在DataGridViewImageColumn绑定文本字段中显示图像 [英] Showing image in a DataGridViewImageColumn binding text-field

问题描述

我正在使用WindowsForm项目，而且我的表单中我有一个 DataGridView ，一个 DataGridViewImageColumn 使用图片显示行（启用/停用）的状态。

我有一个 DataTable 我绑定到我的datagrid。在这个表格中，有一列是每列的状态，是一个文本字段。

如何将此列绑定到 DataGridViewImageColumn 显示正确的图像？

解决方案

只要我对DataGridView中的事情有任何疑问，请先咨询Microsoft的FAQ。

通常我在这种情况下做的是处理CellFormatting事件根据单元格中的值设置图像。

所以我将图像存储在像图像列表中，然后在CellFormatting中编写如下代码：

  private void dgv_CellFormatting（object sender，DataGridViewCellFormattingEventArgs e）
 {
 if（dgv.Columns [e .ColumnIndex] .Name ==status）
 {
 if（e.Value！= null）
 {
 if（e.Value.ToString（）== 1）
 {
 e.Value = imageList1.I法师[1]; 
} 
 else 
 {
 e.Value = imageList1.Images [2]; 
} 
} 
} 
} 
  

I'm working on a WindowsForm project and in my form I have a DataGridView with a DataGridViewImageColumn which must show the status of the row (enabled/disabled) using an image.

I have a DataTable that I bind to my datagrid. In this table there is a column that is the status of each row and is a text field.

How can I bind this column to the DataGridViewImageColumn showing the right image?

解决方案

Whenever I have questions on how to do things in a DataGridView I consult Microsoft's FAQ first.

http://www.windowsclient.net/Samples/Go%20To%20Market/DataGridView/DataGridView%20FAQ.doc

Typically what I do in that situation is handle the CellFormatting event to set the image based on the value in the cell.

So I would store my images in something like an image list, then have code in CellFormatting like the following:

private void dgv_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (dgv.Columns[e.ColumnIndex].Name == "status")
    {
        if (e.Value != null)
        {
            if (e.Value.ToString() == "1")
            {
                e.Value = imageList1.Images[1];
            }
            else
            {
                e.Value = imageList1.Images[2];
            }
        }
    }
}
