DataSource Controls :: How To Select Data With Linq And Bind To A DDL
Jan 5, 2010
I am trying to select data with Linq and bind to a DDL. The custid field allows duplicates in this table, but I only want unique values in the ddl. I tried the following code:
[Code]....
The use of "Select Customer.CustID", with or without the Distinct, causes this runtime error. CustID is a valid field in the table, and it shows up in intellinsense and compiles. If I just Select Customer, the error goes away, but Distinct doesn't know to look for distinct custid's.
DataBinding: 'System.String' does not contain a property with the name 'CustID'.

There may be a lot of data in the Blogs table. What if all I wanted was say BlogID, BlogTitle and BlogAuthor and nothing else, is there a way to do this in an effort to make the sql more efficent?
Along the same lines in my DataContext (.dbml) file I added some associations between some of my tables. This makes coding nice when I do a linq statement that will join those tables automatically for me but my concern is does it do that everytime, thus making all my linq quieries inefficient?

I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.
[Code]....
Can anyone offer any thoughts on how I should construct the query to perform this?

I am trying to create a multi column listbox by combining fields in Linq select statement, as Let Name = Last + First. The problem is how to pad the Last column with spaces as you would in SQL using REPLICATE so when I bind the listbox to the data, it looks like two columns.

select resx.ParameterType).Distinct();
Repeater1.DataSource = parameters.ToList();
Repeater1.DataBind();
counter = Repeater1.Items.Count;
while (i < counter - 1)
{
foreach (var parType in parameters)
{
var items = from resx in clParameterDetailDTO
where resx.ParameterType.ToLower().Contains(parType.ToLower())
select new { resx.ParameterName, resx.ParameterID };
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataSource = items;
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataTextField = "ParameterName";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataValueField = "ParameterID";

}
i++;
}
I am using LINQ as datasource.

I'm new to Linq. I have searched and searched the web for a soluion, and can't find anything. I have a Linq query and I want to insert a row ("Select User") to the top before I pass it to the drop down list. I've been trying to use the Union but to now avail (it keeps telling me that my object doesn't support the Union method). My code, prior to attempting to inser a row, is very simple.
public SelectList DropDown_Users()
{
var context = new VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
list = new SelectList(query.AsEnumerable(), "UserId", "LastName");
return list;
}
Now I try to insert a row and I found this on the internet and it seems to say that his solution will work. But it is filled with syntax errors. [URL]
I tried to implement it using the following code, but it doesn't compile.
public SelectList DropDown_Users()
{
SelectList list;
//get the original data
var context = new SQL2005633131VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
//create a dummy table with an empty row
var AllUsers = new List<AspnetUsers>();
var BlankUser = new AspnetUsers()
{UserId=System.Guid.Empty, LastName="Select One"};
AllUsers.Add(BlankUser);
//use Union to join the data - ERRORS HERE
var newTable = AllUsers.Union(query);
list = new SelectList(newTable.AsEnumerable(), "UserId", "LastName");
return list;
}

I have a gridview with linq and in the itemtemplate I have a column like this :
Bind("SUPERFICIE","{0:N00}")
If I display my gridview, I have this kind of value : 6'555
When I delete this row I have this error :
Failed to define one or more properties of type DS.MY_TABLE 6'555 is not a valid value for Decimal.
Apparently, when I use a format on bind, it change my values in my ds and I cannot delete my row!
I don't understand, because in my logic with the bind format I don't need to correct some formats for delete a row !

There are multiple child nodes coming from Database in Treeview. Also, there is a DataGridview.
I want that when I select/click any of the child node from TreeView, it should show the related data(of selected child node) in DataGridview from Database on "Page Load".
My current code is below, which only binds all the data in DataGridview and Treeview from Database:
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
BindGrid();
FillchildNode();

The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

protected void Button19_Click(object sender, EventArgs e)
{
SqlDataSource conn = new SqlDataSource();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Database2ConnectionString1"].ToString();
conn.SelectCommandType = SqlDataSourceCommandType.Text;
conn.SelectCommand = "SELECT FROM table1 (a, b)VALUES(@a,@b)";
conn.SelectParameters.Add("a",TextBox1.Text);
conn.SelectParameters.Add("b", TextBox2.Text);
int rowsAffected = 0;
try
{
rowsAffected = conn.Selectt();
}
catch (Exception)
{
Label1.Text = "Error";
}
finally {
conn = null;
}
if (rowsAffected != 0)
{
Label1.Text = "Data saved";
}
}
well it returns error no overloading method for select (P.S. same code work fine for insert)

Before i talk about my situation or problem let me tell you all that i'm new to ObjectDataSource, ListView.
i've following controls
Three LinkButtonOne ObjectDataSource Control (which is binded to custom Business object) . Paging is enabledListView (This is binded with ObjectDataSource Control)
Requirements:
By default ObjectDataSource should be bounded to DataSource A, thus the user should see on page load the default data from DataSource A.When user Clicks on respective LinkButton, the ObjectDataSource should now be binded to new DataSource B, thus the user should now see data in ListView from DataSource B. The same should happen with LinkButton C respecctively
