Wrong number of nodes in SelectedNodes.

Hi,

Create new form and paste code below.
Run form, expand "root" node and select any item. SelectedNodeChanged event should write to console value "1".
Then click button to rebuild re-build the tree, again expand "root" node and select any item.
This time SelectedNodeChanged will write to console value: "2".

private void Form1_Load(object sender, EventArgs e)

{

RadButton b = new RadButton();

b.Text = "Rebuild";

b.Dock = DockStyle.Top;

b.Click += b_Click;

rtv = new RadTreeView();

rtv.SelectedNodeChanged += rtv_SelectedNodeChanged;

rtv.Dock = DockStyle.Bottom;

this.Controls.Add(b);

this.Controls.Add(rtv);

Rebuild(rtv);

}

RadTreeView rtv = new RadTreeView();

private void rtv_SelectedNodeChanged(object sender, RadTreeViewEventArgs e)

{

Console.WriteLine(rtv.SelectedNodes.Count);

}

private void b_Click(object sender, EventArgs e)

{

Rebuild(rtv);

}

private void Rebuild(RadTreeView rtv)

{

rtv.Nodes.Clear();

rtv.Nodes.Add("root");

rtv.Nodes[0].Nodes.Add("level 1 item 1");

rtv.Nodes[0].Nodes.Add("level 1 item 2");

rtv.Nodes[0].Nodes.Add("level 1 item 3");

rtv.Nodes[0].Nodes.Add("level 1 item 4");

// this don't work

rtv.SelectedNodes.Clear();

}

Radbuttonelement Alignment

I just updated my project to Q1 2009. The buttons in my RadRibbon are displayed as an icon centered above text.

After the upgrade, the icon is no longer centered, but left-aligned over the text.

Why has the behavior changed, and what do I need to do to get my alignment back where it belongs?

Exponential values

Hi,

in a form, I Need to use a TextBox to enter values in the exponential form. In Radform's textboxes, there's no possibility to directly validate the Input or to Format it like ##.##e##. Is there a way to do this by radform or do I Need to write my own Input Validation and formatting?

Overflow area

Hi, I want to save the state of the page view and restore it when a user logs back in.

I am trying to find out how to;

1) inspect the pageviews and determine if they are a) in the overflow area and if so b) is their button visible or hidden.

2) set the pageviews back to the state they were at in the overflow area and whether the button is hidden

Thanks,

RadGridView (RowValidating Event)

Hi,

I am having trouble using the RadGridView (RowValidating Event).

When the RowValidating is fired, the values of my new row to be added are checked,
if one of them is not okay, the message is shown to remind the user to input the correct values.

The problem is:
- if I don´t want to add this new row, how do I discard it?
(in the case I have all cells, for this new row, with null values)

I have the "e. Row. Cancel = true" to try to cancel de adding, and it works,
but the problem is that the phrase "Click here to add a new row" is not set
back to the top, and any other values (Cells) that is in the grid can´t be edited,
it got stuck, until I finish adding this row.

If I erase my "RowValidating" and try again, the problem is solved.

Is it possible to discard a new row
if I have a "RowValidating" on, and once it´s canceled,
to have the phrase "Click here to add a new row" back on top to start over a new adding?

Thanks for your help.

BorderStyleDash Issue

I am trying to put a dotted border around the selected row. It seems that if I choose "SingleBorder" with element state GridDataRowElement.IsSelected.IsCurrent.HotTracking, the border does not appear until to row is selected a second time. If I choose "FourBorders" it works fine but I always get a solid border when BorderDashStyle is set to anything other than solid. It does not appear that you can use the BorderDashStyle with "FourBorders" selected - only "SingleBorder" works with BorderDashStyle. Any thoughts?
