Handle RadioButton event in edit mode

[Roberto Wenzel]

Hello guys.
In my data grid edit form i have a RadioButtonList (which is not binded to a grid column!) and a radUpload control which is disabled by default.
I would like to have this radUpload control beeing enabled depending on the selected radio button.
I mean: the user selects an option and depending on his choose the radUpload control is enabled or disabled immediately.
Which settings do i have to make in the AJAX Manager? Where to handle the event in my VB ocde? How to update the edit form?
Any help is appreciated.
Cheers Roberto

Hello Roberto,

Try accessing the RadUpload in the SelectedIndexChanged event of the RadioButtonList and set it enabled/disabled according to the RadioButtonList text. To understand better check out the code below:
cs:

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        RadioButtonList radbtnlist = (RadioButtonList)sender;
        GridEditableItem editItem = (GridEditableItem)radbtnlist.NamingContainer;
        RadUpload rdupload= (RadUpload)editItem.FindControl("FileUpload");
        string strtxt = radbtnlist.Text;
        if (strtxt == "Replace file")
        {
            rdupload.Enabled = true;
        }
        else
        {
            rdupload.Enabled = false;
        }
    }

Thanks
Princy.

Hello,
that's it. Thanks a lot.
Here is my code in VB.
I added  ...OnSelectedIndexChanged="RadioChanged".. in ASPX for the RadioButtonList and the following code.

    Public Sub RadioChanged(ByVal sender As Object, ByVal e As EventArgs)
        Dim radbtnlist As RadioButtonList = sender
        Dim editItem As GridEditableItem = CType(CType(sender, RadioButtonList).NamingContainer, GridEditableItem)
        Dim radup As RadUpload = editItem.FindControl("FileUpload")
        Dim stext As String = radbtnlist.Text
        If stext = "Replace file" Then
            radup.Enabled = True
        Else
            radup.Enabled = False
        End If
End Sub
