Web Forms :: Opening The Aspx In New Window While Retaining PreviousPage.FindControl Method?

Jul 20, 2010

I want to open a aspx page in new window.

I am openning a web page using JavaScript open .

StringBuilder cstext3 = new StringBuilder();
cstext3.Append("<script type=text/javascript> function OpenPreviewPage() {");
cstext3.Append("open('Preview.aspx');");
cstext3.Append("} </script>");

And executing following at button click on .cs page

protected void btnPreview_Click(object sender, ImageClickEventArgs e)
{
/*This will call the OpenPreviewPage method of java script from .cs file */
string javaScript =
"<script language=JavaScript>
" +
"OpenPreviewPage();
" +
"</script>";
RegisterStartupScript("ShowPreviewPage", javaScript);
}

The problem is the PreviousPage tag in preview page is null.

repPFareDetail = PreviousPage.FindControl("repFareDetail") as Repeater;

Is there any other way to open the aspx in new window by retaining the PreviousPage.FindControl method.

Retaining PreviousPage Information After Postback?

Jul 29, 2010

I'm using the asp.net PreviousPage functionality and cross-page postback. The problem i'm running into is that if I have any postbacks on my page, the PreviousPage information seems to be lost. I don't want to put it in ViewState because that will be quite large. I've thought about Session, but I don't want the data to persist after i've moved on to another page, and I really don't like the idea of putting code in all my other pages to delete old session variables.

Web Forms :: Get The Value Of A Textbox Using PreviousPage Method Along With A MasterPage?

Aug 20, 2010

I'm trying to get the value of a textbox using the PreviousPage method and the previous page utilizes a MasterPage for the page's layout. I've read through many forums laying out the ground work on how to do this, but for whatever reason I am just being unsucessfull in getting this to work in my project.

Mark-up of previous page using a master page template:

VB Code-behind page for second page:

What really confuses me is that when I step through the code it goes all the way through the if statement but never gets the text value from the previous page.

Javascript - IE - Get Popup's Opening Window When Using Window.open (url)?

Sep 23, 2010

we are running a click-to-call service, my idea is basically like this: website have a link on their page, when the link is clicked, a web page(say it is popup.aspx) hosted on our server is popup, user can input their phone number, and click "call me" button to let the website call him. In the button click event, I want to get Request.UrlReferrer, then query the db to get website's phone. But in IE, Request.UrlReferrer is null(firefox is ok, not test chrome yet),my question is how to get opening window' url in IE? we put popup.aspx on our server because

our client website is not force to use asp.net. we have the control what we put on the popup window, and can modify the page just from our side, if we put the pop window on our partner's side, if we have 100 partner, and we change the page's design, we will notify everyone of them to change this, change that. we can implement a statics system to know how popup a day, which site is most popular,etc

Easiest Method To Build Where Clause From Checked Items In DataList Of PreviousPage

Jun 25, 2010

I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table. The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.

So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items). Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable. Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?

Web Forms :: FindControl On Default.aspx In MasterPage.CodeBehind

Dec 11, 2010

I was wondering if it is possible to find a control in a standard web form that is using a masterpage.

So for example I have two pages - default.aspx and information.aspx. Both these web forms have label controls (lblDefault and lblInfo respectively). This information is stored in a database along with the content that the label controls should be populated with. Instead of having to program a method to retrieve the content text from the database for the relevent controls on these two pages would it be possible to find the controls in the masterpage codebehind file - something like Page.Form.FindControl("lblDefault")? So for each webform using a masterpage a check is done to see if any of the controls should be populated with content from the database.

Opening A Form In New Window

Sep 22, 2011

Trying to open up a form in a new window while passing some values. It is working, but it is client side (My ASP co-worker finally grabbed the reigns and implemented a bit of his ASP magic to open the form and transfer the values.) But it's so messy, and I hate the fact that I have been bested by old technology.

I was doing this client side before, using window.open and transfering the variables in the URL, but I was getting flack for doing that. So I looked at alternatives and found session variables, which you set server side. So now we want to open the form. I tried the following (individually): Response.Redirect("OtherForm.aspx") and Server.Transfer("OtherForm.aspx") Which replaced the original form in the open window instead of a new window.

I spent a lot of time searching for a solution but the answer keeps coming back to "Just inject some JavaScript to open your form." Is there no "normal" way to open a form in ASP.NET. In any case I guess the real question I would like to ask is what is the best way to open a child form from a parent form?
