How to combine columns using Telerik RadGrid control

Question

I know that I need to use template columns, but I don’t understand how to use it.

I have a data source that returns a collection, I can assign each property in the collection to a column.

But like me:

• Merge two columns? for example col.prop1 +' '+ col.prop2?
• Follow some methods for properties such as col.prop1.ToString(overloaded)

A simple codebehind example will help. All I can find are very complex controls and stuff for examples.

Thank.

You can also use calculated columns.

<telerik:GridCalculatedColumn HeaderText="Test" UniqueName="Test" DataType="System.String"
     DataFields="Field1, Field2" Expression='{0} + " - " + {1}'></telerik:GridCalculatedColumn>

public string Prop2 { get; set; }

public string PropertiesFormatted

  get
  {
    return this.Prop1 + " - " + this.Prop2;
  }
}
