Question

I have a sqldatasource and gridview.

I have two columns:

ID | Status
1   Closed
2   Opened
3   Waiting

How to change the color of the label in the view state of the gridview depeding on the value from the 'status' column.

For example if the value in the cell is “Closed” the label color will be red , if it’s opened then it will become green and so on.

I’ve thought about looping through all cells of the status column and if the cell contains a certain value the color will change. ( in row data bound event ) . But I haven’t done this because I don’t find this idea as a good one because of the looping part.

You can enable the RowDataBound Event in the markup

<asp:GridView ID="gridview1" runat="server" OnRowDataBound="RowDataBound">

</asp:GridView>

And put this in your Code-Behind file.

protected void RowDataBound(Object sender, GridViewRowEventArgs e)
   {
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
       // Retrieve the underlying data item. In this example
       // the underlying data item is a DataRowView object. 
       DataRowView rowView = (DataRowView)e.Row.DataItem;

       // Retrieve the state value for the current row. 
       String state = rowView["state"].ToString();

        //format color of the as below 
        if(state == "Closed")
                (e.Row.FindControl("lbl1") as Label).BackColor  = Color.Red;

        if(state == "Open")
                (e.Row.FindControl("lbl1") as Label).BackColor = Color.Green;

        if(state == "Waiting")
                (e.Row.FindControl("lbl1") as Label).BackColor = Color.Yellow;

   }
}
