how to make a control that can have controls nested inside it. I've made a jQuery tab browser class which uses a hidden field to remember which tab is selected and create the relevant client script to re-select it on postback...it works fine...
This is for web part development so all controls are created dynamically.
The problem is when I add a control to one of the tabs, the values set in that control disappear on postback..I understand there is a lot of information about user controls, viewstate and control state but nothing seems to give me access to those values...
I've boiled it right down to the basics and still can't get it to work unless the custom control has all its controls added in OnInit...which is bad news for me because I need to instantiate the browser, the use a 'AddTab' method to add tabs and controls to them, which occurs after the OnInit event and therefore I can't access the postback values!!
I get the feeling I'm missing something big here, I must be lol...here's is an example:
[Code]....
These controls have to be dynamically created, so I didn't see the need to make the ascx user controls..
I have a requirement as mentioned below: 1. There is a gridview containing a linkbutton field (lnkgdvMerchant)in one of the column defination as menioned in the mark up below :Please note the bolded line of code for more details.

I want to create a gridview with checkboxes. (only vb.net)
1) persist checkbox rows in paging in vb.net not c#
2) add the checked rows to datatable datasource and show on next page in paging
I set the Databinding of a repeater to a list of classes i.e. List<Message>, I have used the ItemCommand event before to pull out individual ID's etc based on the CommandArgument, however is it possible to make the class itself the CommandArgument instead of one of its properties, this way I have them all at my disposal.For example say I have a list of messages and within the repeater I have this:
[Code]....
However I want to pass the Message class as the argument instead, can this be done?
Alright, so here's my basic ASP.NET page setup: I've got a page with a GridView that has ContentTemplates in it. You can add a row and edit/remove rows at any time. There's a "New" button that creates a new row.
All of this data is bound to custom data objects. So if I have a GridView of "People" and each row has "FirstName", "LastName", and "Gender" (with TextBox and DropDown controls), I then have a "Person" object which has public properties for "FirstName", "LastName", etc. I have the binding set up correctly, and I can push data into the GridView from the object, and I persist the object with the Session variable. My page lifetime structure looks something like this:
Page_Load: Loads the List(Of Person) from Session()
Any events fire, and modify the List(Of Person).After any event, the List(Of Person) gets saved back into Session(), and is then DataBound to the GridView (and any subsequent fields are also DataBound, such as the DropDownList.
My question is: Whenever I fill in rows in the GridView, and then add a new row (there is no database saving going on whatsoever), my fields clear out and don't persist across PostBacks. So, how can I persist my custom data objects with databinding across postbacks?
I have a control (say, a DataGrid or a ComboBox) which is a child of a user control. I want to DataBind it on every request, rather than have it's state persist through ViewState. I need to leave EnableViewState=true however. This means, I think, that I need to call DataBind before TrackViewState() is called.
I read the fantastic blog post TRULY Understanding ViewState and it answers my question in 4. Initializing child controls programmatically. However, the article's solutions are less-than-ideal: create child controls dynamically (I'm not and can't -- too much existing code), use a 3rd party CodeExpressionBuilder (would much prefer this was in code-behind), and use OnPreInit (which "doesn't help you what-so-ever if you are developing a CONTROL").

I am building a WCF Web Service that has a Business Logic layer (that implements all validation logic and other business rules) and a Data Access Layer that makes calls to Stored Procedures in my database.
I would like to be able to validate the length of data passed against that of the length of the parameters in the Stored Procedures without having to explicitly define the parameter lengths in my WCF Web Service.
Eg:
Person Object
Person.Name = "John Dhoe"
Person.Age = 37
SQL Stored Procedure
SavePerson
FullName Varchar(15)
Age Int
In my BLL or DAL, I would like to be able to do something like :
If(Person.Name.length == SavePerson.Parameters["FullName"].Length)
{
Return true;
}
else
{
Return false;
}
Has anyone tried this out before? Is this even possible?
