Gridview control is a customizable and flexible control used to display
data in tabular format. It has some nice features. But lacks of some
client side features that makes web users happy. We can easily add
these features with few lines of code.
For example, a common task is to highlight gridview row on mouse over
which is not provided with gridview control. Here we will see how
easily we can do the task.
In order to change gridview row color we need to add/remove style attributes to that specific row using JavaScript onmouseover and onmouseout client event. We can do it on RowDataBound or RowCreated gridview event.
protected void gvHrEmploye_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == System.Web.UI.WebControls.DataControlRowType.DataRow)
{
// when mouse is over the row, save original color to new attribute, and change it to highlight color
e.Row.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#EEFFAA'");
// when mouse leaves the row, change the bg color to its original value
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=this.originalstyle;");
}
}
or,
protected void gvHrEmploye_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == System.Web.UI.WebControls.DataControlRowType.DataRow)
{
// when mouse is over the row, save original color to new attribute, and change it to highlight color
e.Row.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#EEFFAA'");
// when mouse leaves the row, change the bg color to its original value
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=this.originalstyle;");
}
}
