Use onrowediting and onrowupdating in gridview markup...
some thing like
<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333"
GridLines="None" AllowPaging="true" AllowSorting="true" PageSize="5" DataKeyNames="Id"
onpageindexchanging="GridView1_PageIndexChanging"
AutoGenerateEditButton="true" AutoGenerateDeleteButton="true"
onsorting="GridView1_Sorting" onrowediting="GridView1_RowEditing">
EDIT:
Hey I am not very sure abt winforms, but in websites try this..
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
//your code that will edit/update.
}
in general code with Sqlcommand and connection will be something like"
SqlConnection con;
SqlCommand cmd;
DataSet ds;
SqlDataAdapter da;
protected DataSet FillDataSet()
{
string source = "Database=GridTest;Server=Localhost;Trusted_Connection=yes";
con = new SqlConnection(source);
cmd = new SqlCommand("proc_mygrid", con);
ds = new DataSet();
da = new SqlDataAdapter(cmd);
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
return ds;
}
Hope this helps.
