在DataGridView C＃中更改单元格的背景颜色 [英] Change background color of cells in DataGridView C#

问题描述

我有一个从文本框（txtSearch）搜索到的DatagridView（dgvEmployeeData）。

Hi,

I have a DatagridView (dgvEmployeeData) that is searched form a textbox (txtSearch).
What I want to happen is when the textbox has text in it I want all the cells in the database that are shown to have their background color changed to YellowGreen and when the textbox has no text in it the color to be changed back to white.

How would I do this?

Any help would be greatly appreciated

嗨朋友....





你是安静的好问题分析仪。



尝试...来编码...



这是解决方案...



在TextBox的 textChanged事件尝试使用DatagridView的 CellFormatting属性和Event 在输入TextBox后立即更改DataGridView的CELL颜色。

Hi Friend....


You are quiet good problem analyzer.

Try...to code this...

Here is the Solution...

on TextBox's textChanged Event try to use the DatagridView's CellFormatting properties and Event to change the Color of DataGridView's CELL as soon as you typed into TextBox.


Happy Programming....:-)

你好，



你可以像这样使用该文本框的TextChanged事件。

Hello ,

you can use TextChanged event of that textbox like this way .

private void txtenter_TextChanged(object sender, EventArgs e)
       {
           if (txtenter.Text.Trim().Length > 0)
           {
               foreach (DataGridViewRow dgvrow in dataGridView1.Rows)
               {
                   dgvrow.DefaultCellStyle.BackColor = Color.YellowGreen;
               }
           }
           else
           {
               foreach (DataGridViewRow dgvrow in dataGridView1.Rows)
               {
                   dgvrow.DefaultCellStyle.BackColor = Color.White;
               }

           }

       }

然后使foreach / for循环设置Datagridview的背景颜色。这里我使用

and then make foreach/ for loop to set the background color of the Datagridview . here i use

Trim()

在文本框中输入值时忽略前导空格。



谢谢

for ignore the leading space while entering value in the textbox .

thanks

我通过添加以下内容解决了左上角单元格未着色的问题：

I fixed the problem of the top left cell being not coloured by adding:

dgvEmployeeData.ClearSelection();

在虚空结束时工作正常



感谢所有帮助

at the end of the void and it works fine

Thanks for all the help
