Button click JScript window has wrong request.QueryString
-
When I click a button, I want to pop open an new window which tells the user what records they've udpated pertaining to a certain ID. The request.QueryString() pulls in the name of the button, and not the ID. I've go this in the Page_Load: btnUpdateBudget.Attributes.Add("onClick", "window.open('UpdateBudgetConfirm.aspx?ScheduleActivityID='+this.value,'','width=500,height=300,left=200,top=200');") ...and this in the click even of the button: btnUpdateBudget.Attributes.Add("onClick", "window.open('UpdateBudgetConfirm.aspx?ScheduleActivityID='+lblSAID.Text.ToString(),'','width=500,height=300,left=200,top=200');") Is it something with the this.value?

If you have a server click event on the button, you can't add an onclick attribute to it, as the server click event uses the javascript onclick event. The javascript in the first code puts the value of the button in the querystring. This is neither the name nor the id of the button, it's the caption of the button. If you examine the html code of the page, you will see that the caption of the button is in the value property of the button. The javascript in the second code looks strange. It looks like you have tried to use asp.net code in javascript. The properties of server elements does not exist once the elements have been rendered to html. In javascript you can only use the properties of the html elements that is the result of the rendering. --- b { font-weight: normal; }

I used something very similar to this with a dropdownlist selectedindexchange event, and it worked. I figured I'd try it here with a button click event. Any suggestions on how to get this to work?

The page that has this button, "Update Budget", has the querystring value already that I want. I put that in a label, lblSAID, when the page loads. If I could put request.QueryString("ScheduleActivityID") in the javacode, that'd be great, but it looks like I have to assign it to a variable first. this.value simply puts the value of the button in the querystring when going to the pop-up window

Hmmm..when I try to do "View Source" notepad just hangs. If I use anything else besides this.value in Page_Load, then the popup window won't show. When I do use this.value, then nothing in the button_click handler works anyway. Any other suggestions? Thanks!

Empty the Temporary Internet Files, and lower the maximum size of the Temporary Internet Files folder to a reasonable value, like 10 MB. The default value is a certain percent of the entire hard drive, which comes to a ridiculously large value with the sizes of todays hard drives. If you use anything besides this.value that is correct javascript code, the popup window will show. Like this.tagName, this.id, this.name, window.location.href, 'hello', 'anything'... As I said in my first post, you can't use the onclick property when you have a server event that handles the click, as the server event uses the onclick property. --- b { font-weight: normal; }

It's not Java code, it's Javascript code. You can get the value from querystring in javascript: Javascript: querystring[^] --- b { font-weight: normal; }
Guffa, So, if I use only the following in the Page_Load (nothing in the button click handler), the window does pop-up, but nothing in the Request.QueryString(): Dim strSAID As String = Request.QueryString("ScheduleActivityID") btnUpdateBudget.Attributes.Add("onClick", "window.open('UpdateBudgetConfirm.aspx?UBID='+'strSAID.ToString()','','width=500,height=300,left=200,top=200');")

The url of the page you open in the window will look like this: UpdateBudgetConfirm.aspx?UBID=strSAID.ToString() If you want to use the value of the strSAID string, you have to concatenate it with the string containing the javascript. E.g.: ...aspx?UBID=" + strSAID + "',','width... --- b { font-weight: normal; }

I tried this, but now...no pop-up window: btnUpdateBudget.Attributes.Add("onClick", "window.open('UpdateBudgetConfirm.aspx?UBID='" & Request.QueryString("ScheduleActivityID") & ",'','width=500,height=300,left=200,top=200');")
That is because you have placed the value from the querystring outside of the javascript string. Your javascript code will look like: window.open('UpdateBudgetConfirm.aspx?UBID='42,'','width=500,height=300,left=200,top=200'); Put the value inside the string, like the code I showed you in my previous post. --- b { font-weight: normal; }

Thanks Guffa! That was the trick. Here's what I used: Dim strSAID As String = Request.QueryString("ScheduleActivityID") btnUpdateBudget.Attributes.Add("onClick", "window.open('UpdateBudgetConfirm.aspx?UBID=" + strSAID + "','','width=500,height=300,left=200,top=200');")
