img.ImageUrl = change < 0 ? "~/Images/arRed.gif" : "~/Images/arGreen.gif";

label.ForeColor = change < 0 ? Color.Red : Color.Green;

}

}

}

注：模板列中的事件如何写？手工写事件，如btn.OnClick += ...;

注：视图模板请参考文档《ASPxGridView.Templates》

ASPxGridView 事件

RowCreated（创建行数据时触发，类似 GridView 的 DataItemCreate 事件）

protected void grid_HtmlRowCreated(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventArgs e)

{

if(e.RowType != DevExpress.Web.ASPxGridView.GridViewRowType.Data) return;

// 设置模板列lable控件值

Label label = grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changePercent") as Label;

decimal change = (decimal)grid.GetRowValues(e.VisibleIndex, "Change");

label.Text = string.Format("{0:p}", change);

// 设置模板列image控件的图像

System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changeImage");

img.Visible = false;

if(change != 0) {

img.Visible = true;

img.ImageUrl = change < 0 ? "~/Images/arRed.gif" : "~/Images/arGreen.gif";

label.ForeColor = change < 0 ? Color.Red : Color.Green;

}

}

HtmlRowPrepared（行准备？可在此设置行的展示效果，如背景）

protected void grid_HtmlRowPrepared(object sender, ASPxGridViewTableRowEventArgs e)

{

bool hasError = e.GetValue("FirstName").ToString().Length <= 1;

hasError = hasError || e.GetValue("LastName").ToString().Length <= 1;

hasError = hasError || !e.GetValue("Email").ToString().Contains("@");

hasError = hasError || (int)e.GetValue("Age") < 18;

DateTime arrival = (DateTime)e.GetValue("ArrivalDate");

hasError = hasError || DateTime.Today.Year != arrival.Year || DateTime.Today.Month != arrival.Month;

if(hasError) {

e.Row.ForeColor = System.Drawing.Color.Red;

}

}

UnboundColumnData （非绑定列数据填充）

protected void grid_CustomUnboundColumnData(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewColumnDataEventArgs e)

{

if(e.Column.FieldName == "Total")

{

decimal price = (decimal)e.GetListSourceFieldValue("UnitPrice");

int quantity = Convert.ToInt32(e.GetListSourceFieldValue("Quantity"));

e.Value = price * quantity;

}

}

CustomColumnDisplayText（定制列文本展示）

protected void grid_CustomColumnDisplayText(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewColumnDisplayTextEventArgs e)

{

if(object.Equals(e.Column, grid.Columns["Size"]))

e.DisplayText = GetSizeDisplayText(e.Value);

}

SummaryDisplayText（合计行文本展示）

protected void grid_SummaryDisplayText(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewSummaryDisplayTextEventArgs e) {

if(e.Item.FieldName == "Size") {

e.Text = GetSizeDisplayText(e.Value);

}

}

HeaderFilterFillItems（自定义过滤器处理逻辑）

protected void grid_HeaderFilterFillItems(object sender, ASPxGridViewHeaderFilterEventArgs e)

{

if(object.Equals(e.Column, grid.Columns["Total"])) {

PrepareTotalFilterItems(e);

return;

}

if(object.Equals(e.Column, grid.Columns["Quantity"])) {

PrepareQuantityFilterItems(e);

return;

}

}

---------------------------------------------------------

回调处理

---------------------------------------------------------

CustomCallback（Ajax 回调处理）

<select id="selGridLayout" onchange="grid.PerformCallback(this.value);" >

<option selected="selected" value="0">Country</option>

<option value="1">Country, City</option>

<option value="2">Company Name</option>

</select>

protected void grid_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e)

{

int layoutIndex = -1;

if(int.TryParse(e.Parameters, out layoutIndex))

ApplyLayout(layoutIndex); // 更换布局

}

CustomButtonCallback（定制按钮的ajax回调处理）

protected void grid_CustomButtonCallback(object sender, ASPxGridViewCustomButtonCallbackEventArgs e)

{

if(e.ButtonID != "Copy") return;

copiedValues = new Hashtable();

foreach(string fieldName in copiedFields)

copiedValues[fieldName] = grid.GetRowValues(e.VisibleIndex, fieldName);

grid.AddNewRow();

}

---------------------------------------------------------

{

if(grid.IsEditing && !grid.IsNewRowEditing && e.Column.FieldName == "City")

{

string country = (string)grid.GetRowValuesByKeyValue(e.KeyValue, "Country");

ASPxComboBox combo = e.Editor as ASPxComboBox;

FillCityCombo(combo, country);

combo.Callback += new CallbackEventHandlerBase(cmbCity_OnCallback);

}

}

if(!grid.IsNewRowEditing) {

grid.DoRowValidation();

}

}

RowValidating （行数据验证）

protected void grid_RowValidating(object sender, DevExpress.Web.Data.ASPxDataValidationEventArgs e)

{

foreach(GridViewColumn column in grid.Columns) {

GridViewDataColumn dataColumn = column as GridViewDataColumn;

if(dataColumn == null) continue;

if(e.NewValues[dataColumn.FieldName] == null) {

e.Errors[dataColumn] = "Value can't be null.";

}

}

if(e.Errors.Count > 0) e.RowError = "Please, fill all fields.";

if(e.NewValues["FirstName"] != null && e.NewValues["FirstName"].ToString().Length < 2) {

AddError(e.Errors, grid.Columns["FirstName"], "First Name must be at least two characters long.");

}

if(e.NewValues["LastName"] != null && e.NewValues["LastName"].ToString().Length < 2) {

AddError(e.Errors, grid.Columns["LastName"], "Last Name must be at least two characters long.");

}

if(e.NewValues["Email"] != null && !e.NewValues["Email"].ToString().Contains("@")) {

AddError(e.Errors, grid.Columns["Email"], "Invalid e-mail.");

}

int age = 0;

int.TryParse(e.NewValues["Age"] == null ? string.Empty : e.NewValues["Age"].ToString(), out age);

if(age < 18) {

AddError(e.Errors, grid.Columns["Age"], "Age must be greater than or equal 18.");

}

DateTime arrival = DateTime.MinValue;

DateTime.TryParse(e.NewValues["ArrivalDate"] == null ? string.Empty : e.NewValues["ArrivalDate"].ToString(), out arrival);

if(DateTime.Today.Year != arrival.Year || DateTime.Today.Month != arrival.Month) {

AddError(e.Errors, grid.Columns["ArrivalDate"], "Arrival date is required and must belong to the current month.");

}

if(string.IsNullOrEmpty(e.RowError) && e.Errors.Count > 0) e.RowError = "Please, correct all errors.";

if (e.NewValues["Name"] == null)

{

e.RowError = "功能名称不能为空，请填写功能名称";

return;

}

if (e.NewValues["Remarks"] == null)

{

e.RowError = "功能备注不能为空，请填写功能备注";

return;

}

}

行修改事件 RowUpdating

protected void gvFunction_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e)

{

functionModel.Name = e.NewValues[0].ToString();// 组名称

functionModel.Remarks = e.NewValues[1].ToString(); // 组备注

functionModel.FunctionId = e.Keys[0].ToString();// ID

rmodel = client.FunctionEdit(functionModel);// 返回类型表

gvFunction.CancelEdit();//结束编辑状态

e.Cancel = true;

FunctionDataBind();//更新数据

}

行添加事件RowInserting

protected void gvFunction_RowInserting(object sender, DevExpress.Web.Data.ASPxDataInsertingEventArgs e)

{

functionModel.Name = e.NewValues[0].ToString();// 组名称

e.Cancel = true;

FunctionDataBind();//更新数据

}

初始化回调事件 Callback

{

strGroupID = e.Parameter.ToString();

DataBindInfo();// 初始化页面信息

SelectUser();// 查找组里面的所有用户

DataCheck();

}

获取行展开改变事件 DetailRowExpandedChanged

{

SYSolution_WebUI.ServiceReference.GroupInfo groupInfoModel = (SYSolution_WebUI.ServiceReference.GroupInfo)((ASPxGridView)sender).GetRow(e.VisibleIndex);// 获取选中行实体

ASPxGridView gv = (ASPxGridView)gvGroup.FindDetailRowTemplateControl(e.VisibleIndex, "gvGroupName"); // 获取模板内aspxgridView ID名称

SYSolution_WebUI.ServiceReference.GroupInfo[] model = client.GroupSelUserList("GroupId='" + groupInfoModel.GroupId + "'");// 通过组ID值获取实体对象
