I am writing a web page to show image (image is dynamically generate by .Net charting) in a web. I have used the asp.net web forms URL routing to navigate to this page. Once I use the URL routing the image appear on the page. Anyway this is working fine for normal page browse.

View 9 RepliesI have a link button:
<asp:LinkButton ID="LinkButtonPrint" runat="server" OnClick="OnPrint_Click">
<img src="img/print-icon.png" alt="" />
<asp:Literal runat="server" Text="<%$ Resources:PrintPage %>" />
</asp:LinkButton>
In code behind I add an onclick handler in Page_Load like this:
LinkButtonPrint.Attributes["onclick"] = "StartLoadTracking(this, '" + GetLocalResourceObject("Loading") + "')";
The rendered HTML is like this:
<a href="javascript:__doPostBack('ctl00$LinkButtonPrint','')"
id="ctl00_LinkButtonPrint" onclick="StartLoadTracking(this, 'Loading...');">
<img alt="" src="img/print-icon.png">Print page
</a>
If I click this button it is working OK (it will respond with a PFD file so no HTML is sent back to the browser), but if I click another button on the page (which makes a full postback) the LinkButtonPrint will not have the inner content, it will be rendered like this:
<a href="javascript:__doPostBack('ctl00$LinkButtonPrint','')"
id="ctl00_LinkButtonPrint" onclick="StartLoadTracking(this, 'Loading...');"></a>
If I remove the LinkButtonPrint.Attributes["onclick"] = ... line from Page_Load everything works fine (except my js function is not called, but that is normal).
What am I missing here?
EDIT
This is duplicate of asp.net Link button image not visible after postback.
Actually I have Multiple update panels on page, which update different values on server but the problem is that I have textbox to which I attach javascript class for datepicker on Load event.
But There are other updatepanels before that date TextBox, when I update them first calender image with date control which is in updatepanel disappears. or it remove the calender which is next to the textbox.
txtDate.Attributes.Add("class", "show-week w16em dateformat-d-sl-m-sl-Y");
Before using any updatepanel its like this
After we upfdate any updatepanel control its like this.
But the Date controls which are not in any updatepanel are ok and working.
And in these updatepanels I actually saving values in DataTables and save these DataTables in viewState .... no change in HTML.
I would like to create a website which shows an image and it disappears and then another images appears which then dissappers and another is shown...can someone point me in the right direction for this please?

I tried to mix asp.net 4 webfrom and ASp.Net MVC 3. I add required lines in webconfig, but I've issues implementing route in global.asax
Currently I use several routes for webfroms. routs template are like below
routes.MapPageRoute("Node", _
"article/sport/{nID}/", _
"~/article/articleview.aspx")
I encounter error, when I add below lines to global.asax
routes.MapRoute( _
"Defaultss", _
"{controller}/{action}/{id}", _
New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _
)
I want to know how could I mix ASp.Net MVC routes with webforms routes.
when i run the app i got this error
A route named 'Admin_default' is already in the route collection. Route names must be unique.
Parameter name: name
this is my AdminAreaRegistration

I have a url that I want to map routing to:
[URL]
where tabvalue is one of: "personal", "professional", "values" or nothing.
I want to map it to a route like:
Member/Edit/{tab}
But my problem is - I don't know how to specify such constraints. I'm trying this regex:
^[personal|professional|values]{0,1}$
but it only works when I use url
[URL]
[URL]
and doesn't work for
[URL]
how to specify the correct constraint?
P.S. I'm not using MVC, just asp.net WebForms
Was looking at asp.net mvc complex routing for tree path as an example of how to define a custom route handler for my MVC app. Essentially, I want to give the end user ultimate flexibility in defining the URL for any given page, so I provide them with a field in the interface to specify their own custom URL.
My custom route handler is basically a wild-card handler. It will do a lookup and if it finds a match, map it accordingly. However, if no match is found, I want it to fall back and find the next rule that matches in the global.asax. Is that possible? Or do I essentially need to code the mappings that used to exist in my global.asax into my custom route handler?
I've added a site map path on my web pages. When a page is loaded that is consistent with the site map, the site map path is displayed. Another way to say this is that if the page history is consistent with the site map, it is displayed e.g. Page 1 > Page 2 > Page 3. However when Page 3 is submitted, the history becomes Page 1 > Page 2 > Page 3 > Page 3. This is inconsistent with the site map and is not displayed.Also if you open a page from another page using a hyperlink that is not consistent with the site map, the site map path is not displayed.WHO DESIGNED THIS? (only a retorical question)My real question is, is this consistent with your findings, and if so is there a work around to always display the site map path , or is there a third party control that will always display the site map path, or the actual page history.

View 4 RepliesI am having an issue with people visiting my site using ie8. It appears that some of my pages seem to render, then disappear. It is only happening in IE8. I looked up a few things on the web and found a few bugs within the browser:
http://edskes.net/ie/ie8overflowandexpandingboxbugs.htm
I tried implementing the changes but am still having issues. I suspect it is something within the styles of my controls pages or within the CSS file.
I'm migrating a large number of stand-alone pages into content pages. Most of this involves little more than copying and pasting a GridView from one page into the new page. However, I find that styling disappears in the new project, i.e. the styles (as classes) are still present in the stylesheet, but these classes are no longer applied to GridView table elements. Example, in the old project, once a table is rendered by the GridView, its header row has a class of HeaderStyle, but in the new project this is lost, without any editing of the GridView. Is there some mysterious, built-in mechanism that automatically applies these attributes to GridView elements that I have somehow disabled?
View 1 RepliesI have an asp.net textbox like this:
<asp:TextBox ID="PINPad" runat="server" Columns="6" MaxLength="4"
CssClass="PINTextClass"></asp:TextBox>
It is, as you might have guessed, the text box from an on screen PIN pad. Javascript fills in the values. The page is posted back every five seconds (using an update panel if that matters) to update various other unrelated items on the screen. This works just fine. However, when I convert it to a password text box, like this:
<asp:TextBox ID="PINPad" runat="server" Columns="6" MaxLength="4"
CssClass="PINTextClass" TextMode="Password"></asp:TextBox>
Then whenever the page posts back, the text box is cleared out on the screen and the textbox is empty (though during the timer event, the value does make it back to the server.)
I have a ListView that has a FileUpload control and a button in each ListViewItem. I have an OnClick event on my button where i try and pull information from the FileUpload control, but when I try to access the control all of the values that were set are gone (FileName etc).
What do I need to do differently here to access the information I just entered?
<asp:ListView ID="lv_Uploads" runat="server" OnItemDataBound="GetThumbs" EnableViewState="true" >
<LayoutTemplate>
<div id="itemPlaceholder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
<div style="width:500px;>.......
Code behind:
protected void SaveFile(object sender, EventArgs e)
{
//This always evaluates to an empty string...
string myFile = ((FileUpload)((Button)sender).Parent.FindControl("fu_Upload")).FileName;
}
I have an asp:UpdatePanel in my .aspx page.Within the panel I have placed an infragistics ultrawebgrid control.Upon clicking a button (placed outside the panel) , I have to export the data in the grid to excel.I am using
UltraWebGridExcelExporter(Infragistics object) for this. The export will occur only with full postback.For this I have added a PostBack tigger for the button to the update panel.But once the export is complete, if I change the selected item in a dropdownlist(Autopostback="true") in the same page,the updatepanel gets invisible.

So I got 2 updatepanels on my page. In one there is a Timer which updates for example a label. In the other one there is a dropdownextender. Everytime the timer ticks while the dropdown menu is displayed the menu disapears. I attached the sample code below....any insights on this? And yes, the dropdown and the label need to be in two seperate updatepanels....

we are testing the Razor webgrid with Ajax. Works absolutely fine in IE8 when sorting in paging. However in IE7, any attempt to sort or page causes the grid to vanish from the page, leaving a blank space. The HTML that should be there, isn't!Has anyone come across this issue? How could we debug it? Page code below:

Here is my setup: I have an asp.net button on a page --
<asp:Button id="btnSelectEmp" runat="server" Text="Select Employee" />
I have a .js file with the following jQuery click event --
$("input[id$='_btnSelectEmp']").click(function ($e) {
$("div[id$='_divEmpSearch']").css("display", "inline");
$e.preventDefault();
});
As you can see, clicking upon the button will set a div visible. Nothing special; not rocket science. The div is wrapped with an asp.net update panel, and it contains an asp.net user control (.ascx)
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="divEmpSearch" runat="server" style="display: none;">[code]....
The button in the user control that does a postback is working great. I click it, a postback occurs and my div control is re-hidden. I can then click on the Select Employee button (the one that I supplied the code for at the very first of the question) and the jQuery click event is handled and the div will be reshown.However, the button in the user control that does an asynchronous postback works also, but after it hides the div, if I then click on the Select Employee button the jQuery click event will not be handled.What this tells me is that for some reason during an asynchronous postback to the page, something happens to the Select Employee button so that the jQuery click event no longer happens. Why?
I want to do the following:
routes.MapRoute("testwithoutcontroller", "Overview/Index/{year}", new {year = 2010});
But it fails when I call Overview/Index/2010 and gives me this error:
The RouteData must contain an item named 'controller' with a non-empty string value.
What must I do in order to only have Overview/Index be possible for my route?

I am running Visual Studio 2008 Version 9.0.30720.1. I created a Web App with a FromView and in IE7 it works great. My company pushed an upgrade to IE8 and all of a sudden when I run my Web App to test it, the formview completely dissapears. I tried running IE8 in Compalability View but it still does not work.
