c# - How to load formated data in gridview?

Question

For example, I have a source(Id, Name) with some records. I want to bind it to GridView. But, I want to format each record before add it to GridView, for example, I want to write prefix "test" to all the record where field is "Name". I heared that I need to use onRowDataBound event, but I cant understand how.

Answer 1

First if you want to make little format on the data you are displaying, you can do this easily in your .aspx using Eval function to search on Google use this asp.net eval format

Second for your example check this question : Add prefix of http:// or https:// with Eval value

Answer 2

Use the DataFormatString in your gridview column. Ex:

<asp:BoundField DataField="name" DataFormatString="test_{0}" HeaderText="name" 
                    HtmlEncode="False" SortExpression="name" />

This will result in:

test_YourData

Answer 3

Well you can do that by capturing the binding event.

YourGrid.DataBound += YourGrid_RowDataBound

void YourGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
      e.Row.Cells[1].Text = "test_" + e.Row.Cells[1].Text;
  }
}
