ModalPopupExtender from code behind

ASP.NET AJAX Discussion and Suggestions — Tue, 10 Nov 2009 19:49:31 GMT

Hi. I have a ModalPopupExtender on my default page. I have added an asp:Button (btnShowPanel) and used that ID as the ModalPopupExtender's TargetControlID. This works well. Now what I am trying to do is show the panel from code behind instead of having the user click on btnShowPanel. Basically, I have a database query. If that query returns more than 100 rows, I want the popup to show with some text like "Your query returns more than 100 rows. Displaying all of the data may take a while. Do you want to continue?" If they click YES, I want to continue with the code (or run another method). If they click NO, I want to drop out of the method. I'm a newbie, so be gentle. Thanks, Ray Read More......(read more)

Gridview in Update Panel causing full page postback

ASP.NET AJAX Discussion and Suggestions — Tue, 10 Nov 2009 15:14:49 GMT

I have a gridview within an update panel which contains a checkbox (once for each row) which has its AutoPostBack property set to TRUE. My understanding is that ANY postbacks which occur within an UpdatePanel should result in a partial postback of that panel only (i.e. Asynchronous). This is somewhat confirmed by a simple button which also resides in this UpdatePanel which correctly does a partial update with no page flicker etc Because the control is within a gridview I can't set it as a trigger..... <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"...(read more)

" Live" databinding using Ajax

ASP.NET AJAX Discussion and Suggestions — Tue, 10 Nov 2009 00:35:36 GMT

Hi, this is a newbie question. I am used to using gridviews and dataviews with ASP NET 2.0. How do I get the data in, say, a gridview, to update live, i.e. whenever a cetain field is updated in a database? I assume this is possible with Ajax. Can anyone outline the steps I need to take please. Remember I am using ASP NET 2.0. Also, I don't think I even have Ajax installed (never used it at all). Thanks in advance, Garrett Read More......(read more)

Jquery tabs with ajax

ASP.NET AJAX Discussion and Suggestions — Mon, 09 Nov 2009 23:26:58 GMT

Hi, I have been using Jquery tabs with ajax to make ajax calls to the aspx page something like default.aspx?id=1 in Jquery makes an ajax call to the default.aspx page and the aspx page looks for the value in 'id' and sends the response. The question I have is that on the server side, I have been using response.write() and response.end() to send information back to the client but I have seen that if the client opens the link default.aspx?id=1 then he only sees the response text and nothing else on the page. (all the other content in the html is replaced) I was wondering if response.write() is the right method to send the info back.. Because what I was trying to accomplish is to actually append the response text to a server div tag and...(read more)

Question about multiple cascading drop downs using one web service.

ASP.NET AJAX Networking and Web Services — Mon, 09 Nov 2009 21:11:23 GMT

Hi, I've got a page that has three sets of drop down lists that use Ajax cascading drop down extenders. All three sets function exactly the same way, and all three use the same XML file to populate their values. I am wondering if it is possible to use one web service for all three sets or if I need to have a web service for each set? I'm asking because I'm getting strange results when I try this. Everything works fine when I wire up the first set of drop downs. When I wire up the second set it works, but the first set no longer works (the first drop down box shows what I assume to be 'Method Error' - the box is not big enough to show the entire message). If I remove the cascade from the second set, the first set works again...(read more)

Data returned from Sys.Ui.DataView includes __msajaxbindings property, causing serialization to fail

ASP.NET AJAX Discussion and Suggestions — Mon, 09 Nov 2009 20:35:03 GMT

If get_data() is used for a DataView - in this case a complex object graph with nested DataViews - the object cannot be easily serialized to JSON as child bound objects have __msajaxbindings and __msajaxdispose properties that give circular references, causing the JavaScriptSerializer to trip up. For both the root DataView and nested DataView I'm programatically setting the Data property for the DataView (with $dataItem.collection on the nested DataView). Any advise on how to avoid the circular references, and for these metadata type properties to be stripped out? Cheers. Andy Read More......(read more)

Have I done everything possible to solve 'sys' not defined/scriptResource.axd error?

ASP.NET AJAX Discussion and Suggestions — Mon, 09 Nov 2009 17:58:08 GMT

I've done everything recommended by my hosting tech support team (ran the aspnet_regiis commands from the server command line, made sure Compression was unchecked in IIS, and made sure .axd files were mapped to the aspnet_isapi.dll file while 'Verify if file exist was unchecked'. I've implemented the correct Web.config file to the one I'm using. AJAX'd pages still give the errors 'Syntax Error: ScriptResource.axd' and 'Sys is Undefined'. When I look at the source for the page, WebResource.axd (which comes before ScriptResource.axd) does not show up in the error details. The same web.config and bin files work fine on another AJAX site with another hosting company. Thanks in advance for any help Read More...(read more)
