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.
Code Snippet:
protected void gvHrEmploye_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == System.Web.UI.WebControls.DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#EEFFAA'");
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)
{
e.Row.Attributes.Add("onmouseover", "this.originalstyle=this.style.backgroundColor;this.style.backgroundColor='#EEFFAA'");
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=this.originalstyle;");
}
}
It works properly even if you set AlternatingRowStyle
property or the row is previously selected.
