Web Forms :: Formview - Insert Item Template - Fill Various Textfields According To Dropdown List
Mar 26, 2010I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

Nov 3, 2010I have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?

Web Forms :: Clicking The Label Of A Dropdown List - Resets The Selected Value To The First Item In The List?
Feb 17, 2010Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.

AJAX :: Autopostback On The Last List In A Cascading Dropdown List Series/ Invalid Postback Or Callback Argument
Aug 20, 2010I have a Cascading drop down list that is working fine to load the correct lists however I would like to have the last one initiate a query and display a datagrid on the same page containing the results of the query. Without Ajax involved this seems rather easy by using autopostback on the drop downs. If I could do it through Ajax that would be great but I can settle with having the page to reload to display the data. Right now I'm not sure how to do either. I enabled autopostback on the last drop down and wrote a method for it but I get an error at runtime saying:
Invalid postback or callback argument
Templates - Populate List Items In Dropdown List From Placeholder?
Feb 24, 2010I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
