Simple question that I was not quite able to find an answer to...
I have a binding list collection of Person objects. Each Person object has a collection of Person objects. For example, everyone is a person. Some persons have children. They are persons. They can have kids, and so on and so on.
I bound this to a tree view but only got the first level of items. I then added ParentMember and ChildMember values - these are used for a simple collection as compared to my hierarchy of same nodes thus it did not work. I then tried to use the Object Relation mode and specified a display value that hit the first level of nodes and then went to the second level - "PersonName\\PersonName". I did the same with the ValueMember. Great, I now got two levels of tree control.
The question is how to get N levels? Do I do something like "PersonName\\*" in an attempt to tell it to repeat? Do I need to do this manually rather than binding?
And lastly, I did read that Drag And Drop will NOT work with bound Trees. If that is the case then I will do all of this work manually - I would think that you could support drag and drop but would have to rely on my code to actually do the movement of the actual data structure.

I have a RadGridView with a GridViewDecimalColumn. A row has the value of 51.34. I set the DecimalPlaces property to 0 but the value still displays as 51.34. Should this not display as 51?

I have set my RadDock MainDocumentContainerVisible = false and BorderStyle = none. But there is still a borderline on the left and top. If I set the BorderStyle to FixedSingle, the whole thing has a border, but the Left and Top still have an extra wide border. What is causing this?
Thanks,

I have radgridview with data written in design time i.e, code
this.radGridView1.Rows.Add("Jjkh", 19, 2, 9, 12, 21,52, 44, 63,56, System.DateTime.Now);
this.radGridView1.Rows.Add("Jjkh", 10, 2, 9, 12, 21, 52, 44, 63, 87, System.DateTime.Now);
this.radGridView1.Rows.Add("eur", 16, 2, 9, 12, 21, 52, 44, 63, 34, System.DateTime.Now);
this.radGridView1.Rows.Add("usd", 14, 2, 9, 12, 21, 52, 44, 63, 23, System.DateTime.Now);
this.radGridView1.Rows.Add("Jjkh", 67, 81, 33, 4, 55, 66, 7, 7, 11, System.DateTime.Now);
After this i've written code for forecolor:
for (int i = 0; i < radGridView1.Rows.Count; i++)
{
for (int j = 1; j < 4; j++)
this.radGridView1.Rows[i].Cells[j].Style.ForeColor = System.Drawing.Color.White;
this.radGridView1.Rows[i].Cells[4].Style.ForeColor = System.Drawing.Color.Blue;
this.radGridView1.Rows[i].Cells[5].Style.ForeColor = System.Drawing.Color.Red;
}
But for back color, i've written in radGridView1_CellFormatting,
e.CellElement.BackColor = Color.Blue;
But the event radGridView1_CellFormatting is not binding with any method..
this.radGridView1.Rows.Add("Jjkh", 19, 2, 9, 12, 21,52, 44, 63,56, System.DateTime.Now);
this.radGridView1.Rows.Add("Jjkh", 10, 2, 9, 12, 21, 52, 44, 63, 87, System.DateTime.Now);
this.radGridView1.Rows.Add("eur", 16, 2, 9, 12, 21, 52, 44, 63, 34, System.DateTime.Now);
this.radGridView1.Rows.Add("usd", 14, 2, 9, 12, 21, 52, 44, 63, 23, System.DateTime.Now);

Prior to using RadGridView, i made use of the new DataGridView in .NET 2.0.
consider the code below, where i successfully populate the row headers:
string[] userInputParams = new string[] {"apples","oranges",
"mangos",
"guanábana"}
for (int i = 0; i < userInputParams.Length; i++)
{
gridRows.Add();
gridRows[i].HeaderCell.Value = userInputParams[i];
}
How would i acheive this with the telerik RadGridView winform control?
thank you

Hi,
I've noticed that you can check whether the selected font in the richtextbox is bold or italic, but not whether it is both bold and italic. Checking for bold or italic can be done likeso:
However, I cannot seem to find a way to check for both bold and italic text, as the only members of TextStyle are Bold, Italic, and Regular. Is there a way to do this?

Hi, I'm starting developing with Telerik WinForms and WebForms controls. First of all, I'm changin' a System TreeView for a Telerik TreeView. I wasn't hard, but, in my last Tree, I had one property for sort a custom level of the tree. I'd make a class NodeComparer that implements IComparer. Now, in Telerik, I read that this property is called RadTreeNodeComparer, and needs a class that implements IComparer<RadTreeNode>.
So, the code is like this:
UIPresentationTree.RadTreeNodeComparer = new NodeSorter();
Nothing happens, and the tree don't sort anything. What's wrong?
thanks.
