You can achieve this in windows form by: Attach to the event this . dataGridView1 . RowPrePaint += new System . Windows . Forms . DataGridViewRowPrePaintEventHandler ( this . dataGridView1_RowPrePaint ); The event code private void dataGridView1_RowPrePaint ( object sender  DataGridViewRowPrePaintEventArgs e ) { // your condition here if ( Convert . ToInt32 ( dataGridView1 . Rows [ e . RowIndex ]. Cells [ 7 ]. Text ) Convert . ToInt32 ( dataGridView1 . Rows [ e . RowIndex ].. Cells [ 10 ]. Text )) { dataGridView1 . Rows [ e . RowIndex ]. DefaultCellStyle . BackColor = Color . Beige ; } } Do let me know if it solves your problem

Add following code in *.aspx page: asp:GridView ID = TaskNameGrid runat = server AllowPaging = True AutoGenerateColumns = False CssClass = SearchResultsTable virtualitemcount1 = -1 Width = 400px DataSourceID = ObjectDataSource1 onrowdatabound =  Update_RowDataBound  > AlternatingRowStyle CssClass = alternate /> Columns > asp:BoundField DataField = BusinessIdentifier HeaderText = BusinessIdentifier SortExpression = BusinessIdentifier /> asp:BoundField DataField = SLA HeaderText = SLA SortExpression = SLA /> Columns > HeaderStyle ForeColor = White /> RowStyle /> asp:GridView > Next add following code in Code-behind(*.aspx.cs) file: protected void Update_RowDataBound( object sender GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { // Getting value from gridview row cell int quantity = int .Parse(e.Row.Cells[1].Text); // Logic to change color dynamically if (quantity > 100) { e.Row.BackColor = System.Drawing.Color.Red; } else { e.Row.BackColor = System.Drawing.Color.Green; } } }
