Enable edit mode in datagridview only for certain column c#
提问by Kaoru
How do i enable edit mode only for the certain column?
如何仅为特定列启用编辑模式？
Let's say i have this columns:
假设我有这个列：
Product Code || Quantity || Description || Price
Product Code || Quantity || Description || Price
I wanted to enable edit mode only for Quantitycolumn and Pricecolumn. The rest cannot be edited.
我只想为Quantity列和Price列启用编辑模式。其余部分无法编辑。
I already did this below code, but it seems not working:
我已经在下面的代码中做了这个，但它似乎不起作用：
dataGridView1.EditMode = DataGridViewEditMode.EditOnKeystroke;
dataGridView1.Columns["Quantity"].ReadOnly = false;
dataGridView1.Columns["Price"].ReadOnly = false;
All i can do is disable ReadOnlyto false, but it is enabled all of the columns that i don't want to enable them.
我所能做的就是关闭ReadOnly到false，但它使所有列的，我不想让他们。
Note: By the time program runs for the first time, i already set the ReadOnlyto true
注：在第一次时间程序运行时，我已经设置ReadOnly到true

You should set ReadOnly = true to all non-editable column. By default, column are set to ReadOnly = false
您应该将 ReadOnly = true 设置为所有不可编辑的列。默认情况下，列设置为 ReadOnly = false

foreach (DataGridViewColumn dc in dgvTestParameter.Columns)
{
if (dc.Index.Equals(0) || dc.Index.Equals(4))
{
dc.ReadOnly = false;
}
else
{
dc.ReadOnly = true;
}
}

int EditableCol_index = datagridview["colname"].index;
// if this is true , you wont be able to edit even you set the column readonly=false;
datagridview1.readonly = false;
foreach (datagridviewcolumns c in datagridview1 )
{
c.readonly = true;
if( c.index == EditableCol_index )
{
c.readonly = false; // editable
}
}

From design part you just check "Enable Editing" mode in your Datagridview. this example may help you,
从设计部分，您只需在 Datagridview 中选中“启用编辑”模式。这个例子可能对你有帮助，
I have added two columns on as readonly purpose(column name is "ReadOnly Column") and another as editable column(column name is "Normal Column").
我添加了两列作为只读目的（列名是“只读列”），另一列作为可编辑列（列名是“普通列”）。
Code:
代码：
dataGridView1.Columns["readOnlyColumn"].ReadOnly = true;
Thank you....
谢谢....

The out-of-box solution is using attributes on your data model:
开箱即用的解决方案是在您的数据模型上使用属性：
public class MyDataModel
{
// Do not show in data grid view
[System.ComponentModel.Browsable(false)]
public virtual int ID { get; protected set; }
// Set to read-only in data grid view
[System.ComponentModel.ReadOnly(true)]
public virtual string Person { get; set; }
}
