I've set WrapText = true on my column. It works fine in read mode, but when I go to edit the value, the wrapping is lost and makes the it very difficult to edit the value of the cell.

Grouping/Sorting changes GridView row number, but not DataSource's

I've got an app that does the following:

1) Load a DataTable with info
2) Attach the DataTable to the RadGridView
3) Runs a threaded, long process using a BackgroundWorker object.
4) Since it's using a separate thread, I update the rows with new information via the DataTable object using the row number as my identifier to know which row needs updating.

This is all fine until the GridView is grouped. If I group, then run the same process, the row number for the GridView has changed, but not for the DataTable object. How can I get them the same so I know which row to update?

}

private void button1_Click(object sender, EventArgs e)

// return;

//}

HslColor baseColor = HslColor.FromColor(Color.FromArgb(250, 0, 0));

Issue with combobox in AutoCompleteMode Append

Hello
I added a RadComboBox to a WinForm with AutoCompleteMode = AutoCompleteMode.Append. In the SelectedIndexChanged Event I have this Code:

    
            Console.WriteLine(radComboBox1.SelectedValue);

In the Form_Load method I have this:

    
            IList<MyObject> orte = new List<MyObject>();     
        
            orte.Add(new MyObject(1, "aaa"));     
        
            orte.Add(new MyObject(2, "bbb"));     
        
            orte.Add(new MyObject(3, "bbb"));     
        
            radComboBox1.DisplayMember = "Ort";     
        
            radComboBox1.ValueMember = "Id";     
        
            radComboBox1.DataSource = orte;

I start the application, then I select the second bbb entry with the mouse. Then I press the tabulator key. The combobox then will select the first bbb (SelectedValue is 2). In AutoCompleteMode None it works fine.
Is there a workaround for this?
Thank you

SelectedIndexChanged

Hi:

I have a GridView with 2 columns (uniquenames = col1 and col2)
col1 is a ComboBoxColumn with 2 dropdown items.
col2 is a textboxColumn.

What I want to accomplish is this:
Whenever a user selects the first item from the combobox (col1), I want one set of text (e.g.: "You have selected the first item for row n") to show up on col2 for that row. Similarly, when user selects the second item from the combobox, I want another set of text to show up in col2 (e.g.: "You have slsected the second item for row n").

How to accomplish this? I have not a clue. Have searched the site for 2 hours. Saw a couple of threads that are somewhat close to what I want, but couldn't modify the codes presented on those threads to do what I want.

Your help is really appreciated. Thanks so much!

Drag and Drop Problem - View out of sync with bound Datatable

Dear Telerik Users

I'm having a problem with drag and drop functionality in a hierarchical Gridview.
As I drag rows and drop them on top of another row, the underlying (datasource-bound) datatable-entries get updated (Datarow["ParentId"] = dropCell["ParentId"].
This means, that after dragging, the entries appear under another parent in hierarchy. The gridview has to reflect these changes in the underlying database by adjusting the size of the expanded hierarchy-grid.
Even thought in general it's working, but there are a lot of incoherencies,
- expand/collapse is running out of sync
- parents with children sometimes cannot be expanded
- the children of the last row in the mastertemplate never shows the children even though expanded (children are "hidden")

closing and reopening the gridview solves the out-of-sync issues until I restart drag and dropping + expanding and collapsing

Question:
What is the "official way" of keeping the underlying datatables and the visual elements syncronized?
I've tried:
1. Datatable.AcceptChanges()
2. DataRow.BeginEdit() - EndEdit()
3. dropTemplate.Update(GridUINotifyAction.... ==> every action)
4. RadGridView.Update() RadGridview.Refresh()
The only effect I've noticed is that the "GridUINotifyAction.AddRows" seems to adapt the size of the expanding parent.

Sorry, maybe it's a trival mistake, but I do not see it and I'm almost there...

Thank you.

Markus

TextImageRelation of TabItem

Hello,

I have a problem with the properties TextImageRelation.
I'm using VisualStudio 2005 and the latest version of TabStrip.
I have a TabStrip with TabsPosition set to Top, and in the only TabItem I have an image and a text. If I change the TextImageRelation in a value different from ImageBeforeText (default) it will not be saved in the designer and if I close and reopen the form I will find the properties resetted to its original value ImageBeforeText.

This problem occour also when I change the TabsPosition to Left (this is the layout I need) but the default value of the TextImageRelation is TextBeforeImage and I cannot change it for the same reason.

I have the same problem with the properties AngleTrasform of the ImagePrimitive of the TabItem, cause when TabsPosition is set to left the icon appear flipped horizzontally

Probably I could solve all the problem by code, but I prefer a solution in the designer

Thanks a lot
