• Toby Sharp Adding a new line in a richtextbox

  it just doesn't work, I went over all the code in this forum and none of them worked.

• armandino ListView AllowColumnReorder

  I would like to enable the AllowColumnReorder property in a ListView control, but cannot determine whether there is a way to do either of the following: 1.) Either disable moving certain columns or receive an event prior to column move to prevent it form being moved. (I would like to keep column 0 always as column 0) Would also like to have some control over where a column is moved to. 2.) Receive an event after the column is moved (with details on where it is moved), or be able to query/set the column order. I need this for 2 reasons - a.) I need to be able to determine the column based on the mouse click location, only way I know how is based on column width and order; b.) I would like to save & restore re-arranged columns. ...Show All

• Ken_Bussell dll.config file

  In my Visual Studio 2005 VB Solution I have three projects. A Windows Service, a Class Library, and a Setup and Deployment Project I have a config file for my Class Library project, but I cannot seem to properly get it to be included in the setup without either manually including the file or by including the source files and then applying a filter to it so that only the config file is included. If I set the App.Config file to be "Content" and then add the content, it adds the file as App.dll.Config instead of <Project>.dll.config. (It actually seems to work correctly using the Source Files option, however I am concerned that if the dll project is expanded, some source files might accidentally get added to the setup proje ...Show All

• S&amp;#233;bastien Nunes Gridview elements

  I have a gridview, and i would like in the code, when i check the NO radio button for it to display a text box in the next column. I am new at this and i do not know exactly how to do it. I set up a postback event on the radio buttons. I would appreciate your help Thank you Shot in the dark here, but instead of checking for it constantly, why not just have two events, one when your data is loaded, and one when the radio button changes, and if the new value is the right value, then you can do like myCell.OwningRow.Cells[column_number_of_textbox].Visible = true Does visible work right on a per-cell basis Thanks for your reply, I already have the radio buttons ...Show All

• Paul Burg Highlight the cell with an error...

  Hello everyone! I've got a DataGridView and when the user forgets to enter a value into a required field I would like that field to get focus when the error occours.

• gifuran Problem somewhat solved

  I'm running into this same problem: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=356806&SiteID=1 Databinding seems useless. The idea of the disconnected data model is a really difficult process, mainly because of relational databases. Many of my tables have identities, and if multiple people are hitting the database at once, there is no guarantee that the identity generated in your datagrid is going to be the same when you actually submit the in memory dataset to your database. This makes it a real pain to update related records. Can anyone shed some insight on complex databinding with identities and relationships Perhaps, someone has some good documentation on some methodologies used to create windows forms applicati ...Show All

• Bakerboy60 Prepend new rows to DataGridView instead of append?

  Just like the subject says, I'm looking for a method to prepend new rows to a data-bound datagridview instead of the default append. Thanks in advance for any advice. When you data-bind to a grid, you can only display rows from the datasource. So the solution is to add new rows to your datasource. Have you tried using DataGridView.Rows.Insert(index, row) This should work if you set index to zero I think. Hi, Is your problem solved Thank you, Bhanu. hello I have the same requirement, but your suggestion doesn't work with databound datagridview. Error msg - you cannot add rows to a bound datagridview. so whats the solution to this ...Show All

• Sam Jost IList itemsByProduct = new ArrayList();

  hi all, whats the use of declaration in c# IList itemsByProduct = new ArrayList(); can anybody explain me the technical specification and use of above declaration help me..... IList is an interface, and it is generally considered good practice to code to an interface rather than an implementation. This allows the internals of the method to be hidden from the user. Later, if it is discovered that another type of List would be better, the internal implementation can be chanced without the calling programs need to be aware of this change. Moreover, this thread is the same as http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1062544&SiteID=1 Please avoid posting a same question ...Show All
