C# 缩进datagridview的某些行

我有一个WinForms应用程序，它使用查询从Access中的表中读取一些数据，并将其打印到datagridview。我只是想知道是否有任何可能的方法，我可以缩进或突出显示一行匹配的“序列号”。应该有两个匹配的“序列号”，但我只想缩进或突出显示其中一个。这是我的东西如果有什么帮助的话

ad.SelectCommand = new OleDbCommand("SELECT b.RSV_CAT, b.SEQNUM, b.LEASE,  b.WELL_ID, a.QUALIFIER, a.KEYWORD, a.EXPRESSION FROM [AC_ECONOMIC] a INNER JOIN [AC_PROPERTY] b on a.PROPNUM=b.PROPNUM WHERE a.KEYWORD = '" + end + "' AND a.QUALIFIER = '" +qual+ "' AND a.EXPRESSION LIKE 'SN%'", con); 

ad3.SelectCommand = new OleDbCommand("SELECT b.RSV_CAT, b.SEQNUM, b.LEASE,  b.WELL_ID, a.QUALIFIER, a.KEYWORD, a.EXPRESSION FROM [AC_ECONOMIC] a INNER JOIN [AC_PROPERTY] b on a.PROPNUM=b.PROPNUM WHERE a.KEYWORD = '" + start + "' AND a.QUALIFIER = '" + qual + "' AND a.EXPRESSION LIKE 'SN%'", con3);

我想用

start

变量或

ad3缩进或突出显示查询。选择Command

。任何帮助都将不胜感激

这里还有一些我的

dataGridView

代码，可以去掉边界

private void newWindow_Load(object sender, EventArgs e)
{            
    this.dataGridView3.AdvancedCellBorderStyle.Left = DataGridViewAdvancedCellBorderStyle.None;
    this.dataGridView3.AdvancedCellBorderStyle.Right = DataGridViewAdvancedCellBorderStyle.None;

    this.dataGridView3.AdvancedCellBorderStyle.Bottom = DataGridViewAdvancedCellBorderStyle.None;
    this.dataGridView3.AdvancedCellBorderStyle.Top = DataGridViewAdvancedCellBorderStyle.None;

    dataGridView3.DataSource = ((Form1)frm1).ds.Tables[0];
}

好的，这是一个非常简单的Winforms DatagridView示例，它在满足特定条件时在单元格上循环并高亮显示行。到目前为止，这是您需要的确切解决方案，但可以给您一个指导原则：-）

---

我在玩指南示例，并对迭代单元格的最后一部分使用了不同的方法。（VB语言）

---

我不确定在不亲自处理绘图的情况下是否进行缩进，但您可以根据自己的喜好格式化（例如，设置颜色）单元格、行甚至列。@有没有办法只对ad3查询进行缩进？我可以通过在循环中遍历DataGridView并识别符合条件的单元格来完成缩进。稍后我将发布一个示例。我附上了一个关于如何检查DataGridView的非常简单的示例。您可以进一步了解这一点，但这可能足以将您推向正确的方向。这确实提供了指导，但我如何只突出显示datagrid中的一个匹配值？很抱歉问了这么多问题。

//Creation of DataTable
DataTable t = new DataTable("myTable");
t.Columns.Add(new DataColumn("Field1", typeof(string)));
t.Columns.Add(new DataColumn("Field2", typeof(int)));
t.Columns.Add(new DataColumn("Field3", typeof(string)));
t.Columns.Add(new DataColumn("Field4", typeof(string)));

//Adding test data to DataTable
t.Rows.Add(new object[] { "Value1", 300, "Test1", "Test2" });
t.Rows.Add(new object[] { "Value2", 1100, "Test3", "Test4" });
t.Rows.Add(new object[] { "Value3", 900, "Test5", "Test6" });
