You can highlight a Row in **GridView** by using the `onmouseover` event. The following code will color the **GridView** row while mouse hovering.
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "this.style.backgroundColor='aquamarine';";
e.Row.Attributes["onmouseout"] = "this.style.backgroundColor='white';";
}
The resulting code is below: You can also get the selected Gridview cell value using `OnSelectedIndexChanged` event:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "this.style.backgroundColor='aquamarine';";
e.Row.Attributes["onmouseout"] = "this.style.backgroundColor='white';";
e.Row.ToolTip = "Click last column for selecting this row.";
}
}
protected void OnSelectedIndexChanged(object sender, EventArgs e)
{
string pName = GridView1.SelectedRow.Cells[1].Text;
msg.Text = "<b>Publisher Name : " + pName + "</b>";
}
Instead of doing it on RowCreated, you could do it on Render(). That way you could use the overload of GetPostBackClientHyperlink with true on registerForEventValidation and avoid the "invalid postback/callback argument" error.
Something like this:
protected override void Render(HtmlTextWriter writer)
{
foreach (GridViewRow r in GridView1.Rows)
{
if (r.RowType == DataControlRowType.DataRow)
{
r.Attributes["onmouseover"] = "this.style.cursor='pointer';this.style.textDecoration='underline';";
r.Attributes["onmouseout"] = "this.style.textDecoration='none';";
r.ToolTip = "Click to select row";
r.Attributes["onclick"] = this.Page.ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + r.RowIndex,true);
}
}
base.Render(writer);
}
