I am using ASP .Net 2.0 with VB. I have a page with 4 radio buttons, a grid and a repeater and a gridview inside the repeater. Right now the gridview inside the repeater uses a field from the first grid to pass into the data source.

   
     <asp:GridView ID="gvWaterLevels" AutoGenerateColumns='false' runat="Server"
                      DataSource='<%# GetWaterLevels(CType(Eval("strSiteId"), string)) %>'>

 

What I need to do is evaluate the Radio buttons in a javascript and pass the return of the JavaScript to the method GetWaterLevels(); or Somehow figure out which radio button is selected and pass it to the GetWaterlevels() method

Here is the Javascript. 

function TimePeriod()
{
    var rbPeriod = document.getElementById("rbPeriod");
    var rbfive= document.getElementById("rbfive");
    var rbTen = document.getElementById("rbTen");
    var rbFifteen = document.getElementById("rbFifteen");
    var rbTwenty = document.getElementById("rbTwenty");
    
    if (rbPeriod.Checked)
    {
    Return 0;
    }
    if (rbfive.Checked)
    {
    Return 5;
    }
    if (rbTen.Checked)
    {
    Return 10;
    }
    if (rbFifteen.Checked)
    {
    Return 15;
    }
    if (rbTwenty.Checked)
    {
    Return 20;
    }
}

Please Let me know my other options. Is there a CodeBehind way to Set Repeater Datasource from the first grid?

Hi kramer9802,

You can handle ItemDataBound event of Repeater to pass value to the function.

Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)
    If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then
        Dim gv As GridView = DirectCast(e.Item.FindControl("gvWaterLevels"), GridView)
        Dim strSiteId As String = DirectCast(e.Item.DataItem, System.Data.DataRowView)("strSiteId").ToString()
        Dim TimePeriod As String = ""
        Dim rbPeriod As New RadioButton()
        If rbPeriod.Checked Then
            TimePeriod = "0"
        ElseIf rbfive.Checked Then
            TimePeriod = "5"
        End If
        'check other RadioButton
        gv.DataSource = GetWaterLevels(strSiteId, TimePeriod)
        'input values to function
        gv.DataBind()
    End If
End Sub

Just my example, change your own id and variables.

Thanks,

That worked great! Thanks.
