false;
radGridView1.DataSource = null; // or radGridView1.DataSource = new // List<MyClass>();
radGridView1.DataSource = lines;

Is it simply impossible?
