我必须写一个DataGridView
并以编程方式填充它。
我想当用户搜索一个单词(例如关键字)并且有包含它的单元格(例如其关键字)时,只需突出显示关键字中搜索到的单词关键字,而不是all关键字,或者不显示单元格或行。
这是填充DataGridView
的代码:
private void Fill()
{
try
{
if (dataGridView1 != null)
{
dataGridView1.ColumnCount = 11;
dataGridView1.Columns[0].HeaderText = Resources.Form1_Fill_ID;
dataGridView1.Columns[1].HeaderText = Resources.Form1_Fill_Family;
dataGridView1.Columns[2].HeaderText = Resources.Form1_Fill_Cellphone;
dataGridView1.Columns[3].HeaderText = Resources.Form1_Fill_Phone1;
dataGridView1.Columns[4].HeaderText = Resources.Form1_Fill_Phone2;
dataGridView1.Columns[5].HeaderText = Resources.Form1_Fill_Phone3;
dataGridView1.Columns[6].HeaderText = Resources.Form1_Fill_Fax;
dataGridView1.Columns[7].HeaderText = Resources.Form1_Fill_CompanyName;
dataGridView1.Columns[8].HeaderText = Resources.Form1_Fill_Agency;
dataGridView1.Columns[9].HeaderText = Resources.Form1_Fill_Brands;
dataGridView1.Columns[10].HeaderText = Resources.Form1_Fill_Address;
dataGridView1.Columns[0].Name = Resources.Form1_Fill_ID;
dataGridView1.Columns[1].Name = Resources.Form1_Fill_Family;
dataGridView1.Columns[2].Name = Resources.Form1_Fill_Cellphone;
dataGridView1.Columns[3].Name = Resources.Form1_Fill_Phone1;
dataGridView1.Columns[4].Name = Resources.Form1_Fill_Phone2;
dataGridView1.Columns[5].Name = Resources.Form1_Fill_Phone3;
dataGridView1.Columns[6].Name = Resources.Form1_Fill_Fax;
dataGridView1.Columns[7].Name = Resources.Form1_Fill_CompanyName;
dataGridView1.Columns[8].Name = Resources.Form1_Fill_Agency;
dataGridView1.Columns[9].Name = Resources.Form1_Fill_Brands;
dataGridView1.Columns[10].Name = Resources.Form1_Fill_Address;
}
_conn.ConnectionString = _connectionString;
var cmd = new OleDbCommand("Select * from contacts ", _conn);
_conn.Open();
OleDbDataReader reader = cmd.ExecuteReader();
int i = 0;
while (reader != null && reader.Read())
{
if (dataGridView1 != null)
{
dataGridView1.Rows.Add(1);
}
if (dataGridView1 != null)
{
var row = dataGridView1.Rows[i];
row.Cells[Resources.Form1_Fill_ID].Value = reader[0].ToString();
row.Cells[Resources.Form1_Fill_Family].Value = reader[1].ToString();
row.Cells[Resources.Form1_Fill_Cellphone].Value = reader[2].ToString();
row.Cells[Resources.Form1_Fill_Phone1].Value = reader[3].ToString();
row.Cells[Resources.Form1_Fill_Phone2].Value = reader[4].ToString();
row.Cells[Resources.Form1_Fill_Phone3].Value = reader[5].ToString();
row.Cells[Resources.Form1_Fill_Fax].Value = reader[6].ToString();
row.Cells[Resources.Form1_Fill_CompanyName].Value = reader[7].ToString();
row.Cells[Resources.Form1_Fill_Agency].Value = reader[8].ToString();
row.Cells[Resources.Form1_Fill_Brands].Value = reader[9].ToString();
row.Cells[Resources.Form1_Fill_Address].Value = reader[10].ToString();
}
i++;
}
}
catch (Exception ex)
{
return;
}
finally
{
_conn.Close();
}
}
这是搜索代码
private void searchBtn_Click(object sender, EventArgs e)
{
// Code to search the alphanumneric Part Number (in Column1 header called "PART NUMBER") and highlihgt the row
foreach (DataGridViewRow row in dataGridView1.Rows)
{
try
{
if (row.Cells[0].Value.ToString().Contains(searchTxt.Text))
//row.Cells[0].Style.ForeColor = Color.Red;
{
var t = row.Cells[0].Value.ToString();
}
if (row.Cells[1].Value.ToString().Contains(searchTxt.Text))
row.Cells[1].Style.ForeColor = Color.Red;
if (row.Cells[2].Value.ToString().Contains(searchTxt.Text))
row.Cells[2].Style.ForeColor = Color.Red;
if (row.Cells[3].Value.ToString().Contains(searchTxt.Text))
row.Cells[3].Style.ForeColor = Color.Red;
if (row.Cells[4].Value.ToString().Contains(searchTxt.Text))
row.Cells[4].Style.ForeColor = Color.Red;
if (row.Cells[5].Value.ToString().Contains(searchTxt.Text))
row.Cells[5].Style.ForeColor = Color.Red;
if (row.Cells[6].Value.ToString().Contains(searchTxt.Text))
row.Cells[6].Style.ForeColor = Color.Red;
if (row.Cells[7].Value.ToString().Contains(searchTxt.Text))
row.Cells[7].Style.ForeColor = Color.Red;
if (row.Cells[8].Value.ToString().Contains(searchTxt.Text))
row.Cells[8].Style.ForeColor = Color.Red;
if (row.Cells[9].Value.ToString().Contains(searchTxt.Text))
row.Cells[9].Style.ForeColor = Color.Red;
if (row.Cells[10].Value.ToString().Contains(searchTxt.Text))
row.Cells[10].Style.ForeColor = Color.Red;
}
catch (Exception)
{
return;
}
}
}
最佳答案
如果此搜索仅取决于客户端加载的数据,那么为什么不建议客户使用浏览器搜索功能。
如果仍然必须向客户提供此功能,那么为什么要使用服务器端代码来执行此任务...。您可以使用javascript处理此问题。
以下是示例链接,该链接说明了如何使用javascript访问datagridview。
