Hi,
I have a datagridview that contains the column "Amount".
I also have a textbox
I want the sum of the column "amount" to appear in the textbox
I have tried the following:

VB Code:
Dim total As Integer

For Each row As DataGridViewRow In DataGridView1.Rows
total += row.Cells(amount).Value
Next

txtmon.Text = total

I get the message "Cant find column "amount".
Parametername: ColumnName

Do you guys have an idea what i am doing wrong????

Thanks in advance
Sucharitha

推荐答案

total += row.Cells(amount).Value

更正此行

如果您的列名称为金额"，则应将其用双引号引起来

correct this line

if your column name is ''amount'' then you should write it in double quotes

total += row.Cells("amount").Value

或者您可以按数字访问金额"列，从0开始开始对列进行计数

例如.

or you can access column ''amount'' by number start counting columns from 0 to onwards

eg.

ColumnName
name   address   amount
ColumnIndex
0      1         2

在这里，对于金额" columnName，column-index为2

因此，我们可以将其编写如下

here, for ''amount'' columnName, column-index is 2

so, we can write it as below

total += row.Cells(2).Value 

祝您编码愉快！

Happy Coding!
:)

total += row.Cells("Amount").Value

或者您可以使用变量``amount'':

Or you can use variable ''amount'':

Dim amount As String="Amount"
For Each row As DataGridViewRow In DataGridView1.Rows
total += row.Cells(amount).Value
Next
