Maximum row height with AutoSize

Hi,

I'm trying to set the maximum height of a row, but it doesn't work... I've enabled the AutoSizeRows property.

private void Grid_RowFormatting(object sender, RowFormattingEventArgs e)

{

// Current -> e.RowElement.RowInfo = 64

e.RowElement.RowInfo.MaxHeight = 32;

}

Thanks,

Changing cell value causes a blank cell

I'm writing an application which iterates through the rows of an unbound RadGridView and changes the value and formatting of a particular cell as it goes. I'm having no issue iterating through the rows, but when I get to the point of calling for a cell's value or formatting to change the cell empties of all visible data instead.

The way I'm iterating through the cells and changing the value is like so:

foreach (GridViewRowInfo row In rgvFiles.Rows)

{

row.Cells[2].Value = "New Text";

row.Cells[2].Style.BackColor = Color.DarkGreen;

row.Cells[2].Style.ForeColor = Color.White;

}

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?
