ReportViewer shows blank on one computer, exporting works OK

Hi guys,

A customer just reproted a problem that's quite strange. They are using an ASP.NET application with a ReportViewer 9.0 control.

The report doesn't render at all (totally blank, although the toolbar is there) but if I export the result the PDF comes out perfectly. If I run it on my computer (and many others), it works fine.

The user is running WinXP with IE 8. [UPDATE: Specifically IE 8.0.6001.18702 update versión 0]

I googled it and found this[^] where several users report the same problem, but no solution is proposed.

Have any of you ran into this?

Thanks!!

Value not toggle in JavaScript alert box

I am writing a custom control - Calendar textbox. In the code of the custom control i have added a attribute by the following code:

protected override void AddAttributesToRender(HtmlTextWriter writer) 
{ 
base.AddAttributesToRender(writer); 
writer.AddAttribute("isDateControl", "true"); 
writer.AddAttribute("ShowCalendar", "true"); 
writer.AddAttribute("maxlength", "10"); 
}

Here I have added the attribute named ShowCalendar.
I have one js where i am calling this above property values as shown below:

base.OnPreRender(e); 
System.Web.UI.ClientScriptManager cs = this.Page.ClientScript; 
cs.RegisterClientScriptResource(typeof(WebDate), "WebControls.WebDate.WebDate.js");

Inside JS..I put the alert box to get the value of the property named
"ShowCalendar"

Shown below :

if (obj.getAttribute("ShowCalendar") == "false") 
{ 
alert(obj.getAttribute("_IsShowCalendar")); 
} 
else 
{ 
alert(obj.getAttribute("_IsShowCalendar")); 
}

Till now no issues ..all fine .. I can see the value of "ShowCalendar" attribute from JS alert box, But when i change the value to true to false or vice versa in the html tag shown below:

ASP.NET

<tsg:WebDate ShowCalendar="false" runat="server"> </tsg:WebDate>

Value is not getting toggled from the JavaScript alert box.

Could you please tell me what the issue , why the value is not toggling?

Format your code using the code blocks.

Have you posted all the relevant code? I don't see any code that actually toggles your property.

In the alert method you are trying to get the value of the attribute "_IsShowCalendar". Can you please let me know if you are adding the attribute anywhere else and if its default value is set to true?

Web service callback

hi,

I needs some clarification for webservice. The scenario is, i have to call a webservice interface. which is performed more than three minutes ( ftp file upload and download process done by that webservice). which is taking some times to complete.

So i used on the webservice proxy object property like

service.Timeout = 1000*60*5

its okay for webservice communication.but until that time we have to wait in our asp page. for that i created separate thread for webservice invoke.( thread is containing the class object is singleton). so when i used timer every time the class has the value or not . if there, i will shown to to the page.

For this way, i have achieve my scenario. but incase, the user can close the page after invoke, in that case data's maintain the entire application ( The data stored in hashtable object as key and value)

Have any option for achieve webservice performing long time?

Using a timer is not the best way.
Call the web service asynchronously.

okay... Thanks for sharing

but the thing is when I added web reference, coudn't get the method start with Begin(BeginHello). Its comes like HelloAsync.

didnt get this type of proxy method automatically

MyService.BeginHelloWorld(AsyncCallback, null);

This is the call back method ok its comes after the webservice execution ,. but have to show that "completed web service" message to page. but in this case, its not reflected to page

void MyService_HelloWorldCompleted(object sender, ForLearnWebservices.localwebserver.HelloWorldCompletedEventArgs e)
        {
            lb1.Text = "completed web service";
            //throw new NotImplementedException();
        }

Calender popup missing

I am trying to implement a calendar popup from a text box.

I used the following plug in ..

http://jqueryui.com/demos/datepicker/#icon-trigger

I have copy pasted the code in the "view source" button in the above link to my webpage.

I can see the textbox, but i cannot see the calender image on the side of text box which is click-able and a popup of calendar because there is no button to click.. why so?

Do i need to download css files ? and add it to my web solution?

In the options of the datepicker, you have something called as buttonImage. Are you having the respective image in the path, in your application?

JavaScript

$(function() {
        $( "#datepicker" ).datepicker({
            showOn: "button",
            buttonImage: "images/calendar.gif",
            buttonImageOnly: true
        });
    });

<add name="NotificationsConnectionString" connectionString="$(ReplacableToken_NotificationsConnectionString-Web.config Connection String_0)" providerName="System.Data.SqlClient"/>

Never saaw that before. No idea why it decided to replace my perfectly workable connection string with something that didn't work.

Any idea what I did to screw it up? I've got no replaceable tokens except for the ones we got at Chuck E. Cheese the other night.

That's ridiculous. It may be all gee whiz cool in their minds, but the deployment replace diddly, so their brilliant thought that it would prevent pointing to the wrong database wasn't quite so brilliant.

Well, I guess pointing to no database whatsoever is kinda sorta prventing the wrong one being used... Poke tongue | ;-P

string myObjectTag = "";
sourceUrl = sourceUrl + "";
sourceUrl = sourceUrl.Trim();

throw new System.ArgumentNullException("sourceUrl");
}

if (isFullSize)
{

Hi,

Is there a way to change the and tags of the master page from a child page?

I want to do the following:
- Add onload, onclick and onkeypress attributes to the master
- Add autocomplete, enctype and action attributes to the master
- Change the master method to POST

The idea is that the page will redirect to the url specified in the after the submit button is clicked.

Thanks and regards,

Rafferty
