Introduction:
In this article,i am going to explain about how to format or design a gridview rows using available gridview properties.

Main:
we can format the GridView rows as per your requirements.For ex,if you wants to set a property for alternating row,

AlternatingRowStyle-BackColor =”Blue”

If you wants to format a gridview row at runtime the OnRowCreated is the best option,

protected void OnRowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if (((e.Row.RowIndex + 1)) == 5) { e.Row.BackColor = System.Drawing.Color.Red; } } }

if you wants to set some style in onmouseover and onmouseout then,

protected void OnRowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='Blue'"); e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='skyBlue'"); } }

if you wants to display the gridview row data into alert then,

protected void OnRowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { int rowIndex = e.Row.DataItemIndex; rowIndex += 1; e.Row.Attributes.Add("onClick", "alert('I am gridview row and my data is : " + rowIndex.ToString()+ "')"); } }

Sometimes we need to foramt the display some of the fields,for ex date,

DataFormatString=”{0:d}”

For Currency,
DataFormatString=”{0:C}”

Conclusion:
Hope this helps,
Happy Coding.
