Problems refreshing DataGridView (bound to a BindingList)

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :.NET Framework


I have bound a DataGridView to a BindingList<MyEntity>. MyEntity has some properties that affect other property values. Let's say, because it's true, it has a DisplayCurrency property that controls what currency is returned in various Amount properties. I show a list of available currencies, and when the selected currency changes I do something like this:

var list = (BindingList<MyEntity>)grid.DataSource;

foreach (var entity in list)

 entity.DisplayCurrency = selectedDisplayCurrency;


AFAIU, ResetBindings() is a way for me to notify the binding list that I've modified its content, and the list will then in turn notify the gridview by firing off an event. And it works fine; all the amounts in the grid are updated.

It's all very wonderful, except for the fact that it seems to behave as if I had removed the datasource and re-assigned it...

  • I lose the sort state
  • It scrolls to the top
  • I lose the selected item
  • ...

So I guess my question is: Is there any way I can get the DataGridView to just reflect the changed values

Dynamic Textbox List Control - problems refreshing


Ive been stuck on this one for a month:

So I have a custom control that has a list of textboxes, and a button that will dynamically add a new textbox to the list.

 So I have an addTextbox() function, that will do something like

TextbBox t = new TextBox()

 then I add it to the page.  So adding a new textbox works fine, but I have values that I want to put into each textbox and upon each page load, the values get replaced.  What I need to do is get the textboxes from the viewstate so I can use their values for other textboxes, but since they are created anonymously, im not sure how I can do that.  I tried to get the unique name and put all of them into an arraylist, then upon the next page load, load the names from the list, but the unique name isnt unique.  Thanks

Problems refreshing parent page



I have a parent page which open a client page with window.open. In this client page I add a data entry. After that I want to refresh the parent page because there is ja list of entrys int the master page. This is the code:

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "RefreshParent", ";window.opener.document.forms(0).submit();", true);

The parent page refreshes but only the content and not the master. My data list is in an updatepanel of the master page.

DataTable Bound to DatagridView DataRowState.Modified not getting change on first row


Updating the first record listed in my DataGridView that is bound to my DataTable . When I run Save process I run through this line of code to get all records that have been modified:


If I have changed the first record in my DataGridView my modifiedRows DataTable is Null. If I change any of the following records they are in my modifiedRows DataTable .
I have tried changing other records in my DataGridView first and then changing the first record then running the Save process and still....other records are there and the first record is not.....

Also....I checked the unitDataDT and it has the change. I sorted the datagridview to try and update a different record and it still did not add the change to the modifiedRows Datatable....so it seems to not work for the first record listed in the DataGridView.

Any ideas?

Top .NET Performance Problems and how to avoid them

Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

AutoCompleteStringCollection for text box in DataGridView 2.0

I have been searching for a way to have autocomplete in a DataGridTextBox
object. There does not appear to be an obvious way to do this like you would
for a TextBox outside of a grid using the AutoCompleteCustomSource. Any
thoughts on how I can add this collection? :)

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?

Visual Studio 2008 Memory problems


My memory in task manager reaches about 900,000K  and I don't know why it does this. Definately slows everything down, especially when I rebuild my tableAdapters, takes about 30 seconds sometimes to rebuild the project.

Problems with Forms Authentication in DD 4 site


Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

     <authentication mode="Forms">
            <forms name=".Star" loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Default.aspx" path="/" timeout="43200" cookieless="UseCookies" />     

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!

Problems posting to a package


Hey Y'all

I'm currently creating a program that accesses a mysql package to add data to a few tables.  I'm currently getting an error that says  "

ORA-01403: no data found
ORA-06512: at "JESSE.PKG_WORKPLAN", line 42
ORA-06512: at "JESSE.PKG_WORKPLAN", line 177
ORA-06512: at line 1


These lines are


and 177:add_team_members(V_PROJECT_ID, V_START_DATE, v_FISC_YEAR, V_MEMBERS ,V_NUM_MEMBERS,'add');

Checking these variables in my asp.net page they are all receiving parameters.

Is there a  way to see what the database is actually receiving from the asp.net page?

Or is there another thing to be looking at?


URL Routing and Existing HttpHandler problems


Hello everyone,

I have a problem:

I am currently using 2 features: 

1. HttpHandler

Registering the path="res.aspx" verb="*"

2. URL Routing:

Registering with this pattern: "Company/Edit/{*companyId}","~/CompanyEdit.aspx"

In my CompanyEdit.aspx page, I used httphandler res.aspx to generate some images at client.

  • res.aspx?img=1
  • res.aspx?img=3

Now the problem is here, the page is load success with companyId = "12345", but when the images was loaded at client, it loaded the CompanyEdit.aspx again and show error with wrong id.  

I have debug and find the problem that because when image's urls were generated to client with url=res.aspx?img=1, url=res.aspx?img=3, the asp.net will understand that they are Company/Edit/res.aspx?img=1, Company/Edit/res.aspx?img=3 when it maps with URL Routing pattern.

=> So the CompanyEdit.aspx was load again with wrong id (id now is "res.aspx"). 

So, do you have any ideas to solve this problem, or other design.

Thanks, and best regard

ASP.NET 4 precompilation problems



We used ASP.NET precompilation (first manually, then with VS2008 WDP) with .NET 3.5 almost (see below) successfully.

After we moved to 4.0, the precompilation no longer works properly. The precompilation process itself succeeds, and the website works, but it consumes about twice the CPU it does without any precompilation. We use non-updatable precompilation (so webpages get compiled completely).

Our internal profiling tells us that most of the threads spend their time within variations of the following stack:


  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultFromCacheInternal(System.Web.VirtualPath virtualPath, bool ensureIsUpToDate) + 0xa2 bytes 
  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0x5b bytes 
  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(System.Web.HttpContext context, System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0xcb bytes 

Problems converting VS 2003 project to VS 2008



I'm having problems converting a VS 2003 project to VS 2008 (tried 2005 as well, same problem). There are several problems;
a) I don't have VS 2003 installed.
b) The project is a web service, however I'm not sure what type of VS project it was created as.
c) The general knowledge about the project setup is..slim.

I get a error message using the conversion wizard, however, I'm not familiar with the tool and I cannot quite find any good information on Google for it, so I am left with a error message I do not understand.

Conversion Issues - myProject.csproj:
Unable to open the Web site 'C:\local\path\to\project\myProject.csproj'. The Web site 'C:\local\path\to\project\myProject.csproj' does not exist.

The web service is not intended to run on the dev machine, it is copied to a test or a prod server. However, I do not know how this was done previously. I'm thinking that in order to convert, it has to access the server on which it should run (which is set somehow in a config maybe). But that doesn't actually make any sence..

If anyone could shed light on this, I would really appreciate it.

Thank you.
