Question

I have a datebox user control in grid view and one of the properties is RowID. From Gridview I am passing the Row ID to the datebox as

<uc2:datePage1 ID="txtSubToSA" RowID=<%# Container.DataItemIndex %>   runat="server" Enabled="true" Text= '<%#Eval("SUBMITTED_TO_SA") %>' />

in the pageload of the usercontrol I am adding attribute to call a javascript function like this:

protected void Page_Load(object sender, EventArgs e)
    {

        txtDate.Attributes.Add("onchange", "getRow(" + RowID + ")");

    }
  public int RowID
        {
            get;
            set;
        }

Now when I make a change in the datebox of the gridview, no matter what row it is it always gives takes RowID of 0 and do not recognize changes I made in other rows. What is it that I am doing wrong here?

Answer 1

You’re adding the onchange attribute in the Load event handler, before the RowId has been set – which will happend during databinding. You could perhaps override DataBind and set the attribute after databinding is complete:

public override void DataBind()
{
    base.DataBind();
    txtDate.Attributes.Add(...);
}
