Question

我想根据某些条件更改gridview的特定行颜色，我使用ASP.NET和c＃。谢谢。

Answer 1

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Attributes.Add("style", "cursor:help;");
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Alternate)
    { 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {                
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#E56E94'");
            e.Row.BackColor = Color.FromName("#E56E94");                
        }           
    }
    else
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='gray'");
            e.Row.BackColor = Color.FromName("gray");                
        }

        //e.Row.Cells[0].BackColor = Color.FromName("gray");
        //e.Row.Cells[1].BackColor = Color.FromName("gray");
        //e.Row.Cells[2].BackColor = Color.FromName("gray");
        //e.Row.Cells[3].BackColor = Color.FromName("gray");
        //e.Row.Cells[4].BackColor = Color.FromName("gray");
        //e.Row.BorderWidth = 2;
        //e.Row.BorderColor = Color.FromName("#43C6DB");
    }
}

Answer 2

protected void DrugGridView_RowDataBound(object sender, GridViewRowEventArgs e)

{
    // To check condition on integer value
    if (Convert.ToInt16(DataBinder.Eval(e.Row.DataItem, "Dosage")) == 50)
    {
      e.Row.BackColor = System.Drawing.Color.Cyan;
    }
}

Answer 3

为您的GridView创建GridView1_RowDataBound事件。

//Check if it is not header or footer row
if (e.Row.RowType == DataControlRowType.DataRow)
{
    //Check your condition here
    If(Condition True)
    {
        e.Row.BackColor = Drawing.Color.Red // This will make row back color red
    }
}

Answer 4

如果在其中一列中出现特定字符串（“TextToMatch”），此方法会修改背景颜色（深红色）和文本（白色）：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.Cells[8].Text.Equals("TextToMatch"))
    {
        e.Row.BackColor = System.Drawing.Color.DarkRed;
        e.Row.ForeColor = System.Drawing.Color.White;
    }
}

或者另一种写作方式：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.Cells[8].Text.Equals("TextToMatch"))
    {
        e.Row.Attributes.CssStyle.Value = "background-color: DarkRed; color: White";
    }
}

Answer 5

或者，您可以将行DataItem强制转换为类，然后根据类属性添加条件。这是我用来将行转换为名为TimetableModel的类/模型的示例，然后在if语句中您可以访问所有类字段/属性：

protected void GridView_TimeTable_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    var tt = (TimetableModel)(e.Row.DataItem);
                     if (tt.Unpublsihed )
                       e.Row.BackColor = System.Drawing.Color.Red;
                     else
                       e.Row.BackColor = System.Drawing.Color.Green;
                }
            }
        }

Answer 6

 protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Label lbl_Code = (Label)e.Row.FindControl("lblCode");
            if (lbl_Code.Text == "1")
            {
                e.Row.BackColor = System.Drawing.ColorTranslator.FromHtml("#f2d9d9");
            }
        }
    }

Answer 7

\\loop throgh all rows of the grid view  

if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value1")
{
   GridView1.Rows[i - 1].ForeColor = Color.Black;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value2")
{
   GridView1.Rows[i - 1].ForeColor = Color.Blue;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value3")
{
   GridView1.Rows[i - 1].ForeColor = Color.Red;
}
else if (GridView1.Rows[i - 1].Cells[4].Text.ToString() == "value4")
{
   GridView1.Rows[i - 1].ForeColor = Color.Green;
}
