In javascript I have an image which I set the .src at runtime in javascript. The .src points to a asp.net page with a few values as querystring parameteres that I want t capture on the server. this page has empty content. In code behind in the page load I need to generate the smallest image possible and return it as the response. how do I generate a small image and return it in the response?
I am using dynamic data entities linq to sql project. For my test project I have one table, with 10 columns and a single primary key for example. Almost all the columns are varchars.I can get the basic project up and running fine - update, delete, insert etc.ince it has no foreign keys, there are no search filters rendered. I was wondering if there was an easy way to generate a set of filters for the columns for this table. So a First name and last name search box. Is there a way to generate these filters for chosen columns and is there a way to generate these for all the columns
for example, above each of the columns in the grid there might be a text box ( I am not too fussed where the text boxes are rendered as such). Each of the text boxes will act as a filter for that column (doing a SQL 'like')
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I am using it in Gridview's EditTemplate Field to show color with ajax 3.5
In my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50); After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus. Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
and it was working well even After I upgraded my wevbsite to .net version 4 but when I started a new website from scratch in vs2010 using .net4 when I use ajax toolkit in this new site it is registered as folowing
and when I run the page I get the error The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>) I don't Know what is the reason for this. I noticed another thing. in my old website I was using thckbox script by using the files common.js, jquery-1.3.2.js,jquery.thickbox.js and puting them in a Javascript folder ad then registering them in Script manager as following
this was working well also but in my new site the jquery file version was jquery-1.4.1.js but also I added the old version f the javascripts files in the built in Scripts folder that is created by default b the new site and followed the same way in registering them in the script managerchange the JavaScript folder to the built in folder Scripts
but this doesn't work also in the new site I think that there is something diffirent in the 2 case which leads to this change in performance I wish your support and advice about how to solve this matter
What am I missing here; this should be straight forward, but when I attempt to access the "get_activeTabIndex()" method on my Tab Container's ID, I get the following error: "Object doesn't support this property or method"
This is using VS.NET 2010 with the AJAX Control Toolkit built for Framework 4, but I don't think anything was deprecated so this should not be an issue. I extract the ID of the control using serverside script variables, then attempt to access the method, but it fails. Take a look: [Code]....
Value 'tabCtrl' does indeed have value, as I can see it registers as an object (not NULL or Nothing) and ClientID resolves to the following: ctl00$ContentPlaceHolderMyApp$AJAXTabContainerNumData
I have done my searching and haven't found anything related to my issue. I have an aspx page that contains a regular drop down control. When the selectedIndex is changed, it fires off a post back and also rebinds a datalist based on its value. Inside the datalist I have an ascx control which has a gridview and an object datasource:
ASPX page:
[Code]....
My problem is that after my drop down posts back, when the process gets to DataList1.databind (in the selected index changed) i get a "The ObjectDataSource control 'ObjectDataSource1b' does not have a naming container. Ensure that the control is added to the page before calling DataBind." error.
During the post back, the pageload on my control runs and all my properties seem to have its values.
I am using FireFox v3.6.14 I am developing on VS2010 and have a project with a web and Silverlight solution.try to run the project I get the above error.I cant work out if its Visual studio error or a firefox error, Im pritty sure its not my code!!Ive tried running the same app via Chrome with a similer error.
My asp.net page dynamically displays 207 questions (I can't control this). Each question have 10 validators. When ASP renders the page it creates following three lines for each validator:
Althrough these three lines are just 4kb you can imagine that 4*10*207 is quite a lot. How can I mark all validators as dynamic and set evaluationfunction to same value without asp generating the line for me?
i have installed ajaxtoolkit 3.5 but when i debug i am getting this error Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' even i have changed my tags to
I am trying to write a bit of code that will export the current contents of a gridview to an excel file on the local system. I've looked at several examples on how to do it and implemented it. However, i am unable to get the gridview to export the data.
Here's the basics of what i am doing:
I'm using httpcontext.current.response to specify the file contents and filename. creating Stringwriter and htmltextwriter objects.
then rendering the table into the htmlwriter then rendering the htmlwriter to the response.
however, regardless of how large or small the table i am working with is, i keep getting the following error:
[Code]....
Visual Studio opens a file called ScriptResource.axd and the error is noted in the following section of code at the throw error line.

I have included the Public Overrides Sub VerifyRenderingInServerForm(ByVal ctl As Control) method as suggested by others but this has not resolved my issue. I am not sure how to proceed.
I am dynamically generating script code to return transaction data to Google Analytics using their ecommerce script. The code that generates the script is fully tested and functional on my development machine and when I view the page code the script, along with any values that were passed to it, can be seen above the </form> tag. Happy days, or so I thought. For some reason the code is not being generated when I test it in a live, hosted environment. I cant figure out why this is the case as the code is quite simple. I simply generate the script code and register it on the client side (see code below)
//Capture the transaction data for analytics ecommerce tracking //Generate the necessary script code string strAnalyticsEcommerceScript = Analytics_Ecommerce_Script_Creator(); //Register the script on the page Page.ClientScript.RegisterStartupScript(this.GetType(), "AnalyticsScript", strAnalyticsEcommerceScript);
The page in question is called "Order-Successfull" and is where customers are sent to when they have succesfully payed for an order. On this page:
-The order is added to the orders database table - The customer is emailed an order confirmation email - The google analytics script is generated and registered
The Sequence is as follows:
[Code]....
Whats really interesting is that if I move the Analytics script creator code before the code that sends the emails, the script is generated and can be seen when I view the page code. If I do this, however, the emails do not get sent. If I lay the code out as per the code I have inserted in this post, the emails get sent but the script code is not placed on the page.. The code to that actually sends the emails is quite standard:
I have a Gridview that I am using in a User Control. The grid loads great and my paging buttons that exist outside of the grid itself work properly. When I click my delete button inside the grid, I am getting an invalid postback message. How should I handle this? My control raises one event by the way.
I have set of 10 tabs on my web form. When a new tab load it post back the data of the existing tab as its the need of the system. Now each time a the new tab load there is a flicker and tab positions change. Is there a way to arrange them just like windows tabs so that they all are in one container and get justified everytime i click the new tab.
So, I've digged the internet in seach on a decent tutorial on howtta use the ReorderList control that comes in the Ajax Tookit. I've made lists that can reorder and such, the problem comes when I wanna include an edit feature. There's almost no documentation on how to do this.
I used the AjaxToolkit AutoComplete today. It works fine. But what I hate is that I have to use the "CompletionSetCount" at 5 or 6 only so it doesn't reach the following textbox on my form.
The problem is that the dropdownlist of the AutoComplexeExtender gets under my textboxes, so it hides some items of the list.
When I try to play with the z-order of the "CompletionListCssClass" or "CompletionListItemCssClass", then the list appearance is all messed up
