Web Forms :: Nested Dropdownlist Ondatabound => Bind Other Dropdownlist Fail
Dec 9, 2010
I 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
How to bind "OnDataBound" event of "DropDownList" in declarative syntax to a static method in some other class ?e.g<asp:DropDownList runat="server" id="d1" OnDataBound="SomeOtherClassThanThisPage.StaticMethod"></asp:DropDownList>

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:

I have a webUserControl that is nested inside of another dynamically loaded usercontrol. The nested user control (harddrive) can have multiple iterations, see below for hierarchy When a postback occurs the value in the dropdownlist inside of the nested userControl is saved, but the data in the textboxes is lost. any ideas?
Hierarchy: insert.aspx [^--loads] asset.ascx [^--- loads] harddrive.ascx -- there can be multiple instances of this control inside of the asset.ascx user control
I want to bind data(For ex: Employee name, Employee ID from Employee) to a dropdownlist and the data should be displayed in dropdownlist as two columns. I don't want to separate this columns by using any special characters like | or '-'. I want to display them as different columns in a dropdownlist.
How can i achieve this using .net and the data i need to retrieve using SQL server 2008.
I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
I am having trouble populating two dropdownlist controls with a list of files.The controls should be loaded with a list of images and paths that are held in the IDictionary object.The dropdown controls are nested in a Formview Control under the currentmode of insert or edit.Here's a clip of my form code:
I have a dropdownlist in datalist. I use arraylist to bind the datalist. In arraylist it is "DataNew" Class which has the property of DataTable "dt_city". Now I bind the DataTable to dropdownlist
Line73: <tr> Line 74: <td style="width: 100px; height: 24px"> Line 75: <asp:DropDownList ID="DropDownList1" runat="server" Line 76: SelectedValue='<%# DataBinder.Eval(((DataNew)Container.DataItem).dt_city,"city") %>'> Line 77: </asp:DropDownList></td>
But I got the error of: Server Error in '/AFIRS' Application. DataBinding: 'System.Data.DataTable' does not contain a property with the name 'city'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I'm trying to bind a dataset (where the data is coming from a webservice) to a dropdownlist; the problem is that I'm getting duplicates in the list... how can I display distinct values only:
I've got a Dictionary<string, string> object I'm creating:-
