C# ASP.NET-i'；我正在寻找将子字符串字体更改为gridview单元格的方法

首先在绑定字段上设置

htmlencode=“false”

，如下所示

protected void Button2_Click(object sender, EventArgs e)
    {
        string srchDescription = searchDescription.Text;
        string slctItem = DropDownList1.SelectedItem.ToString();

        con.Open();

        SqlCommand cmdForDescription = new SqlCommand("SELECT Description FROM car_table WHERE Вносител = '" + slctItem + "'", con);
        string descriptionText = cmdForDescription.ExecuteScalar().ToString();
        bool containsDescription = descriptionText.Contains(srchDescription);

        if (containsDescription)
        {

            SqlCommand cmd = new SqlCommand("SELECT * FROM car_table WHERE Вносител = '" + slctItem + "'", con);
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            GridView2.DataSource = ds;
            GridView2.DataBind();
            con.Close();
            Label2.Visible = true;

        }
    } 

gridview的

编写以下内容

<asp:BoundField DataField="Description" HeaderText="Description" 
                 htmlencode="false"   SortExpression="Description" />

if（e.Row.RowType==DataControlRowType.DataRow）
{
string textToReplace=searchDescription.Text；
字符串newText=”“+searchDescription.Text+”；
e、 Row.Cells[4]。Text=e.Row.Cells[4]。Text.Replace（textToReplace，newText）；
}
哪一个是描述字段？对不起，它在我的语言中。。。最后一个是描述->非常感谢！：）很高兴帮助你：）
protected void Button2_Click(object sender, EventArgs e)
    {
        string srchDescription = searchDescription.Text;
        string slctItem = DropDownList1.SelectedItem.ToString();

        con.Open();

        SqlCommand cmdForDescription = new SqlCommand("SELECT Description FROM car_table WHERE Вносител = '" + slctItem + "'", con);
        string descriptionText = cmdForDescription.ExecuteScalar().ToString();
        bool containsDescription = descriptionText.Contains(srchDescription);

        if (containsDescription)
        {

            SqlCommand cmd = new SqlCommand("SELECT * FROM car_table WHERE Вносител = '" + slctItem + "'", con);
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            GridView2.DataSource = ds;
            GridView2.DataBind();
            con.Close();
            Label2.Visible = true;

        }
    } 

<asp:BoundField DataField="Description" HeaderText="Description" 
                 htmlencode="false"   SortExpression="Description" />

if(e.Row.RowType == DataControlRowType.DataRow)
{
   string textToReplace = searchDescription.Text;
   string newText = "<b>" +searchDescription.Text + "</b>";
   e.Row.Cells[4].Text =e.Row.Cells[4].Text.Replace(textToReplace, newText);    
}
