One easy method would be to store the data in session (this will work for a data table or data set) then bind it to the grid. Check to see if the data exists in page load and bind it. Then you don't have to requery the data.
Normally, I would think the back button would cause the page to reload. But I guess it is.

In some cases 10,000 or more records will be in the result. If I use a session variable to store the result datatable would that be potential resource hug on the webserver?

That depends.
If you have a master page and or base page then when any page other than the detail loads, you can clear session to make sure it is gone in the page load in only one place.
If you do not have a master page or a base page then removing the item from session might be a bit tricky.
If you have 1-5 users at a time you should be OK.
How much you can store in session depends on your IIS settings, hardware and number of users. You can have multiple aspnet worker process and the amount of ram each process can use is configurable.
One easy check would be to open the task manager and go to the processes tab (show from all users) check the w3wp.exe process(es) and see how much ram they are consuming.

But during the runtime it showing the alert message as null.

Can you try adding the javascript in your code behind? OnPageLoad do
btnSaveCom.attributes.add("onclick", return validateParameter('" + txtParam.ClientID + "');");
If you need to. You can create a second javascript method right in your aspx page.
for example
callValidator(clientId)
{
var paramname = document.getElementById(clientId);
validateParameterWithParamInsteadOfId(paramname);
}

As Todd suggests use code behind
btnSaveCom.OnClientClick = string.Format("validateParameter('{0}')", txtParam.ClientID);

use
btnSaveCom.Attributes.Add("OnClick","javascript:return xx('" + btnxx.ClientID + "');");
in the code area.
But you cant alert the parname as its an object. write
alert(paramname).value instead.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

I don't know if you can do that. Just make a separate web. Any information you need passed between the to can be put in the database or sent via query string. If you do find out how to do this I would be interested in the solution.

Just add a certificate to the whole site. Your links should be http:// links normally. When the user enters the checkout process, just switch to using https:// links...thats all there is to it. You buy SSL certificates for a domain...not really a site. Once its set up for a site on that domain, all you have to do to switch between SSL and non-SSL is change the protocol of your links. You will probably also want to set up some logic in your site to prevent access of secured pages by http.

Hello..i have a check box on my content page i want to access this in aspx.cs page..
Thanks..
|
|

buy a book on ASP.NET and follow the examples. Even if I explained this to you in depth, you're going to get stuck again if you don't understand the fundamentals and lose a lot of time waiting for answers here that you can understand.
The checkbox has a name property, you access it by it's name.

When you add controls dynamically, their viewstate is not restored unless you add them before page load, because it's just before page load that viewstate is restored.

Hi.
In a web form I have 2 user controls.
In one of them I have some textBoxes, and in other one By clicking a button in webform, I need to read the Text property of TextBox of first usercontrol.
But, by clicking the button, the text property is empty. It seems that by PostBacking the webform, usercontrols reLoaded and the stste of them not saved

When do you check the value ? Does your code ever set the value ?

Gosh, do you believe that you answered my questions ? Where in your code do you check it, and does your code ever set an initial value anywhere ?

Sorry! the TextBox is not knly.
I create it an some other controls (I don't know how many, it depends to user request) are created dynamically in code and add to a table control. by clicking the button I iterate throw rows in table, but the the table is without row, but before click it had.
2 userControls, first one is in second one and there is a button in second one, and the second one is in a web page.
Thank you for your attention
Best wishes

Hi, recently I've been updating my website on my computer and then I copy the pages that I've updated and place them on the server but then I'll have to request these pages from the browser the first time coz it would be slow the first time coz they are not precompiled.
So, I was thinking of precompiling these pages only and not the whole website.
I don't want to precompile the whole website coz the web.config file and the app_data folders on my computer are different from those on the server. So, how exactly can I do that?

Why did you ask if you didn't want the answer ?
What you're asking is dumb anyhow - so it's a bit slow the first time, because it's compiling. You want to do extra work to spend the time compiling locally in order to save the same time on the server ? Just get over it - the first page request takes a few moments. So what ?
