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????

total += row.Cells(amount).Value

correct this line

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

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

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

eg.

ColumnName
name   address   amount
ColumnIndex
0      1         2

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

so, we can write it as below

VB

total += row.Cells(2).Value

Happy Coding!

Solution 2

If you have column "Amount", then use the same name in your statement:

VB

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

Or you can use variable 'amount':

VB

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