C# DataGridView中实现勾选存储数据和右键删除数据(示例代码)
作者：caoguanghui0804
这篇文章主要介绍了C# DataGridView中实现勾选存储数据和右键删除数据的示例代码，通过示例代码给大家展示运行效果图，需要的朋友可以参考下
DataGridView事件CellContentClick
触发dataGridView的CellContentClick事件，并且在事件中调用Edit 方法。
实现DataGridView中添加CheckBox后不满足条件去掉勾选
并且实现勾选后将绑定数据的存入表的动作
点击确定后去掉勾选
Main.cs
private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
switch (this.tabControl1.SelectedIndex)
{
//case 0:
// //显示数据
// ShowVlues();
// break;
case 1:
TableDefine.Initial_TableE();
for (int i = 0; i <= TableDefine.tGridField.Length - 1; i++)
{
cboSearch.Items.Add(TableDefine.tGridField[i].sCaption);
cboSearchList.Items.Add(TableDefine.tGridField[i].sFieldName);
}
if (cboSearch.Items.Count > 0)
{
cboSearch.SelectedIndex = 0;
}
//取机种
DataTable ModelDT = fslConn.GetAllModel();
if (ModelDT.Rows.Count > 0)
{
foreach (DataRow item in ModelDT.Rows)
{
cboModel.Items.Add(item[0]);
}
}
//取流程
DataTable RouteDT = fslConn.GetAllRoute();
if (RouteDT.Rows.Count > 0)
{
foreach (DataRow item in RouteDT.Rows)
{
cboRoute.Items.Add(item[0]);
}
}
//显示数据
ShowEVlues();
break;
}
}
//取数据显示
void ShowEVlues()
{
string sFieldName = string.Empty;
string sFieldText = string.Empty;
if (cboSearch.SelectedIndex > -1 && txtSearch.Text.Trim() != "")
{
sFieldName = cboSearchList.Items[cboSearch.SelectedIndex].ToString();
sFieldText = txtSearch.Text.Trim();
}
if (string.IsNullOrWhiteSpace(sFieldText))
gvDataE.DataSource = fslConn.GetAllFslEName();
else
gvDataE.DataSource = fslConn.GetAllFslEName(sFieldName, sFieldText);
//栏位title
for (int i = 0; i <= gvDataE.Columns.Count - 1; i++)
{
gvDataE.Columns[i].Visible = false;
}
for (int i = 0; i < TableDefine.tGridField.Length; i++)
{
string sGridField = TableDefine.tGridField[i].sFieldName;
if (gvDataE.Columns.Contains(sGridField))
{
gvDataE.Columns[sGridField].HeaderText = TableDefine.tGridField[i].sCaption;
gvDataE.Columns[sGridField].DisplayIndex = i; //栏位显示顺序
gvDataE.Columns[sGridField].Visible = true;
}
}
gvDataE.Focus();
//为dgv增加复选框列
DataGridViewCheckBoxColumn checkbox = new DataGridViewCheckBoxColumn();
//列显示名称
checkbox.HeaderText = "选择";
checkbox.Name = "IsChecked";
checkbox.TrueValue = true;
checkbox.FalseValue = false;
checkbox.DataPropertyName = "IsChecked";
//列宽
checkbox.Width = 50;
//列大小不改变
checkbox.Resizable = DataGridViewTriState.False;
//添加的checkbox在dgv第一列
this.gvDataE.Columns.Insert(0, checkbox);
}
//实现搜索
private void txtSearch_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar != (char)Keys.Return)
return;
ShowEVlues();
editFilter.Focus();
}
//实现通过流程取站点
private void cboRoute_SelectedIndexChanged(object sender, EventArgs e)
{
if (cboRoute.Text != "")
{
//取站点
DataTable StationTypeDT = fslConn.GetAllStationType(cboRoute.Text);
if (StationTypeDT.Rows.Count > 0)
{
for (int i = 0; i < StationTypeDT.Rows.Count; i++)
{
//cboStationType.Items.Add(item[0]);
cboStationType.Items.Add(new Metadata(StationTypeDT.Rows[i][2].ToString(), StationTypeDT.Rows[i][0].ToString(), StationTypeDT.Rows[i][1].ToString()));
}
}
}
}
//点击勾选事件后进行数据绑定
private void gvDataE_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
string Model = cboModel.Text;
string Route = cboRoute.Text;
if (Model == "" || Route == ""|| cboStationType.Text == "")
{
MessageBox.Show("机种、流程、站点不能为空，请检查!");
//DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)this.gvDataE.Rows[e.RowIndex].Cells["IsChecked"];
// this.gvDataE.Rows[e.RowIndex].Cells["IsChecked"].Value = false;
//将勾选去掉
this.gvDataE.RefreshEdit();
return;
}
//站点代码
string StationType = ((Metadata)cboStationType.SelectedItem).ID;
//站点描述
string StationTypeDesc = ((Metadata)cboStationType.SelectedItem).NAMEDESC;
if (e.ColumnIndex == 0 && e.RowIndex != -1)
{
//获取控件的值
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)this.gvDataE.Rows[e.RowIndex].Cells["IsChecked"];
Boolean flag = Convert.ToBoolean(checkCell.Value);
//KP品名
string gvFunName = gvDataE.Rows[e.RowIndex].Cells["MAT_TYPE_CODE"].Value.ToString();
//KP品名描述
string gvFunNameDesc = gvDataE.Rows[e.RowIndex].Cells["MAT_TYPE_DESC"].Value.ToString();
if (flag == false)
{
checkCell.Value = true;
//添加权限
fslConn.SaveFslPower(gvFunName, gvFunNameDesc, Model,StationType, StationTypeDesc);
}
}
}
ComboBox取值
main.cs
//取机种
DataTable ModelDT = fslConn.GetAllModel();
if (ModelDT.Rows.Count > 0)
{
foreach (DataRow item in ModelDT.Rows)
{
cboModel.Items.Add(item[0]);
}
}
fslConn.cs
//取机种
public DataTable GetAllModel()
{
return fslDAL.GetAllModel();
}
fslDAL.cs
//取机种
public DataTable GetAllModel()
{
string sql = "SELECT MODEL FROM IMES.M_MODEL";
return utility.Query(sql);
}
储存数据
fslConn.cs
public long SaveFslPower(string gvFunName, string gvFunNameDesc, string Model, string StationType, string StationTypeDesc )
{
return fslDAL.SaveFslPower(gvFunName, gvFunNameDesc, Model, StationType, StationTypeDesc);
}
fslDAL.cs
//存权限
public long SaveFslPower(string gvFunName, string gvFunNameDesc, string Model, string StationType, string StationTypeDesc)
{
string id = GetMaxId();
string sql = @"INSERT INTO IMES.M_STATIONTYPE_PARTSPEC (ID,MODEL,STATION_TYPE,STATION_DESC,KP_SPEC,KP_SPEC_DESC,QTY,ENABLED,CREATE_EMPNO,CREATE_TIME,UPDATE_EMPNO)
VALUES(:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)";
object[] para = new object[] { id, Model, StationType , StationTypeDesc,gvFunName, gvFunNameDesc, "1", "Y", utility.GlobalUserNo,DateTime.Now, utility.GlobalUserNo };
return utility.ExecuteSql(sql, para);
}
右键删除数据
实现效果
Main.cs
//实现DataGridView栏位右键删除数据
private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)
{
if (gvData.Rows.Count == 0 || gvData.CurrentRow == null)
{
return;
}
string ID = gvData.CurrentRow.Cells["ID"].Value.ToString();
if (MessageBox.Show("ID:" + ID + " 确认删除吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
//M_STATIONTYPE_PARTSPEC_HT写入历史库
fslConn.SaveFslHistoryData(ID);
移除权限
fslConn.DeleteFslByIDAndFunc(ID);
//显示数据
ShowVlues();
}
}
fslConn.cs
//删除权限
public long DeleteFslByIDAndFunc(string id)
{
return fslDAL.DeleteFslByIDAndFunc( id);
}
fslDAL.cs
//删除权限
public long DeleteFslByIDAndFunc(string id)
{
string sql = @"Delete from IMES.M_STATIONTYPE_PARTSPEC WHERE ID =:1";
object[] para = new object[] { id };
return utility.ExecuteSql(sql, para);
}
