DataGrid asp.net/vb.net radio button

Trampas

Hi all,

I am using using ASP.NET 2 and VB.Net 2005.

I have a radio button column on the grid.

When a person its the submit button I am trying to find out what row is selected on the DataGrid.

I have the following code but it keeps coming back with nothing

ASP.NET

<asp:DataGrid ID="dtgDetails" runat="server" AutoGenerateColumns="false">
                    <Columns>
                        <asp:TemplateColumn >
                            <ItemTemplate >
                                <asp:RadioButton id="OutRadioInfo" runat="server" value='<%# Eval("RadioInfo") %>'  />
                            </ItemTemplate>
                        </asp:TemplateColumn>
                        <asp:BoundColumn DataField="Day" HeaderText="Day"/>
                        <asp:BoundColumn DataField="Date" HeaderText="Date"/>
                        <asp:BoundColumn DataField="Month" HeaderText="Month" />
                        <asp:BoundColumn DataField="DeptTime" HeaderText="Departure Time" />
                        <asp:BoundColumn DataField="ArriveTime" HeaderText="Arrival Time" />
                        <asp:BoundColumn DataField="Price" HeaderText="Price" />
                        <asp:BoundColumn DataField="RadioInfo" HeaderText="RadioInfo"/> 
                    </Columns>                  
                </asp:DataGrid>

VB.NET

Protected Sub Purchase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Purchase.Click

Dim selectedValue As String = Request.Form("OutRadioInfo")

End Sub

Thanks

is it possible for you to approach it a slightly different way? What you could do is have a select column instead of the radio one, this will select a row and submit allowing you to trap the rowselected event.

I'm pretty new to asp but this is how I check for selected check boxes, I imagine its pretty similar for radio buttons:

Sub Check(sender As Object, e As EventArgs)
Dim chkSelected As CheckBox
Dim dgi As DataGridItem
for each dgi in MyDataGrid.Items
chkSelected = dgi.FindControl("mycheckbox")
If chkSelected.Checked Then
dgi.Cells(5).Text = "Checked"
else
dgi.Cells(5).Text ="Not Checked"
end if
next
End Sub

<asp:TemplateColumn HeaderText="Check Box column">
<ItemTemplate>
<asp:CheckBox id="mycheckbox" AutoPostBack="True" OnCheckedChanged="Check" runat="server" />
</ItemTemplate>
</asp:TemplateColumn>

I changed it from a DataGrid to a DataView

You can do this in the SelectedIndexChanging event for the datagrid

Dim gvrRowDetails As GridViewRow

grvRowDetails = dgr.Rows(Me.dgr.SelectedIndex)
blChk = grvRowDetails.FindControl("chkbox")
