FIlter Gridview column on another column

Hi

I would like to be able to filter my gridview based on the the value of two columns.

So as an example I have a grid view containing two Amount columns and I'd like to implement filtering so that they could filter the results based on any one of the following criteria:

Amount 1 > Amount 2
Amount 2 > Amount 1
Amount 1 = Amount 2

Is this possible to do? I am using 2009 Q2 and am unable to upgrade to the latest version.

Thanks

Adding Other Controls to the RibbonBar

Good Afternoon,

I am trying to add some controls to a chunk of the ribbon bar. the control in particular i am trying to add is the radcombobox. According to your instructions in the help documentation

<quote>To insert one of these elements into the telerik r.a.d.ribbonbar, right-click inside of a chunk or a button group and select Add an Item or Insert Sibling followed by the name of the element. You can then proceed to set the properties of the element using the Property window as you normally would. Refer to the linked topics for further information on the individual elements.</quote>

However, when i follow these instructions the only available items are:

RadRibbonBarButtonGroup
RadButtonElement
ActionButtonElement
RadRepeatButtonElement
RadToggleButtonElement
RadCheckBoxElement
RadImageButtonElement
RadGalleryElement

Am i missing something obvious? if now how can i get the combobox to appear in design time?

Thanks,

Chris.

Applying a theme to a RadMultiColumnComboBoxElement

Hi,

I am applying a theme to the dropDownElement of a RadMulticolumnComboBox column. But it is not applyed until the second time the dropDownElement is displayed. How can I do it to apply it all the times, including the first time.

I have tried to do this in two events. Here is the code if I use CellEditorInitialized:

Private Sub Grid_CellEditorInitialized(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles Grid.CellEditorInitialized

If e.Row.Cells(e.ColumnIndex).ColumnInfo.Name = "multiComboGrupo" Then

Dim editor As RadMultiColumnComboBoxElement = CType(Grid.ActiveEditor, RadMultiColumnComboBoxElement)

editor.EditorControl.ThemeName = "UYA_Multicolu"

End if

End Sub

I even tryed with CellBeginEdit event:

Private Sub Grid_CellBeginEdit(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles Grid.CellBeginEdit

If Grid.CurrentRow.Cells(e.ColumnIndex).ColumnInfo.Name = "multiComboGrupo" Then

Dim editor As RadMultiColumnComboBoxElement = CType(Grid.ActiveEditor, RadMultiColumnComboBoxElement)

editor.EditorControl.ThemeName = "UYA_Multicolu"

End if

End Sub

Thank you.

RadToolstrip behaviour when form resized and part of strip hidden

Hi
I have a RadToolstrip with various RadToolStripItems on it and looking foe options to handle it when the user resizes the mdi form.

I have seen from a previous post that the toolstrip can't automatically wrap the parts of the strip that would be hidden by the form resize onto another row but is there something to do with the OverflowButton property that I can use to at least let the user see the hidden toolbar items? I can't find the property that needs to be set to allow this.

Many Thanks
Steve

GridViewMultiComboBoxColumn

Hello ,

Lets see If column "CategoryName" is the first column ,
So , first I'm writing :

radGridView1.DataSource = dtDataTable;

after this line goes code:

radGridView1.Columns.Remove("CategoryName");

GridViewMultiComboBoxColumn column = new GridViewMultiComboBoxColumn();

column.FieldName = "CategoryName";

radGridView1.Columns.Add(column);

the new column appears at the end , so I have to move it at the right place:

radGridView1.Columns.Move(radGridView1.Columns.Count - 1, 0);

But what happened with retrieved values of this column?
The column is empty.
So do I have to loop through and copy all the values from the removed column and assign them to the new one or there is a solution that all originally retrieved values are reflected in a new MultiComboBoxColumn?

In a case when I'm trying to assign the values .. it does not work because the cells after this assignment still empty...???? :

if (dtSource.Rows.Count > 0)

{

for (int i = 0; i < radGridView1.Rows.Count; i++)

{

radGridView1.Rows[i].Cells["c_price_lob"].BeginEdit();

radGridView1.Rows[i].Cells["c_price_lob"].Value = dtSource.Rows[i][3].ToString();

radGridView1.Rows[i].Cells["c_price_lob"].EndEdit();

}

Thank you ,
Victoria.

host UserControl in Carousel

Hi.
I'm trying to create a TabControl with a movment-change affect between tabs.
To do this, I need to do 2 things:

1. Can I put UserControl as the Carousel element?
2. Can I control the movment path of the carousel? (I just want a horizontal movment, and not circular)

Thanks.

Default Date in DateTimePicker

Hi -

I have a RadDateTimePicker column in my grid that is initially null. So I am calling SetToNullValue.

But when the user opens the RadDateTimePicker, we would like to set a default date. It appears to use the MinDate for the default date, which my user's don't like.

For example, for a search feature the system defaults to no date criteria (a null value date). But the user can search up to 3 months back (.MinDate = Today.AddMonths(-3)) But the user's don't want to default to this date when the calendar opens.

So is there an easy way to set a default date in this case?

Thanks!
