Since a Visual Basic client doesn't handle events directly from late-bound COM objects, it needs some way to capture all the events and parameters launched by any COM object server instantiated at runtime and not known at design time. This article explains how to build a bridge component that does just that. The bridge component transmits the intercepted event data back to the Visual Basic client using another supporting COM object that is capable of holding event data and attributes. The Visual Basic client receives the notification from the bridge and extracts all the information relative to the event from the supporting object.

How can I get pass the DataKey of a GridView to a usercontol, preferably without code behind.

Why doesn't this work:

<ucOrderDetails:AJAX_OrderDetail ID="od1" runat="server" OrderNumber='<%# GridView1.SelectedValue.ToString() %>'  />

GridView1 is just a list of orders with a DataKey of OrderNumber.

od1 is not inside of a databout control, does it need to be?

Hi All ~~ I'm confused, Can i have some help please... Thanks

Database: Books

uid dataType uniqueidentifier

Cover dataType image 

aspx :

 <asp:FormView ID="FormView1" runat="server" BackColor="LightGoldenrodYellow"   BorderColor="Tan" BorderWidth="1px" CellPadding="2" DataKeyNames="uid"     DataSourceID="SqlDataSource1" ForeColor="Black" Width="525px">
     <EditItemTemplate>
         <table class="table_width">
             <tr>
                 <td class="imageWidth">
                     <asp:Image ID="Image1" runat="server" Height="245px" 
                                       ImageUrl='<%# IIF(Eval("Cover") Is DbNull.Value, "~/Styles/Global/CFZ-No-Images.png", Eval("uid", "~/ImageServices.ashx?BooksID={0}")) %>' Width="180px" />
          

I have a formview1 with a dropdownlist1 in the insert template. Based on the value of that dropdownlist I would like to display a second formview on the same page in insert mode so that I can write data to two different tables.

How can I accomplish this?

Is this the best way to do it?

thanks.

I have an "Edit Page" in my application. It uses a FormView bound to an EntityDataSource.

I have a handler setup for the FormView OnItemUpdated event. If an exception occurs (such as foreign key constraints or non date vales entered in a date colum, etc.), then I set the "KeepInEditMode=true". This is SUPPOSED to retain the user entered values on all of the text boxes instead of rebinding the FormView to the data again and clearing those text boxes. (Right?)

Well, it isn't working...

I have stepped through the code via the debugger and the "KeepInEditMode" does get set to true, but as soon as the page reloads, the values revert back to the original database values (the data is being rebound).

I should also mention that I am setting "ExceptionHandled" to true. I am doing this because I am handling the Exception by displaying an error in a specific area of the page and if I dont mark it as handled, IE generates an Exception popup.

Any ideas?
 

Hello, I have a FormView which is used to insert a record into a database.  Outside of this formview i have a drop down list, I want to grab the value from that drop down list and set one of the text fields within the formview to it's currently selected value.  I've tried the following code, but the dynamic categorytextbox line is what seems to not be working.

                    <asp:DropDownList ID="ddlCategory" runat="server" AutoPostBack="True" 
                        DataSourceID="SqlDataSourceCategory" DataTextField="CategoryName" 
                        DataValueField="CategoryID" Width="200px">
                    </asp:DropDownList>

                            <asp:TextBox ID="CategoryIDTextBox" runat="server" 
                                Text='<%# Bind("CategoryID") %>' Visible="False" />

        protected void FormView1_DataBound(object sender, EventArgs e)
        {
            dynamic varCategory = ddlCategory.SelectedValue;
            dynamic categoryTextBox = FormView1.FindControl("CategoryIDText

My SetUp (I am using EF for my data):

1 Grid bound to a collection of Vehicle Objects

1 Combobox with multiselect enabled bound to a list of VehicleExtras.

Each vehicle has a collection of extras. 

My Problem:

What I need to do is have the Grid filter Vehicles based on whether those vehicles have the selected VehicleExtras from the Combobox

Can anyone point me in the right direction as to how this filtering should be done (if it is at all possible!)

Regards,

Dave

Does anyone know if its possible to use a DropDownList within the PagerTemplate to navigate to a specific record?  I have been able to place the DropDownList outside of the FormView and PagerTemplate and make it work, however, I can't get it to work inside the PagerTemplate.

Thanks
