Hello,

I have a RadTextBoxElement within a RadToolStripItem. When a specific button is pressed I want the text box to receive focus, but the focus method returns false (and doesn't do anything).
I have tried setting CanFocus, Enabled and Visibility to true and visible but the focus method still doesn't work. Any ideas on how to make it work?

RadGridViewExcelExporter with formatting / filtering + VirtualMode

Hello!
Many of my users would like to export formatted / filtered data from a datagrid and into Excel. Is there any way of solving this?

Does the datagrid support VirtualMode? I could not find any property similar to this. Or any event similar to the default DataGridViews's CellValueNeeded.

If it is not possible in this version, I would like to send a request for it.

RadGridView Q1-2008 Sp1 Column missing

Greetings:

Before Q1-2008 SP1 I loaded my radGridView with a DataSet in the DataSource property. After Q1-2008 SP1 that throws a low-level error. So, I started loading the grid via the 'MasterGridViewTemplate.LoadFrom' method.

It works except that the columns I previously added manually through code, including an additional Command column, are now replaced by the columns from the DataReader being passed to the LoadFrom method. Before the LoadFrom my column count is 6 (including my Command column) and after the LoadFrom it is 5 (the number of columns in the DataSet).

QUESTION:

How can I keep the columns that I manually added ?

Please advise ASAP

Thanks,

Robb Murdock

                </CustomerIdentifying> 
        
            </Message>

Can I display this data in a hierarchical radgridview where child records/tables of "Message" can be both "Comment" tables and "CustomerIdentifyingRecord" tables?

Simply loading the xml as a dataset does not appear to be sufficient.

Is this possible with the radgridview?

Thanks

Expand a row to show a UserControl

Hi,

1. Is it possible to create a button (image button would be nice since the GridViewCommandColumn is just wrong for this, it should be a + and -) per row? I know you do not support Hierarchies but can I "infuse" a button?

2. On that button click I would like to increase the height of the Row to add a user control that will show details, pie charts, etc. This usercontrol should be as wide as the whole row (not only a cell).

I am thinking of hacking into the source code but now when Q2 is comming up... well it would be better not to have to migrate that code every time a service pack or version of the Telerik controls is released.

Thanks,
/ jorge

3. Set the shape property of the child form to RoundRectShape.
4. Open the child form from within the parent form.
5. Minimize the child form.

Notice the title does not show.

Is there any way around this issue?

Thanks.

populate a ComboBox

I am trying to populate a ComboBox with data from a access db. I have the following code that works in a normal combobox, but with the radcombobox does nothing:

    
                            Dim ComboBox1 As New Telerik.WinControls.UI.RadComboBox 
        
                            Dim cn As OleDbConnection 
        
                            Dim connString As String = ligacao 
        
                            cn = New OleDbConnection(connString) 
        
                            cn.Open() 
        
                            Dim da As New OleDb.OleDbDataAdapter(sql, cn) 
        
                            Dim ds As DataSet = New DataSet 
        
                            da.Fill(ds, "Tabela") 
        
                            With ComboBox1 
        
                                .DataSource = ds.Tables(0) 
        
                                .DisplayMember = "D1" 
        
                                .ValueMember = "D2" 
        
                            End With

Can you tell me what I have to change to make it work?

Thanks

RadGridView's Tooltip supports only text?

Hi All,

I use the RadGridView to show text that is sometimes longer than the original cell. Since the complete text does not fit into the cell I decided to show a tool tip by using the ToolTipTextNeeded event. The problem is that this event only allows me to set a text for the tool tip. The tool tip itself disappears after only 5 seconds which makes it quite unusable for my implementation.

To find out why I cannot set an AutoPopDelay for the displayed tooltip I used a bit of Reflector magic and found out that the RadToolTip class being used is internal as well as the property that holds the tool tip for the cells. This is a bit stupid because now I can't even derive my own class.

In the end I decided to force the required values into the grid by using reflection but of course this is not the best way to solve this problem.

Shouldn't the ToolTipTextNeededEventArgs expose far more properties of the original tooltip or the entire tool tip itself?

Just in case someone else is having the some problem, I'll post my ToolTipTextNeeded event handler here:

    
            private void gviAufgaben_ToolTipTextNeeded(object sender, ToolTipTextNeededEventArgs e)
 
                    {
 
                        GridDataCellElement cell = sender as GridDataCellElement;
 
                        if (cell != null)
 
                        {   
 
                            ComponentBehavior behavior = cell.ElementTree.ComponentTreeHandler.Behavior;
 
                            PropertyInfo tooltip = behavior.GetType().GetProperty("ToolTip", BindingFlags.NonPublic | BindingFlags.Instance);
 
                            object tip = tooltip.GetValue(behavior, null);              
 
                            PropertyInfo autoPopDelay = tip.GetType().GetProperty("AutoPopDelay");
 
                            autoPopDelay.SetValue(tip, 60000, null);                
 
                            e.ToolTipText = cell.Value.ToString();              
 
                        }           
 
                    }

I hope that someone can come up with a better suggestion.

Thanks,

Sebastian
