[Solved] Update of text/value on NewRow at CellEndEdit event does not reflect changes

Dear Telerik team,

I have an event handle on the RadGridView.CellEndEdit event;

Its purpose is to look up a value from the database by the value entered in that cell and overwrite it with the value returned from the database.

Scenario and implementation:

User creates a new row in the grid and enters 'ABC' as value for the 1st column//cell. Then they press ENTER which will cause the radGridView1_CellEndEdit to be invoked.

private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
{
    int rowIndex = e.RowIndex; //is -1, since it's a new row
    int columnIndex = e.ColumnIndex; //is 0, since it's the 1st column that's being editited by the user.
    GridViewRowInfo row = this.radGridView1.MasterGridViewInfo.CurrentRow; //The only way to get the row (since rowindex => -1)
    string cellText = row.Cells[0].CellElement.Text; //is 'ABC', as entered by the user
    string cellValue = (string)row.Cells[0].Value; /is <Null> ??????
    row.Cells[0].Text = string.Join(",", new string[] { cellText, cellText }); //Concatenats into 'ABC,ABC' and overwites the cells text with that.
}

Now when you look at the cell on screen, you'll see that it still presenting it as 'ABC'.

Remarks.
1) Setting the Cell value does not help in any way.
2) The code above does work if the row is not a new row.
3) If the grid is under VirtualMode = true, then NO text can be read from that cell in the snippet.

I would like to know what is there to do to have the value/text being overwitten on CellEndEdit' in case of a NEW row. It's a key requirement for the application I'm working on.

Kind regards,

Jack

Can't find TypeConverter

Hi,

I use the DockingManager in my project.
The line

Me.DockingManager = New Telerik.WinControls.Docking.DockingManager

causes about 20 MessageBoxes to pop up saying "Can't find TypeConverter to string for animation step of type Telerik.WinControls.ColorAnimationStep"
After that everything seems to be working fine.
This happens only on machines where Telerik is not installed. Machines with RadControlsWinforms_Q3_2007 don't show any MessageBoxes.

I hope you can give me any advice,

Thanks,
Chris

Update WinForms Installer

I've seen how beautiful the AJAX suite installer has been over the past releases. It looks so cool! I would like it if all of your product suites (or at least WinForms, to start!) used such gorgeous installer templates. If it's not already something in your roadmap, I would definitely consider it. Installing programs is a really mundane task, and enhancing the UX during that stage would be great.

Regards,

Inheriting RadComboBox

Azdravei (and apologies for mangling your words),

I am trying to inherit from the RadComboBox in my winform project. For starters, I simply created a class that inherited the RadComboBox and placed an instance of it on a form, right next to the original, uninherited RadComboBox. The two controls look radically different, with my inherited version looking like a broken misfit unworthy of the name Telerik.

I would like to know how to properly inherit and extend Rad controls. In my case, I simply want to add a field and property to the ComboBox to remember its previous SelectedIndex.

Thank you,
Guillaume

[Solved] Dragging Panel off to New Window

I have a C# WinForm demo that is based on a Shaped Form with a Docking Manager on it and a few Docking Panels. If I drag a Docking Panel out of the form to create a new window, the new form appears to be a Windows Form. Is there a way to have the new window be created as a Shaped Form with the same style as the one the Docking Panel came from?

Update problems

Hi :o)

I am having a strange problem when updating new added records in the grid.

I use the code below to cycle through the grid and change the ClientId to p_ClientId which works fine. This is why the msgbox is there to check the value which changes to the value in p_ClientId as expected. You can also see this reflected in the grid itself as the column is visible.

For i = 0 To Me.RadGridView1.RowCount - 1

Me.RadGridView1.Rows(i).Cells("ClientId").Value = p_ClientId

MsgBox(Me.RadGridView1.Rows(i).Cells("ClientId").Value)

Me.ClientsSupportRequiredBindingSource.EndEdit()

Me.ClientsSupportRequiredTableAdapter.Update(Me.Clients)

The database only reflects the change in the last record. The others are added with a NULL in ClientId. This only affect this one field and only when adding a new record. If you update other fields directly using the grid then they update correctly.

Thank you so much for your help

[Solved] Scaling & Zooming Demo

Hi

In the scaling and zooming demo the controls display a popup. How would I make something similar but which allows editing? I'm after something like the toolbar in Word2007 that appears semi-transparent but then goes solid and allows interaction when I move my mouse over it.

Thanks

Sean
