You can use AlternateRowStyle property of DataGridView or DataGrid to do this...

Naman GoelCommented:
use following property of DefaultCellStyle.BackColor property of DataGridViewRow

like following

dataGridView.CurrentRow.DefaultCellStyle.BackColor = System.Drawing.Color.Aqua;

also refer to following links for more info :

Additional Info for the above query: Using AlternateRowStyle will enable you to use only 2 different colors for rows. If your intentions/requirements is to be able to color every row with a new color, you will have to create a logic and apply that in the Row_Created event of the DataGridView

Hi you can use the ItemDataBound property for the DataGrid to set the differnt colours  as per the condition

public virtual void GridView2_ItemDataBound(object sender, DataGridItemEventArgs e)
        {
            System.Web.UI.WebControls.ListItemType itemType = (System.Web.UI.WebControls.ListItemType)e.Item.ItemType;
            class dt = (e.Item.DataItem) as class;

            if (e.Item.ItemType == ListItemType.Header)
            {
                e.Item.BackColor = System.Drawing.Color.Black;
                e.Item.ForeColor = System.Drawing.Color.White;
            }
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                e.Item.ForeColor = System.Drawing.Color.SaddleBrown;
                if (dt.estimation.ToString() == "8")
                {
                    e.Item.BackColor = System.Drawing.Color.RosyBrown;
                    
                }
                else if (dt.estimation.ToString() == "10")
                {
                    e.Item.BackColor = System.Drawing.Color.Tomato;
                }
                else
                {
                    e.Item.BackColor = System.Drawing.Color.RoyalBlue;
                }
            }

I don't see _ItemDataBound  as a member of the DataGrid, unfortunately I can't use any of the code.

sameer_goyalCommented:
ItemDataBound is an event for DataGrid and not for DataGridView. For DataGridView, you have to use RowCreated event. I believe, the MSDN link I provided above should have helped you.

amielDorelAuthor Commented:

Unfortunately, there is no RowCreated event for the DataGridView,  (windows form application)

sameer_goyalCommented:
Ok so it was Windows App you are working with. Try 'RowsAdded' event then,

Please provide an example to work in a windows App. (similar to the one provided before)

hey,

sorry for the misleading .. i have named my datagrid as as GridView1

here is the following aspx code..
 <asp:DataGrid ID="dgView" runat="server" OnItemDataBound="GridView2_ItemDataBound" >
        </asp:DataGrid>

Open in new window

paste this code in your aspx.cs page
public virtual void GridView2_ItemDataBound(object sender, DataGridItemEventArgs e)
        {
            System.Web.UI.WebControls.ListItemType itemType = (System.Web.UI.WebControls.ListItemType)e.Item.ItemType;
            yourownclass dt = (e.Item.DataItem) as yourownclass;

            if (e.Item.ItemType == ListItemType.Header)
            {
                e.Item.BackColor = System.Drawing.Color.Black;
                e.Item.ForeColor = System.Drawing.Color.White;
            }
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                e.Item.ForeColor = System.Drawing.Color.SaddleBrown;
                   // assume that you have the estimation column in your datasource which will have
                   // different values like 8,10,5 based on estimation i am setting the back colour as differnt 
                   //one
                if (dt.estimation.ToString() == "8") 
                {
                    e.Item.BackColor = System.Drawing.Color.RosyBrown;
                    
                }
                else if (dt.estimation.ToString() == "10")
                {
                    e.Item.BackColor = System.Drawing.Color.Tomato;
                }
                else
                {
                    e.Item.BackColor = System.Drawing.Color.RoyalBlue;
                }
            }

Here is the solution

Here I am using dataGridView1_CellFormatting event for this

My grid contains and ID Column which contains serial number as its values

I am trying to represent even number row with black background color and odd number with smoke white.

You can use this logic to change background color at your own choice.




private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (e.RowIndex >= 0 && e.ColumnIndex == dataGridView1.Columns["ID"].Index)
            {
                if (e.Value!=null && e.Value.GetType()== typeof(int))
                {
                    int value = int.Parse(e.Value.ToString());
                    if (value % 2 == 0)
                    {
                        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.ForeColor = Color.White;
                        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Black;
                    }
                    else
                    {
                        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.ForeColor = Color.DarkGreen;
                        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.WhiteSmoke;
                    }
                }
            }
        }
