Showing an image for a new row

[Derek]

Hi,
I would like to show an image on a row, but only if it's a new row, is this possible?

Thanks.

Hello Derek,

You can do this by using the Tag property of GridViewRowInfo. Just set it to some value when processing the DefaultValuesNeeded method and check it when processing the CellFormatting event. Take a look at the sample below:

this.radGridView1.Columns.Add(new GridViewImageColumn("Image"));

this.radGridView1.DefaultValuesNeeded += new GridViewRowEventHandler(radGridView1_DefaultValuesNeeded);
this.radGridView1.CellFormatting += new CellFormattingEventHandler(radGridView1_CellFormatting);

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement.ColumnInfo.HeaderText == "Image" && e.CellElement.RowInfo.Tag != null)
    {
        e.CellElement.Image = Resources.blue;
    }
}

void radGridView1_DefaultValuesNeeded(object sender, GridViewRowEventArgs e)
{
    e.Row.Tag = "new";
}

I hope this helps. Do not hesitate to contact me if you need further assistance.

All the best,
