The problem is that I'm using the SortExpression property of the gridview's databound item. The sortExpression property only takes that column name to be sorted so how can I add this Cast(field As Int)??

Try casting in your select
select column1, column2,CAST(columnn3 AS INT) as column3 from table
This will return an int column to your grid, problem solved.

Thanks a lot, I think this is gonna work.

Thats what I said - do the cast in the query, it then returns the correct datatype.

Your design is broken. Why you need to keep prices in NVarchar field ? How are you binding this grid view ? Using a DataTable ? If yes, after filling the data table, change the column type to integer or double. So gridview can sort it correctly.

I need to know how can I bind my gridview from a pop up window?
I have a gridview on a parent page and then a user can open a pop up window to perform some changes on the gridview in the parent page after that he closes the window. Right then I need to bind the gridview on the parent page to view the changes that the user did from the pop up window.
How can I do that?

OK so you want the following to happen:
User views gridview in mainpage
user edit gridview in new window
user views gridview in mainpage with updated values.
The thing is when the new window closes its not very easy to navigate a user back to the mainpage and then refresh that page to reflect the new changes.
Instead of opening a new window(which may be blocked by pop-up blocker) keep them in the same window and user query string to transfer the values.

thanks for the repy, but there is no way I can do all the editing on the same page. The only way is to use a pop up window.
Is there any other solution for this?
|
|
|
|
|
No, because as soon as you open a pop-up window your application is split in two and they can now continue navigating around the mainpage even with the pop-up open.
best to keep it all in the same window anyway

actually i am taking value from one page to other page using sessions .
but i want at secont page that if the value of session["s1"] ==2 to webcontrol should be generate two times.and it ==3 then usercontrols should be generate 3 times .so i have to apply condition :
if(session["s1"]==1)
{
}
if(1<session["s1"]><=2)(error)
{
}
now i get error:
Operator '|' cannot be applied to operands of type 'bool' and 'int'
what should i do.
thanks

sacc1.Value = s18;
Response.Write(s18);
string s = Session["child"].ToString();
//Response.Write(s);
//Response.Write(s19);int.Parse(Request.Form["schild"])==1
if (int.Parse(s)== 1)
{
Session["a"] = ctcchild1.name;

I'm not able to understand why you are doing in this way.
How do you know that total number of user controls you are creating.
Because, if you are using if there always will be a limit.
Why cant you do something like below
<br />
int totalControl=0;<br />
if(Session["child"]!=null)<br />
{<br />
totalControl=int.Parse(Session["child"].ToString());
for(int curControl=0;curControl<totalcontrol;curcontrol++)><br />
{<br />
}<br />
}<br />

If you aren't sure about the session content, the above method is not secure as it may throw "FormatException" if session has an invalid value. Here is a safe method
if(int.TryParse(Session["child"].ToString(),out totalControl))
{
}

Thanks Sherin
its working .ya you are right .plz tell now how i can take the values from user controls .and how i can retrive the values at next page .
