Sharing Value From Child To Parent Control?
Oct 11, 2010
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.

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).

If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.

i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

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.

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?

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."

<?xml version="1.0" encoding="iso-8859-1" ?>
- <newdataset xml="version="1.0" encoding="iso-8859-1"">
- <officelist>
<officeid>2</officeid>

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

As you can see above, my table structure follows this pattern
[Code]....
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.
