Hi,
thanks again for your help.
I've tried your code and the component works fine.
No errors; all casts are OK.
I've added my component to the same test project and again the error occurs.
What I found out: the error only occurs when the component is added from the toolbox to a WebForm (regardless of added by doubleclick or dragged with the mouse). When the WebForm is closed and opened again in the designer, all of my components are processed without error.
My component and the designer are in an extra WebLibraray project. For debugging I use two instances of VS 2005.
The complete declaration of my component:
[
AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal),
AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal),
ToolboxData("<{0}:MyComponent runat=\"server\"> </{0}:MyComponent>"),
ToolboxBitmap(typeof(MyComponent), "MyComponent.bmp"),
Designer(typeof(MyComponentDesigner)),
ParseChildren(false),
PersistChildren(true)
]
public class MyComponent: View, INamingContainer
Any idaes?
Regards
Jürgen

Hi there,
+ Do you get the error right after you add the control onto the web page or after you do something and the error occurs?
+ If you manually add the custom component in the source view and switch back to the Design view, do you still get the error?
+ Do you plan to use the MyComponent with the MultiView control?

the error occurs right after adding the control
minhpc_bk wrote: + If you manually add the custom component in the source view and switch back to the Design view, do you still get the error?
as I wrote, if I open the WebForm with designer all MyComponent controls on that WebForm are displayed without error; so adding controls in the source is OK
minhpc_bk wrote: + Do you plan to use the MyComponent with the MultiView control?
yes, MyComponent is used in a MutliView

Can you reset the Toolbox of VS and see if you keep getting the error? Also, if you still have the error, can you try to debug to see if the VS designer loads the right version of the component assembly as the error type casting of the same type leads me think the designer loads two versions of the assembly.

Every time that I am doing any changes in my code and starts up the debugger it takes a wery long time. When I look in the output window during the startup I can se that the debugger are going through a whole lot of temp files in the c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files\ folder. This part of the startup is what takes the longest time. Is there anything I can do to fasten up this problem. Right now it takes up to 10 minutes everytime I want to start up the debugger. Wery frustrating!

Hi there,
+ Is your solution large enough?
+ Does you dev box have enough resource remaining?
+ You may try debugging your application with the "Attach to Process" option after you recompile the project with the changes.

Hi All,
I have a Package in Oracle, which run around 60 to 70 Minute at Oracle Level ( Due to Huge Numbers of Record )and run fine with no Error, but at Application Level (Application Developed in ASP.NET 1.1 with C#.NET) after 40 to 45 Minute, it gives error "Action Canceled : Internet Explorer was unable to link to the Web Page you requested. The Page might be temporarily unavailable" (There is no ASP.NET error Description ). Any idea about that..............
Please note that my Session Time out is 80 Minutes.
Thanks in advance

I don't know where you set this, but check IIS settings regardin the connection timeout settings or something like that.
The server probably disconnects the client after that time becouse it is taking too long to proccess the request.

how do you find out which button is clicked among many in a page?or what code should you write in page_Load method to find out which button was clicked?
|
|
|
|
|
You may use CommandName property of the Button Server control. Each Button has the unique Command Name. Ok.
Then in Page_Load event, u may check for the Particular button using e.CommandName property.
for ex, if(e.CommandName == "btn1")
Hope it works fine with u.

Jay

You have to make a request to the server. Either by doing a postback, or using AJAX.

I use DropDownList edit DataGrid data, There have 4 columns using DropDownList for edit data. Generally I only want to change one column data. But when I enter editing mode, the all DropDownList’s index change to zero, only I want to change one column! How I set all DropDownList Index default to right value.
|
|
|
|
|
I am not sure whether i have understood the problem correctly but if you want to set some value of the dropdownlist control as selected then this you can do in OnItemDataBound event of the datagrid.
