datagridview

问题 I have DataGridView on my form application. After retrieving data from a table in the database and displaying them in DataGridView , I apply a green color to some cell's BackColor of the rows if a certain condition is met. After those cells are colored green , the program makes them go through another condition, which colors the whole row's BackColor red if they fail to satisfy the condition.

问题 I want to add a button to each row of a column of an already bounded datagridview, and add an event to it (in VS 2005, Windows application). I have searched a lot but was unable to find a working solution. 回答1: before binding to the datasource set : grd.AutoGenerateColumns = false; create yourself all DataGridView columns and bind them to the datasource: DataGridViewTextBoxColumn dgvc = new DataGridViewTextBoxColumn(); dgvc.HeaderText = "column_header"; dgvc.DataPropertyName = "column_name";

Using the debugger, I have looked in the DGV and in the BindingSource and the correct data is there. It is just not displaying in the DGV. Here is my code - I do realize that it is semi-redundant but, at this point, I'm four hours into it and am willing to try anything. this.iSOXTableAdapter.FillByISOX(this

问题 in my C# 4.0 Application, I have a DataGridView to display some data. I want the Columns size accordingly to the content, so I set the AutoSizeColumnsMode to AllCellsExceptHeader.
