Forms Data Controls :: DataList Doesn't Load Some Of The Times?
Sep 13, 2010
This is the problem. My datalist, which connects to an Objectdatasource (I implemented custom paging) becomes populated with data only half of the time. When I go to the aspx page which contains that datalist (from another page), sometimes, the datalist fully loads, but sometimes only the header shows up. The header just contains hard-coded text whereas the body (itemtemplate portion) contains things that are binded to the objectdatasource. I thought I would mention this since the problem might have something to do with how things in asp.net bind.
The strange part of this is that when I was testing and debugging within VWD 2010, the datalist loaded fully everytime and I had no issues. When I placed my files on the IIS web server, this is when the problems started happening.What could the problem be? The speed of the IIS web server vs VWD's "internal server"? My page_load, init_load, etc methods are empty for this aspx page. The datalist is solely handled by the objectdatasource_selecting method. Should I explicit call something from one of those early lifecycle methods to ensure proper datalist loading?

I have a simple UserControl that I've created that simply allows a user to enter the date. For the time being, it has a single Textbox with ID="tbDate". I am trying to dynamically add this control multiple times via (for example) `placeholder.Controls.Add(LoadControl())` but am receiving the error "An entry with the same key already exists". I could, perhaps, change the ID of the elements but then it would be difficult to grab the value entered by the user.

I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?

I have a datalist and want the results paged I have written a pager.ascx page and have an aspx and aspx.cs page to display the results. I have a stored procedure to pull the data out of the database and a class to talk between the stored procedure and presentation controls I have the pager being displayed when the results get over the limit I have set to 10 in the web.config file but when i click on the next link to display the next page of results it doesn't do anything. my aspx page is
<uc1:Pager ID="topPager" runat="server" Visible="False" />
<asp:DataList ID="newsList" runat="server" CssClass="List" align="center">
<ItemStyle CssClass="ItemList" />
<ItemTemplate>
<h2><%# Eval("Title") %></h2>
<p>Posted <%# Eval("Date") %></p>
<p><%# Eval("News").ToString().Replace("
", "<br />") %></p>
</ItemTemplate>
</asp:DataList>
<uc1:Pager ID="bottomPager" runat="server" Visible="False" />
my aspx.cs page is
protected void Page_Load(object sender, EventArgs e)
{
// Retreive page from the query string
string page = Request.QueryString["Page"];
if (page == null) page = "1";
// How many pages of posts
int howManyPages = 1;
// pager links format
string firstPageUrl = "";
string pagerFormat = "";
//DataAccess.GetNews returns a DataTable object containing news data which is read into datalist
newsList.DataSource = DataAccess.GetNews(page, out howManyPages);
// Bind the data to the data source
newsList.DataBind();
// have the current page as interger
int currentPage = Int32.Parse(page);
// Display pager controls
topPager.Show(int.Parse(page), howManyPages, firstPageUrl, pagerFormat, false);
bottomPager.Show(int.Parse(page), howManyPages, firstPageUrl, pagerFormat, true);
}
my pager.ascx page is

I have the follow code (i just listed the parts that might be the more important to understand my problem):
(Code Behind)
[Code]....
(Page .ascx)
[Code]....
The user control RatingControl shows the rating and the number of rates, the user control Pager is responsible for raising CurrentPageChanged when the page changes and BindData() is a function
that binds data to the Datalist control.
When the page is loaded for the first time BindData() marked with ** is executed , thereafter i only want to load data when the event CurrenPageChanged raises.
So far so good, but the problem is when the CurrentPageChanged is raised and call the BindData() function, the user controls are not loaded properly, and things that i can't understand happen, like the user controls not receiving the properties initialized when they are loaded, but the other controls inside the Datalist like lblDescription are loaded correctly with their data.
Summarizing, the user controls are not loaded correctly in this particular case when the DataBind() is called by an event.
I already searched in the internet, and i read about page life cycle, user controls and i still didn't understand why this happens and how to fix it.

I am experimenting with 3 dropdowns bound to 3 different datasources. I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this.
<asp:DropDownList ID="DropDownList_CostCentres" runat="server" Height="16px"
Width="138px" DataSourceID="CostCentreDataSource" DataTextField="CostCentre"
DataValueField="CostCentreID">
</asp:DropDownList>
<asp:SqlDataSource ID="CostCentreDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [CostCentreID], [CostCentre] FROM [CostCentres]">
</asp:SqlDataSource>
<br />
<br />
<asp:Label ID="Label2" runat="server" Text="Manager:" Font-Bold="True"></asp:Label>
<br />
<asp:DropDownList ID="DropDownList_Managers" runat="server" Height="16px"
Width="138px" DataSourceID="ManagerDataSource" DataTextField="EmployeeName"
DataValueField="EmployeeID">
</asp:DropDownList>
<asp:SqlDataSource ID="ManagerDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Employees] WHERE ([CostCentre] = @CostCentre)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_CostCentres" Name="CostCentre"
PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
However, the second dropdown does not load with the relevant data when I select a value from the first dropdown (stays blank). Must I still provide an event handler and how do I combine this with the sqldatasource?

I've got a few labels in a datalist that are being populated based on the values of a queryString but without the query string the datalist is empty.
How can I access the labels in the datalist and set a default value to them on the load of the page?

am using a master page, with children pages.
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.

I have a data grid in which I have to display around 12,000 records. Even if I do paging it is difficult to display all the records. Is there any other control or something else so that I can display all these records. Even if I make these as alphabetical also, some times I have to load 1000 records in a page which is difficult.

I created a search page with a lot of different functions. The page takes about 6 seconds to load so I'd like to work on making it faster. I first want to see what functions are taking the most time. I originally tried adding Response.Write(Date.Now()) throughout the code but didn't yield accurate results. I'm guessing it that's because .NET doesn't compile things linearly?
