radDropDownList flashes previous list

I have two radDropDownLists. The contents of the second list change based on the item selected in the first list. When an item is selected in the first list, select the down arrow for the second list, and you see list2 for the item selected in list1. Select another item in list1, and the program changes the items in list2. When you select the down arrow for list2, you see the previous list items flash before the list is updated with list items that correspond to the selection in list1. You can see this demonstrated in Telerik's Demo Application - UI for WinForms. Select DropDown & List and then select First Look. In this example, you select an artist in list1 and the artist's albums are listed in list2. Select artist1 and see artist1's albums in list2. Select artist2 and briefly see artist1's albums flash in list2 and then see artist2's albums. Is there a way to get the list to update before it is displayed so there is not flashing of the previous list?

MultiColumnCombo Filtering

Hi,

Is there any way we can have multiple columns based filtering in MultiColumnCombo...

Example:

RadMultiColumnComboBoxElement

multiColumnComboElement = this.mcboSample.MultiColumnComboBoxElement;

multiColumnComboElement.EditorControl.MasterGridViewTemplate.AutoGenerateColumns =

false;

multiColumnComboElement.Columns.Add(

new GridViewTextBoxColumn("Code"));

multiColumnComboElement.Columns.Add(

new GridViewTextBoxColumn("RealName"));

multiColumnComboElement.Columns.Add(

new GridViewTextBoxColumn("NickName"));

multiColumnComboElement.Rows.Add(

"1011", "Paul Wight, Jr.", "Big Show");

multiColumnComboElement.Rows.Add(

"1022", "Carlos Colón, Jr.", "Carlito");

multiColumnComboElement.Rows.Add(

"2031", "Matthew Korklan", "Evan Bourne");

multiColumnComboElement.Rows.Add(

"2032", "Mike Mizanin", "The Miz");

multiColumnComboElement.Rows.Add(

"4101", "Paul Levesque", "Triple H");

this.mcboSample.AutoFilter = true;

this.mcboSample.DisplayMember = "NickName";

FilterExpression filter = new FilterExpression(this.mcboSample.DisplayMember, FilterExpression.BinaryOperation.AND,

GridKnownFunction.Contains, GridFilterCellElement.ParameterName);

filter.Parameters.Add(

GridFilterCellElement.ParameterName, true);

this.mcboSample.EditorControl.MasterGridViewTemplate.FilterExpressions.Add(filter);

The above works fine based on NickName but I would have like have one more filter option based on RealName as well.

Thanks

Yorkshire
Leeds
Bradford
Wakefield

In the above list, I need to be able to select a value at all levels... eg Yorkshie or Leeds

Thanks in advance...

Reset ContextMenu options after ContextMenuOpening

Hello,

I have a RadTreeView with a context menu showing different options depending on the node level. However, I need to reset the context menu after ContextMenuOpening because once a menu item is removed from the context menu it doesn't display again.

01.void radTreeEmployers_ContextMenuOpening(object sender, Telerik.WinControls.UI.TreeViewContextMenuOpeningEventArgs e){

02. if (e.Node.Level == 1 || e.Node.Level == 2)

03. {

04. for (int i = 0; i <= e.Menu.Items.Count - 1; i++)

05. {

06. if (e.Menu.Items[i].Name == "addEmployer")

07. e.Menu.Items.Remove(e.Menu.Items[i]);

08. }

09. }

10.}

Hide/Remove LoadLayout Column

I am calling LoadLayout on a RadGridView then using a factory class todynamically gets the properties of an object passed in and determines what properties should be shown. Based on what properties should be shown, the factory adds columns if they don't exist from the LoadLayout or gets the column if it does exist and configures it. But if a column was created from the LoadLayout and there is no property associated with it anymore, I need to hide or remove the column.

Based on other forum posts, I've tried:





gridView.MasterTemplate.Columns.Remove(name);
gridView.Columns.Remove(name);
 
if (gridView.MasterTemplate.Columns.Contains(name)) // returns false
{
    var col = gridView.MasterTemplate.Columns[name];
    col.VisibleInColumnChooser = false;
    col.IsVisible = false;
}
 
if (gridView.Columns.Contains(name)) // returns false
{
    var col = gridView.Columns[name];
    col.VisibleInColumnChooser = false;
    col.IsVisible = false;
}

If I break after the code above runs, I can see that the column is not longer in the the gridView's column collection, but when its rendered the column is displayed. How do I hide or remove a column immediately after calling LoadLayout?

Manually insert rows

Hi,

I am using code based on the project found here: http://www.telerik.com/forums/charts-inside-gridview-cells-problems-during-the-scrolling. It works for the most part, but SetContentCore gets called repeatedly and for whatever reasons. I'd like to manually add rows to the grid and disable the autogeneration of new rows on scrolling. For some reason this behaviour causes bugs on my end like duplicating rows multiple times, although the bindinglist passed to it as datasource doesn't contain duplicates. Note the sample project provided in the reference works just fine, so I couldn't reproduce the error.
