You need to use the server-side function: Page.GetPostBackEventReference

and tell it what control's event you want to fire.
The __doPostBack('','') won't fire any client-side events because the first parameter, which is the client name of the control raising the event, isn't set.

Hi stiletto,

now i describe my page more detail, the parent window, i use a button to call javascript function:
<script language="javascript">
function GetDate(CtrlName)
{'color.aspx?FormName='+ document.forms[0].name+ '&CtrlName='+ CtrlName, "Color","width=500,height=400,top=100,left=200,toobars=no,scrollbars=no,status=no,resizable=no");
} to show a child window which contain a list of color.
2.a child window pop up.
3.after i choose one of the color from the childwindow and i click a button (to call javacript:
<script language="javascript">
function ReturnColor(){
window.opener.document.forms["<%= strFormName %>"].elements["<%= strCtrlName %>"].value = "<%= StrSelectedColor %>";

__doPostback("<%= strCtrlName %>",'');
4.the child window closed and get a value(strselectedcolor) from childwindow and put into variable "Ctrl" which is textbox id. AND textbox.text = "strselectedcolor".
All of this is ok if i just the textbox.text.
But i want to change textbox.backcolor, not textbox.text!

Is this a cross-browser application?

If it's IE-only then you should be able to (from your child window):
window.opener.document.all["<%= strCtrlName %>].style.backgroundColor = "<%= StrSelectedColor %>";
to change the textbox's background color.

hi stiletto

sorry forget to infrom you that, the StrSelectedColor is a STRING variable, not COLOR variable.

That's OK the style can be a color name, just change:

window.opener.document.all["<%= strCtrlName %>].style.backgroundColor = "<%= StrSelectedColor %>";
window.opener.document.all["<%= strCtrlName %>].style.backgroundColor = '"<%= StrSelectedColor %>"';

Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error: Cast from type ''''DBNull'''' to type ''''String'''' is not valid. I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL. Is there another way around this? Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan theSpoke Blog Where in the code does it need to go?

table_info('','','','%') cannot return any types
I was recently confirming table_info special cases and discovered the case for getting table_types cannot work. table_info('','','','%') should return a list of table types but it returns a list of empty strings instead: my @types = $h->tables('', '', '', '%'); print "all types:\n", join("xxx\n", @types), "\n"; # should output something like: # "dbo" # "INFORMATION_SCHEMA" # "sys" # and actually outputs: xxx xxx It seems to be down to the following ...

Using '[' and ']' characters...
Has anyone come across the following problem when using PD7.5 on SQL Server 2000? PD7.5 does not generate the '[' and ']' characters for stored procedures. Example: CREATE PROC P_Test AS SELECT A AS [Column A] FROM A_Table Generated script: CREATE PROC P_Test AS SELECT A AS Column A FROM A_Table Thanks in advance, Aiden That's interesting. In 7.5, if I put [[Column A]] in the procedure definition, I get [Column A]. In 8.0 it works correctly. -- Michael F. Nicewarner [TeamSybase] http://www.datamode...

'IN' Clause or 'OR'
Hello, [1]: select * from TABLEA where COL1 IN('value1','value2''valu3'....) [2]:select * from TABLEA where COL1 = 'value1' OR COL1= 'value2' OR COL1='valu3'. TABLEA is a huge table and it has non-clustered index on COL1. Among the above 2 queries, which query will give me the better performance or fast response and WHY?

'or' or 'union'
Hello I was just wondering, in general what is better to use, an 'or' clause in a select or a 'union' to join two selects together. Do both statements create work tables? Many thanks Alex I think OR will be better than union. because suppose u have 3 tables and using OR u can join table a and table b and table c so each table will have only one read. but using union you will join table a and table b and in another query of union u will use table (a or b) and table c so ur one read is more in union .
