hi, i am using BoundFields in gridview to bind the data to gridview...In row updating event i am getting old values only.i am not getting newly entered values ...why it is happening like that...

XML

<Columns>
    <asp:BoundField DataField="latitude" HeaderText="Latitude" />
    <asp:BoundField DataField="Longitude" HeaderText="Longitude" />
</Columns>

C#

protected void gvAlerts_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
      GridViewRow row = gvAlerts.Rows[e.RowIndex];
      string Latitude = ((TextBox)(row.Cells[1].Controls[0])).Text;
      string Longitude = ((TextBox)(row.Cells[2].Controls[0])).Text;           
}

Here in latitude and longitude, i am getting the old values only....not getting the newly entered values.....
why it is getting old values only?

How you bind the GridView ? Please post theat code here.

<asp:GridView ID="gvAlerts" runat="server" DataKeyNames="UserAlertId" AutoGenerateColumns="false" AutoGenerateDeleteButton="true" OnRowUpdating="gvAlerts_RowUpdating" OnRowEditing="gvAlerts_RowEditing" OnRowCancelingEdit="gvAlerts_RowCancelingEdit" OnRowDeleting="gvAlerts_RowDeleting" AutoGenerateEditButton="true">

<columns>

<asp:BoundField DataField="latitude" HeaderText="Latitude" />

<asp:BoundField DataField="Longitude" HeaderText="Longitude" />

<asp:BoundField DataField="AlertName" HeaderText="AlertName" />

Dear Friend,

In gridview rowupdating event, the row is not actually updated. It handles the event for the row before updates.

Please go through the link below; you will get to know the problem in your code.

GridView.RowUpdating Event

Please don't forget to mark this as your answer if it helps you out.

It is a PostBack issue. Please check my answer. RowUpdating should fetch you the new values.

I think when you click update link, Gridview is binding again before taking new value.

You must have forgotten to use if(!IsPostBack) before GridView.DataBind().

Ideally before binding you should check that like below...

C#

if(!IsPostBack)
{
    // Code to bind the GridView.
}
