C# - How To Define Variable In Repeater
Jan 26, 2010
I like to handle and compare a lot of date times in my repeater even I have to work more than one time with the same.
It's a bit ugly, to cast everywhere the Eval("MyDate") like ((DateTime)Eval("MyDate")) to substract 2 datetimes or to compare it, even if you have to do this more than in one operation.
I thought of saving all the evals in a var at start of the repeater?
DateTime mydt1 = Eval("myDate");
DateTime mydt2 = Eval("mydate");
after that, it's easy to do any operations in the whole repeater. Hope you understand my idea. Is this possible? I tried short but everytime errors.
mydt1 - mydt2....

to define a variable/property of more than one type. Let's say i want a property TextWebControl that is a WebControl and also implements Web.UI.ITextControl(f.e. like a TextBox or Label). But i don't want to enforce that it is a TextBox or Label, but only one that inherits from WebControl and also implements ITextControl so that it also would work with controls added in future releases of .Net-Framework.
.Net-Framework 4.0
Edit: I have retagged the question and added VB.Net because it's my default language. Normally it's no problem for me to understand C# also, but i must admit that it's difficult to translate generic stuff to VB.Net without experiences and it's also better documentated in C# than in VB. So i would appreciate(and aceept) a working example of a VB.net generic type of ITextControl/WebControl.
From Marc's answer i understand that i need a generic class. But how do i instantiate it in SomeClass? This won't compile:
Class SomeClass
Public Property info As InfoControl(Of WebControl, ITextControl)
End Class

first off I can't post the code, so I will do my best to try to explain what I am trying to do. I have a repeater with three literals (a member ID, a name, a uservalue) and three hyperlinks. Each of the hyperlinks goes to a different page (obviously).What I am trying to do is when the user clicks on one of the hyperlinks, (doesn't matter which one because the three literals need to be put into session variables regardless) I want the session variables set to the literal values before calling the next page.How do I get the session variables set when the user clicks on one of the hyperlinks?

trying to get something to work, which I think should be extremely easy.
I'm grabbing a value from my database with a repeater, and want to assign the value to a variable that I can parse and then send into javascript. 'videofile' is the variable from the database, and I want to assign the value to 'vidfile', parse it, and then inject into javascript:
<asp:Repeater ID="Repeater3" runat="server" DataSourceID="SqlDataSource11">

I query the database to get the VideoName and VideoURL of the videos held in my database (Videos saved on the file system with their location stored in the database) then bind the query results to a repeater with the following code
protected void Page_Load(object sender, EventArgs e)
{
// Variables declaration
string strConnString = ConfigurationManager.ConnectionStrings["vidConnectionString"].ConnectionString;
SqlConnection sqlConn = new SqlConnection(strConnString);
SqlCommand sqlcmd = new SqlCommand("SELECT [VideoName], [VideoURL] FROM [Video]");
SqlDataReader sqlReader;
sqlConn.Open();
sqlcmd.Connection = sqlConn;
sqlReader = sqlcmd.ExecuteReader();
VideoRepeater.DataSource = sqlReader;
VideoRepeater.DataBind();
sqlConn.Close();
}
and put a hyperlink into the repeater to list all the VideoName's this works fine but I want to pass the VideoURL to the next page I am using NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" but when I try and load the Page I get the error saying The server tag is not well formed. the whole repeater code is
<asp:Repeater ID="VideoRepeater" runat="server" >
<ItemTemplate>
<asp:HyperLink ID="VideoLink" NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" runat="server"><%# Eval("VideoName") %></asp:HyperLink>
</br>
</ItemTemplate>
</asp:Repeater>
I'm sure i've just got the hyperlink navigateURL wrong put not sure how else to pass the VideoURL variable

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?

I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
