[英]Add button to certain cell in datagridview
I have created a Datagridview. 我创建了一个Datagridview。 Now whenever the cell contains an empty value, It will add the plus button to the cell.
现在,只要单元格包含空值,它就会将加号按钮添加到单元格中。 Something like this:
像这样的东西:
if ((string)((Hashtable)ht[i])["value"] == "")
{
// Create a Save button column
DataGridViewImageButtonSaveColumn columnSave = new DataGridViewImageButtonSaveColumn();
// Set column values
//Add the columns to the grid6
if (!dataGridView1.Columns.Contains("SaveButton"))
{
dataGridView1.Columns.Insert(5, columnSave);
}
}
else
{
//hide save button.
}
But now my problem is that it display the plus button at all cell for that column even though that particular cell have value. 但现在我的问题是它在该列的所有单元格上显示加号按钮,即使该特定单元格具有值。 How can I hide the button for the cell that have value?
如何隐藏具有值的单元格的按钮?
If you only want buttons in some rows then I would tend not to use a DataGridViewButtonColumn
. 如果您只想要某些行中的按钮,那么我倾向于不使用
DataGridViewButtonColumn
。 I would use a read-only DataGridViewTextBoxColumn
, so that it displays empty cells by default. 我会使用只读的
DataGridViewTextBoxColumn
,因此它默认显示空单元格。 For those rows where you want a button, you would then create a DataGridViewButtonCell
and use the indexer of the grid itself to place that cell at a specific column and row index. 对于那些需要按钮的行,然后创建一个
DataGridViewButtonCell
并使用网格本身的索引器将该单元格放在特定的列和行索引处。
