Hi,
I have a master datagrid in an asp.net page. Selecting a record in the master datagrid loads the details datagrid. This worked fine as long as I had both the datagrids on the same asp.net page.
Now I moved the details datagrid to a seperate asp.net page that I included in an IFRAME element in the asp.net page that contains the master datagrid. On doing this I have taken care that when a record is selected on the master datagrid the id is passed to the details datagrid in the IFRAME.
So selecting a record is now properly loading the data in the details datagrid in the IFRAME page.
Both the Master and the Details datagrid have paging enabled.
Now after using the IFRAME I am facing the following problems:
1>
I select the record in the Master datagrid and the Details datagrid loads with paging in the IFRAME. If I click on any of the pages of the Master datagrid, paging has stopped working properly : the postback takes place but the next page is not loaded for the datagrid.
2>
If I click on any page no. of the Details datagrid in the IFRAME I get the following exceptiion:
Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount.
The paging for the Master Datagrid works fine if I do not have the IFRAME element
The paging for the Details datagrid works fine if I independently load the page with the required params passed.
In case if anyone has faced such a problem before and knows the solution please let me know
Thanks in advance 
Sid

The Iframe's view state will not be maintained. Why do you have to use an Iframe? If you need to refresh only part of the page then use AJAX via the Atlas toolkit or other method. I would stay away from the iframe unless you like headaches.

I had create data bases with one table. I add a data connection to the data base from Visual Studio 2005. I drag the table to default.aspx form. When I click on the small arrow in the right of the “GridView Task” I can’t see Enable Deleting.
N.B: I can see the data when I run the project in the default.aspx form.
What is the most case of this problem?
Thanks

Hi,
I'm trying to make sense of what to do!!
I have the following SQL statement in a stroed procedure:
SELECT
OrderItemID_PK,
WineID_FK,
OrderItemUnitPrice,
OrderItemQty,
OrderID_FK
FROM
OrderItems
WHERE
OrderID_FK = @OrderID;
I only need the wine ID to populate the Wine object. In my DA class I did it like this:
// Do connections and stuff here
while (dr.Read())
{
OrderItem objOrderItem = new OrderItem();
// Populate other fields
Wine objWine = Wine.GetWineByWineID(dr.GetInt32(1)); // Related Wine object
objOrderItem.OrderItemWine = objWine; // Required
}
OrderItemWine is a property in the OrderItem class that sets the Wine object. I declared the Wine object in the OrderItem class like this:
private Wine m_Wine;
And the property that sets this Wine object in the OrderItem class is:
public Wine OrderItemWine
{
get { return m_Wine; }
set { m_Wine = value; }
}
Like this I can retrieve Wine information, now how do I get the wine name into my gridview, if I didn't define a Coloumn as such for the DataField property??
Please help.
Regards,
ma se

You can try and add a separate function into the datafield template, that calls the name of the wine, using the id you got from the select query, for that specific field.
EG: As the following into your
GetNameForID(wineID) //Id for the wine name you want to add here
or how about using parent/child relationship repeater or datagrid?

Why not join the table with the wine name in your stored procedure and add the column to you grid???
The other option is to add a template column with a label. Then use the ItemDataBound event of the grid and populate the label via code. However, I would think the first method would be much more efficient and simpler.
//inside the itemdatabound method
DataRowView dr = (DataRowView) e.Item.DataItem;
//something like this
LabelWineName = objWine(dr["WineID_FK"]).name;
Note that if the wine class is make a database call then you are really making a mistake. The join in your original proc would be much more efficient.

Thanks for this, but then what is the use of having class relations?? Or am I missing the plot her??

Yeah, you are missing the point. With an ASP.Net application all of the server side code has to run between postbacks. In other words 99% of your code is executed in < 1 second of time. How many class objects can you instantiate during that time interval? Not many. Even when I only working with only one database record I usually use a structure instead of class because it has less overhead.
I have been programming ASP.Net applications for 5 years now and have coded about 25 applications. Most of them have only a couple class files, not including our base class.

Hi! Is there a method to unregister client script block in ASP.net 2.0.
I'm using ClientScript.RegisterStartupScript to register client script which needs to be unregistered based on a condition.
Many thanks.

just use ClientScript.RegisterStartupScript(page.gettype(), "sameName", "");
problem solved.

i have created a guestbook module. it contains many guestbooks.
Each guestbook contains messages.
There is a guestbook detail page, showing guestbook details (name, start date, end date, ....) and messages (with paging of course). I found when pagesize is 400 (and there are 400 hundred message or more), then all buttons (with postback) in the guestbook detail page doesn't work.
after i click it, the page will show error "can not find server", as we usually encounter when we open a browser with no internet connection or the address we type is incorrect)
