Question

I am working in asp.net .net framework 4, i have a data grid and it has a column having values 1,2,3 etc, i want to rename them during binding with if condition, for example if value is 1 display YES, if value is 2, display NO, like that…
I know that grid has an event data bound, but i dont know how to change the value of cell on the bases of if condition in this event, please help.

Thanks

1. Use condition inline in .aspx:

   <%# ((int)Eval("Property")) == 0 ? "No" : "Yes" %>
   

2. Use method at codebehind to format value:

   .aspx

   <%# FormatMyValue(Container.DataItem) %>
   

   .cs

   public string FormatMyValue(object value)
   {
       return ((MyDataType)value).Property == 0 ? "No" : "Yes";
   }
   

3. Using RowDataBound event in codebehind (not elegant, but should work):

   protected void Page_Load(object sender, EventArgs e)
   {
       this.GridView1.RowDataBound += new GridViewRowEventHandler(GridView1_RowDataBound);
   }
   
   void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           // get date item
           MyDataType item = (MyDataType)e.Row.DataItem;
   
           // Set value in the necessary cell. You need to specify correct cell index.
           e.Row.Cells[1].Text = item.Property == 0 ? "No" : "Yes"; ;
   
       }
   }
