How to handle events of Usercontrol(containing dropdownlist on .ascx page) on .aspx page.I am having a button on .aspx page.When I click on button ,i want to retrieve the value of selected dropdownlist item.I have used LoadControl() method to loasd the usercontrol on .aspx page.If possible try to explain me with example.
In the usercontrol expose the selectedValue of the dropdownlist in a Public property on the UserControl. That way in the aspx page you can just do:
userControl.Publicproperty where userControl is the name of your UserControl variable and Publicproperty is what you named the SelectedValue of the Dropdown. The PublicProperty would probably be readonly with only a Get that points to dropdownlist.SelectedValue.
I'm writing a web application which extensively uses the Cache. Now I'd like to get an overview over all cached objects and their sizes in bytes. Does anyone know how to retrieve the size of an object in memory?
So far I've googled but didn't come up with something useful. Most answers were like 'you can't get the size...'. Btw, I'm using .net 1.1.
If it is not possible, is there a way to get the amount of memory the Cache is using altogether?
Any help is greatly appreceated.

I made a DataList with an SqlDataSource and FormView (with a label in) inside it. I used FindControl to get to the SqlDataSource and FormView to alter their properties, but when I do the same for the Label inside the FormView it just comes back with an error: "Object reference not set to an instance of an object."
The code I have is:
Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As DataListItemEventArgs) Handles DataList1.ItemDataBound
If e.Item.ItemType = ListItemType.Item Or ListItemType.AlternatingItem Then
Dim FormView1 As FormView = CType(e.Item.FindControl("FormView1"), FormView)
FormView1.Visible = True
'This part works alrigh (I think)
'I must have made an error in the following code.
If FormView1.CurrentMode = FormViewMode.ReadOnly Then
Dim LabelRating As Label = CType(FormView1.Row.FindControl("lblRating"), Label)
I'm really sorry to be annoying, but I would really appreciate some help with this one.
DataList is just like DataRepeater but with additional functionalities.
and additinal templates for formating.We can have custom paging inDataList. But no in bulit paging But where as in DataGrid there isin built paging ,sorting,editiong,which reduces lot of cod e on developer. Its better to use repater control if performance only the criteria.
Since Grid and Lsit Takes round trip than Repeater .
Features of Datagrid
(1)Displays data as a table
(6)Colors, font, borders, etc.
(9)Item as row
Features of Repeater
•No default output
•Item as row
Features of DataList
•Good for columns
•Item as cell
i have created multilingual pages in asp.net,one for english and one for urdu.the urdu pg is created by copying the resource file of english pg nad pasting it in the local resource.on the button click i have called an InitilizeCulture method in which if english is set by default to chnnge it to urdu it throws an exception on this line:
where currentlang is currently set to urdu.
and the exception is:
System.NotSupportedException: Culture 'ur' is a neutral culture. It cannot be used in formatting and parsing and therefore cannot be set as the thread's current culture.
in a scenario i have an application to be developed few parts(web pages) using .net 1.1 and few parts(web pages)using .net 2.0.
so what and where will be the setting.
can anybody guide me by sending code if possible.
thanks a lot
A single we site can not have mixed pages. You will have to have two web sites. One that runs on .net 1.1 and another that runs on .net 2.0. I would think seriously of switching the web site to one .net version. Otherwise I think you are asking for problems.
