Greetings!
I have a DropDownList within a FormView which are bound to XmlDataSources:
<%# XPath("SomeNode")%>
' />
In the page's codebehind, I have the following OnLoad() method as well as the method for when the select index of the dropdownlist changes:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (!IsPostBack)
{
string xml = GetMyXml(0); // default value
MyXmlDataSource.Data = xml;
MyDdlDataSource.Data = xml;
}
}
protected void MyDdl_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList l_MyDdl = FindControl("MyDdl") as DropDownList;
int myVal;
if (l_MyDdl != null)
if (!Int32.TryParse(l_MyDdl.SelectedItem.Value, out myVal))
myVal = 0;
string xml = GetMyXml(myVal);
MyXmlDataSource.Data = xml;
MyDdlDataSource.Data = xml;
}
When a different value is selected from the dropdown list and SelectedIndexChanged is invoked, I am unable to get the value of the dropdown list (FindControl always returns null) in order to use it to re-bind the datasources. How can I get this value?
