I have an ajaxified ASP.NET GridView which dynamically populates the data on the dropdown change event. We use JQUERY and JASON on the page. When ever the trigger the dropdown change event the data changes. I have few check box columns in the Grid view and based on the checkbox checks I need to make some changes in the database.

But the value I get from the gridview  is always the value which is set during the default dropdown selection on the page load.

How can I make sure I can retrieve the exact value I see in the page based on the dropdown selection?.

FYI it's an ajax page and all the changes are designed in the client side. 

Could someone help:

     I am thinking about using the Ajax Control toolkit tabs control but I will need to add some CSS to improve the look of the tabs.  I found (what I thought) would be the answer I was looking for with the following link http://mattberseth.com/blog/2008/04/ajaxcontroltoolkit_tabcontaine.html.  After checking it out I found that every link was dead and every piece of information that I found seemed to be outdated or lead back to this guy's blogs.

     My question is this.  Is the (Ajax Control Toolkit) Tab control out dated and not well supported anymore?  If not would anyone have any themes for the control.  I have looked at using the JQuery Tab control but the Ajax toolkit looks really nice and would be perfect if I could get a theme for it.

Any help / suggestions would be appreciated.

Thanks

Hi,

I am Upgrading my project from VS2010 to VS2013.

I am calling Ajax methods from Javascript. By using [Ajax.AjaxMethod()] in .cs page.

In 2010 its working fine.

But in 2013 its giving errors as below 

Failed to load resource: the server responded with a status of 404           ajax/common.ashx not found.

But in our Application ajax folder it self not there.

In Web.config we added below code

<location path="Ajax" inheritInChildApplications="false"><system.web><httpHandlers><remove verb="*" path="*.asmx" /><add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" /></httpHandlers></system.web><system.webServer><handlers><remove name="Ajax" /><add name="Ajax" verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" /></handlers></system.webServer></location>

Even though I am getting same error. 

Then i tried to replace the dll's with latest .net 4.5 ajaxtoolkit Dll's, Tried installing AjaxToolkit via Nuget... Still no luck.

All Ajax methods are not working.

Please help me.

Thanks,

Shivanag.

HI,

How to set ajaxcontroltoolkit linechart chart area colors and y axis start value and difference of y axis values.Let say Y axis vlues are like 5,10,15,20 then i need set  0-5 chartarea background color. 

I have a radio button that has Async Postback.

When you click rbTomorrow radiobutton the async postback doesn't work in chrome

The functionality works in Safari, Firefox and IE. but the Async Postback doesn't work in chrome (production).  In my development environment the Async Postback works in Chrome but on production server it doesn't work.  I have hosting through godaddy.

Web.config is the same in development environment and production except for the connection strings.

It might have something to do with the radiobuttons being in an updatepanel but any advice is appreciated. 

Here is the html markup below .aspx. Thanks!

Hi,

I have done Multiple select autocomplete with like tagging. After save the Values in DB. I want to bind it back in "div.ui-autocomplete-multiselect-item"
After saved i am getting a values what ever i saved. that should bind here.

Any idea suggestion. 

I have a multivariable multiple class json coming as a result.  From [WebMethod} I have this string returning (certain it is correct):

[{"id":"0","date":"3/4/2001","name":"John Doe","title":"IT"},{"id":"1","date":"3/4/2001","name":"Jane Doe","title":"Homemaker"}]

etc

I want TextBox4 to print the json string.

Right now it just prints out the Error Code:

Error Code: Status: [object Object] Ex: error

How can I correct that?

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script><script type="text/javascript">$(document).ready(function () {$("#<%= Button1.ClientID %>").click(function () {
                var mo1 = $("#<%= TextBox1.ClientID %>").val();
                var dy1 = $("#<%= TextBox2.ClientID %>").val();
                var yr1 = $("#<%= TextBox3.ClientID %>").val();
                var data = { mo:mo1, dy:dy1, yr:yr1 };
                var json1 = JSON.stringify(data);$.ajax

I am converting an Access database to an ASP web page.  One field contains a list of people. I want the dropdown to only contain certain people, but there is already allot of names that are not those certain people.  I want to allow the old data to stay in the database, but any new ones, or if they edit and change the current name, I want it to have to be in the list, but if they don't change it the name, I don't want it to throw an error.

   I have my SelectedValue='<%#bind("RequestedBy")%>'.  

If the data in the database is in the list, it works fine.

If the data in the field is not in the list, I get an error, because combobox has a selectedvalue which is invalid because it does not exist in the list of items.

How do I just ignore it if the name isn't in the list? I want the name to stay in the box, even if its not in the list. Only if I try to change it, do I want to have to choose from an item in the list.

I have a simple formview that binds to a SQL database. This formview is used for adding new records only since its default view is Insert. For simplicity I put one label and one bound textbox inside the insert item template. All works fine. However, if I put an update panel inside the formview's insert item template the formview's update method fails becuase of a null value. If I look at the text property of my bound textbox right before the update I can see the value just added. So it appears the control has the value but it's almost as if the data binding has been broken. Of course if I remove the update panel everything works fine. If I put the entire formview inside an update panel it works fine, too. But since I will want to trigger my update panel off a particular control inside the insert item template, the update panel must be inside the template. I've seen a few similar posts on the net but no answers. Is this at all possible???

I have placed a databound textbox within an UpdatePanel.  The UpdatePanel is embedded in a formview.

When the formview is edited and saved, in the formview ItemUpdating event, the field bound to the textbox e.NewValues("FieldName") is nothing and a blank value is saved in the database.  However, if I take the textbox out of the UpdatePanel, the field bound to the textbox e.NewValues("FieldName") maintains its value and updates the database correctly.

Is there a fix for this problem?

Here is my sample code:

Thank you.

Hi All,

We have issue with image loading while using AJAX

- We are using UpdatePanel to validate the request.

Issue:

On page load below code is working fine.

imgVefrification.ImageUrl = "ImageValidate.aspx";

On button click after validating the image value, if validation fails we are trying to call it again.

But image is not getting refreshed (Debug is not hit/process "ImageValidate.aspx" page)

Please suggest.
