Looping Through Parent Child Combination Xml Using C#?
Dec 7, 2010
I am new to xml, i want to looping through the below xml and save the records in the database. the below xml is parent child combination, parts as to be saved under respective parents. if the source field is M then there will be child item for that.
I have very strange Cascading Dropdownlist behavior. When I use one parent, one child - everything is fine, but one parent two children combination does not work well. Sometimes both children show right data; sometime first is fine and second is grey, or first is fine and second [Method error 500], or second is fine and first is wrong and so on.
Did somebody try to use parent two children combination?
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:
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."
When I open two modalpopups, one over another, there is unexpected order.After click on "Open Parent Panel", and click on "Open Child Panel",Child Panel (newone) is under the Parent.

I am building treeview using asp.net 2.0/3.5 from master detail table.
ParentTable Value ---ChildTable Value ---GrandChildTable1 Node ---GrandChildTable1 Value ---GrandChildTable2 Node ---GrandChildTable1 Value
I have created something like this to populate node values. But I am not sure how to display GrandChildNode and values. Could you please let me know if there are any ideas?
protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { switch (e.Node.Depth) { case 0: GetParentTableValues(e.Node); break; case 1: GetChildTableValues(e.Node); break; case 2: } }
I want to create a listing view in which the record will be in this format(basically one record based on other, what mvc approach i should follow) .Basically i am using linq to sql and i have module and features in the same table with module being identified by is module =true tag . basically i am looking for suitable mvc approach. i could create a codebehind html table and rendered it here but that not i am looking for.

I have a table that needs sorting by its hierarchial structure of parent-child.
An example of my table is below
ID Name Parent ID Sort Order 1 iPhone Dev 0 1 2 iPhone Lounge 0 2 3 Web Development 0 3 17 Javascript 3 1 24 CSS 3 2 25 prototypes 17 1
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.
how to insert parent/child data to the database. I have a form with two 'dropdown' lists and two text boxes and a 'Comment' text area. I need to save some fieldsto the Parent table and some fields into the child table.
how controls (txtbox, radio, etc) are mapped to properties in my Model. Now to the next part : My scenario (example):
Model: three tables: tblPerson, tblPersonOptions, tblOptionsConfig UI: Person Name: ______ (required) Person Age: ________ (required)
radio button: Does Person want to select options? Yes / No ? (required) If yes, then show a checkbox list of options from tblOptionsConfig: (required if yes above). Scenario I tested:
Person Name: Tester User Person Age: Left blank (check if validation error is thrown) Radion button: Yes. in options check ..let's say 3 out of 5 options. The UpdateModel throws the validation error and the page is returned back to the view(add.aspx).....................
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.
