I have a datagrid with textboxes on it that are bound. Displaying the data pulled from the db works. But when a user updates a textbox I am unable to extract that data. I have tried a few options I have found involving using CType. Below is part of the code )(let me know if you need more as I a newbie at .net development). Thanks for your help.

<form name="form1">
    <div align="center"><strong>Run Date</strong> 
      <input type="text" value="<%# IIf((Request.QueryString("dt") <> Nothing), Request.QueryString("dt"), FORMATDATETIME(NOW(),2)) %>" name="DT" size="10" onChange="ValidateForm();">
      <input type="submit" value="Refresh" name="ref">
    </div>
</form>

<form runat="server">
  <div align="left">
      <asp:Button ID="butt" runat="server" Text="Add Runs" OnClick="InsertRun" />     
  </div>
  <asp:DataGrid AllowPaging="false" 
  AllowSorting="false" 
  AutoGenerateColumns="false" 
  CellPadding="3" 
  CellSpacing="0" 
  DataSource="<%# DataSet1.DefaultView %>" id="DataGrid1" 
  runat="server" 
  ShowFooter="false" 
  ShowHeader="true" OnItemCreated="colorrow"

        <asp:TemplateColumn HeaderText="Run Notes"

      <ItemTemplate>

         </ItemTemplate>

Here is where I try to extract the data (there are a couple options (runNotes and runNum):

Dim aa As TextBox = CType(Me.DataGrid1.Items(i).FindControl("runNotesTxt"), TextBox)
                runNotes = aa.Text
                Dim bb As TextBox = CType(Me.DataGrid1.Items(i).FindControl("runNumTxt"), TextBox)
                runNum = bb.Text
                
                runNum = CType(Me.DataGrid1.Items(i).Cells(3).FindControl("runNumTxt"), TextBox).Text
