node alignment

hello,

I'm creating a RadTreeView dynamically. when adding the first level (0) nodes to the treeview, the nodes that have children are aligned without any margin, while the nodes that do not have any children are aligned with a margin. all the nodes were created the same way (all the nodes are added in a loop). can anyone help me align all the the nodes in the same place?
i attached a screen shot of the RadTreeView that i get (Personal and Confirmation Center don't have any children while the others have)

thank you

GridViewDecimalColumn not sorting correctly

Hi everyone,

I am hoping someone can help me solve a problem I am having with the GridViewDecimalColumn in my radGridView. I have an unbound column named "Days". This column is populated when the grid is loaded in the following way:

private void grid_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)

{

if (e.Column.Name == "Days")

{

MyObject obj = (MyObject)e.Row.DataBoundItem;

if (obj != null)

{

TimeSpan span = DateTime.Now.Date - obj.SomeDate.Date;

e.CellElement.Value = span.Days;

}

When I try and sort on this value, the sort order does not make any sense. I get things like the following:

14
14
33
33
36
17
14 (should be at the top with the other 14's)

The sort does not follow any sort of logic and instead appears to just be sorting the numbers randomly. How can I get it to sort the numbers properly (IE ascending/descending order)

Thanks

----- EDIT-----------

Now that I have played with it a bit more, the grid is sorting, it is just sorting extremely slow. Moving the scrollbar up and down will force the grid to repaint and you can see the sort occurring. Why is this so slow? There are only around 160 rows in this grid. I have sorted other grids with 200+ rows and the sort is instantaneous.

Row 0 is always selected

DISREGUARD: I found the error and it was in another method that for some reason was coded to alwyas select the last row.

When ever my form is loaded with a radgirdview control on it the row 0 is always selected. The grid is a multiselect and It is set so the user can select multiple rows and then click a button and all rows that are selected will be updated.

On the form load I have this code

POSSGridView.ClearSelection();

POSSGridView.CurrentRow = null;

and I loop through the rows as follows

foreach (GridViewRowInfo rowInfo in POSSGridView.Rows)

{

if (rowInfo.IsSelected)

The issue is when the form loads if I hit the button the .SelectedRows has row 0 in it. If I select it and then select another row and hit the button not eh .SelectedRows has both rows as being selected even though on the screen the 0 row is not selected. I am unalbe to find anyway to not have the 0 row selected.

[Solved] Row Reorder Event

Is there any way to catch a row reorder event?

My grid is in unbound mode, with AllowRowReorder = true. I need to be able to tell when a user reorders the rows via drag and drop, but the obvious DragDrop event is not hit. Do I really need to use MouseDown, MouseUp, and lots of calculations of row size and position?

-----------------------------------------------------------

Since posting this I found my answer in your demo:

...

 this.radGridView1.Rows.CollectionChanged += new NotifyCollectionChangedEventHandler(Rows_CollectionChanged);

...

 private void Rows_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
        {
            if (e.Action == NotifyCollectionChangedAction.Move)
            {
                for (int i = 0; i < this.radGridView1.Rows.Count; i++)
                {
                    this.radGridView1.Rows[i].Cells["Priority"].Value = i + 1;
                }
            }
        }

[Solved] change text in the cell

When I'm changing text in textbox - the value in the cell is changing too(at the same time). I use event

private void rtx_TextChanging(object sender, TextChangingEventArgs e)

{

RadTextBox rtb = sender as RadTextBox;

string title = rtb.Name.Substring(0, rtb.Name.Length - "textbox".Length);

this.radLabelElement1.Text = rgv.CurrentRow.Cells[title].Value.GetType().ToString();

rgv.CurrentRow.Cells[title].Value = e.NewValue;

rgv.CurrentRow.InvalidateRow();

}

where rtx - radtextbox

What event? I need to use to do the same thing for textboxes - when I change value in the cell the value in textbox changes too. I was trying to use CellValueChanged but it affects only after I press enter

[Solved] Radgrid cell formatting problem

Hi Telerik,
I have assigned some cols as read only in the radgrid(radform) and i used cell formatting to apply colors like this by name:

DTURradGridView.Columns["dtuct0"].ReadOnly = true;

DTURradGridView.Columns["dtuct1"].ReadOnly = true;

DTURradGridView.Columns["dtuct2"].ReadOnly = true;

DTURradGridView.Columns["dtuct3"].ReadOnly = true;

DTURradGridView.Columns["dtuy"].ReadOnly = true;

if (e.CellElement.ColumnInfo is GridViewDataColumn)

{

if (e.CellElement.ColumnInfo.FieldName == "dtuct0" )

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct1")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct2")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct3")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuy")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

Then i want to hide/unhide based on the selection like this:

private void normalToolStripMenuItem_Click(object sender, EventArgs e)//Normal View

{

DTURradGridView.Columns["dtuct0"].IsVisible = false;

DTURradGridView.Columns["dtuct1"].IsVisible = false;

DTURradGridView.Columns["dtuct2"].IsVisible = false;

DTURradGridView.Columns["dtuct3"].IsVisible = false;

DTURradGridView.Columns["dtuy"].IsVisible = false;

}

private void advancedToolStripMenuItem_Click(object sender, EventArgs e) //Advanced View

{

DTURradGridView.Columns["dtuct0"].IsVisible = true;

DTURradGridView.Columns["dtuct1"].IsVisible = true;

DTURradGridView.Columns["dtuct2"].IsVisible = true;

DTURradGridView.Columns["dtuct3"].IsVisible = true;

DTURradGridView.Columns["dtuy"].IsVisible = true;

}

When i Click on Normal Mode function, it applies colors to other cols. This is really strange for me. Please help me, thank you.

Invoking of collectioneditor for property value in RadPropertyGrid

Hi,

We are trying to replace a winform propertygrid with a RadPropertyGrid.

Previously, we were binding an object to the property grid, which in turn was displaying all the properties. If one of the properties is a collection it used be displayed in a collectioneditor when invoked from the property value.

Since the Propertygrid is replaced by RadPropertyGrid, we have been unable to do this. Even when one of the properties is returning a collection it the property grid is not providing the means to invoke the collection editor. I feel like we are missing something.

Thanks in advance
