Forms Data Controls :: Showing Linq Result Values Inside Dropdownlist Inside Listview
Jun 22, 2010
I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
[Code]....

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

I am loading the autocomplete extender properly but I need the PK from the selectedValue. I have looked at other examples and they do NOT show how to drill into the tabcontainer, then drill into the listview, and then locate the extender value. Here is what I have so far. My "TABCONTAINER" value shows the extender correctly but I am unable to locate it.

I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see:
http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate
It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
See below:

I have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.

I'm trying to do a validation for checkboxlist on a server side as all java approaches didn't work. However, probably due to the checklistbox is inside a listview the FindControl is empty. how to find a control inside a listview on a button click event when the button is outside of the listview.
<asp:CustomValidator
ID="rfchblAnswers"
runat="server"
ErrorMessage="* Please, select at least a one checkbox."
OnServerValidate="cblCustomValidator"
EnableClientScript="false"
ValidationGroup="EnterData"
Display=
"Dynamic" />
Public
Sub cblCustomValidator(ByVal objSource
As Object,
ByVal objArgs As ServerValidateEventArgs)
Dim chblAnswers As CheckBoxList = _
CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
If CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
IsNot Nothing
Then 'it's not working here as it cannot find the control inside a listview
Dim boolFlag As
Boolean = False
For Each li
As ListItem In chblAnswers.Items
If li.Selected Then
boolFlag = True
End If
Next
If boolFlag Then
objArgs.IsValid = True
Else
objArgs.IsValid = False
End If

I have a listview and inside the listview I have a gridview. I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button. I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works. But if I rebind this gridview, nothing happens.
I can trace through the rowediting and everything is working. It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening? Why isn't my rebound edit mode gridview showing up?

I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.
A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing
A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)

I have a ListView that uses an ObjectDataSource

When I move the DataPager OUTSIDE the ListView control and set its PagedControlID
to the ListView, it stops working and the ListView's PagePropertiesChanging event no longer fires.
i.e. This works (and the ListView's PagePropertiesChanging fires):
