Simply I have 2 related tables Orders and Customers when I am editing an order I want to display the Customer in a Combobox. Let's say I wish to change the customer using a cbo The Customer Combo box should be populated with all Customers from the customer table the currently selected customer should be the current customer in the Order Table  for the Order I am Viewing The display member should be the customers name the tables are related with a CustomerID field in each table The data is EDMX   I have done some work on databinding in WPF and I can get combo boxes populated with Data but it's just not quite there. I can't seem to get the selected cbo customer to update to the Orders

Need to remove databinding of DropdownList when another dropdown list changes

  

I have many controls on my form, but in particular, I have 2 dropdownlists.  1 dropdown list has 2 values, and each value controls what the second dropdownlist displays.  This is an edititemtemplate and both dropdowns have the selecteditem set via '<%# Bind("fieldname") #>' on page load.  

THe problem is, if I change the value of the first dropdown, it errors out because the second dropdwon has a bound value that is no longer acceptable. 

Can I cancel the bind of the second control, if the the first one is changed?  I would like to cancel the bind, and update the values by using a different datasource depending on the value of the first dropdown or hardcode the new values.

 

Currently.

If Dropdown1 has a value of "A" for example Dropdown 2 Shows Values "1", "2", "3"

If Dropdown 1 has a value of "B" , Dropdown2 Shows Values "4", "5", "6".

It binds fine initially, but if I change Dropdown1 from A to B, I want Dropdown2 to show the new values, maybe with a default of "Select an Item" and not error out b/c it's attempts to bind a value of 1, 2, or 3.

 

Hope this makes sence, b/c I'm

Adjacent combo boxes take space according to their data on google chrome

  
I have a page where I want to keep several combo boxes adjacent to each other. I have put them in divs that are floated left.This works fine in IE, Firefox. But when I render the same page on Chrome I observe the uneven gap between combo boxes. Upon analysis I found out that each combo box is occupying space based on the data inside it.This happens because on Safari and Chrome, the option list control is placed differently as compared to that on IE and Firefox.Please see the following code from ComboBox.pre.js (in AjaxControlToolkit source/Server/) // force inline display on Safari by moving the list to the bottom of the form. if (Sys.Browser.agent === Sys.Browser.Safari || Sys.Browser.agent === Sys.Browser.WebKit) { this.get_element().removeChild(optionListControl); var parent = this.get_element().parentNode; while (typeof (parent) != typeof (document.forms[0])) { parent = parent.parentNode } var safariListContainer = document.createElement('div'); safariListContainer.className = this.get_element().className; safariListContainer.appendChild(optionListControl); parent.appendChild(safariListContainer); } This is how it looks:I have tried doing the following but none of them helped:Changed the RenderMode of combo box to 'block' fro

XNA and WPF, Databinding to a structs field such as Vector3 X Y Z

  
Hello people. Gonna go straight to the problem. I'm building a propertygrid with Datatemplates to define how each c# objects is gonna be shown on the UI. For example bools are drawn as checkboxes and strings are drawn as textboxes. A scenario where I'm having problems is with a class I've written called Transform. It contains the XNA struct Vector3 for position, scale etc. Xna Vector3 class members: http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.vector3_members.aspx Quick example of the content in the Transform class: private Vector3 position; public Vector3 Position {     get { return position; }     set { position = value; } } I want the Vector3 struct to be drawn as 3 textboxes for each element X Y Z. But I can't databind directly to the X Y Z elements because the struct doesn't contain properties, the X Y Z elements are fields instead, and databinding can only occur through properties. A workaround I did was adding 3 new public properties for each element X Y Z in the Transform class. Example of X element only: public float WPFPositionX {     get { return position.X; }     set { position.X = value;} } This allows me to bind directly to the elements of the struct because it's a property and it works! But now there&nb

Accordian DataBinding problem

  
Hi Folks, I am having a strange problem with an Accordian control which is databound to a DataView. Each pane displays data about a person. The problem is that when a new person is added which sorts to one of the inner panes, it initially displays the content (but not the header) of the pane following. For example, if there are two panes, one for Andy and one for Mary, and I add a new person named Bill, then the headers will be Andy, Bill and Mary, as expected. But expanding Bill will show the info for Mary. Both Andy and Mary display the correct data.  If I leave the page and return, all displays correctly. I have stepped through the code, listed below,  and verified to my satisfaction that when I rebind the control, the data in the underlying datatable and dataview is correct. Any thoughts? Thanks. Dan   Here is the declaration of the Accordian control:  <cc1:Accordion ID="accPeople" runat="server"   Width="400px" Height="100" TransitionDuration="1" AutoSize="None"   RequireOpenedPane="false"  SelectedIndex="-1" ContentCssClass="AccCntnt" HeaderCssClass="AccHdr"   HeaderSelectedCssClass="AccHdrSlctd">  <HeaderTemplate>    <table >      <tr>

databinding combobox which is inside a datagridtemplatecolumn

  
My datagrid is bound to a datacontext and I have a combobox inside a template column which has to be bound to a data source out of the existing datacontext.  I couldnt access that combobox from code behind. How can I achieve this. Also may i have a good learning resources for styling datagrid. Thanks :)   EDIT: I have two datatables in a dataset and my need is to intermix the data from both. Initially i set the data context to dataset.table1. Now I wanted to get values from other. So I tried the code-behind and found that I cant access elements in the datatemplate.   EDIT 2: I tried something like this: From code-behind: set Me.DataContext=mydataset And in XAML: when I wanted the values from 1st datatable: set the binding to table1/field. But I could see oly the first row of the datatable.
