Web Forms :: Nested Dropdownlist Ondatabound => Bind Other Dropdownlist Fail
Dec 9, 2010I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist
C# - Bind SelectedValue Of DropDownList To Nested Property?
Feb 10, 2010I have a asp.net FormView with a DropDownList for the selection of a month. The FormView is data bound to an ObjectDataSource.
<asp:DropDownList ID="MonthsList" DataSourceID="MonthsListDataSource" DataTextField="Value" DataValueField="Key" SelectedValue='<%# Bind("OrderDate.Month") %>' Width="100" runat="server" />
I like to bind the selected value to the nested property 'Month' of 'OrderDate' as shown above. The property OrderDate is of type DateTime. The error I'm getting while binding to a nested property is:
A call to Bind was not well formatted. Please refer to documentation for the correct parameters to Bind.
Forms Data Controls :: Bind Gridview Column To Nested Object?
Aug 2, 2010If I have a list of contacts List<Contact> and a Contact object has an Office object property, I want to display a grid with columns
Contact Id, First Name, Last Name, Office Name
Where the sources of the above columns are respectively:
Contact.ContactId, Contact.FirstName, Contact.LastName, Contact.Office.OfficeName
I'm fine with binding the first 3, but was wondering whether I can bind the OfficeName using either Bind or Eval or whether I need to hook into the events and set the value there.

Forms Data Controls :: How To Add Lookup Table Values To A DropDownList And Bind To A FKValue In The Grid
Jan 26, 2011I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB

Forms Data Controls :: Nested DDL From Second Table In GridView - SQL To Codebehind
Mar 8, 2011First, what I am showing here works fine, and I know how to do this if the nested control comes from the same bound table. I could leave it at that, but I don't like SQL code in my aspx page, and want to move it. I'm keeping it simple here, but I can move it to a data access layer later on..... for now, I want to understand what's going on when the page loads and the nested control is rendered and populated. WHAT I LEARN FROM THIS WILL BENEFIT ME ACROSS THE BOARD - NOT just for this instance!!!
My question is, how to grab the SQL query from the aspx page for the NESTED control and move it to the codebehind. I'd LOVE to also move the Selected Value parameter if possible, but mainly want to get the SQL out of the page. I KNOW HOW TO DO THIS for a GridView or any control, but I DO NOT know how to do it for a NESTED CONTROL from a different table - i.e. WHERE it fires (on GridViewEditing or GridViewUpdating or PageLoad....) so I can put in the SQL where it belongs.... and I'm PRETTY darn SURE this can be done without a 'foreach' loop. For discussion's sake here, imagine
1. DATABASE: simple table with employee_ID, employee_name, employee_city as fields
2. DATABASE: simple table containing all cities (city, cityval)
2. simple GridView that displays these 3 fields in same order ON VIEW
3. Template field for city. On PAGE LOAD, this is a simple label bound to the 'city' field. HOWEVER - On EDIT (with edit button), the field changes to a nested DropDownList that is bound to the 'city' table, NOT to the employee table.
4. Selected value is the current city for employee The PROC you see here in the edit item SQL is actually SELECT * FROM [cities] ORDER BY [city_name]
<asp:GridView ID="grdEmployee" runat="server" AutoGenerateColumns="False"
CssClass="grdE" DataKeyNames="employee_ID"
ShowFooter="True">
<Columns>
<asp:BoundField DataField="employee_ID" HeaderText="ID" ReadOnly="True" />
<asp:TemplateField HeaderText="Employee Name">
<ItemTemplate>
<asp:Label ID="lblEmployeeName" runat="server" Text='<%#Eval("employee_name")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtEmployeeName" runat="server" Text='<%#Eval("employee_name")%>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="City">
<EditItemTemplate>
<asp:DropDownList ID="cboCity" runat="server"
DataSourceID="SqlDataSource1" DataTextField="city" DataValueField="cityval"
SelectedValue='<%# Bind("employee_city") %>'>
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="Data Source=XXXXXXXXXXXX;Initial Catalog=xxxxxxx;Integrated Security=True"
ProviderName="System.Data.SqlClient"
SelectCommand="QUERY_CITY" SelectCommandType="StoredProcedure"></asp:SqlDataSource>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblEmployeeCity" runat="server" Text='<%# Bind("employee_city") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
ALL I want to do is move the SQL Query in the EDIT template above to the code behind. I just don't know WHERE or WHEN in the code this fires and how to handle it when the table is different from the original GridView table. AND the cboCity.SelectedValue, if possible.

View 1 RepliesBind DropDownList With Hierarchy From SQL Server Table?
Apr 27, 2010I have the following sql table which contains menu (website menu) data.
Table Name: MenuItems Columns: Id, MenuId, ParentMenuItemId, Text.
My goal is to bind a DDL according to the following hierarchy (example):
Id: 1, MenuId: 1, ParentMenuItemId: -1, Text: 'One'
Id: 2, MenuId: 1, ParentMenuItemId: 1, Text: 'Two'
Id: 3, MenuId: 1, ParentMenuItemId: 1, Text: 'Three'
Id: 4, MenuId: 1, ParentMenuItemId: 2, Text: 'Four'
Id: 5, MenuId: 1, ParentMenuItemId: 4, Text: 'Five'
Requested result in DDL:
One
-- Two
---- Four
------ Five
-- Three
I think it should contain 'WITH' SQL command.
Note: I'm using C#.

No you cannot add a third parameter in the Dictionary. It contain Key Value pair data.But if you want to add third parameter then simply use DataTable and add these in the DataTable row.Name of Builder , Title Of Buidler , Builder ID
So how to acheive that task ? so far i did like this :
public void AddNewCMP(string PersonName , string PersonID , string PersonTitle) {
var dt = new DataTable();
if (ViewState["CMPDataTable"] != null) {
dt = (DataTable)ViewState["CMPDataTable"];
[Code] ....
Now on button click i want to add six drop down values to AddNewRow(value1,value2,value3) method .... how to do that ?

How To Bind The Data Inside This Table To A GridView And DataList
Mar 17, 2010I am using an MS SQL Database with a table that has a DateTime column stored in it.
When I try to bind the data inside this table to a GridView and/or DataList the date shows up as (for example) '2010-03-03T00:00:00+01:00'.
In my GridView I tried to format that datetime by using the following 'BoundField' tag;
<asp:BoundField DataField="NewsDateEntered" HeaderText="Date Entered" DataFormatString = "{0:dd/MM/yyyy}" HtmlEncode="False" />
This is still wielding no results and I have tried to recreate the table and so on.

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?
Nov 19, 2010I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ).

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
