总结ASPxGridView的使用 - 图文

label.Text = string.Format(\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, \e\

img.Visible = false; if(change != 0) {

img.Visible = true;

img.ImageUrl = change < 0 ? \: \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(\<= 1; hasError = hasError || e.GetValue(\<= 1;

hasError = hasError || !e.GetValue(\ hasError = hasError || (int)e.GetValue(\< 18;

DateTime arrival = (DateTime)e.GetValue(\

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 == \ {

decimal price = (decimal)e.GetListSourceFieldValue(\ int quantity = Convert.ToInt32(e.GetListSourceFieldValue(\\

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[\ 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 == \{

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[\{ PrepareTotalFilterItems(e); return; }

if(object.Equals(e.Column, grid.Columns[\{ PrepareQuantityFilterItems(e); return; } }

--------------------------------------------------------- 回调处理

--------------------------------------------------------- CustomCallback（Ajax 回调处理）

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, ASPxGridViewC
