提问by shaik ibrahim
What i want to do is get a value from the data grid. Example: a button onclick will change the color of the cell if the cell value is "test". i have the coding on how to change color but how to do the loop to search the value. Considering that only 1 column has a cell with the value test.
我想要做的是从数据网格中获取一个值。示例：如果单元格值为“test”，则单击按钮将更改单元格的颜色。我有关于如何改变颜色但如何进行循环来搜索值的编码。考虑到只有 1 列具有带有值测试的单元格。

You need to loop thru the rows and search for the text.
您需要遍历行并搜索文本。
in this one you find out how to loop
在这个你会发现如何循环
Visual Basic, How do I read each row in a datagrid?
additionally if you have multiple columns and want to loop thru them too then you have to nest this peace in another loop, something like
此外，如果您有多个列并且也想通过它们循环，那么您必须将这种和平嵌套在另一个循环中，例如
For i As Integer = 0 To DataGridView1.ColumnCount
For Each row As DataGridViewRow In DataGridView1.Rows
If Not row.IsNewRow Then
If row.Cells(i).Value.ToString = "test" Then DataGridView1.Item(i, row.Index).Style.ForeColor = Color.Red
End If
Next
Next i
Good luck
祝你好运
