Forms Data Controls :: GridView1_RowDataBound - Not Firing / Upgrade To DOTNET V4 With Appropriate AJAX Dll's
Jun 24, 2010
My aspx page contains "OnRowDataBound="GridView1_RowDataBound"" call, which I'm trying to call when I move my mouseover a databound row. Thus changing the background colour of the row.
When I move my mouse over the row it seems to bypass the OnRowDataBound call and proceed directly to the "mouseover" function which proceeds to error as the "(row.style.background == row.basecolor)" is undefined.
This has previously worked under older versions of AJAX and DOTNET. I've upgraded to DOTNET v4 with appropriate AJAX dll's.
I built a page with a cascading dropdown extension tied to a db, (and another one to xlm source), which was working fine. then I tried to update my ajaxcontroltoolkit.dll becuase I had an old version, then the sudden the all the data in the dropdown lists is lost.
I have two questions, could anybody please answer to those:1) Do I need to install Dotnet framework 2.0 if dotnet framework 3.5 is already installed on the same server?2) Also do I need to install "ASP.NET 2.0 AJAX Extensions 1.0" if higher version is installed on the same server?
I upgraded my site to works with Microsoft Visual Web Developer 2010 Express, works with .net 4.0 and new ajax tools. My site is manage on our site . Now it work on win server 2003 sp2 frameworks 2.0 ajax ast.net 2.0
Is the new upgrade site will work on the web sever ?Should I Upgrade the server to framework 4.0 ?
We upgraded our project to 4.0 yesterday and did a live release. Unfortunately for some reason on one of our pages the tab container does not display anymore. I've set a breakpoint at the end of code execution and the .Visible property of the container is True, but the generated HTML has a CSS tag set to make it invisible:
If I use the IE8 development tools to remove the style property then everything displays correctly. why the container is set to be invisible even though the code behind is setting it to visible?
An Ajax Toolkit SlideShow used to work in .NET 2.0. After being upgraded to 3.5 the same slideshow stops working as before. It always pops up "Object reference not set to an instance of an object.". Different rewrites cause different errors at embedded Jscript level that cannot be fixed. I have added the AjaxToolkit.dll 3.5 under bin folder and placed its items in the VS2008 toolkit.
I upgraded today to AjaxToolkit version 3.5.40412.2 and as soon as I did my TabContainers stopped displaying ina browser. They look fine in design view and I do not get any errors.Has anyone seen this or know if there is a post already addressing this?
I just upgraded a project which was working fine using some ajax control toolkit components. When upgrading the project from VS2008 to VS2010 now I get an error stating that the 'ToolScriptManager is no a known element'...?My ajaxcontroltoolkit.dll is in the bin folder of the website (as it was before) but that doesn't seem to satisfy the VS2010...
The exact error is:
'ToolScriptManager is not a known element. This can occur if there is a compilation error in the website or the web.config file is missing.
In the build errors I have this error:
Error 17 Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. C:ProjectsmedlemsportalumbracoMembersEnrolment.aspx 10
Does anyone know what should be done to resolve this...?
I'm trying to upgrade a website to the new Release of AjaxControl Toolkit but I have some problems. If I modify the reference to the library I recibe an error because the new realese use an other version of System.Web.Extensions (3.5.0.0), I add a new reference to this new version of System.Web.Extensions and delete the old version but I still having errors.
In my website I have a WebService. I'm using Visual Studio 2005 (Framework 2.0) and this is my Web.config:
I have an update panel with content that needs to be updated by a listview item which is a linkbutton, in .NET 3.5 I just used the defaults on all the controls and everything worked fine, after the upgrade to 4.0 the linkbutton causes a full postback with page refresh. I did try setting the linkbutton's id as the trigger for the update panel and still causes same page refresh. The scriptmanager is on the masterpage with enablepartialrendering = true.
I upgrade to VS2010 and I no longer sees the UpdatePanel control available. I do have the latest AJAX Control Toolkit but I do not see this option. In addition, I kept getting the above error. How do I resolve this issue?
I have a dropdownlist column in gridview, which is databound.when I select from list, I want to set another check box columnin gridview to true.But GridView_RowEditing event is not fired ..Code is given below.
I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box
controls.Once the datagrid binds then the events in the aspx page not firing.Issue occured when the number of rows greater than 500.The number of rows less then its works fine.
I've put a simple gridview on my Asp.net webpage. I've configured the fields via C# code:
gvMainDataGrid.AutoGenerateColumns = false; gvMainDataGrid.AutoGenerateDeleteButton = false; BoundField bfldSeqNmbr = new BoundField(); bfldSeqNmbr.DataField = "PKSequenceNmbr"; bfldSeqNmbr.Visible = false; gvMainDataGrid.Columns.Add(bfldSeqNmbr); BoundField bfldEmployeeCode = new BoundField(); bfldEmployeeCode.DataField = "Employee Code"; bfldEmployeeCode.HeaderText = "Employee Code"; gvMainDataGrid.Columns.Add(bfldEmployeeCode); BoundField bfldProjectCode = new BoundField(); bfldProjectCode.DataField = "Project Code"; bfldProjectCode.HeaderText = "Project Code"; gvMainDataGrid.Columns.Add(bfldProjectCode); BoundField bfldProcessCode = new BoundField(); bfldProcessCode.DataField = "Process Code"; bfldProcessCode.HeaderText = "Process Code"; gvMainDataGrid.Columns.Add(bfldProcessCode); BoundField bfldActivityDate = new BoundField(); bfldActivityDate.DataField = "Date"; bfldActivityDate.HeaderText = "Date"; gvMainDataGrid.Columns.Add(bfldActivityDate); BoundField bfldActivityHours = new BoundField(); bfldActivityHours.DataField = "Activity Hours"; bfldActivityHours.HeaderText = "Activity Hours"; gvMainDataGrid.Columns.Add(bfldActivityHours); CommandField cfldDeleteButton = new CommandField(); cfldDeleteButton.ShowDeleteButton = true; gvMainDataGrid.Columns.Add(cfldDeleteButton); It's data source is a Dataset retrieved from a webservice. Here is the C#code to bind the data to the gridview Service1 MyService = new Service1(); dsMainData = MyService.GetData(strIdNumber); gvMainDataGrid.DataSource = dsMainData; gvMainDataGrid.DataBind();
It retrieves great. No problems at all. Then, when I actually try to use the delete button, I get an error that the RowDeleting event is not being handled. I thought that was pretty explicit, so I created the event:
