Listen to GridButtonColumn click in javascript

[Kirie]

Hi, i have a grid with a GridButtonColumn. When the button is clicked i want to redirect the user (in javascript, and pass a long the bound value of the GridButtonColumn). i found how to do this serverside, but i cant figure out how to catch the click (and the value) in javascript.

Any help would be appriciated.

Hello Kirie,

Try the following code.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
{
  GridDataItem item = (GridDataItem)e.Item;
  LinkButton link = (LinkButton)item["ColumnUniqueName"].Controls[0];
  link.Attributes.Add("onclick", "functionName('" + item.ItemIndex + "');");
 }
}

Thanks,
Princy.

Thank you for your swift answer Princy,

but what if i want to send the bound DataTextField as a parameter to the javascript method, (or one of the other columns bound value), how can I acheieve that? I am kind of new to javascript :)

Best regards
Kirie

Hello Kirie,

Try the following javascript:
JS:

function functionName(index)
{
   var row = $find('<%= RadGrid1.ClientID %>').get_masterTableView().get_dataItems()[index];
   alert(row.getDataKeyValue("ID"));
}
