[Solved] MultiSelect and menu

Hi.

I have found an issue in RadGridView when using multiselect and menu.
What i want to do is: select multiple lines, right click on RadGridView and execute some action on each line.
Apparently no big deal, done it with this code:

namespace WindowsFormsApplication3

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private RadMenuItem mnuAdd = new RadMenuItem("Add");

private void radGridView1_ContextMenuOpening(object sender, Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)

{

e.ContextMenu.Items.Add(mnuAdd);

}

private void Form1_Load(object sender, EventArgs e)

{

mnuAdd.Click += new EventHandler(mnuAdd_Click);

radGridView1.Rows.AddNew().Tag = false;

}

void mnuAdd_Click(object sender, EventArgs e)

{

foreach (GridViewRowInfo row in radGridView1.SelectedRows)

{

row.Tag = !((bool)row.Tag);

row.Cells[0].Value = row.Tag;

}

I only drag and drop a RadGridView control to my form, changed MultiSelect property to true and added a column.
Now, when i select multi lines (or just one line) i right click and the menu show up with my menu (and others... but also no big deal). If i chose my menu, the row value change from false to true and from true for false. Simple.

The real problem is when i order the column. After that, if i select more than one row and i select my menu, it is thrown this exception:
"InvalidOperationException: Collection was modified; enumeration operation may not execute."

According my visual studio the error it is in the foreach iteration, more exactly in the "in":
foreach (GridViewRowInfo row in radGridView1.SelectedRows)

Ok... its a foreach problem. I try replace the foreach with a for statement:

for (int a = 0; a < radGridView1.SelectedRows.Count; a++)

{

radGridView1.SelectedRows[a].Tag = !((bool)radGridView1.SelectedRows[a].Tag);

radGridView1.SelectedRows[a].Cells[0].Value = radGridView1.SelectedRows[a].Tag;

}

With this solution, after i select both rows and right click and select my menu, i found out that radGridView1.SelectedRows only have one row, the one where i right click and is the only one that got changed.

Think this is one bug in RadGridView (or i am doing someting really wrong...).

I would like some help/answer.

Kind Regards,

Bruno Almeida

Can't theme some controls in new VSB

I got the latest build (dated 3/9) and while the new VSB is great, there are controls that are not listed as available for creating a theme. RadToolStrip, RadStatusStrip, RadPanel, and on and on and on. When can we expect all of the controls to be listed, or am I doing something wrong and there's already a way to get them listed and I'm missing it?

[Solved] How do the typical grid cells determine cell border color information.

I've created a custom GridViewColumn, along with a custom CellElement, inheriting from GridCommandCellElement, and by default, the GridCommandCellElement does not have DrawBorder set to true. When I set it to true, it draws a border that is a different color than, say, a GridViewTextBoxElement within the same grid. How does the GridViewTextBoxElement know to draw it's own border as the light blue color it is currently drawing it with, as opposed to the black color my custom element is being drawn with, and how can I fetch that value?

Thanks,

David
