Which radiobutton are you using? I mean, server controls or just HTML control? I think if you are using the server control, you should not have that problem.. However, in order to solve this, I suggest you to store the radiobutton value in cache or session and set it back in pageload...

Hi all,

calendarDateOfBirth.SelectedDate = Convert.ToDateTime(_member.DateOfBirth)
how do you make the calander display this selected date now??? i know the date is correct but i dont know how to display it on the calander?
I can write the value to the database and it works fine with the correct value i just dont know how to display it... please help

How do you want to display it ? What calendar control are you using ? Why doesn't the SelectedDate property solve your problem ? Is Convert.ToDateTime working ?

i think the convert is working...
the thing is... calDateOfBirth.SelectedDate = Convert.ToDateTime(_member.DateOfBirth.ToString());
the date is set correctly on the calender... i can click on the previouse month arrow up to the correct month and see the selected date (as the correct date). When the page is loaded it is displaying the today date not the selected date? how do you specify to show the selected date on the calender itself like it is showing the current date???

ha ha, never mind... i figured it out...
right after this section of code:
calDateOfBirth.SelectedDate = Convert.ToDateTime(_member.DateOfBirth.ToString());code> i have added this:<br />
<br />
<code>calDateOfBirth.VisibleDate = calDateOfBirth.SelectedDate;
it is working fine now  Thank you for your time any way.

try setting VisibleDate as well asa SelectedDate (you would assume that VisibleDate is set to SelectedDate but it isnt by default!)

You include the css in your form, and if you used named classes, you set the class names of the controls.

Hai,
Can anybody give me the code snippet for the tree view to be get populated with xml nodes.
Eg. Say i am having an xml file that contains information about one book. And i want to add the chapter's headings and the sections headings in the tree view .

This is the error while i tried to bind the xml file with treeview
HierarchicalDataBoundControl only accepts data sources that implement IHierarchicalDataSource or IHierarchicalEnumerable.
My code is
DataSet ds = new DataSet();<br />
ds.ReadXml(Server.MapPath("xmlfile.xml"));<br />
<br />
TreeView1.DataSource = ds;<br />
TreeView1.DataBind();
My xml file contents are
<?xmlversion = "1.0" encoding="utf-8" ?>
<countries>
<country>
<text>Norway</text>
<value>N</value>
</country>
</countries>

Error message explains itself the problem. Check this[^] for more information. Or you can use XMLDataSource too.

DataSet aDataSet = new DataSet();
aDataSet.ReadXml(new StringReader(aXmlDoc.OuterXml));
the refered[^] article contains the above code.
i am unable to understand , how can i invoke the OuterXml ,
it is not appearing in the control properties(xml data source)

I have never used this one. So I don't have any good links. Isn't that MSDN example works ?

No ,Actually i was trying to insert delete the recors dynamically.
do u have one such link?
and one ore thing ,
i have a Command Field control , on clickig the update button , i have to validate the textbox , having the date information, Initially i used the regular expression , but the moment i wrote 30/2/2000 (dd/mm/yyyy), it did not validate , that's y i prefered to use the java script,
how should i find out programically the update button of command field , in order to validate the date .

I know I've told you this at least 15 times, but why wouldn't you use sensible variable names ?
I've never used a TreeView control in ASP.NET, but your error message gave me an interface name, and by typing it in to google, I discovered that you need to set up an XmlDataSource in order to use XML to bind to a tree view.
