asp.net datagrid control: Add a new record in GridView -- asp.net datagrid control

Hi Walter,
from the working example you gave me, what is the VB.NET equivalent of
Controls[0].Controls[0]?
GridView1.Controls[0].Controls[0].GetType().Name or
GridView1.Controls[0].Controls[0].FindControl("tbEmptyInsert")

The problem I found in using EmptyDataTemplate is how to access labels and
textboxes in that section, like I do in FooterRowTemplate.
Thank you.

Hi Bruno,

What exactly problems are you getting when using EmptyDataTemplate?

You may take a look at
http://geekswithblogs.net/casualjim/archive/2006/05/04/77151.aspx for a
working example on how to use this feature.

Please tell me what do you think of this solution, I would be glad to
continue work with you if you need anything else.

Sincerely,

Hi Bruno,

Just use GridView1.Controls(0).Controls(0). Following is the complete code
listing of VB.NET equivalent of the example:

Imports System.Data

Partial Class Default3
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
If Not IsPostBack Then
Dim dt As New DataTable
Dim dc As New DataColumn("Name")
dt.Columns.Add(dc)
Dim dr As DataRow = dt.NewRow()
dr("Name") = "Ivan"

GridView1.DataSource = dt
GridView1.DataBind()
End If

RecurseControls(GridView1.Controls(0).Controls)
Label1.Text += GridView1.Controls(0).Controls(0).GetType().Name +
" "
End Sub

Sub RecurseControls(ByVal ctls As ControlCollection)
For Each ctl As Control In ctls
If Not ctl.HasControls() Then
Label1.Text += ctl.ClientID + " " + ctl.GetType().Name +
" "
Else
RecurseControls(ctl.Controls)
End If
Next
End Sub

Protected Sub GridView1_RowCommand1(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.GridViewCommandEventArgs) Handles
GridView1.RowCommand
If e.CommandName = "EmptyInsert" Then
Dim tbEmptyInsert As TextBox =
GridView1.Controls(0).Controls(0).FindControl("tbEmptyInsert")
Label1.Text = String.Format("You would have inserted the name:
{0} from the emptydatatemplate", tbEmptyInsert.Text)
End If
If e.CommandName = "Insert" Then
Dim tbInsert As TextBox =
GridView1.FooterRow.FindControl("tbInsert")
Label1.Text = String.Format("You would have inserted the name:
{0} from the footerrow", tbInsert.Text)
End If
End Sub
End Class

I hope this helps. Please feel free to post here if anything is unclear.

I don't know way I found problems the first time I used
GridView1.Controls(0).Controls(0) as you suggested me. it's my fault.
Your sample helped me.
Thank you Walter.

If there is no row matched Add a Empty row to the second table dataset and
bind the dataset to Datagrid now the new blank row will be added ..
