View 1 Repliesi have a DAL function to get the records from DB. it will return a dataset. now i want to use linq from dataset and bind the dropdownlist, gridview data comtrols. pls any one give me a sample. also i want to know whether we can use distinct, fileter in linq.
View 4 RepliesI 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'.
i my website i am using Repeater control which further contain checkboxlist control. Now my problem is that i have successfully bind "Parameter Type" in repeater control but when i am binding checkbox values, it does't appears in display
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<h4>
<%#Container.DataItem%></h4>
<asp:CheckBoxList ID="chkParList" runat="server" RepeatDirection="Horizontal"
DataTextField = >
</asp:CheckBoxList>
<br /><br />
</ItemTemplate>
<SeparatorTemplate>
<hr />
</SeparatorTemplate>
</asp:Repeater>
In *.cs file following are my code
IMonitoringDataInfo objMonitoringDataInfo = new ChannelFactory<IMonitoringDataInfo>("MonitoringDataInfo").CreateChannel();
Collection<ParameterDetailDTO> clParameterDetailDTO = objMonitoringDataInfo.GetAllParameters(idList, out errorCode);
var parameters = (from resx in clParameterDetailDTO
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";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataBind();
}
i++;
}
I am using LINQ as datasource.
I have connected listview by using datasourceid that means by using "sqldatasource1" now i want to change value of listview at run time according to search so for that i am using datasource at codebehind. but it give an errorÂ
"listview have already bind with datasourceid you can not bind it with datasource"
what should i do for solving my requirement.
I am writing a plugin to help with a current ERP system we have that I am not allowed to modify the data structure at all. The table I am dealing with has over 100 columns and I am wanting to set my linq object propertychanged event and submitchanges or do I really have list out each property and set it equal to the new one?Below is an example of what I am trying to do:
[Code]....
txtLastName.Text = db.usp_ATI_FetchPatientDetails(iPatientID).ElementAt(0).Last_Name.ToString();
Like that I have large number of controls on my form. I have dought, if I assigned like this, db.usp_ATI_FetchPatientDetails(iPatientID).ElementAt(0).Last_Name.ToString(); to every control, then I have set of controls like,

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?
Executed a linq query, and now needs to bind it to the gridview. here is code that doesn't bind anything currently:
[Code]....
on my WebApplication I have GridViews filled with a LinQ-Query. Like this
Dim teamA = (From t
In datacontext10.T_TEAM
Where t.group =
"A"
Order
By t.sort)
GridViewA.DataSource = teamA
GridViewA.DataBind()
Now I want do enable automated Sorting and Paging? How could that work? Could I use a ObjectDataSource? Which control could do that for me?
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 !
im explaining this base on a test page that i have hosted as i was trying to track down my problem, i have a hosted page which i have hosted on the internet on a hosting service provider. the page has a normal gridview that is linked to a SqlDataSource. and theSqlDataSource has sql statements for selecting data, updating and deleting. They all work fine locally and even if i host them locally through IIS. but on the hosting service they down work. only the select work, which means i can view my data on the gridview but i cant manipulate it, delete and updating dont wanna work, they dont do anything. and the worse part is that im not even getting an error from them, on the grid i have enabled the autogenerate edit button and the delete, how can i make the update and delete work, or what is it that makes them not to work. the code for my test page is below

I have got an issue while using LINQ 2 SQL.
public IEnumerable<Customer> GetCustomers()
{
Table<Customer> custObject = context.Customers;
IEnumerable<Customer> filteredCustList = from customer in custObject
select customer;
filteredCustList;
}
GridView2.DataSource = utilLinqClass.GetCustomers();
GridView2.DataBind();
(no errors at build time or at compile time) Error I am getting is: An attempt to attach an auto-named database for file App_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
I've created a query in the table adapter for retrieving customer name based on the first letter. The query is executed fine, and the output is the customer name and ID. A Customer BLL accesses this query, and sends the results to an objectdatasource. This control is configured to use this customer-by-letter query. However for some reason, this objectdatasource does not bind the name and ID, but instead all the other fields produced by the main query in the table adapter (i.e. name, address, phone, etc....).
I'm probably not configuring something correctly, but I'm not sure what.
The BLL code:

The .net code:

Is it possible for me to have an ObjectDataSource and the bind a texbox to a certain field to it?

View 1 RepliesI have a listbox controll and i want to bind it with an SqlDataSource.SqlDataSource must be declared in the code behind but i don't know where declare it(page init,page load...)and how to add sql parameter dynamically (parameters are the selected values of listbox, so they are multiple).
View 2 RepliesI have a list that I need to bind to a List I get from an API. The list looks like this:
struct DataItem { int level; string name; Guid key };
List<DataItem> myList = API.GetList();
ListView1.DataSource = myList;
ListView1.DataBind();
All this works fine for display. However, the table must edit the level value. I am unsure how to make that happen. I have tried event handlers on the listView, but they are never called. I have tried a text box for the level field (with both Bind and Eval) and an event handler OnTextChanged, but the event handler is never called. (I have tried with various combiniations of AutoPostBack and ViewState enabled.)

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
I have this list of names where I want the location underneath each name but nothing is showing up. Is it not actually possible to bind the repeater's datasource to the items in the datalist because nothing is really selected in the datalist - it's just all there?
