postback

问题 This is a absurdly common issue and having exhausted all of the obvious solutions, I'm hoping SO can offer me some input... I have a UserControl inside a page which contains a repeater housing several controls that cause postback. Trouble is, all of the controls inside of the repeater never hit their event handlers when they postback, but controls outside of the repeater (still in the UC) are correctly handled. I already made sure my controls weren't being regenerated due to a missing if(

问题 I'm calling a partial postback from javascript like so: function GetPolicyClick() {"__dopostback('UpdatePanel1', 'PostCall')";} It does 1/2 of what I need it to. It does call a partial postback, just for my UpdatePanel. Now the tricky part. I'm trying (somehow) to reference the second argument of __dopostback in my code behind. This does not work: Private Sub UpdatePanel1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdatePanel1.Load Dim MyArg As String = Request("_

问题 I am experiencing an interesting issue. We are running a website using masterpage and in one of the pages, I need to create an update panel that will display group SSID on completion.

问题 How can I retrieve a Button custom attribute after the attribute value has been changed using javascript?

问题 In IE 10, when a drop down list selected item is changed, nothing happens. It doesn't post back. All other controls work except for drop down lists. It appears to work when I switch to IE 10 compatibility mode. 回答1: Scott Hanselman explains this on his blog. http://www.hanselman.com/blog/BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition.aspx 回答2: Do you have the ASP.net Hotfix for IE10 installed? 回答3: Ok, this was a weird issue.

问题 I have an application that is working fine at my local end but when I host it on server, not a single button's click fires. I am getting the Following error: Error: WebForm_DoPostBackWithOptions is not defined I don't understand why I am getting this error as I updated the bin folder Ajax dll and I have installed framework 4.0 on the server but still iI am getting that error. I have already tried the following link: WebForm_DoPostBackWithOptions is not defined 回答1: i had this problem before,

问题 I have a user control which contains several buttons, depending on the button pressed a different control is added to the page (lets say button 1 adds a TextBox, button2 adds a label). I have code along the lines of: protected void but1_click(object sender, EventArgs e) { TextBox tb = new TextBox(); tb.ID = "tb1"; paramsCtrlDiv.Controls.Add(tb); } protected void but2_click(object sender, EventArgs e) { Label lb = new Label(); lb.ID = "lb1"; paramsCtrlDiv.Controls.Add(lb); } I then have a

问题 As I understand it, partial page updates with ASP.NET AJAX cause the JavaScript pageLoad() event handler to be invoked. My question: Is there a generic way of determining in JavaScript from within the pageLoad() function... i) If the postback was a partial page update or not. ii) If so, which panel was updated. My application uses a combination of .NET UpdatePanels & Telerik RadAjaxPanels. I'm looking for a generic (preferably JavaScript) solution which doesn't require me to specify a unique
