Hi ,

I need to use a two dimensional grid seems like that : 


source\destination          192.168.1.1             192.168.1.5

192.168.1.1     N/A                             4.8


192.168.1.5                         4.3                              N/A

Is it possible to configure Rad Grid View for that or I need to use an other control ?

Best regards.

Aurélien

Hi Aurélien Dubosson,

RadGridView displays data. It is now aware of the semantic meaning of the data it is displaying.

If you prepare your data to be in the format that you have described -- RadGridView will show it just like this.

For example:

public class Row
{
public string SourceDestination{get; set;}
public string IP1 {get; set;}
public string IP2 {get; set;}
}

List<Row> data = new List<Row>();
data.Add(new Row(){SourceDestination="192.168.1.1", IP1="N/A", IP2="4.8"});
data.Add(new Row(){SourceDestination="192.168.1.5", IP1="4.3", IP2="N/A"});

grid.ItemsSource = data;

Then you can use the Header property of each column if you want to change the header text that is displayed.

In other words you can easily transform your original data into a suitable .NET list and the simply feed to the grid. It will display it in the way that you have prepared it.

I hope this helps. Let us know if you have any other questions.

Best wishes,

This approach will work when we have fixed number of elements in columns dimension, but what to do when we should dynamically configure the number of columns?

Hello Aurélien Dubosson,

You can use my colleague Vladimir Enchev's Lightweight DataTable for Silverlight.

You can create and configure the data table at run-time. Add any columns that you want. Give them any names that you want. Then fill the DataTable with the correct data. Finally, bind RadGridView to this DataTable.

I hope this helps.

Sincerely yours,
Ross

It's more the design of the headers I'm looking for . Like if the headers were in the first line and first column, same background .

Hello Telerik,

I tried to use the class DataTable suggested by you with the following code : 

   DataTable table = new DataTable();
            table.Columns.Add(new DataColumn() { ColumnName = "Src/Dest", DataType = typeof(string) });
            table.Columns.Add(new DataColumn() { ColumnName = "192.168.1.1", DataType = typeof(string) });
            table.Columns.Add(new DataColumn() { ColumnName = "192.168.1.5", DataType = typeof(string) });

            DataRow row1 = new DataRow();
            DataRow row2 = new DataRow();

            row1["Src/Dest"] = "192.168.1.1";
            row1["192.168.1.1"] = "N/A";
            row1["192.168.1.5"] = "5,1";

            row2["Src/Dest"] = "192.168.1.5";
            row2["192.168.1.1"] = "4,8";
            row2["192.168.1.5"] = "N/A";

            table.Rows.Add(row1);
            table.Rows.Add(row2);

            Grid.ItemsSource = table;

The Grid is a GridView but when I execute this code I don't see my two rows created before 

What's the problem ?
