My problem is that I have a different format table for each section in my form. And I would like to bind data to these tables. A repeater I don't think is going to work. It would be great if I can do it like this:
[Code]....
Where the "+ 1" is the next record from that datasource --which is bound in code behind. Is there anyway, I can accomplish this without resorting to dynamically created tables.
I'm trying to implement an ASP.NET DataBoundControl that supports two-way databinding. Unfortunatelly I can't find any documentation on how to do this on the web and even Dino Esposito in his ASP.NET 2.0 Advanced Topics only handles one-way databinding (also the contact form on his blog isn't working). Can anyone provide me with documentation or samples on how to do this?
View 2 Replies I have a gridview which I have databinded via the quick config facility, but I need to databind one column to a completely different sql table data field - how do I do this?
If I go into Gridview tasks and select the column and edit the data binding parameter but what is the format for a table outside the source definition for the the rest of the gridview?
i created a chart in Excel, but now I am having the time of my life to create the same chart in a control.
If you can see on the bottom I have converted the labels to percentages.
In excel I am using a series of data cells to create the bottom labels (0-8 with a .5 increment).
The Y-axis is done with a fixed maximum value of 2 and the labels are percentages as well. How do I get those same axes on the chart control?
On one of my webpage i am displaying datalist in which i am using this label:
<asp:Label ID="nameLabel12a" runat="server" Text='<%# Eval("CreatedOn") %>' />
This label is displaying created on date along with time (10/18/2010 2:45:07 PM), but i would like to display it something like this:
7sec ago
20min ago
30min ago
23 hours ago
10/3/2010 (if the time is more than 24 hours then it should display the date)
I'm currently developing a system for booking of discussion room in a college. This system will allow the staff to help the students to make booking in advanced as well as for instant walk in usage.I've got a table to keep track of bookings, another for walk in and one for time slot.
For the time slot table, it includes start time slot and end time slot, which is 30 minutes interval for each.What i'm currently facing is that the system could not display the correct available time slot. I think it's the formula problem which I still can't get it solved.
Example:If the booking time is 8.30am - 9.00am, I have no problem showing the 1st slot as N/A.
But if the time is 8.45am - 9.15am, the system only update the 1st slot as N/A while the 2nd slot still remain as AVAILABLE which is wrong. Because since the time ends at 9.15, I would like the slot 9.00am - 9.30am to be N/A as well.
This would be my code:
[Code]....
I have total 21 time slot count in my table. And the arrCC113Availability is an ArrayList keeping track of the availability of each slot for that particular room.Is there any other formula which can cater for all the conditions?

Here is the URL to the Screen shot [URL] I want to display the data in the format that is represented in the screenshot. All the data that is shown is retrieved from Sql Server-2005 Database. Which is the best option for such kind of data representation? I have read in the forums, from them I could not get a clear perspective. Some were suggesting listview others nested datagrid, some repeater control. which one would be a easier, proper and accurate way to go forward ?? Along with some reasons (if possible !!). And I'm using visual studio 2008, .net Framework 3.5, asp.net with c# and I'm NOT using LINQ in my project and it is a web application. URL Screen Shot: [URL]
View 2 RepliesI have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />

I'll use Customer and Addresses as an example rather than explain my real objects. Say I have a repeater bound to a collection of Customers and one of the properties of Customer is an array of addresses. How do I bind to the addresses property? I don't even need to display this information I just want to use it in the Repeaters ItemDataBound event. So I tried to bind a hiddenField to the addresses property but all I get for every customer in the hiddenfields value is an empty array of addresses.
View 1 RepliesI have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.
One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.

Inside my repeater I'm calling an extension method like so:

he above is giving me an "Object not set to an instance of a object" exception inside the extension method. If I comment the above expression out, it works fine, and the items are binded wtih no problems.
im trying to use dynamic object in a databinding tag , it gives me error that the property does not exists even though i can see all the properties there in the vs debug mode
here is what im trying to do:
C#:
my method signature:
public static dynamic MyMethod()
ASPX:
in control itemtemplate:
<%# MyMethod().SomeProperty %>
if also trite the other way:
C#:
public static object MyMethod()
ASPX:
<%# ((dymanic)MyMethod() ).SomeProperty%>
But i dont know why it cant resolve the properties , even though i can see them when the databinder control throws an exception (its working fine outside the databinder tag (ie normal aspx tags <% %>)

I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:
[Code]....
Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).
I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:
text='<%#Bind("Question") %>'
At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).

I was wondering what would be the best pratice to databind a gridview programmatically.Normally i put my databind code in the page_load() but is there a way to reduce the number of times the databind method is called?I mean... the page_load() method seem to be called a lots of times when doing callbacks with the grid.
