Is it possible to create a third column in a PropertyGrid? For example: PropertyName - PropertyValue - Units of Measure (ie: "Starting Length" - "1000" - "meters" or "Base Pressure" - "22" - "psi")
I'm guessing that I might need to create a custom PropertyGrid control that descends from RadPropertyGrid with the third column, and then maybe a custom PropertyStoreItem that includes a field for the third column value (in this case the units of measure). And then somehow bind it all together.
I am new to Telerik, and do not have any experience with your Telerik Presentation Framework.
Thank you.

I have a Access database (accdb file), one of its columns contains files with the image in attachment field. When i use this database as Data Source for RadGridView i see only the name of the attached file ("1.jpg", "2.jpg" etc), not the images. How can I see my images on RadGridView without editing database.

How to not Export specified columns for each parent row child rows when exporting to excel in telerik radgridview ui winf
I a have hierarchical telerik radgridview in winform. in this radgridview master template i have a rows that each row has child rows that are null in some columns for all child rows of that parent row and not for others.
I wrote a code that only let one parent row to be expanded and when expanding that parent row show only the columns that has value at least in one child row and hide columns that its child rows are all null for that parent row with radGridView1_ChildViewExpanded event handler.
My problem is when i want to export this hierarchical telerik radgridview to excel file. what should i do in exporting to achieve to what i described, means exports only the columns that have at least one value in its child rows and not export others for each parent row.
tnx

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?

Hi,
Is there any way we can have multiple columns based filtering in MultiColumnCombo...
Example:
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

Can anyone advise if it is possible to nest items in a rad drop down list in Winforms?
I've looked at the documentation which doesn't mention this, but would like to know if it is actually possible. Here's an example of what I need to do:
Yorkshire
Leeds
Bradford
Wakefield
Hampshire
Southhampton
Portsmouth
In the above list, I need to be able to select a value at all levels... eg Yorkshie or Leeds
Thanks in advance...

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.}

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?
