如何更改datagridiew最后一行C＃的字体颜色 [英] How to change font color of datagridiew last row C#

问题描述

大家好！我想知道如何在最后一行更改datagridview的forecolor。



我尝试过：



textBox2.Text = Add_Food_Inventory.setaluefortext204;

dateTimePicker1.Text = System.DateTime.Now.ToString（）;

dateTimePicker2.Text = Add_Food_Inventory .setaluefortext202;

dateTimePicker3.Text = Add_Food_Inventory.setaluefortext203;

button1.PerformClick（）;

int sum = 0;

for（int i = 0; i< dataGridView1.Rows.Count; ++ i）

{

sum + = Convert.ToInt32（dataGridView1。行[i] .Cells [1] .Value）;

}

textBox1.Text = sum.ToString（）;

int sum1 = 0;

for（int i = 0; i< dataGridView1.Rows.Count; ++ i）

{

sum1 + = Convert.ToInt32（dataGridView1.Rows [ i] .Cells [2] .Value）;

}

textBox3.Text = sum1.ToString（）;

// PopulateRows（ ）;

int rowIdx = dataGridView1.Rows.Count - 1;

dataGridView1.Rows [rowIdx] .Cells [0] .Value =Total;

dataGridView1.Rows [rowIdx] .Cells [1] .Value = sum;

dataGridView1.Rows [rowIdx] .Cells [2] .Value = sum1;

i想要改变sun和sum1 forecolor in red

解决方案

你可以直接设置（整个）Row BackColor或ForeColor：

 YourRow.DefaultCellStyle.ForeColor = Color.Red; 

您可以通过以下方式设置特定Cell的颜色：

 YourCell.Style.ForeColor = Color.Red; 

StackOverFlow上的这个线程包含许多使用DataGridView Color样式的有价值的例子;我建议你先阅读这篇文章，其中展示了如何使用DataGridVew的RowPrePaint事件：[ ^ ]。



并且，请记住，您可以创建要使用的预定义样式：

 DataGridViewCellStyle YourRedCellStyle = new DataGridViewCellStyle（） ; 
 YourRedCellStyle.ForeColor = Color.Red; 
 
 //正在使用中：
 YourCell.CellStyle = YourRedCellStyle; 

尝试

  if （dataGridView1.Rows.Count >   0 ）
 dataGridView1.Rows [dataGridView1.Rows.Count-1] .DefaultCellStyle.BackColor = Color.Red; 

Hello guys! i want to know how to change forecolor of datagridview last row.

What I have tried:

button1.PerformClick();

}
textBox1.Text = sum.ToString();
int sum1 = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
sum1 += Convert.ToInt32(dataGridView1.Rows[i].Cells[2].Value);
}
textBox3.Text = sum1.ToString();
//PopulateRows();
int rowIdx = dataGridView1.Rows.Count - 1;
dataGridView1.Rows[rowIdx].Cells[0].Value = "Total";
dataGridView1.Rows[rowIdx].Cells[1].Value = sum;
dataGridView1.Rows[rowIdx].Cells[2].Value = sum1;
i want to change sun and sum1 forecolor in red

解决方案

You can set the (entire) Row BackColor or ForeColor directly:

YourRow.DefaultCellStyle.ForeColor = Color.Red;

You can set a particular Cell's colors by:

YourCell.Style.ForeColor = Color.Red;

This thread on StackOverFlow contains a number of valuable examples of working with DataGridView Color styles; I suggest you start by reading this post which shows how to use the DataGridVew's RowPrePaint Event: [^].

And, remember that you can create pre-defined Styles to use:

DataGridViewCellStyle YourRedCellStyle = new DataGridViewCellStyle();
YourRedCellStyle.ForeColor = Color.Red;

// in use:
YourCell.CellStyle = YourRedCellStyle;

try

if (dataGridView1.Rows.Count > 0)
           dataGridView1.Rows[dataGridView1.Rows.Count-1].DefaultCellStyle.BackColor = Color.Red;
