如何在C＃中编辑搜索结果中的数据 [英] How to edit data in search result in C#
问题描述
我设法为我的编辑按钮和搜索按钮创建了一个代码。我的编辑按钮功能正常。它可以在数据库中编辑我的数据，我的搜索代码也是可用的。我的问题是编辑搜索结果中的数据。就像我搜索火影忍者一样，我的datagridview将过滤所有在数据库上有火影忍者的名字。在我选择并双击结果后，所有数据将重新出现在我的文本框中。但是，当我编辑该数据时，它不起作用。相反，我的数据库中的第一个数据是不会改变我选择的数据。如果我不搜索任何名称而不选择搜索结果，我的编辑代码将正常工作。我认为问题出在我的编辑代码中。请分享你的答案。如果您有代码示例，那就好多了。提前感谢！
这是我的代码。请帮助...
我尝试过：
< pre lang =c＃> private void JOGridView_DoubleClick（ object sender，EventArgs e）
{
DataTable dt = new DataTable（）;
SqlDataAdapter da = new SqlDataAdapter（ 选择*来自JobOrder，con）;
if （JOGridView.CurrentCell！= null &&&&& JOGridView。 CurrentCell.Value！= null ）
{
TBName.Text = JOGridView.SelectedRows [ 0 ].Cells [ 0 ]。Value.ToString（）;
TBContact.Text = JOGridView.SelectedRows [ 0 ]。单元格[ 1 ]。值。的ToString（）;
CBStatus.Text = JOGridView.SelectedRows [ 0 ]。单元格[ 2 ]。值。的ToString（）;
TBModel.Text = JOGridView.SelectedRows [ 0 ]。单元格[ 3 ]。值。的ToString（）;

I managed to create a code for my edit button and search button. My edit button is functional. It can edit my data in database, my search code is also functional. My problem is to edit data in search results. Like if i search "naruto", my datagridview will filter all the names that has "naruto" on the database. After i choose and doubleclick on the result, all data will reappear to my textbox. But when i edit that data, it doesn't work. Instead, the first data on my database is the one that is changing not the one that i choose. My edit code is working if i don't search any names and don't choose on the search result. I think the problem is in my Edit codes. Please share your answers. Much better if you have a code examples. THANKS IN ADVANCE!
here's my codes. Please HELP...
What I have tried:
private void JOGridView_DoubleClick(object sender, EventArgs e)
{
DataTable dt = new DataTable();

if (JOGridView.CurrentCell != null && JOGridView.CurrentCell.Value != null)
{
TBName.Text = JOGridView.SelectedRows[0].Cells[0].Value.ToString();
TBContact.Text = JOGridView.SelectedRows[0].Cells[1].Value.ToString();
CBStatus.Text = JOGridView.SelectedRows[0].Cells[2].Value.ToString();
TBModel.Text = JOGridView.SelectedRows[0].Cells[3].Value.ToString();
TBSerial.Text = JOGridView.SelectedRows[0].Cells[4].Value.ToString();
TBAccess.Text = JOGridView.SelectedRows[0].Cells[5].Value.ToString();
TBRB.Text = JOGridView.SelectedRows[0].Cells[6].Value.ToString();

if (dr == DialogResult.Yes)
{

}Try something like this:
private DataRowView GetCurrentRowData() { if (JOGridView.CurrentCell == null) return null; int rowIndex = JOGridView.CurrentCell.RowIndex; if (rowIndex == -1) return null; return JOGridView.Rows[rowIndex].DataBoundItem as DataRowView; } private void JOGridView_DoubleClick(object sender, EventArgs e) { DataRowView row = GetCurrentRowData(); if (row != null) { TBName.Text = Convert.ToString(row["Name"]); TBContact.Text = Convert.ToString(row["Contact"]); CBStatus.Text = Convert.ToString(row["Status"]); TBModel.Text = Convert.ToString(row["Model"]); TBSerial.Text = Convert.ToString(row["Serial"]); TBAccess.Text = Convert.ToString(row["Access"]); TBRB.Text = Convert.ToString(row["RB"]); TBRP.Text = Convert.ToString(row["RP"]); TBIT.Text = Convert.ToString(row["IT"]); CBRamarks.Text = Convert.ToString(row["Remarks"]); TBCharge.Text = Convert.ToString(row["Charge"]); TBRELB.Text = Convert.ToString(row["RELB"]); } } private void BTNEdit_Click(object sender, EventArgs e) { DataRowView row = GetCurrentRowData(); if (row != null) ( DialogResult dr = MessageBox.Show("Are you sure you want to edit this record?", "Update Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question); if (dr == DialogResult.Yes) { using (var cmd = con.CreateCommand()) { cmd.CommandText = @"UPDATE JobOrder SET Name = @Name, Contact = @Contact, Status = @Status, Model = @Model, Serial = @Serial, Access = @Access, RB = @RB, RP = @RP, IT = @IT, Remarks = @Remarks, Charge = @Charge, RELB = @RELB WHERE ID = @ID ;"; cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@Name", TBName.Text); cmd.Parameters.AddWithValue("@Contact", TBContact.Text); cmd.Parameters.AddWithValue("@Status", CBStatus.Text); cmd.Parameters.AddWithValue("@Model", TBModel.Text); cmd.Parameters.AddWithValue("@Serial", TBSerial.Text); cmd.Parameters.AddWithValue("@Access", TBAccess.Text); cmd.Parameters.AddWithValue("@RB", TBRB.Text); cmd.Parameters.AddWithValue("@RP", TBRP.Text); cmd.Parameters.AddWithValue("@IT", TBIT.Text); cmd.Parameters.AddWithValue("@Remarks", CBRamarks.Text); cmd.Parameters.AddWithValue("@Charge", TBCharge.Text); cmd.Parameters.AddWithValue("@RELB", TBRELB.Text); cmd.Parameters.AddWithValue("@ID", row["ID"]); con.Open(); try { cmd.ExecuteNonQuery(); } finally { con.Close(); } } displayrecords(); MessageBox.Show("Selected record has been updated!", "Done Updating", MessageBoxButtons.OK, MessageBoxIcon.Information); } } clearrecords(); }
(You might need to fix the column names to match your table; I've just guessed based on your control names.)
