How to change width of DataGridView Columns
提问by stackexchange12
I have a vb.net windows forms application with a datagridview. I'm hoping to find a way to change the width for multiple columns in a datagridview. This is what I have so far, but it only changes the width for the first column not the rest. I appreciate any help you may give.
我有一个带有 datagridview 的 vb.net windows 窗体应用程序。我希望找到一种方法来更改 datagridview 中多列的宽度。到目前为止，这是我所拥有的，但它只更改了第一列的宽度，而不是其余列的宽度。我感谢您提供的任何帮助。
Dim columnwidth1 As DataGridViewColumn = DataGridView1.Columns(0)
columnwidth1.Width = 100
Dim columnwidth2 As DataGridViewColumn = DataGridView1.Columns(1)
columnwidth2.Width = 100
Dim columnwidth3 As DataGridViewColumn = DataGridView1.Columns(2)
columnwidth3.Width = 100
Dim columnwidth4 As DataGridViewColumn = DataGridView1.Columns(3)
columnwidth4.Width = 100

Check that you do not have code to change it back (perhaps in the ColumnWidthChangedevent); and check if AutoSizeColumnsModeis on. Also, you can iterate columns rather than do it individually:
检查您是否没有将其改回的代码（可能在ColumnWidthChanged事件中）；并检查是否AutoSizeColumnsMode打开。此外，您可以迭代列而不是单独执行：
For Each c As DataGridViewColumn In DataGridView1.Columns
c.Width = 50
Next
