5 Cascading Dropdowns (Parent To Child And Child To Parent)?
Aug 26, 2010
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).

In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.

Is it possible to refresh parent page from child's child page using javascript.
I have a webform which opens a child window, a button on child window closes the present child window and opens a subchild window. Now a button on subchild should close the window and refresh the parent form.

I have a nested child and parent UpdatePanel. The problem is, when the child UpdatePanel is refreshed/posted, the UpdateProgress in parent fires up. How can I prevent this? The structure is like this:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">
<ContentTemplate>
<asp:UpdateProgress ID="UpdateProgress3" runat="server" AssociatedUpdatePanelID="UpdatePanel2">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</asp:UpdatePanel>
When UpdatePanel2 is posted, UpdateProgress3 is not displayed but UpdateProgress1 and UpdateProgress2 are. What should I do?

In asp.net, I have a parent and a child control. Within the child control I have a dropdown list. Based on dropdown list's selected value I would like to toggle Visibility of Panel in parent control. For instance if I select Show in child control dropdown list, I need to pass true to parent control to make Panel visible and vice versa. How should I do that. I have read that can be done via the event handling and have seen certain scenarios but I am not clear on that.

i am working on POCO entities. i had a requirement to provide Edit feature for parent and respective Child records in single View.
Eg: Parent-Customer, Child-Order tables
when updating the parent entity by using => UpdateModel(CustomerIns);
and updating the child entity by using => TryUpdateModel(CustomerIns.Order, "Orders");
The Child Controls Names are like Orders[0].OrderID,Oders[0].OrderDate,etc
The Parent and Child Entities are updating when UpdateModel() is called but when saving Changes by calling Context.SaveChanges() i am getting exception like:
"The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted."

I have an xml document that has a structure like so:
<?xml version="1.0" encoding="iso-8859-1" ?>
- <newdataset xml="version="1.0" encoding="iso-8859-1"">
- <officelist>
<officeid>2</officeid>
<office>Office</office>
<region>BC</region>
I would like to have the office id = 2 to be its own element. Like so
<?xml version="1.0" encoding="iso-8859-1" ?>
<newdataset xml="version="1.0" encoding="iso-8859-1"">
<officelist>
<officeid id=2/>
<office>Office</office>
<region>BC</region>
</officeid>
</officelist>
</newdataset>
xmlDS += offices.GetXml();
xmlDS = xmlDS.Replace(@"xml:space=""preserve""", " ");
XmlDocument doc = new XmlDocument();
XmlNode declaration = doc.CreateNode(XmlNodeType.XmlDeclaration, null, null);
doc.LoadXml(xmlDS);
doc.Save(Response.OutputStream);
That is my code so far... not sure how to set a child node to become a parent node

My overall aim is to have the sql order the table for me, and by using this new "depth" column, I will be able to indent by categories in the menu on the front end, you have probably seen this before, but all the tutorials I have read dont really explain it very well, or assume you are sql savvy.

I am developing a C# VS 2008 / SQL Server 2008 website. Although this same code compiles in the Project version, the website version does not compile. Many of their files are the same so I do not understand even where to look. The only compile error I get is:
Could not load type 'DataMatch'
in my DataMatch.aspx file. Is the problem in my web.config file? How do websites differ from projects in VS? All four of these files reside in same directory.
