<code>DataGridViewColumn</code> objects have a <code>Name</code> (shown only in the forms designer) and a <code>HeaderText</code> (shown in the GUI at the top of the column) property. The indexer in your example uses the column's <code>Name</code> property, so since you say that isn't working I assume you're really trying to use the column's header.

There isn't anything built in that does what you want, but it's easy enough to add. I'd use an extension method to make it easy to use:

<pre><code>public static class DataGridHelper
{
 public static object GetCellValueFromColumnHeader(this DataGridViewCellCollection CellCollection, string HeaderText)
 {
 return CellCollection.Cast&lt;DataGridViewCell&gt;().First(c =&gt; c.OwningColumn.HeaderText == HeaderText).Value; 
 }
}
</code></pre>

And then in your code:

<pre><code>foreach (DataGridViewRow row in Rows)
{
 if (object.Equals(row.Cells.GetCellValueFromColumnHeader("xxx"), 123))
 {
 // ...
 }
 }
</code></pre>

blocks|key|95000|text|通过这样做，您将能够访问当前选定的行的"xxx“列名的单元格。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|95001|dataGridView1.SelectedRows[0].Cells["xxx"]|code-block|syntax|javascript|95002|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

By doing this you will be able to access the cell at the "xxx" column name for the currently selected row. 

<pre><code>dataGridView1.SelectedRows[0].Cells["xxx"]
</code></pre>

blocks|key|4710111|text|是的，只需删除引号并添加.Index，即|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4710112|foreach+(DataGridViewRow+row+in+Rows)
{
++++if+(object.Equals(row.Cells[xxx.Index].Value,+123))+|code-block|syntax|javascript|4710113|...that是指如果您的列真正名为xxx，而不是其他名称(如Column1等)。您可以独立设置列名和列标题，因此可以在设计器中签入。|4710114|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Yes, just remove the quotes and add .Index, i.e.

<pre><code>foreach (DataGridViewRow row in Rows)
{
 if (object.Equals(row.Cells[xxx.Index].Value, 123)) 
</code></pre>

...that is if your column is really called xxx and not some other name like Column1, etc. You can set the column name and the column header independantly so check in the designer.

I found this:

<ol>
<li>Right mouse click on the datagridview.</li>
<li>Select from popup menu "Edit columns".</li>
<li>Select column that you want.
Design/(Name) - it's what you were looking for.</li>
</ol>

Sample:

<pre><code>if(dataGridViewProjectList.Rows[dataGridViewProjectList.CurrentCell.RowIndex].Cells["dateendDataGridViewTextBoxColumn"].Value.ToString().Length == 0)
</code></pre>

blocks|key|94973|text|如果您在设计模式下的网格列。然后列名是gridView~~列控件的名称示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|94974|DataGridViewTextBoxColumn+idDataGridViewTextBoxColumn+=+new+DataGridViewTextBoxColumn();

idDataGridViewTextBoxColumn.Name+=+"idDataGridViewTextBoxColumn";|code-block|syntax|javascript|94975|然后你就可以访问这个，你想要的。|94976|row.Cells["idDataGridViewTextBoxColumn"].Value|94977|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

if you grid column in design mode.
then column name was gridView~~~Column controls's name
example :

<pre><code>DataGridViewTextBoxColumn idDataGridViewTextBoxColumn = new DataGridViewTextBoxColumn();

idDataGridViewTextBoxColumn.Name = "idDataGridViewTextBoxColumn";
</code></pre>

then you can access right this, you want.

<pre><code>row.Cells["idDataGridViewTextBoxColumn"].Value
</code></pre>

If your datagridviews columns are dynamic with dedicated headertext, then you can assign a name to that particular column of DGV like this:
<pre class="lang-cs prettyprint-override"><code>dataGridView2.Columns[1].HeaderText = &quot;Invoice No&quot;;
dataGridView2.Columns[1].Name = &quot;invoice_no&quot;;
</code></pre>
and then can use that name as an index like this :
<pre class="lang-cs prettyprint-override"><code>foreach (DataGridViewRow row in rows_with_checked_column)
{
 MessageBox.Show(row.Cells[&quot;invoice_no&quot;].Value.ToString());
}

I have a WinForms application with a <code>DataGridView</code>, which DataSource is a DataTable (filled from SQL Server) which has a column of <code>xxx</code>. The following code raises the exception of 

<blockquote>
 ArgumentException was unhandled. Column named xxx cannot be found.
</blockquote>

<pre><code>foreach (DataGridViewRow row in Rows)
{
 if (object.Equals(row.Cells["xxx"].Value, 123))
}
</code></pre>

Is it possible to get the cell values by column name?
