Hi Telerik

I am building a multicolumn dropdown list in which I wish to use grouping. The grid has three columns, SecurityType, InstrumentGroup and Instrument. I want to group on SecurityType and within that grouping by InstrumentGroup so as to create a little hierarchy to act as a visual aid in selection.

If I allow manual grouping and drag the required columns to the group panel everything works fine but if I attempt to achieve the grouping programmaically the group header text for the InstrumentGroup header shows the same text as the SecurityType header.

I have attached the relevant snippet in the hope that you will have some insight into this one. Please note the commented out code was left in so you could see the other method I tried.

Regards

Grid is setup like so..

private void GenerateMComboGrids()

{

mcboInstrument.AutoSizeDropDownToBestFit = true;

mcboInstrumentComboElement = mcboInstrument.MultiColumnComboBoxElement;

mcboInstrumentComboElement.MultiColumnPopupForm.DropDownAnimationDirection = RadDirection.Left | RadDirection.Down;

mcboInstrumentComboElement.DropDownSizingMode = SizingMode.UpDownAndRightBottom;

mcboInstrumentComboElement.DropDownHeight = 100;

mcboInstrumentComboElement.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown;

mcboInstrumentComboElement.EditorControl.MasterTemplate.AutoGenerateColumns = false;

mcboInstrumentComboElement.EditorControl.ShowGroupedColumns = false;

mcboInstrumentComboElement.EditorControl.ShowRowHeaderColumn = false;

mcboInstrumentComboElement.EditorControl.EnableGrouping = true;

mcboInstrumentComboElement.EditorControl.AutoExpandGroups = true;

mcboInstrumentComboElement.EditorControl.ShowGroupPanel = false;

mcboInstrumentComboElement.RightToLeft = true;

GridViewTextBoxColumn column = new GridViewTextBoxColumn("SecurityType");

column.HeaderText = "Security Type";

mcboInstrumentComboElement.EditorControl.Columns.Add(column);

GridViewTextBoxColumn column2 = new GridViewTextBoxColumn("InstrumentGroup");

column2.HeaderText = "Instrument Group";

mcboInstrumentComboElement.EditorControl.Columns.Add(column2);

GridViewTextBoxColumn column3 = new GridViewTextBoxColumn("Instrument");

column3.HeaderText = "Instrument";

mcboInstrumentComboElement.EditorControl.Columns.Add(column3);

mcboInstrumentComboElement.EditorControl.GroupDescriptors.Expression = "SecurityType ASC; InstrumentGroup ASC";

//GroupDescriptor descriptor = new GroupDescriptor();

//descriptor.GroupNames.Add("SecurityType", ListSortDirection.Ascending);

//GroupDescriptor descriptor2 = new GroupDescriptor();

//descriptor2.GroupNames.Add("InstrumentGroup", ListSortDirection.Ascending);

//mcboInstrumentComboElement.EditorControl.GroupDescriptors.Add(descriptor);

//mcboInstrumentComboElement.EditorControl.GroupDescriptors.Add(descriptor2);

//mcboInstrumentComboElement.EditorControl.GroupSummaryEvaluate += new GroupSummaryEvaluateEventHandler(EditorControl_GroupSummaryEvaluate);

}

Data is entered using this method and for testing there is only a single row as follows:
SecurityType="Forex", InstrumentGroup="EUR", Instrument="EUR/USD"

private void PopulateInstrumentList()

{

StrategyDistinctInstruments instruments = new StrategyDistinctInstruments(ThisVariation.StrategyVariation);

Dictionary<string, BacktestInstrument> uniqueInstruments = instruments.UniqueInstruments;

mcboInstrumentComboElement.EditorControl.TableElement.BeginUpdate();

foreach (KeyValuePair<string, BacktestInstrument> kvp in uniqueInstruments)

{

GridViewRowInfo rowInfo = mcboInstrumentComboElement.EditorControl.Rows.AddNew();

rowInfo.Tag = kvp.Value.Inst;

rowInfo.Cells[0].Value = kvp.Value.SecurityType;

rowInfo.Cells[1].Value = kvp.Value.InstrumentGroup;

rowInfo.Cells[2].Value = kvp.Value.Inst.Name;

}

mcboInstrumentComboElement.EditorControl.TableElement.EndUpdate(true);

}

Complete gridview with empty rows

Hi everybody,

I would like to know if it is possible to complete a gridview with empty rows?

For example, I have a grid view which can contain 9 rows but I only have 3 items to show.
The bottom of my grid is empty and I'd prefer having empty rows than nothing!

How can I do this?

Thanks

Page View is SUPER slow

I have a page view in my application. Programmatically, I add 3 pages. On each page I add a TableLayoutPanel. Inside each panel I add about 15 rows with 2 columns each. Each column has one label and one "other" control. The "other" control is one of the following...

RadTextBox
RadCheckBox
RadDropDownList
RadSpinEditor

The pages with the drop down and spin editor takes several seconds to load and my processor is pegged!

I'm not hitting the database at this time, it is definitely in the control.

custom item creation from an object list

Hi,

I have few questions about how to create custom item in RadListView.

I have a list of objects and would like to create custom item for each of the object. The value of visualElements of each custom item will get from properties value of associated object.

By reading the online documents, I know that the custom visual item is created by caling VisualItemCreating event. But how can I trigger the event?

As I understand the function SynchronizeProperties() is used to assign values to visualElements when the custom visual items are created (please let me know if I am wrong). In the example code, the value assigned to custom visual item are from data table. But In my case I want to assign the value of properties of a object from the object list to each custom visual item. What steps I need to go through to achieve that?

Thanks a lot

SelectedRows

Hi, everyone,

I have been using telerik controls for windows for few months now, and this may be a stupid question. I've noticed that when a radgrid has been filtered or sorted, the SelectedRows property shows only one row selected even though more than one has been selected. I had a piece of code that uses that property so that on the edition of one row the value is copied to the other rows.

Here's a sample of my code:

Private Sub rgvContractDetails_CellEndEdit(sender As Object, e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles rgvContractDetails.CellEndEdit

Try

If rgvContractDetails.SelectedRows.Count > 1 Then

Select Case e.Column.Name

Case "Quantity"

For Each Row As GridViewRowInfo In rgvContractDetails.SelectedRows

Dim oSelectedItem As SalesContractDetail = Row.DataBoundItem

Row.Cells("Quantity").Value = e.Value

oSelectedItem.QuantityStr = e.Value

oSelectedItem.CalculateBalance()

Row.Cells("QtyBalance").Value = oSelectedItem.BalanceStr

Next

Case "QtyCancel"

For Each Row As GridViewRowInfo In rgvContractDetails.SelectedRows

Dim oSelectedItem As SalesContractDetail = Row.DataBoundItem

Row.Cells("QtyCancel").Value = e.Value

oSelectedItem.CancelStr = e.Value

oSelectedItem.CalculateBalance()

Row.Cells("QtyBalance").Value = oSelectedItem.BalanceStr

Row.Cells("CancelDate").Value = Today.ToShortDateString

Next

End If

Catch ex As Exception

MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)

End Try

End Sub

Is this the default behavior? If so, is there a workaround so that I can persist the selected rows programmatically and keep my code as it is? I am using version 2011.02.712.

Thanks for your help,

Mauricio.
