Inability to set the ComboBox.SelectedValue when ToolWindow.DockState = AutoHide

Hi,

I'm using VS2010 with Q3 (2010.3.10.1215) in Win7.

I'm having issues with being able to set the SelectedValue of a ComboBox (standard windows forms control) that was created and added to a ToolWindow while the ToolWindow.DockState = AutoHide. When the DockState is Dockable, the value can be set without issues.

I have 2 ToolWindows: ToolWindow1 contains a RadTreeView and ToolWindow2 contains various controls (ComboBoxes, TextBoxes, etc). Depending on the node the user selects certain controls are created, added to the ToolWindow and then the values set. This works fine if ToolWindow2 isn't in AutoHide when the user selects a different node. If the user AutoHides ToolWindow2 and then changes nodes, the SelectedValue for the combobox remains null. However, the text value of the textboxes can be set regardless of the DockState.

Note: If I use the SelectedIndex instead of SelectedValue I get an ArgumentOutOfRangeException when the ToolWindow.DockState = AutoHide even though the DataSource of the ComboBox is not null and has more than enough rows for the chosen Index.

I am currently using a work around by using the the AutoHideWindowDisplayed event which calls the RadTreeView_SelectedNodeChanged event. Unfortunately, this isn't ideal because the ToolWindow2 starts off empty for a split second then suddenly the controls appear. I have tried the AutoHideWindowDisplaying event, however this did not change the stated behaviour; the SelectedValue of the ComboBoxes remained null;

Any ideas?

Kind Regards

RAD Demo Carousel values

Hi,
I want to create a Carousel just like in the rad demo main application when i clicked any header from the left menu not in the any example of Carousel menu. (Open the demo, click the Carousel menu. You will see a Carousel with three images). I can't create a Carousel like that. Can you send me Center, U, V, initialangle, finalangle,zscale etc. values?
Thanks.

Problem Changing Sorted Column

Hi All,

I have a RadGridView with only about 40 rows and about 15 columns. I am sorting by two of these columns, "Presented" and "Number". At some interval, I loop through the entire grid and set the "Presented" value for each row to 0, which of course will change the sot order of the grid (because I am sorting by "Presented", which I have just changed to 0). It seems that when this happens, some of the rows never get iterated over because they have been moved in the rows collection - due to sorting. I have pasted my code below ... should I iterate and change the call values some other way?

I first tried this:

foreach (GridViewRowInfo dr in grdHuntGroups.Rows)

{

dr.Cells["Presented"].Value = 0;

dr.Cells["Handled"].Value = 0;

dr.Cells["Voicemail"].Value = 0;

dr.Cells["Abandoned"].Value = 0;

dr.Cells["Overflowed"].Value = 0;

}

And have since tried this:

for (int i = 0; i < grdHuntGroups.Rows.Count; i++)

{

grdHuntGroups.Rows[i].Cells["Presented"].Value = 0;

grdHuntGroups.Rows[i].Cells["Handled"].Value = 0;

grdHuntGroups.Rows[i].Cells["Voicemail"].Value = 0;

grdHuntGroups.Rows[i].Cells["Abandoned"].Value = 0;

grdHuntGroups.Rows[i].Cells["Overflowed"].Value = 0;

}

Thank You!!

Conditional Formatting + selected Row = trouble with color

Hi,

I am using the GridView with Conditional Formatting.
I set the RowForeColor and the CellForeColor and it works great.
I´m using the colors: black, red and green.

The Grid looks great. But when I select a row the ForeColor does not change, like a "normal" row, without Conditional Formatting does.
The selected row has a blue BackColor with green ForeColor. And this is hard to read for the user.

How can I handle this?

regards

Strange Issue with a custom Column: custom CellType appears in incorrect cells

Greetings!

I'd love to know if there's a problem with my code or if this is some kind of bug in the GridView, as the result is very strange.

If I create a custom column by inheriting GridViewDataColumn, the cell for that column will appear correctly in its own column, but will also occasionally appear in other columns.

Steps to reproduce
This is not my actual implementation, but a much simplified bit of code that reproduces the problem - the custom column here just displays a button for testing purposes.

I am running Telerik Controls for Windows Forms 2010.3.10.1215

Create a form called "ManualBuildTest" with a RadGridView on it, called "Grid" (Dock: Fill). Then use the following code in the form:

public partial class ManualBuildTest : Form

{

public ManualBuildTest()

{

InitializeComponent();

}

private void ManualBuildTest_Load(object sender, EventArgs e)

{

var col1 = new DataLinkColumn(string.Empty);

col1.AllowGroup = true;

col1.HeaderText = "Requested By";

Grid.Columns.Add(col1);

var col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Position";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Organisation";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = false;

col.ReadOnly = false;

col.HeaderText = "Work Phone";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = false;

col.ReadOnly = false;

col.HeaderText = "Mobile";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = false;

col.ReadOnly = false;

col.HeaderText = "E-Mail";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = false;

col.ReadOnly = false;

col.HeaderText = "Fax";

Grid.Columns.Add(col);

var dcol = new GridViewDateTimeColumn();

dcol.AllowGroup = true;

dcol.ReadOnly = false;

dcol.HeaderText = "Date Requested";

Grid.Columns.Add(dcol);

col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Request";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Status";

Grid.Columns.Add(col);

col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Assigned To";

Grid.Columns.Add(col);

dcol = new GridViewDateTimeColumn();

dcol.AllowGroup = true;

dcol.ReadOnly = false;

dcol.HeaderText = "Request Completed";

Grid.Columns.Add(dcol);

col = new GridViewTextBoxColumn();

col.AllowGroup = true;

col.ReadOnly = false;

col.HeaderText = "Result of Request";

Grid.Columns.Add(col);

Grid.Rows.AddNew();

}

public class DataLinkColumn : GridViewDataColumn

{

public DataLinkColumn(string fieldName)

: base(fieldName)

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

return typeof(DataLinkCellElement);

return base.GetCellType(row);

}

public class DataLinkCellElement : GridDataCellElement

{

private RadButtonElement _ctlButton;

public DataLinkCellElement(GridViewColumn column, GridRowElement row)

: base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

_ctlButton = new RadButtonElement();

_ctlButton.Text = "TEST";

_ctlButton.ShowBorder = true;

Children.Add(_ctlButton);

}

protected override void SetContentCore(object value)

{

_ctlButton.Text = value == null ? "(null)" : value.ToString();

}

If you then run the form, everything (usually) looks fine at first: the custom column appears in the first column as set (the cell contains a button with the word "(null)" in it for now).

But if you make sure that the window is small enough that the Grid's horizontal scrollbar appears, and scroll back and forth, the custom button is appearing in other cells sporadically (see the attachment for an example).

I've tried to match my code to existing code examples, and even tried it with the RadRadioButtonCellElement custom column from the Knowledge Base, and got the same result.

Is there something fundamentally wrong with my code?
