Events of child gridview are not executed

[Guest]

I have a perent gridview which includes in a template field a child gridview.
Child gridview includes command buttons for opening different windows based
on its row selected.

I used the code below. The event for RowDataBound is executed, rows get
different color, but event for RowCommand is not executed. What could be the
problem ?

Thanks a lot in advance.

<asp:GridView ID="grv_batches" runat="server"
AutoGenerateColumns="False" DataKeyNames="country_no,product_no,client_no"
CssClass="GridView" >
<Columns>
<asp:ButtonField CommandName="Send" Text="Finish" >
<ControlStyle CssClass="GridView_LinkButtons" />
</asp:ButtonField>
<asp:BoundField DataField="Country_name" HeaderText="Country" />
<asp:BoundField DataField="product_name" HeaderText="Product" />
<asp:BoundField DataField="client_name" HeaderText="Company" />
<asp:TemplateField HeaderText="Details">
<ItemTemplate>
<asp:GridView ID="grv_reports" runat="server"
AutoGenerateColumns="False" CssClass="GridView"
OnRowCommand="grv_subscr_reports_RowCommand"
OnRowDataBound="grv_subscr_reports_RowDataBound">
<Columns>
<asp:ButtonField CommandName="Sub" Text="S">
<ControlStyle
CssClass="GridView_LinkButtons" />
</asp:ButtonField>

Protected Sub grv_subscr_reports_RowCommand(ByVal sender As Object, ByVal
e As System.Web.UI.WebControls.GridViewCommandEventArgs)
If e.CommandName = "Sub" Then

Protected Sub grv_subscr_reports_RowDataBound(ByVal sender As Object,
ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
Select Case e.Row.Cells(11).Text 'report status
Case "New"
e.Row.BackColor = Drawing.Color.LightGreen

Show us how you bind the data. I suspect the data for internal data grid is
being
re-bound on every postback so rowcommand event won't be raised.

Thanks Milosz for your message.

Here is the code:

My parent gridview is binded in btn_show button, because user select the
countries, products, clients for showing the data in parent gridview which
then refreshes the child gridview.

Protected Sub btn_show_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btn_show.Click


refresh_gridview_data()


End Sub


Protected Sub refresh_gridview_data()

dbo.Report.product_no, dbo.Report.client_no, "


sdsc.SelectCommand = var_SQL


grv_batches.DataSource = sdsc
grv_batches.DataBind()


End Sub

Hi there again,

You're re-binding internal gridview on every postback inside rowcreated
event. Move internal grid data binding to rowdatabound event and everything
will be OK:

Protected Sub grv_batches_RowDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.GridViewRowEventArgs) Handles
grv_batches.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim sdsc As New SqlDataSource
Dim grv_rep As GridView = e.Row.FindControl("grv_reports")


sdsc.ConnectionString =
ConfigurationManager.ConnectionStrings("ConnectionString1").ConnectionStringsdsc.SelectCommandType =
SqlDataSourceCommandType.StoredProcedure()
sdsc.SelectCommand = "STP_slct_Reports"


sdsc.SelectParameters.Add("country_no",
grv_batches.DataKeys(e.Row.RowIndex).Values("country_no"))
sdsc.SelectParameters.Add("product_no",
grv_batches.DataKeys(e.Row.RowIndex).Values("product_no"))
sdsc.SelectParameters.Add("client_no",
grv_batches.DataKeys(e.Row.RowIndex).Values("client_no"))

grv_rep.DataSource = sdsc
grv_rep.DataBind()
End If
End Sub


Hope it helps
