<object id="s"
classid="http:WindowsControlLibrary1.dll#WindowsControlLibrary1.axUserControl11" height="300" width="300" VIEWASTEXT> </object>
this is the code what i am using but after running the app nothing is getting displayed
I have the following code:
<object runat="server" id="test1" type="application/x-shockwave-flash" width="2000" height="1000">
<param name="movie" value="Finance/Averdaf.swf" />
<param name="quality" value="high" />
</object>
when running the above asp.net gives an error saying An object tag must contain a Class, ClassID or ProgID attribute. What can I do about this? I need to access the object from code behind because I might change the value path to something else at runtime.

I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control

i am trying to enter a value into a texbox that is placed inside a user control called CollectionRequest. i have referenced this user control in my code behind and created an instance of it but i seem to get the above error when i try to enter some manual text. code as follows:
protected CollectionRequest collReq;
protected void Page_Load( object sender, EventArgs e )
{
collReq = (CollectionRequest)LoadControl("~/CollectionRequest.ascx");
TextBox _txt_address = (TextBox)collReq.FindControl("txt_Address");
_txt_address.Text = "thisi is an address";
control has been referenced in source file
<%@ Reference Control="~/CollectionRequest.ascx"%>
i am caling this code in my Approval.ascx.cs code. both the user controls are displayed together in the default.aspx page one above the other.
I have a page on which I placed a user control. In this page I create an object ("FilterState") that maintains some state information. There are controls on the page which alter and read the FilterState, and the user control needs to be able to alter and read this same instance of FilterState. Meaning that there is code inside the user control that needs to refer to this object and manipulate it.I'm stuck on how to share the same instance between the page controls and this user control.
If I declare a FilterState object as a property of my user control, and set this property value to the instance I created in the page code behind, I'm assuming that it's really just getting a copy of it.
I have a user control inside a repeater. I am binding a collection of objects to the repeater.
My user control has a public property to retrieve the object (setobject)
How do i pass each object through to the user control and not just the object property value? What is the syntax to do this?

I have a gridview inside a user control bind to an object datasource. Now I want to bind the object datasource with a parameter from parent page.
For this purpose I defined a public property in user control but how do I pass it with object datasource ?
I am calling from parent page like
myusercontrol.parameter=querystring["id"];
How to bind object datasource with my parameter ?

If I develop a Windows User Control and host it inside an aspx web form, does the user's machine accessing the aspx page needs .NET Framework?
Does the Windows User Control hosted inside an aspx or web form requires any downloading of the control similar to an ActiveX control? Or Is it rendered like a HTML page?
I have a website in php which is using 4 frames(top, left, middle and right). The middle frame contains the web user control coded in asp.net. Now, in the right frame( which is coded in php ) some javascript contains the id of the items selected in right frame. I need to get those ids to the middle frame on asp.net user control.
View 1 RepliesI am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
<object id="myBrowser" classid="http:MyBrowser.dll#MyBrowser.UserControl1" height="20" width="400" VIEWASTEXT></object>
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.
I've got a listview on a control. Each row comprises a checkbox and another listview.
The outer listview is bound to a property on the control (via a method call, can't set a property as a SelectMethod on an ObjectDataSource it would appear) which is lazy loaded suchly:
[Code]....
The reason for the use of viewstate is this:
When an one of the checkboxes on one of the outer list view rows is checked or unchecked I want to modify the object that the ODS represents (for example I'll add a couple of Charge objects to the relevant Product object) and then rebind.
The problem I'm getting is that after every postback (specifically after checking or unchecking one of the rows' checkbox) my viewstate is empty. Thiss means that any changes I make to my viewstate'd object is lost.
Now, I've worked out (after much googling and reading, amongst many others, Scott Mitchel's excellent bit on ViewState) that during initial databinding IsTrackingViewState is set to false. That means, I think, that assigning the return from GetWebServiceProductLineChargeDetails() to the ViewState item in my Property Get during the initial databind won't work.
Mind you, even when the IsTrackingViewState is true and I call the Property Get, come the next postback, the viewstate is empty.
how I keep the object referenced by the ObjectDataSource in ViewState between postbacks and update it and get those changes to stay in ViewState?

View 1 RepliesWe have a website portal hosted in Windows 2003 server. For security reasons we are using different windows Login user say (xxxx) for signin other than Administrator. Now with this user (xxxx) name I installed .net Windows Application. It was working fine. For some reasons I renamed the original windows Login user(xxxx) to different say (yyyy). Now this .net Windows Application is not working with (yyyy) and even it is not allowing me to uninstall it.

my app gets data from sql server using windows authentication but when i create a virtual directly as part of the deployment, the user that tries to authenticate against sql server is ASPNET rather than the windows user as a result authentication fails. I change the "Directory Security" setting in virtual directory properties to disable Anonymous access and leave Windows authentication checked but no luck.
