How I can bind texbox to one property from linqdatasource?
I mean something like databinding contols in c# app
i have a grdidview control on the .aspx page and i am trying to connect dynamically from code behind and bind the gridview but somehow it throwing me an error... what is wrong with this code?
LinqDataSource LDS_POReport = new LinqDataSource();
LDS_POReport.ContextTypeName = "DataContextDataContext";
LDS_POReport.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDataSourcePO_Selecting);
this.gvReport.DataSource = "LDS_POReport";
//this.gvReport.DataBind();
Update:
after i update the code to this.gvReport.DataSource = LDS_POReport;
it works fine but when i try to sort i get this error:
The GridView 'gvReport' fired event Sorting which wasn't handled.
i added this but no effect.
LDS_POReport.AutoPage = true;
LDS_POReport.AutoSort = true;
the problem is not solved the way i wanted but i go ahead give the credit to : ĆukaszW.pl for his time and effort.
i am using gridview control and a linqdatasource and its all working fine and i have added the functionlity of searchingBySubject and i added WhereParameters and than binding my gridview (see the code below) but somehow its not returning any rows and i see i have number of rows based on what i am searching.
protected void btnSearch_Click(object sender, EventArgs e)
{
this.LinqDataSource1.WhereParameters["Subject"].DefaultValue = this.txtSubject.Text;

If I am going to use the asp.net membership and roles, the asp.net database includes an aspnet_Users table that has the userid and email address. If I have custom fields is it best practice to maintain a separate usert table and link on user id or to add fields to the aspnet_Users table?
View 1 Repliesin other words, reading the content (records that lies within) of a LinqDataSource object programatically (i.e. similar to what the GridView class does internally when binding to a LinqDataSource object).
View 4 RepliesI have set up Linq to sql. I now need to fill a formview with a select that does a join across a few tables. Have not been able to find any example or tuts that go beyond the simple select. Any suggestions? Can this even be done?
View 1 RepliesI am retrieving a column from a table using an SqlDataSource in ASP.NET/C#, which contains multiple 'values' separated by commas. I'd like to be able to separate this values into multiple columns in my GridView, and also allow them to update them. Is this easy to accomplish?
View 1 RepliesI have multiple tables that are all linked back to a central table with foreign keys. I want to be able to create a new record in table 2, but I'm having trouble because I don't know how to create a new instance of table 2's record while referencing the ID of the record it will be tied to.
EXAMPLE:
Database: Collection
Table: Collection Field 1: id Field 2: name
Table: Book Field 1: collectionId Field 2: id Field 3: name
Now, I don't want to be able to create a book without setting it's collectionID, but I can't figure out how this should be divided in the controllers/views.
Should Book have a controller separate from Collection, or should the Collection controller have a createBook method, separate from it's own create method?
I want to call the createBook method (from it's own controller, or the Collection controller) from the Collection Details view.
When I invoke the create method of Book, how do I create a new Book that is instantiated with the collectionId set from the details view of the Collection item that was listed in the details view?
I should point out, I'm using the entity framework for my model, and I'm definitely new to this.
I am modified CreateUserWizard Template to accept additional user information such as address, city, state and zip. I wanna store this additional data into a table i create call UserInformation.

I have an event that is called after a new User is Created and it is at this point where i wanna write the Address, City, State and Zip to the the database. What is the best way to write the data to the database..

I am working on a multi-lingual application Assume the following:
Database has 50 tables and application has to support 5 languages
Which is the best way to design the database:
1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)
2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.
Which is more efficient out of the above two.
I have made a call logging application in which i have authorised a normal user to edit update and delete from the gridview.But i want to give the admin person rights to see all the complaints deleted updated edited..i have thought a lot but all in vain havent found.
View 1 RepliesI have access to two seperate databases (mySQL) located on two servers. I need to get the data, link the tables on a key field and display the results in a datagrid. My challenge is that if the search criteria changes for the display it affects rows returned from on table and should thus automatically affect the linked table and resulting data returned.
what the best approach would be to achieving this? So far I have set up a dataset with a dataadapter and table for each connection and then linked the tables in the dataset. The problem that I'm having is getting the linked resultsets to work.
On my form I have the datagrid with two Objectdatasources one for each dataadapter and i believe that's where I'm going wrong...
I have a table named RECIPE which is linked to an other table name RECIPE_STATUS
In RECIPE table I have a field named Status_Id which contains the name of the Status which is fetch from the RECIPE_STATUS table based on this ID.
The RECIPE table sample information are as follow :
ID Name Status_Id
====================
1 Test1 0
2 Test2 1
3 Test3 2
The RECIPE_STATUS entries are as follow:
ID Name
========
0 Locked
1 Running
2 Free
From an ASP.net page I would like that my user is capable of changing the RECIPE_STATUS from a given recipe. For that I have a DataGrid which is bind to the RECIPE table.
But then what I would like is that the STATUS shown to my user to be the name Locked,Running or free depedning on the Id
How can I bound in my Datagrid the Recipe.Status to be bind to RECIPE_STATUS.Id ?
IN addition to that, If my user change the status for a given recipe, it should be properly save.
I'm making a simple homes classifieds section and when a home ad is created, a HomeID is automatically created for it in the db. I need the images to upload and enter the associated HomeID with each image automatically. What I tried isn't working, because it looks like it's looking for the HomeID in the codebehind before it gets entered into the db.
ASPX CODE
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
InsertCommand="INSERT INTO [Homes] ([UserName], [Street], [Details], [Contact], [Phone], [Email], [Thumb], [Price], [Approved], [Posted]) VALUES (@UserName, @Street, @Details, @Contact, @Phone, @Email, @Thumb, @Price, @Approved, @Posted)"

I think I may have done this wrong. I have a form with radio buttons and checkboxes. Each one of the checkboxes values are in a separate row in the table. How do I bind the values of the checkboxes to the controls. I cannot do a for each because that would repeat the HTML in the view around the checkboxes.

I don't think there's an easy way but thought I would ask. I'm currently retrieving a table from my db and binding it to a datagrid with the AutoGenerateColumns on. One of the columns is a date and it's displaying time although it's always 12:00:00. I'd like to display the short date format in the datagrid. Is there an easy way or do I have to manipulate each row or bind the columns individually?
View 1 RepliesCurrently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back. In my example, I have a Class called "Ingredient" which has 4 public accessories: Name, Barcode, Amount, and Unit.

VS2010/C#. I have a gridview bound to a SQL Server table with the default SELECT statement returning only a few rows. This is straight out of the box, so no need to show markup.
Upon a button click event I update the datasource: SqlDataSource1.SelectCommand = hdnSQL.Value; Then bind: qlDataSource1.DataBind();
But when I run this, I get this error:
System.Data.SqlClient.SqlException was unhandled by user code. Message=Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I am clueless. I have done this many times in the past and NEVER encountered a timeout.
I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

When I select a value in Combo box automatically that value is also getting selected in List Box and same thing when I select a value in List Box that value is also getting selected in Combo Box.
Selection should be only for that particular control, how can I achieve this ?
