I have a website developed in C# with Visual Studio 2010. I am using datalist to list the documents for monthly meetings. Each monthly meeting has 6 datalists representing each section of the monthly meeting. I am using row filters to filter the data for the respective month and section. I am using the Membership Provider model and am displaying the documents for the respective user. When a user clicks on the document link the document is marked and displayed as "read". This is all working as it should in my existing code.
However, I would like to be able to display this data programmatically. My oldest data is December 2009. I would like to dipslay this data programmatically based on todays's date and then looping back until December 2009. Today, I update the web form and the code behind on a monthly basis and I know that there is probably a better way to do this. I think this can be done but I am not certain if it can be done with row filters, because amongst other things I do not know how I can dynamically generate the datalist ids so that I can then bind the row filtered data.
Below is a sample of my code for one month of data.

I am trying to display a starting date from an access database based on the dateId field in a datalist.
On page 1 (using a master page) the customer selects a starting date from a dropdownlist. When the customer hits the submit button, they are transferred to page 2 where the selected starting date is displayed.
The database table is basically:
DateID Startingdate
1 1/1/2010
2 2/1/2010
3 3/1/2010
4 4/1/2010
5 5/1/2010
The dropdownlist from page 1 is:

I have a datalist with items for sale including an image for each item. I want to make another datalist with items that have been sold, but I want to display a part-transparent 'sold' sign across the corner of the image.
They only way I can think of is to display the item image as a background? With the sold image on top?
Any clue as to how to bring back an image from a database and display it as a background image? I haven't yet figured this out.
I've got a label in the item template tag of the datalist control. The label is bound to an integer column in the data source.
What I want to achieve is to retrieve the number from that label and change its text according to what number is retrieved.
i.e. if number retrieved = 1 then
lbl.text = "SomeText"
My problem is that I don't know how to code that label as it is found in the <ItemTemplate> of the datalist and intellisense cannot identify the label.
Is it possible for me to code that label using code behind? or is there any other way to do this?
I want to access my checkbox in code behind. I have my checkbox in my aspx file like this:
[Code]....
And i'm trying to set the checkbox visible=false like this but it's not working. Error message: Object reference not set to an instance of an object.
[Code]....
This is just one thing i want to do with my controls in my datalist, so i don't want to in my aspx file like this:
<asp:CheckBox ID="CheckBox1" runat="server" Visible='<%# if(Eval("isFolder")="1","false","true") %>' />
Because i have quite a lot of things i would like to do in the code behind when i'm getting my files..
Is it possible somehow to achieve this without having to put servercode in my aspx file?
I'm currently running with this.

Works find on initial page load, but gives me "Object variable or With block variable not set."
on this like "ColourHex = e.Item.DataItem("ColourHex")" on postback?
I have a DataList control setup with a Repeater inside it. It's displaying Ranks just fine, but the problem is I don't know how to make it start over with each DataList.
Right now, if there are two rows in the PointsCat table, it creates two DataLists (new DataList for each ID) and populates the Repeater with the person's rank, name and points from the Points table. The CatID in the Points table is a number equal to an ID in the PointsCat table (to tell which DataList's Repeater to display the data in). This code currently just orders ALL the entries from my database table, so the first Repeater in the first DataList may end with a ranking of 4 (4th), the first item in the next DataList's Repeater starts with a rank of 5...instead of starting over with 1.
So my current page may show something like this (notice the rank didn't start over in the second category):
Points Category 1 Points Category 2
1 John Doe 400 4 Janet Doe 275
2 John Smith 390 5 Johnny Smith 270
3 Jane Smith 380
My SqlDataAdapter line is below. I need it to start over the ranking for each CatID. Is it possible to do that within this line?

I have data in mydatabase. My AnswerText in the database is test1,test2,test3 While retrieving it is displaying as test3,test1,test2. I am using the below code to display the data.
Dictionary<string, string> dicKeyValues = new Dictionary<string, string>();
for (int i = 0; i < cnstsData.Answer.Count; i++)
{
dicKeyValues.Add(AnswerText, AnswerImage);
}
DataList.DataSource = dicKeyValues;
DataList.DataBind();
I want to display the AnswetText as test1,test2,test3. Basically i want the same order which i added to the database while retrieving also.
I am using a datalist to display data from a database.Except for 1 column all the other column values are getting repeated so I am hiding all the other column values when the datalist repeats itself.However, the unique column value is not getting rendered properly because there are many line breaks in between.I am not using any web control to display the static text and I am not sure if that would help.I just want to improve the final display so that the datalist looks consistent.I am attaching my code.

I have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example
Todays date (02/25/2010)
50 postings
yesterdays date (02/24/2010)
if 75 postings are there,
50 postings
it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this
yesterdays date (02/24/2010)
remaining 25 postings
(02/23/2010)
75 postings
how can i do the paging like this?
The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'.
In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I tried
<%# DataBinder.Eval(Container.DataItem, "_comments_Replies.childcomment")
Same as above error came to me.
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.
