[DevExpress]gridcontrol中单元格属性设置为RepositoryItemCheckEdit

默认情况下，RepositoryItemCheckEdit的空值，会显示为灰色半选中状态，要想改为白色空状态，需要修改NullStyle属性为Unchecked。 如果RepositoryItemCheckEdit所在的列未绑定数据源，那么该列默认只可以单选；如果绑定了数据源，那么可以同时多选。 ColumEdit关联FieldName数据源，但是在设计功能中并不仅仅这样就可以同时多选 窗体初始化时：

this.repositoryItemCheckEdit1.QueryCheckStateByValue += new DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventHandler(this.repositoryItemCheckEdit1_QueryCheckStateByValue); gridView1.OptionsSelection.MultiSelect = true; 

实现注册事件：

private void repositoryItemCheckEdit1_QueryCheckStateByValue(object sender, DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventArgs e) { string val = ""; if (e.Value != null) { val = e.Value.ToString(); } else { val = "False";//默认为不选  } switch (val) { case "True": case "Yes": case "1": e.CheckState = CheckState.Checked; break; case "False": case "No": case "0": e.CheckState = CheckState.Unchecked; break; default: e.CheckState = CheckState.Unchecked; break; } e.Handled = true; } 

在绑定数据源的情况下实现只可以单选，可以通过循环每行的状态来实现

/// /// 选择状态改变触发事件 /// /// /// private void repositoryItemCheckEdit1_CheckedChanged(object sender, EventArgs e) { DataTable dt = gridControl1.DataSource as DataTable; for (int i = 0; i < dt.Rows.Count; i++) { dt.Rows[i]["Select"] = false; } gridControl1.RefreshDataSource(); } 

绑定数据源后的全选和反选

//全选 private void btnSelectAll_Click(object sender, EventArgs e) { DataTable dt = gridControl1.DataSource as DataTable; foreach (DataRow dr in dt.Rows) { dr["Select"] = "True"; } } 

//反选 private void btnInvertSelect_Click(object sender, EventArgs e) { DataTable dt = gridControl1.DataSource as DataTable; foreach (DataRow dr in dt.Rows) { string str = dr["Select"].ToString(); if (str == "True") dr["Select"] = "False"; else dr["Select"] = "True"; } } 

获取勾选记录：

private void GetRecord(object sender, EventArgs e) { List<string> delList = new List<string>(); if (gridView1.FocusedRowHandle >= 0) { for (int i = 0; i < gridView1.RowCount; i++) { string obj = gridView1.GetRowCellValue(i, "Select").ToString(); if (obj.Equals("True")) { string id = this.gridView1.GetRowCellValue(i, "i_id").ToString(); delList.Add(id); } } if (delList.Count > 0) { DialogResult result = MessageBox.Show("确定删除记录？", "删除", MessageBoxButtons.YesNo, MessageBoxIcon.Question); if (result == DialogResult.Yes) { string strDel = string.Join(",", delList); pADOHelper.ExecuteNonQuery(string.Format("DELETE from {0} where i_id in ({1})", CommonClass.tableConfigMapLayers, strDel)); RefreshMapLayers(); } } else MessageBox.Show("请勾选数据"); return; } }
