Hi,

In debug mode I am stepping thru the code in visual studio. The problem is that the expanded part of the ribbon sits on top of the visual studio screen thereby hiding the code. This is not a big deal but annoying, I am running with the latest libraries.

Thanks
Rich

Don't allow to end edit mode with key left or right

I'm using Winforms Q2 2011 SP1.
The gridview cell is in edit mode and the text cursor is at the right/left bound of the text editor.
How can I avoid that on the next right / left key the editor is closed an the next cell is selected.

Bind to DataView

Is it possible to bind the scheduler to a DataView? I have a lot of code on another form that uses a datagrid to show appointments. I've already written my filtering based on many relational tables and I would like to reuse it. My appointments have many resource tables (Type, Location, Employees, Guests, Units, Groups) and I would love to not have to write a lot of stored procedures. I also like the instant filtering given by using a DavaView without having to refill the data.

Multiple Select Checkbox with custom Text behavior

I am having difficulty finding the right circumstances to create the following:

I need a drop down list with check boxes for each item.
Each item in the drop down displays a human readable string, but has a char value
Each time an item is checked, the Text value must be a concatenation of each selected char value
Each time the Text is edited, each individual letter in the Text field must check the DropDown item with the matching char value.

_________
- 1 - First Item
- 2 - Second Item

1________
x 1 - First Item
- 2 -Second Item

2________
- 1 - First Item
x 2 - Second Item

12_______
x 1 - First Item
x 2 - Second Item

In each of the above crude examples, the value of each item in the list would be 1 and 2.

I tried implementing the example code you provide in your RadControls Demo application, following the DropDown & List/Creating New Items example, and I am therefore able to get multiple checkboxes to display. (It appears your source code in the RadControls Demo is missing the "this.radDropDownList1.CreatingVisualListItem += this.CreatingVisualListItem;" for the list and dropdownlist objects.)

However, I need a few more things I have not been able to find in the forum notes:

1) I need to keep the drop down from closing when checkboxes are selected.
2) I need to set the Text object of the list to a custom value (concatenation of the values of the checked items).
3) I need the reverse, setting the checkboxes based on what is typed in the field
4) I need to insert an OK button in the drop down to allow the user to close it when they are done checking boxes.

Any thoughts?

Thanks

Hide Form Title Bar

Hi,

I changed the form property FormBorderStyle = None. That hides the border but the user can't resize the window other than go to full screen. I also blanked out the forms text property and set the controlbox property to false. In the controls RadRibbon demo the form title bar is hidden but the form can still be resized by the user. How was that done??? I saw mention of RadForm and RadFormShaped on old forum threads but I assume they have been depreciated. I am using Telerik Q3 2012 assembly V4.0.30319.

Thanks
Rich

Search radtreeview nodes

Hi,
other question... I was trying to build a search for my treeview. But with some examples of the net for a normal treeview, I don't get it working.

Here is my code:

RadTreeNode[] tn = rtrvNetworkAll.Nodes[0].Nodes.Find(txtSearch.Text, true);
for (int i = 0; i < tn.Length; i++)
{
         rtrvNetworkAll.SelectedNode = tn[i];
         rtrvNetworkAll.Select();
         rtrvNetworkAll.Focus();
}

So there are nodes that can have the same name.

I searched in the support contents of the radtreeview. Found nothing yet.

Thanks in advanced

items.add for ComboBox

I'm not able to find a working example of what I need. They are either outdated and not compatible with 2012 Q3 or they don't apply.

I need the Telerik version of

Dim GuestCB As DataGridViewComboBoxCell

GuestCB = DataGridView1.Rows(DataGridView1.RowCount - 1).Cells("Guests")

For Each RV2 As DataRowView In DV2

Dim Row2 As DataRow = RV2.Row

GuestCB.Items.Add(DVGuests.Table.Rows(DVGuests.Find(Row2(2)))("LookupName"))

Next

DV2 is a filtered DataView that changes with each row, that's why I fill the ComboBox manually. This is just for display purposes - nothing is selected.

ProgressBar does not update untill after work is done!

Hi, I have an import feature that I want to display progress while its running.
the import feature is located in a MdiChild
the progress bar is located in a radStatusStrip on the Parent form

here is the code I have and yet the Progress bar doesn't move untill after the loop is done.

int j = Textbox_InputText.Lines.Length;
(ss.Items[1] as RadProgressBarElement).Maximum = j;
int i;
            for (i = 0; i < j; i++)
            {
                ....Do import stuff

                //I tried .Value++ also and same results
                //(ss.Items[1] as RadProgressBarElement).Value1++;
                (ss.Items[1] as RadProgressBarElement).PerformStepValue1();



            }

PLEASE Help, I am extremely frustrated with this.

CreateNode event not fired

AllowAdd = true;

When I right-click a node and choose "New", I want to make sure that the Tag of RadTreeNode is set to some important data. I'd expect the CreateNode event to solve this:

private void radTreeView_CreateNode(object sender, CreateTreeNodeEventArgs e)
{
e.Node.Tag = obj;
}

However, this event is not called when I choose "New". Is this a bug or a feature?

Images not updated until scrolling

I'm adding all my nodes in the NodesNeeded event. Then, in the NodeFormatting event, I'm changing the image of the nodes using the ImageKey.

The problem is that NodeFormatting is not called for all visible nodes. It seems it gets called for arbitrary root nodes when I expand one of the roots or when I scroll up and down. What's going on?

UPDATE
If I explicitly set the ImageKey when adding the nodes (which I don't want to do), then all images are updated when I click inside the tree view. Calling Refresh() after adding the nodes does not help.

UPDATE 2
Another problem... when I double-click node A its icon changes to "Open" and is kept open until I select one of its child nodes. When a child is selected, the icon changes to "Closed". I have put breakpoints at all places where I set the icon to "Closed" and it does not fire. Hence, for some reason, the RadTreeView manages to revert the icon to its previous state...
