Using a custom ExpressionBuilder doesnt seem to work with ParseControl (dynamically adding controls, that are using the custom ExpressionBuilder)
Works fine with the build-in Resources ExpressionBuilder though.
Anyone have a solution/workaround for this?
Or even an explanation for why it doesnt work.
Example
protected void Page_Load(object sender, EventArgs e) {
string s = (@"
<hr />
1: <asp:Label ID=""Label1"" Text=""<%$ Resources:language, Greeting %>"" runat=""server"" />
<br />
2: <asp:Label ID=""Label2"" Text=""<%$ IHLPResource:Greeting %>"" runat=""server"" />
<hr />
");
Control ctrl = ParseControl(s);
Page.Form.Controls.Add(ctrl);
}
1: Gets rendered just fine, while 2: fails (no error, the value just doesnt get rendered)
ie. the output is:
1: Hi
2:
(2: should say "\\\Output from custom ExpressionBuilder///" - See code below)
If I simply add the above to the aspx page, it works fine (ie. my custom ExpressionBuilder is not the cause of failure)

Hi
when I click on lnkAddTraveller link it always needs 2 times click on this link to execute lnkAddTraveller_Command event block.
How can I solve this problem.
lnkAddTraveler.Command += new CommandEventHandler(lnkAddTraveller_Command);
lnkAddTraveler.CommandName = "Hotel," + dtHotelInfo.Rows[i]["Id"].ToString() + "," + dtHotelInfo.Rows[i]["HotelID"].ToString();
private void lnkAddTraveller_Command(object sender, CommandEventArgs e)
{
//Code here
}
thanks

I want to show all the dates of the current week on the page_load event .How can i do this.
Can any one help me.
Regards

|
|
|

This will give you all the dates in the current week - you will need to adfjust it depending on what your starting day is, this assumes Monday.
DateTime curr;
DateTime start = DateTime.Now.AddDays((int)DateTime.Now.DayOfWeek * -1);
for (int c = 1; c < 8; c++)
{
curr = start.AddDays(c);
}

To which exchange server do you want to connect? Exchage server 2003 or 2007.
if your are trying to access Exchange 2007 Server, then you can able to do it easily. becuase Exchange 2007 provide Webservices for same (EWS ) . But its not possible using Exchange 2003, because it does not provide any such API's
Check This[^]

In which form Information passed from one ASP.NET page to another.
|
|
|
|
|
There are many ways to pass information from one page to another page like Querystring,session etc.
What do u exactly want to know?
|
|
|
|
|
Having looked at a couple of your questions here, i'd suggest maybe a book on ASP.net, or some tutorials (see www.asp.net).
This is fairly fundamental stuff, you'll need a decent grounding in it for any ASP.net development.

foreach (DateTime selectedDate in theDates)
txtsun.Text = theDates[0].ToString("MM/dd/yyyy");
txtmon.Text = theDates[1].ToString("MM/dd/yyyy");
txttue.Text = theDates[2].ToString("MM/dd/yyyy");
txtwed.Text = theDates[3].ToString("MM/dd/yyyy");
txtthru.Text = theDates[4].ToString("MM/dd/yyyy");
txtfri.Text = theDates[5].ToString("MM/dd/yyyy");
txtsat.Text = theDates[6].ToString("MM/dd/yyyy");
It is working fine.
But i want the same output on page_load event also.how can i get this. can anyone help me.

I don't quite understand - you want the values selected by a user in a calendar control, but in the page load event?
|
|
|
|
|
Should be obvious - its for Psychics Anonymous, they did the selection before they went to the web site

how Find out Serial No of HDD who access my Web Application.I m using System.Management Namespace to Find the Client Mechine.This Application run on when it was running in Visual Studio.net (IDE) Envoirnment but when it was running on web server it is still nothing given to Response.
what is Problem
|

|
|

A web app cannot access the client in this way, it would be a wonderful way of spreading malware. It will work through the IDE as you are running on your localhost.
