protected void DrugGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
// To check condition on integer value
if (Convert.ToInt16(DataBinder.Eval(e.Row.DataItem, "Dosage")) == 50)
{
e.Row.BackColor = System.Drawing.Color.Cyan;
}
}
Create GridView1_RowDataBound
event for your GridView.
//Check if it is not header or footer row
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Check your condition here
If(Condition True)
{
e.Row.BackColor = Drawing.Color.Red // This will make row back color red
}
}
protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lbl_Code = (Label)e.Row.FindControl("lblCode");
if (lbl_Code.Text == "1")
{
e.Row.BackColor = System.Drawing.ColorTranslator.FromHtml("#f2d9d9");
}
}
}
\\loop throgh all rows of the grid view
if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value1")
{
GridView1.Rows[i - 1].ForeColor = Color.Black;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value2")
{
GridView1.Rows[i - 1].ForeColor = Color.Blue;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value3")
{
GridView1.Rows[i - 1].ForeColor = Color.Red;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value4")
{
GridView1.Rows[i - 1].ForeColor = Color.Green;
}
Alternatively, you can cast the row DataItem to a class and then add condition based on the class properties. Here is a sample that I used to convert the row to a class/model named TimetableModel, then in if statement you have access to all class fields/properties:
protected void GridView_TimeTable_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var tt = (TimetableModel)(e.Row.DataItem);
if (tt.Unpublsihed )
e.Row.BackColor = System.Drawing.Color.Red;
else
e.Row.BackColor = System.Drawing.Color.Green;
}
}
}
This method modifies both the back color (to dark red) and the text (to white) if a specific string ("TextToMatch") occurs in one of the columns:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.Cells[8].Text.Equals("TextToMatch"))
{
e.Row.BackColor = System.Drawing.Color.DarkRed;
e.Row.ForeColor = System.Drawing.Color.White;
}
}
Or another way to write it:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.Cells[8].Text.Equals("TextToMatch"))
{
e.Row.Attributes.CssStyle.Value = "background-color: DarkRed; color: White";
}
}
