Web Forms :: Separating Pieces Of Data?
Jan 19, 2010
I am trying to comprehend what I need to accomplish but I'm even struggling with the logistics of a this task. Okay, so I am pulling in a field from a SQL table. An example string value would be "Text: 150". The string for this field will always start with "Text:". I need to take the value, strip the "Text:" off the value, then compare the number at the end to carry out further error checking. Hopefully that makes some sense. I've never tried to do anything like this so I don't even know if it is possible.

I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}
}.............................

We need to add 2 user controls to an aspx file, these 2 user controls have one telerik ajax manager each. but telerik only allows one ajax manager in a web page. I am getting exception while running the app.
Is there any way in aspx to seperate the user controls so that it will act as a seperate page?

I'm implementing n-tier structure in the current app I'm working on. Because DataBinding a list of my Objects to a Repeater was far too slow I need to databind a DataTable to the Repeater. Should I still DataBind to a Function (that returns a DataTable) in the BLL that calls a Function in the DAL that returns a DataTable?

I would like to outsource pieces of a new web application/site. I don't want one company working on the whole project because they can easily change a few things and sell the software to someone else. I will be using a freelenace website like elance or guru. A buddy of mine has given me this advice but he did not say how this can be done.

Is it possible to add a property to the existing asp:BoundField control without creating a brand new instance to which I'd have to declare <tst:BoundField></tst:BoundField>? If so, can someone provide an example?

This obviously isn't right but I think best describes what I'm trying to do:
SELECT ImagesLge.MainImages
FROM pieces
INNER JOIN ImagesLge
ON ImagesLge.ParentId = pieces.ID
"WHERE pieces.ID = MAX(pieces.ID)"

Stored procedure:
[Code]....
This code returns MdaID and StateID, I want to assign them in this manner:
MdaIDLabel.Text = MdaID and StateIDLabel.Text = StateID, but I am not sure how to separate the two values and then to assign them as I have indicated above. Since my function has a "void" return -
MdaIDLabel.Text = GetMdaState({0}, 64114);
StateIDLabel.Text = GetMdaState({1}, 64114); - will not satisfy the requirement.
I am working with VS 2008 VWD, .NET 3.5 SP1, C#, SQL Server 2008 Express

I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

I have a many to many table in my database called PeopleLanguage
PeopleId, pk and Languags pk each go to the own table People and Language
I know make a method call with my objectdatasource GetPeopleByLanguageId
This returns the languages that the selected person speaks and has a select
query also to lanaguageTable to get LanguageName.
I now print out the results in a datalist that is binding to LanguageName.
What i want to do is show the languages in a horizontal format with a comma after each one.
At the moment if there are 3 languages it shows each one on a seperate line / if I make it horizontal
layout I still dont get a comma. Perhaps I can use a repeater?

I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?

I've tried various ways to resolve this but can't. This error points at the

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?
