View 5 Replies'm not sure if this is the right forum, but I couldnt find one for linq related questions.I have the following problem. I have four tables, One with users, one with projects, one with the users and the projects they are in (joinProjectTable) and on table where the users can fill in there worked hours for a certain project. These hours are filled in on a daily base. Now every month there is going to be created a report on the workedHours table so there is visible which user has entered how many hours for a certain project. On this report there is gonna be a billing for the company where for the hours are worked. This is the easy part, the hard part is the following.
companies also want to have a list of users that didn't entered any hours for that particular month for a particular project. So I have to write a linq query that would look in the joinprojecttable to see which users are joined to which projects, and than with that join it should look if that particular combination (user+project) is in anyway entered in the workedhourstable for that particular month. If not this has to be shown in the datagrid, for every user that isnt in the workedhourstable for that month. So it should be a certain NOT query, but I can't seem to figure it out.does anyone have any idea to accomplisch this in Linq2Sql? I'm using VB instead of C#.
I am VB.Net Windows Application Developer Now i am going an ASP.Net Application. So, the Problem is that in Windows Application i Code this Project like given Below Actually i am Using SQL Server as DataBase and Store Procedure as Query.Becuase i had tried to control the ASP.Net Data Grid with Loop and i Failed to Control it with this method
Private Sub btn_Ok_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles btn_Ok.Click
Fill_dataset("Sel_MovNames", "Tbl_MovNames", Convert.toint32(cmb_MovID.SelectedValue))

I am trying to find the best way to have a page with a lot of data from queries to a database load faster. Looking at [URL], when viewing information about a domain, I see that their page loads and each section has a loading symbol, so the page itself displays fast and the data comes when it is available. How do they do this? Update panels around each section with a call to a Web Service? Also, Google AdWords seems to do this too when you load the Ads or Keywords tabs of a Campaign.
View 3 RepliesI have an ASP.Net website, that uses a MySQL database. First of all, because the Connect/Net of MySQL doesn't install on PC (reason unknown, no error, it just doesn't work) I'm using ODBC for the connection. I've written some nice wrapper classes for using the database, and it's all working ok.
But now I'm adding a little Silverlight application to my website (first thing I'm making with WCF/Silverlight, without actually reading any tutorial, so let's hope for the best).
Now this application won't be anything fancy, it's only for the administrators, to read the logs, and change some configuration settings, etc, nothing fancy at all. But what it has to do is retrieve data from the services.
What I've done is a setup a service reference, and it works like a blessing, but now I'm trying to read the logs from the service, and I'm getting in trouble, because my class was never built to serialize to XML, first issue. And secondly I wouldn't know how to bind the retrieved data at the client to the datagrid.
I'm going to parse the recordset at the server so that I'll be sending a class containing an array of columns, and a multi-dimensional with the data to the client, now that's not much of a problem, I'm just mentioning it so that you can either improve or keep in mind what the data will look like.
My question: How would I bind that retrieved data to a plain <sdk:DataGrid>?
I have datagrid with paging enabled that can have 10 rows per page. Also I have DataTable with 16 rows. I want to fill the datagrid dynamically with 'for' loop to go over all the DataTable and fill the DataGrid.I understand that there is a problem when the counter will hit row 11. Do I need to change the page of the datagrid when counter will be 11? Because it doesnt let me add more than 10 rows in the datagrid.
View 1 RepliesI have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

But How can I do this?
I have tried the following, but that didn't do the job:
[Code]....
I have a Grid and it is filled with a list of objects... the problem is that in one column i want to show the name of one of his proporties... the problem is that this property is other object... I mean, my object medication has inside other object called producer.. so i want to show the name of this producer..
[Code]....
on the column Producer the thing that appears is : Entities.Producer.... but i want to show the name.. I tried with Producer.Name but in this way i have a error.
I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?

i am trying to fill agrid view with its data inside an accordion in asp.net but the data doesn't appear in the grid
View 1 RepliesI'm using VWD 2008 and using an SQL database with a simple web app.
I've created a SQL query that pulls data from several tables. When I execute the query in
the query builder tester, it executes OK. I'm binding the DetailsView to an ObjectSource / DataSet / TableAdapter Querry with a variable that is bound to a listbox control.
Again, the query runs fine in the query builder.
When the detailsview or gridview gets built on the page it only displays columns from one database yet it executes ok within the query builder.
I can see the generated code for the detailsview does not create fields for every field returned by the sql query ?
I have one more time a problem with a DetailsView..I would like to fill a TextBox (or Label) with a function in my DetailsView and on the Update getting value contained in this control.
It works fine when I don't use a personnal method like Bind("..") but if I try to use my function it throws an error
[Code]....
That's what I use for now and it works but I would like to fill TextBox2 with value returned by my function and update datas with this value.
Using C#, Visual Studio 2010
I have 8 drop downlists created in .aspx page.
I try to programmatically fill the 8 using a single datatable. Each dropdownlist has its own column in the datatable and is supposed to display only the column that corresponds to it. It does display the column it is supposed to however it also displays a number of empty slots equal to all the other columns combined.Here is the code can someone tell me why I get the empty slots?

I have a SQL query that returns about 5-10 records. For each one of these records I want to query another table using values in that row as parameters and create/populate a GridView. Can I create these GridViews and SQL connections programmatically in a for loop? I mean, I can't just plop ten GridViews and SQLConnections on my page at design time because I'm not certain how many rows will be returned in the first query. What should I do?
View 4 RepliesI have a textboxes which I need to have a value of zero unless it is changed by the person filling out the form. So I have done this: In the page load
[Code]....
which makes the textboxes zero when the page loads. The problem is that when the form is inserted to the database it is not populating the field with a changed amount, but making it zero. I need to somehow tell it to ignore the zero fill command from the pageload. I think I have to use OnTextChange but am not sure how. This is what I have tried
[Code]....
What to make the "" I think is the problem
