Hi Members,

I have a grid view that is populated dynamically through a stored procedure

I would like to ask how can I set the colour of the value for column17 upon populating the gridview?
For example, for value range between 1 - 20 I would like to the colour to be green, value between 21-40 to be orange and 41 - 60 to be red?

My codes to populate the gridview:

C#

using (SqlCommand cmd = new SqlCommand(spretrieve, conn))
                    {
     cmd.CommandType = CommandType.StoredProcedure;
                            cmd.Parameters.Add("@param1", SqlDbType.VarChar).Value = DATE;
                            cmd.Parameters.Add("@param2", SqlDbType.VarChar).Value = Key;
    string query = cmd.CommandText;
    
    conn.Open();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    da.Fill(ds);
    Gridview1.DataSource = ds.Tables[0];
    Gridview1.DataBind();

I had done this in my GridView

XML

<asp:TemplateField HeaderText="Correct Filling No">
                                            <ItemTemplate>
                                                <asp:Label ID="Label10" runat="server" Text='<%# Bind("CorrectFillingNo") %>'></asp:Label>
                                            </ItemTemplate>
                                            <EditItemTemplate>
                                                <asp:DropDownList ID="ddlcorrectFillingNo" runat="server" SelectedValue='<%# Eval("CorrectFillingNo").ToString()=="" ? "Yes" : Eval("CorrectFillingNo") %>'
                                                    CssClass="textareadropdown" BackColor='<%# Eval("CorrectFillingNo").ToString()=="No" ? System.Drawing.Color.Red : System.Drawing.ColorTranslator.FromHtml("#F3F3F3")  %>'>
                                                    <asp:ListItem Selected="True">Yes</asp:ListItem>
                                                     <asp:ListItem>No</asp:ListItem>
                                                    <asp:ListItem>N/A</asp:ListItem>
                                                </asp:DropDownList>
                                            </EditItemTemplate>
                                        </asp:TemplateField>

Hi,

OnRowDataBound event you can make the color against cell using conditions, Refer below sample.

C#

protected void gv_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
     if(e.Row.RowType==DataControlRowType.DataRow)
     {
          int value=Convert.ToInt32(((Label)e.Row.FindControl("lblValue")).Text); // If you are using a TemplateField
          

          if(value > 1 && value < 20 )
          {
              e.Item.BackColor = System.Drawing.Color.Green;
          }
          else if(value > 21 && value < 40 )
          {
              e.Item.BackColor = System.Drawing.Color.Orange;
          }
          else if(value &gt; 41 &amp;&amp; value &lt; 60 )
          {
              e.Item.BackColor = System.Drawing.Color.Red;
          }

     }
}

Hello Permalink,

Its very easy with RowDatabound event of the Gridview Controll

Select The Grid View Control =>Properties=>events=>rowDatabound double click and past the code below :

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int iCellValue=Convert.ToInt32(e.Row.Cells[16].Text);
if (iCellValue >= 1 && iCellValue <= 20)
{
e.Row.Cells[16].BackColor = System.Drawing.Color.Green;

}
else if (iCellValue >= 21 && iCellValue <= 40)
{
e.Row.Cells[16].BackColor = System.Drawing.Color.Orange;

}
if (iCellValue >= 41 && iCellValue <= 60)
{
e.Row.Cells[16].BackColor = System.Drawing.Color.Red;

}
}
}
