Format or pad a number column in DataGridView control (DefaultCellStyle.Format)
提问by Our Man in Bananas
I have a DatagridView control on my form.
我的表单上有一个 DatagridView 控件。
The first column is a Record ID which can be between 3 and 5 digits on the db, but should be formatted on the front end as 5 digits with padded zeros/leading zeros.
第一列是记录 ID，它可以在数据库上的 3 到 5 位数字之间，但应在前端格式化为 5 位数字，并带有填充零/前导零。
So it looks like 901and I want it to look like 00901
所以它看起来像901而我希望它看起来像00901
I looked at

Try this number format "#####00000" Code for testing I had used:
试试这个数字格式“#####00000”我用过的测试代码：
Me.RichTextBox.Text &= String.Format("{0:#####00000}",123)
Me.RichTextBox.Text &= Environment.NewLine
Me.RichTextBox.Text &= String.Format("{0:#####00000}",12345)
Tested in RichTextBox, but sure a same format will working for DefaultCellStyle.Format
在 RichTextBox 中测试，但确定相同的格式适用于 DefaultCellStyle.Format
dgvDeletedRecord.Columns(0).DefaultCellStyle.Format = "#####00000"
In format sting "#"-sign tell how mush number will be show(prefix zeros not shown) Then "0"-sign tell how mush zeros will be shown, and here prefix zeros will be showed
在格式字符串中“#”-符号告诉将如何显示糊状数字（未显示前缀零）然后“0”-符号告诉将如何显示糊状零，此处将显示前缀零
