View 2 Repliesi have a table that contains 3 forign keys, 2 of them from the same table when i make Delete Rule Cascade,this error message appears
'Customers' table saved successfully
'Order' table
- Unable to create relationship 'FK_Order_Customers1'.
Introducing FOREIGN KEY constraint 'FK_Order_Customers1' on table 'Order' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors. what is solution,as i want when i delete data from master table ,all dependent (child) data automatically deleted, so i use Cascade.
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
View 2 RepliesI have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !
Here's my scenario:
I'm using the ASP.Net Membership provider, but I don't want to allow system administrators to DELETE any users. Instead, I simply want to mark them as locked out (aspnet_Membership.IsLockedOut) of the system so they can't log in when an administrator assigns them to a role titled "Inactive". Make sense? Right now my trigger isn't throwing any errors, but it's not working either. Here's my trigger (which is on the aspnet_UsersInRoles table):

I have an UpdatePanel with ContentTemplate specified. When page loads, user can do some AJAX work in other part of the page. Then, after that work is finished, I would like to update only content inside UpdatePanel, but without pressing any buttons etc. I should be done automatically using JavaScript when previously started AJAX work finishes. How to do it without manual clicking on the trigger button?
EDIT:
Ok, I've followed that _doPostBack rule, and whole page is posted.
<asp:UpdatePanel ID="panelAttachments" runat="server">
<ContentTemplate>
........
</ContentTemplate>
</asp:UpdatePanel>
<input type="text" name="test" onchange="__doPostBack('<%=panelAttachments.UniqueID %>',''); return false;" />
</td>
My issues here is that this does not compile. I get "A control with ID 'LinkButtonRemove' could not be found for the trigger in UpdatePanel 'UpdatePanelFiles'." What I am trying to do is have two buttons in the item template. One that updates just the ITEM and one that updates the entire DataList. "LinkButtonRemove" is what I want to update the entire datalist. Any ideas on why this isnt working? Or how to do what I want to do?
THE SHORT VERSION:
UPDATEPANEL1
-DATALIST
--ITEM
---UPDATEPANEL2
----CONTROLS
I want one control to update the item updatepanel only and the other to update the entire datalist.

I have a button is inside a another table(s) inside the update panel.
<Update panel>

I would like to add a button to Update panel's trigger. But am getting an err says "Update panel can not find the button which trigger it".
I am getting "Sys.Webforms.PageRequestmanagerParseErrorException: This message recieved from manager could not be parsed. Common cause for this error are when response is modified by response.write"
I have a gridview with multiple checkboxes, sometimes 40+. I want the checkboxes to call a .net function in the code behind when clicked. Normally this would be simple if the checkboxes were outside of the gridview. But because they are in the gridview and I don't know how many there are, I don't know their id's before runtime.
I am at the point right now that when you click a checkbox, a jQuery script returns the id and value of the checkbox. Unfortunately, I don't know how to pass the value to a function - that will in turn update another gridview. AFAIK my only option is to get the id's of the controls (checkboxes) before page load and to programatically add then to the update trigger portion of the update panel. Is there any other way to say 'if any checkboxes are clicked, run this'?
i have 2 dropdownlist on my asp page.first dropdownlist value gets selected from a pop up window.now i want to fire an event from the drop down list as the drop down list index changes.The dropdownlist is in update pannel and i want to invoke the server side event of dropdownlist so that the other dropdownlist can be populated.
How can i invoke dropdownlist server side event from the clientside(javascript) so that the ajax functionality can be acieved as my dropdownlist is in update panel.
I need to render a chart control inside UpdatePanel, I have done this part.
The difficult part is that now I need to pass parameter/parameters to server side and grab it in code-behind
so that I can use this information to render the chart.
The parameter/parameters can only be grab in client side by javascript since it is jQuery.data().
I am trying to work around this by saving it to a hidden field, that is not neat though.
I have following code and when I select from my drop down list the progress controls do not show and my grdiview is not being filled either. If I leave out the update panel from my code things are working fine.

By default the postback of child controls will trigger update panels' update.
How can I avoid the same?

View 1 RepliesI have an updatepanel in masterpage and information on a repeater within the panel. I want to update this information from the content page, when a user clicks a button in the content page.

I tried this but since button control is in the content page compiler can't find the control.
I need to do a partial update of a page using an UpdatePanel but I want to throw it using onkeydown. Is there a way to do this by creating a custome asyncpostback trigger.
View 4 RepliesI have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.

I am trying to use SqlDependencyCache buthave come across a problem that I wouldn't have thought was unique. We have a InformationDatabase which uses a combination of its own tables and views to other databases on the same server. One of these views points to our HRDataWarehouse database. My stored procedure obviously uses this view to get its information but because the table change is happening on the HRDataWarehouse table the notification is not being sent to my app and as a consequence the cache is not removed.
Is there a tidy way of doing this or do I need to create a trigger to update a table in my informationdatabase and then have a listener on this with a removecache callback delegate added to the cache object?

So how I can get the value of the file once the button click?
I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.
I am trying to trigger a update planel when a user clicks on an button on a GridView. Once the button is pressed the id of the record gathered and then more information will be gathered and sent to lbl.Text in updatePanel1.
