Hello Miriam,
I advise that you first examine the following two sections of the documentation on getting data from a grid and on accessing controls in a template column:
Here's an example that applies that to the provided snippet where I highlighted the key changes:
protected void dg_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
(sender as RadGrid).DataSource = GetDummyData();
}
protected DataTable GetDummyData()
{
DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("Idtip", typeof(decimal)));
tbl.Columns.Add(new DataColumn("Nombre", typeof(string)));
tbl.Columns.Add(new DataColumn("otherField", typeof(string)));
tbl.Columns.Add(new DataColumn("FourthField", typeof(string)));
tbl.Rows.Add(new object[] { 1, "one", 11, "red" });
tbl.Rows.Add(new object[] { 2, "two", 22, "green" });
tbl.Rows.Add(new object[] { 3, "three", 33, "blue" });
tbl.Rows.Add(new object[] { 4, "four", 44, "pink" });
return tbl;
}
protected void btnEditlist_Click(object sender, EventArgs e)
{
GridDataItem grdRow = (sender as Control).NamingContainer as GridDataItem;
string data = grdRow.GetDataKeyValue("Idtip").ToString();
Response.Write(data);
}
