I have a drop down list that hides a panel with a bunch of controls when a certain value is selected, and shows the panel again when some other value is selected. This works fine. However it's slow when running both on my local webserver and on my web host, and takes about 1-2 seconds. What could be the reason for this? The only thing I do is to check which value is selected and hides/shows the panel.

Searching on google, i deffinitly can't find a non-javascript way to show and hide my panel/updatepanel.I do have panels and updatepanels, I want to show/hide them on the fly, after a button click, preferably without javascript, or if so, with jQuery.All the examples I found consumes a lot of code and honestly I don't want to crap out my code just because of this.
View 2 RepliesI'm trying to hide all panels on a page, when a button click occurs.
This is on a web content form, within a master page.
The contentplageholder is named: MainContent
So I have:
foreach (Control c in Page.Form.FindControl("MainContent").Controls) {
if (c is Panel) {
c.Visible = false;
}
}
This never find any panels. The panels are within an Update Panel, and I tried
foreach(Control c in updatePanel.Controls) { }
and this didn't work either. I also tried :
foreach(Control c in Page.Controls) { }
and that didn't work either.
I have a web application which has several update panel this page is taking around 2 miniutes to process. Is it a problem with the IE 7
View 4 RepliesI have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
View 2 RepliesI need to show/hide a table-row upon the click of a linkbutton. I have gotten it to show the row when clicked, but instantly reverts back to being hidden. I have tried putting the CSS style display attribute in a numerous amount of ways and it is still not working.
This is my .aspx file:
[Code]....
This is the .js file that is properly imported:
[Code]....
When loading the page I have tried a numerous amount of ways to set the attribute to none, in the stylesheet, in the style attribute of the tag on the .aspx file, via a similar javascript function that hides the element. All of these show the same result, when clicking the button it simply reloads into being hidden after being changed.

For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.

View 4 RepliesI was using the code below to query the database and to show or hide content if the result was true of false. I use two panels so I can dispaly the right content block depending on EVAL
<asp:Panel
ID="Panel1"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(false) %>'>
<asp:Panel
ID="Panel2"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(true) %>'>
This was working with a CSS layout but I had to place all the content in a table and now it does not work. Is there another way to do it
Why the ajax control is working slow when i upload to the server? such as the custom validator is slow response in the server, the modal popup box or loading is slow to response or close up after click the ok button. It work fast in the local server.
View 2 RepliesIn my website, I have a TreeView that has this structure:
Root
|-Leaf
|-Parent
|--Leaf
|--Leaf
|--Child
|---Leaf
|---Leaf
|--Child
|---Leaf
|---Leaf
Is it possible to make the tree in a "collapsed" state where all the Leaf nodes and ONLY leaf nodes are hidden from view until its parent node is expanded? The ideal solution would be to do this without a postback, but any solution at this time would be helpful. The "collapsed" view would look like this:
Root
|-Parent
|--Child
|--Child
Expanding the Root, Parent or Child nodes should show their Leaf nodes. Collapsing the node should re-hide its leaf nodes, but leave the child nodes visible.
I have an image button on my gridview in one column, and in the next column, I have a nested gridview. What I am looking to do, is to use my image button as a way to show and hide my nested gridview. I do not want to use JavaScript, because my page already uses a great deal of JavaScript. Therefore, I want to use code behind on the button, this is what I have done so far:
ImageButton b = (Button)sender;
GridViewRow row = (GridViewRow)b.NamingContainer;
if (row != null) {
int rowIndex = row.RowIndex;
How do I use my selected row index to call the nested gridview to be visible and not visible?
Here is jquery code which hides my table cells with the ID of .style2:
$('#myRadioButtonList').change(function() {
if ($(this).attr('checked') == true && $(this).val() == "HB") {
$('.style2').hide("slow");
};
});
and here is my radiobuttonlist
<asp:RadioButtonList ID="myRadioButtonList" runat="server">
<asp:ListItem Selected="True" Value="HB">None</asp:ListItem>
<asp:ListItem Value="HOBSKS">Service </asp:ListItem>
<asp:ListItem Value="OBAKS">Open Service</asp:ListItem>
<asp:ListItem Value="BBKS">Close Service</asp:ListItem>
</asp:RadioButtonList>
I am inspired by this topic

This way my jquery is not working, there are mistakes in the part
if ($(this).attr('checked') == true && $(this).val() == "HB")
I tried those two conditions above alone, and they both are not working. I need to reach to my radiobuttons but seems like I can't. Then how should I write that part in order to make my code work.
I'm trying to implement AJAX within an existing application and it seems to be running slow.
I have 3 datallist that all have checkboxs. I have buttons that all users to check all checkbox for a specific datalist. I have an update panel around each datalist. When I check and uncheck it seems to be really slow. I also have 3 textboxes and 4
buttons within my update panel.
When I user uses this site it hides and shows different panels and that seems to be really slow when the users press a button. There is no database stuff happening when the slowness occurs.
I have a download button on my website to download an application of mine. It works fine but I noticed people are clicking it repeatedly. The response time is a little slow after you click the button. Not that bad for me but maybe it's worse for some. In the button click sub I have the code to get the file and bring up the download window and I also have code to increment a table for download count and get the IP address of the person who clicked the button. If I just have the code necessary to do the download the download window comes up a little bit quicker. Here's my button click sub :
Code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
'
Dim FilePath As String = Server.MapPath("~/FolderForDownload/MyApplication.exe")
Dim myfile As New System.IO.FileInfo(FilePath)
If myfile.Exists Then
Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name)
[Code] ...
What I've noticed is that when I had Responcse.End() before my code to get the IP address and increment my table and save the IP Address it would skip performing that code so I moved it below the code. It performs the code but I noticed that after you click the button it takes longer before you see the window pop up that asks if you want to Run or Save.
I tried putting the code to get the IP address and increment my table in a separate sub and then call the sub after Response.End() but it still doesn't perform that code unless I call that sub before Response.End().
I'd like to do everything I'm now doing but get the Do you want to Run or Save window to open sooner. I'm getting a number of people downloading my application from overseas and perhaps when it runs the code to identify the IP address it takes longer. I'm not sure but I see people clicking the download button repeatedly. My table records the exact time to the second when they clicked the download button and to take an example, there are 4 consecutive entries with the same IP address and the times are 3:28 PM for all 4 with the seconds being, 13, 15, 16, and 17.
I put a test download page on my website. When I was running in Visual Studio and using a localhost address I was seeing a big difference in how quickly the window opens after you click the download button if there's download code only versus download code with the other code. When I copied the page to my website and accessed the webpage on the internet there didn't seem to be hardly any difference.
Here's a link to the test page on my website if you want to try it out. You don't have to download anything but you can see how quickly the window opens asking if you want to run or save. There are 2 buttons on the page. One says Download Code Only and the other Download Code and Other Code.

I just tried it out and I saw a big difference in time between the two but earlier I didn't. Sometimes I think the added code runs faster and other times slower.
I dont want them to be able to select a listitem until they click edit .
here is a picture of what it looks like now.
have a website with MasterPages, on load master page has many database roundtrips and logics implemented.Now, if move to one page to another, the MasterPage get reloaded and all the above mentioned procedures processed again, which again takes a lot of time and as a result my website's response is very slow.For eaxmple, once the default page is loaded, all the child pages can load within the centent area (in ajax style).
tell me some workaround to optimize the site so that it doesn't this procedures repetitively.
I was thinking about the performance when I use code to hide some control in aspx page using delimiters or in cs file. For e.g. If I have a panel and I want it to get shown following some condition, so I can achieve this by two ways
1: Using code in aspx file, something like this
<% if(isAllowed) { %>
<asp:Panel ...></asp:Panel>
<% } %>
2: In the code file, something like this
<asp:Panel ID="pnlMyPanel" Visible="false"></asp:Panel>
And in cs file
if(isAllowed)
pnlMyPanel.Visible=true;
In my view, first way should be good as it will not at all create any Panel in the page. Am I correct here?
I have a Listview in ASP.NET 3.5 page. When I press the Edit button it takes about 10 seconds before the screen is refreshed.

I'm using PopupControlExtender in a GridView, which pops up various dropdowns, treeviews, calendars etc. depending on which cell is clicked. I'm populating the dropdowns on the OnPreRender event. The result is, GridView is becoming extremely slow. I've tried removing Calendar controls, the Grid is still very slow. My guess is the enormously large source view of the page, resulting from populating controls on PreRender. Here is a sample ItemTemplate:
[Code]....
My goal is to populate the controls inside popup panel only when that panel becomes visible. I tried using OnResolveControlID event for this in PopupControlExtender. But strangely enough, that event fires only when control is NOT found, contrary to what its name suggests.
Anyway, my goal is to populate the popup panels controls (mainly ListControls) ONLY when their container panel becomes visible - hoping that this will make the grid faster. The same grid works perfect with AutoGenerateColumns=true and no populating of ListControls (not an option). Also, I'm NOT using debug option in web.config.
