Hello!
I have a page with a datagrid, where the user can select
an item. Based on the selection of the user, a xml-file is
generated. Some values of the xml-file should be passed to
an application via javascript.
This is what I have done:
--- the source file ---
private void DataGrid1_SelectedIndexChanged(object sender,
System.EventArgs e)
{
// generate MyDocument.xml
string scriptString = "\n<script language=\"javascript\"
id=\"execCodeJS\">\n" +
"doSomething();\n</script>\n";
if (IsClientScriptBlockRegistered("execCodeJS") == false)
{
this.RegisterClientScriptBlock("execCodeJS",
scriptString);
}
}
------
--- the aspx page ---
<xml id="selectionXML" src="MyDocument.xml" />
<script language="javascript" id="clientEventHandlersJS">
function doSomething()
{
var xmlNode;
xmlNode = selectionXML.XMLDocument.selectSingleNode
("these/and_that"); +
alert(xmlNode.text);
}
</script>
------
Unfortunately this does not work.
---
Error: the data necessary to complete this operation is
not yet available.
---
When clicking a button with onclick="doSomething()", the
problem does not occur, everything works fine.
The user selection in the datagrid triggers an event
function.
---
function __doPostBack(eventTarget, eventArgument)
{
// these and that...
theform.submit(); // -> DataGrid1_SelectedIndexChanged
is called
}
---
The following event function would solve my problem:
---
function __doPostBack(eventTarget, eventArgument)
{
// these and that...
theform.submit(); // -> DataGrid1_SelectedIndexChanged
is called
doSomething(); // calling my code
}
---
But how can I get this done?
I am relatively new into web programming, so if there is
better way for solving my problem, please tell me.
Thanks in advance,

No, have not resolved this issue. So I'm reposting my request
