AJAX :: Control Toolkit's Combobox + Internet Explorer Are Too Slow?
Feb 21, 2011
I have problems with optimizing AJAX Control Toolkit. The specific problem is that 4800 records take about 30 seconds to bind in Internet Explorer (only 2 seconds in Opera & Firefox). I've tried anything, but I still can't improve the load time in IE.I've already enabled compression and caching, I'm using ToolkitScriptManager instead of ScriptManager. I've tried setting LoadScriptsBeforeUI and EnablePartialRendering to false, but it still doesn't help.
I made a login system, when the user presses the login button a pop up panel using ajax appears. The textboxes and other features are in a Web User Control.
The problem is that when writing information in the textboxes in IE or pressing the cancel button it is very slow compared to other browsers. I have the latest version of Ajax.
I got the following datalist populated with 12 images a page average size is 75kb.If i move the scrollbar in internet explorer up and down it goes very laggy and stuttering, while firefox has noproblem at al fast and smooth. If i remove the images there is noproblem. if i disable the setting smooth scrolling in ie it's a little better but still not good enough. I can't seem to find a way to get this right is there some kind of script or am i doing something wrong. Or maby do i have to put the datalist in a user control?
I'm new in using C# in ASP.net My code is causing Internet Explorer to run slow and return error message asking to stop running this script.
When I use the "Select *...", it return about 700 rows of records and it cause the error.
When I use another SQL "Select NOC0854....", filtering some records, it return about 300 rows of records and no error message appear.
How I can improve my code so that I can retrieve all records from my table? I think 700 rows of records doesn't seem a lot, maybe my code is not correct?
Code: //cmd.CommandText = "Select * from PTH3759"; cmd.CommandText = "SELECT NOC0854 from PTH3759 WHERE HID0019 >= TO_DATE('11/01/2014','MM/DD/YYYY') AND HID0019 <= TO_DATE('11/28/2014','MM/DD/YYYY')"; cmd.CommandType = CommandType.Text; OracleDataReader dr = cmd.ExecuteReader(); if (dr.HasRows) { GridView1.DataSource = cmd.ExecuteReader(); GridView1.DataBind(); }
I just downloaded the latest ajax control toolkit and was trying to use ComboBox (as described on the samples page). However, I can't find it (tried to do reflection on the assembly as well).So is the ComboBox still in ajax control toolkit or it is removed or renamed etc?
I am using Tabcontainer of AJAX Control Toolkit . The problem is that, i have 15 tabpanels. this tabs in three lines, first 5 in one line, second 5 tabs in second line,third 5 tabs in third line.
If I click first / six/fifteen'th tab means it shows the relevant tabpanel with data correctly.
Each tabs have three buttons like Save, Edit and Cancel
All three line's tabpanels works properly in Chrome and Firefox.
But in IE,
First line tabpanel's button work properly...
second and third line tabpanel's buttons is not work properly,
if I click the second and third line tabpanel's buttons means.. It didn't go to page load..
ajaxcontrol toolkit combobox control, a picture is worth than a lot of words so here is the picif you are not able to view then here is the link

the problem is the items text in the combox box is having a square beneath at the second character which is hindering the visibility of the list. but the square is not appearing in the text area.
I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....
Combobox markup below
<asp:ComboBox ID="ProductDescription" runat="server" [code]...Answer in vb preferably.
I have a ajax combobox in my page, when i try to select an item from it i can select by typing in text and its selectedindexchanged event fires, but when that event is complete and when i try to select another item from the combobox it produces the following error:
could not complete operation due to error 800a025e,and an alert asks me if i want to debug it.If I press yes then i get this page:
I'm trying to use the Calendar control in a local intranet enviroment, so I need to put all the Javascript files locally, I've downloaded the Ajax Control Toolkit 40412 source code and extracted the Scripts from
"..AjaxControlToolkit_9c860ac12ae9SampleWebSitesAjaxClientWebSiteScripts",so I write the following code
I currently have an Instance of the ASP.net ajax control toolkit combo box residing in a field set with a style of position:releative applied. The control also sits in a very plain table.
There are two problems with the display of the list:
The list does not sit flush with the text box. In I.E. 7 (which is the majority of my target audience, intranet where IE7 is the company standard) the list display about 10px below the fieldset, which is what the bottom margin of the fieldset is set to. In FF 2.0 the list sits sinificantly lower and off-set to the right.
Below the filed set there is more content in a div, also with a style of position:relative applied. The list from the combo box displays behind the content of this div, which is obviously an issue.
Removing position: releative from the fieldset resolves the display issue of the combo box, but results in other unwanted display side effects.
I have a situation where I need to have close to 30 drop down lists on one form. The user also wants the autocomplete functionality. I decided to use the ASP.NET AJAX control. So that the page will load faster I hide them until they are needed. But, as more and more become visible the postback time is getting longer and longer.
I know this can be fixed, but I'm not sure how. Can anyone give me any advice, point me to some articles? Do you have a suggestion for another method of doing what I need? Maybe, I shouldn't even be using ComboBoxes for this?
I have one ocx control. this ocx for getting information about keyboard events from client machine.I need to access this OCX from web page IE. this ocx should install in client machine.
When VS debugging view on the .aspx page on Internet Explorer 8, I don't see the picture except for a blank Image control box outline and at the top left corner, a symbol "X" in a square box was displayed. Is there some settings to do with IE8 or Visual Studio 2008 ?
I am creating an accordion dynamically through aspx.cs file. There is a subaccordion inside each accordion pane. I am seeing that if there are 10 or more accordion panes in the root accordion, then I can only expand first 4 or 5 panes. Nothing happens when I click on other panes. This is happening in IE8, tried on three different machines. I don't see this problem with Mozilla, it can open as many panes as possible, I have tried with 20 panes in mozilla.
Some of my customers using Internet Explorer can't use my website because the call to my .net webservice failed. Under FF and Chrome no problem. For most of my customer using IE, it's working fine also but not for all...
I have isolated a call to the webservice that failed
[Code]....
I can't find why it's not always working with IE. I'm not able to get the error on my computer (even by changing security, privacy settings in IE).
when i test this page http://www.catalogues4u.com.au/ViewCategory.aspx?catID=119 im getting the above error. to replicate this issue visit the above page in ie7 and you will get the prompt.
I have a combobox inside a hidden div which I use css display = none to make it invisible, but when I make the div visible by setting display = block, the combobox just show the input and its button and ul list all have css as display = 'none', visibility ='hidden'.
I can tell it is done by combobox inbuild javascript because I tried to use javascript to set the css manually with no luck. It is a bug of combobox. I spent a week to solve this, and our team put a lot trust on the toolkit.
Below is the code to reproduce the bug. When you run it, you can't see the dropdown:
I have just put a site on a production server for testing.However,the submenu is not visible in internet explorer but is on mozilla.The submenu is visible when run from the local host.
