Question:
In my grid I have data in two columns same for couple of rows. Then again couple of other rows will same with different data.I want make them into alternative sections with colors
In below example(image).
Rows no 1 to 4 has 'High', 'High'. I want make them gray bgcolor for those rows. Rows no 5 to 8 has 'High','Low'. I want make them white bgcolor for those rows Rows no 9 to 12 has 'High','Medium'. I want make them again gray bg color for those rows. 
How can we do that?

OK -- just modify Leniel Macaferi's answer: (I'm mixing a little w/ vb because I'm not a c# guy -- sorry -- the point should still be clear though I hope)
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if(e.Row.RowType == DataControlRowType.DataRow) { // Display the company name in italics. Session("New_Pair_1") = e.Row.Cells[1].Text Session("New_Pair_2") = e.Row.Cells[2].Text If Session("New_Pair_1") <> Session("OLD_Pair_1") OR _ Session("New_Pair_2") <> Session("OLD_Pair_2") Then //no pair match with last record's pair //step 1, change the backcolor If e.Row.BackColor = Color.FromName("Gray") Then e.Row.BackColor = Color.FromName("White") Else e.RowlBackColor = Color.FromName("Gray") End If //Step 2, reset the "OLD" session vars Session("OLD_Pair_1") = Session("New_Pair_1") Session("OLD_Pair_2") = Session("New_Pair_2") End If } }

The most direct way is to bind the background value in your gridview's template to a method in the code behind that takes the two fields you care about as parameters and switches on these values returning the appropriate color string.
This is not the most elegant method I would think there is likely some natural grouping mechanisms built into gridview I may be unawares of, but this is simple to implement and use for a single case. Look at something more natural if you're a stickler or are going to implement this in many places.

Here is a VB example. It creates a comparable schema to what you have and then does the work during the "RowDataBound" event.
Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender Dim dt As New Data.DataTable dt.Columns.Add("Row No", GetType(Int32)) dt.Columns.Add("Age", GetType(String)) dt.Columns.Add("Annual Sales", GetType(String)) dt.Columns.Add("Assortment", GetType(String)) dt.Rows.Add(1, "High", "High", "CORE") dt.Rows.Add(5, "High", "Low", "CORE") dt.Rows.Add(9, "High", "Medium", "CORE") GridView1.DataSource = dt GridView1.DataBind() End Sub Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType <> DataControlRowType.DataRow Then Exit Sub End If Dim dr = DirectCast(e.Row.DataItem, Data.DataRowView).Row Select Case DirectCast(dr("Annual Sales"), String) Case "High" e.Row.BackColor = Drawing.Color.Gray Case "Low" e.Row.BackColor = Drawing.Color.White Case "Medium" e.Row.BackColor = Drawing.Color.Gray End Select End Sub

You could check the values of both columns for each row and do what is described here:
Change background color of GridView's Rows
Event to be handled:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if(e.Row.RowType == DataControlRowType.DataRow) { // Display the company name in italics. if(e.Row.Cells[1].Text.Equals("High") && e.Row.Cells[2].Text.Equals("High")) { e.Row.BackColor = Color.FromName("Gray"); } else if(e.Row.Cells[1].Text.Equals("High") && e.Row.Cells[2].Text.Equals("Low")) { e.Row.BackColor = Color.FromName("White"); } else if(e.Row.Cells[1].Text.Equals("High") && e.Row.Cells[2].Text.Equals("Medium")) { e.Row.BackColor = Color.FromName("Gray"); } } } Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
