WinForm里面改变DataGridView某一行的背景颜色
其实那一句改变行颜色的代码都会写,只是写在哪儿的问题。经研究,这句代码要写到DataGridView里面的某个事件里面。例如:
privatevoid dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
int index = CardCMD.PublicInfoCom.GetLendRecordIndex();
if (index ==0)
{
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Wheat;
}
else if (index ==1)
{
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Wheat;
}
else if (index ==2)
{
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Wheat;
}
}
{
int index = CardCMD.PublicInfoCom.GetLendRecordIndex();
if (index ==0)
{
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Wheat;
}
else if (index ==1)
{
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Wheat;
}
else if (index ==2)
{
this.dataGridView1.Rows[2].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[0].Selected =false;
this.dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Wheat;
this.dataGridView1.Rows[1].DefaultCellStyle.BackColor = Color.Wheat;
}
}
这段代码本人试验过,就是想要的效果,可以改变某一行或者某些行,改变某些行可以如下所写:
privatevoid rowMergeView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
//updateview();
for (int i =0; i <this.rowMergeView1.Rows.Count; i++)
{
try
{
this.rowMergeView1.Rows[i].DefaultCellStyle.BackColor = Color.FromName(softcolor[this.rowMergeView1.Rows[i].Cells["yujing"].Value.ToString()]);
}
catch (Exception ex)
{
new FileOper().writelog(ex.Message);
}
}
}
{
//updateview();
for (int i =0; i <this.rowMergeView1.Rows.Count; i++)
{
try
{
this.rowMergeView1.Rows[i].DefaultCellStyle.BackColor = Color.FromName(softcolor[this.rowMergeView1.Rows[i].Cells["yujing"].Value.ToString()]);
}
catch (Exception ex)
{
new FileOper().writelog(ex.Message);
}
}
}
如果要添加列或者行的话,也要在这个事件里面。但是列或者行的值每改变一次就会触发一次这个事件。可以去网上查一下DataBindingComplete事件的详细信息。
