GridView中如何根据某一列值改变行的颜色

[wsdydmw]

我的一个GridView中有[编号] [姓名] [成绩]三列
如果某一行的[成绩]的值小于60 则将这行背景设置为红色。

[vip__888]

if("成绩"<60)
{
//设置一下grv当前行的style.Color
}

[以专业开发人员为伍]

简单：

<asp:Label ID="lbl成绩" runat="server" Text='<%# CheckBack((int)Eval("Age"),(GridViewRow)Container) %>'></asp:Label>

protected int CheckBack(int value, GridViewRow row)
{
    if (value < 60)
        row.BackColor = Color.Red;
    return value;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
        if (e.Row.RowIndex >= 0)
        {
            double number1 = double.Parse(e.Row.Cells[2].Text.ToString());//数量1
              double number2 = double.Parse(e.Row.Cells[5].Text.ToString());//数量2
              if (number1 < number2 )
            {
                e.Row.BackColor = System.Drawing.Color.SkyBlue;//显示颜色，可自定义
            }

        }
}

              if (number1 < 60)
            {
                e.Row.BackColor = System.Drawing.Color.Red;//显示红色
            }

        }
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label labValue = (Label)e.Row.FindControl("lab");
if (labValue.Text == "100")
{
e.Row.BackColor = System.Drawing.Color.Red;
}
}
}

我暂时想到的和5楼的一样.就是在rowdatabound的时候判断一下对应列的值,如果符合条件,则对该行进行处理

C# code

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex >= 0)
{
double number1 = double.Parse(e.Row.Cells[2].Text.T……

正解！！！

3,4,6楼都行

[happy664618843]

dataview dr=ds.Tables[0].DefaultView;
if(Convert.ToInt32(dr["score"])<60){
e.Rows.cells[1].BackColor=System.Drawing.Color.red;
}

[happy664618843]

还有一种方法:
前台绑定 <tr style=SetColor(<%#DataBinder.Eval(Container.DataItem,"score")%>)>
public string SetColor(scrore){
if(score<60){
return "color:red";
}
else{
return "color: white";
}
}

简单：

HTML code
<asp:Label ID="lbl成绩" runat="server" Text='<%# CheckBack((int)Eval("Age"),(GridViewRow)Container) %>'></asp:Label>


C# code
protected int CheckBack(int value, GridViewRow row)

支持这种写法！！

1,2L精神可嘉,..大半夜的不容易..= =
恭喜lz功德圆满.

[ajq1989]

private void DataGridView1_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)
{
if (this.DataGridView1.Columns[e.ColumnIndex].Name.ToString().Equals("Column2"))
{
if (DataGridView1["Column2", e.RowIndex].Value.ToString().ToLower().Equals("true"))
{
DataGridView1["Column1", e.RowIndex].ReadOnly = false;
}
else
{
DataGridView1["Column1", e.RowIndex].ReadOnly = true;
}
}
}

11楼的方法我算学习到了
