I have had this problem and found that there is no way to persist changes. If you can not use Ajax and set the style with server code, there is one hack you can do.
You can save the css values in a hidden element.
For example you could have a hidden span tag
<asp:textbox id="cssValue1" runat="server" style="display:none" xmlns:asp="#unknown">
use javascript to change the value of the cssValue1 when you change css of control.
During the postback set the css of your element to the value you now have access to.
myControl.CssClass = cssValue1.Text;
Do you get what I am saying?

What could cause a Request parameter, passed in a redirect, to go missing? I pass and retrieve the parameter using the following lines of code, yet in the target page, the parameter is empty.
Response.Redirect("~/ConfirmStaffComment.aspx?refNum=" + commentRef, false);
lblFeedbackReferenceNum.Text = Request["refNum"];
My brain fart. 
The commentRef was out of scope when I redirected. In the debugger, I checked it was populated, in scope, and assumed it would still be when I redirected.

I've had that happen a few times in the past. Kind of a bugger to find sometimes

I actually made it out of scope myself, by adding an extraneous 'string' type declaration at the left of an assignment to the commentRef. Even worse.

No, not without seeing any code you have tried thus far...

I have tried a lot but here are the main ones:
(1)
function showDirectory(){
var oShell = new ActiveXObject("WScript.Shell");
var commandToRun = "C:\\Windows\\Notepad.exe";
oShell.Exec("C:\\Windows\\Notepad.exe");
}
//but I don't wont an activex
(2)
function showDirectory(){
SystemProcess spCommand = new SystemProcess();
spCommand.runCommand("C:\\WINDOWS\\notepad.exe");
}
(3)
//this was done in the .aspx.cs file
protected void Button1_Click(object sender, EventArgs e){
System.Text.StringBuilder myStringBuilder = new System.Text.StringBuilder();
myStringBuilder.Append("\n");
myStringBuilder.Append(@"<script language=""javascript"" type=""text/javascript"">\n");
myStringBuilder.Append("SystemProcess spCommand = new SystemProcess();");
myStringBuilder.Append("spCommand.runCommand(C:\\WINDOWS\\notepad.exe);");
myStringBuilder.Append("</script>\n");
string myString = myStringBuilder.ToString();
if (!this.ClientScript.IsStartupScriptRegistered("startCatia"))
{
this.ClientScript.RegisterStartupScript(this.GetType(), "startCatia", myString);
}
}

Is there a requirement you have for using javascript? You ought to consider if user has javascript disabled.

now these computer are the clients and I want my program to launch there notepad just by clicking a button
that's it ....

Why are you trying to do this?
Is there no other way?
Even if you are successful, it will be a hack. Scripting done inside the browser is not meant to be able to launch an executable for obvious reasons.

You might want to look into how Apple's iTunes links work.. They are just an ordinary link as part of the Apple website but I assume they call some sort of script.. I don't think it's ActiveX because it works in other browsers aswell as IE.

Hi,
I have a DetailsView control on my page that is the details page of a master/detail set. It grabs the record id from the query string that is passed from the master page. I also have a search box that lets the user search for a new record via an OnClick function. This function just sets the SelectCommand of my SqldataSource to a new query that grabs the text of the textbox used for searching.
It all works great until I hit the edit (which is displayed via the "AutoGenerateEditButton" property) button. When it goes into edit mode the DetailsView looses the record which it currently has (the one from the search) and reverts back to the first record that came from the QueryString.
I have called the DataBind method after the selectCommand on the OnClick call to re-bind the DetailsView but it doesn't fix the issue.
Any insight would be greatly appreciated.
thanks- Frank

Where you are binding your details view?
If its in page load that could be a problem.
Can you show your page load and button click codes.

Hi Sherin,
Thanks for the reply. I have tried binding on page load as well as other options. I have also just tried using the FilterExpresssion parameter, which works great in the master page, however, because the sqldatasource for the details page already filters the records via the record id, when i add the filter expression it of course doesn't work because it tries to apply both the record id and the search term.
here is the code I'm using:
protected void Page_Load(object sender, EventArgs e)
{
srcDetails.SelectParameters["recordID"].DefaultValue = Request.QueryString["id"];
srcDetails.SelectCommand="SELECT ... FROM dbo LEFT JOIN dbo. on ... LEFT JOIN dbo. on ... WHERE id = @recordID";
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
string val = txtDomain.Text;
srcDetails.SelectCommand="SELECT ... FROM dbo. LEFT JOIN dbo. on ... LEFT JOIN dbo. on ... WHERE name LIKE '%"+val+"%'";
frmDetails.DataBind();
}
thanks. Frank

How do I have a gridview load with a specific row on the displayed page without filtering out all the other rows. ie if I'm showing 10 rows/page, and the row I want to show is the 37th I want it to load on page 4 instead of 1.

Why can't you set the 'PageIndex' property?

That would probably work, but how do I convert the PK into a row number if it's not guaranteed to be sequential?

int pageToShow=Row_Number%Rows_Per_Page==0?Row_Number/Rows_Per_Page:Row_Number/Rows_Per_Page+1
Can you use the above idea?
PageIndex=pageToShow;

My problem is converting the PK for the row into a row number. IF my query returns rows with PKs of: 1,2,4,5,8,12,44..., and I the row I want has a PK of 12, how do I use the PK to get the row number of 5?

There should be some relation between these PKs and the page numbers.
What is that relation?

Why cant you use that 5* as the row number?

They represent every non deleted row in the table being queried. Before any deletion the PK and row numbers would be the same, after some rows are deleted that would no longer be the case. With arbitrary deletes there's no formula that can be used to convert between them. I'm asking if ASP/ADO.net provides any build in function to get the row, or if I have to manually iterate over the datasource until I find it.

The PK is coming from a source that displays a filtered subset of the data in a different order, so row numbers will not be the same.
