Datagridview - 双击时增加数字 [英] Datagridview - increment number on double click

问题描述

嗨 - 我有一个应用程序，它将预设引用（字符串）添加到数据网格视图中的单元格。用户双击第一个单元格（始终在同一列中），第一个单元格将是 - PRG_152_858_ n ，其中 n 是每个双数递增的数字点击一个新的单元格 - 我们从1开始。



我的代码工作得很好，因为它在第一次双击时添加PRG_152_858_1但我无法获得增量工作，我可以看看它为什么不...因为每次执行子时，增量声明都会将数字设置回1.如果我将声明留作dim i作为整数，结果单元格条目将是PRG_152_858_0。



任何人都可以指导我找到正确的解决方案吗？



谢谢

David

Hi - I have an application that adds a pre-set reference (a string) to a cell in a data grid view. The user double clicks on the first cell (always in the same column) where the first reference is to be - "PRG_152_858_n" where n is a number incrementing on each double click in a new cell - we start at 1.

The code I have works fine in that it adds "PRG_152_858_1" on the first double click but I cannot get the increment to work and I can see why it doesn't...because every time the sub is executed, the increment declaration sets the number back to 1. If I leave the declaration as just "dim i as integer", the resulting cell entry will be "PRG_152_858_0".

Can anyone guide me toward the correct solution please?

Thanks
David

Private Sub DataGridView1_MouseDoubleClick(sender As Object, e As MouseEventArgs) Handles DataGridView1.MouseDoubleClick
       Dim i As Integer = 1 'This is the incrementing part of the entry
       Dim Inc As String = txtCurFormat.Text 'refers to the first part of the entry dealt with elsewhere
       DataGridView1.SelectedCells.Item(1).Value = Inc & i
       i = i + 1

   End Sub

推荐答案

破解它!!!



用全局变量替换了i局部变量，现在看起来工作正常。

Cracked it!!!

replaced the i local variable with a global variable and it now seems to work OK.
