我在后面的代码中动态创建了 GridView。现在,在实际的 DataBinding 事件中,我有一个 JavaScript 函数可以保存已编辑的单元格及其值。这一切都可以在没有寻呼机的情况下正常工作,现在当我将寻呼机添加到 GW 时,我需要将页面索引添加到 JS 函数中,以便稍后我可以计算出实际更改的行/单元格。
// Databind an edit box in the grid
void edt_DataBinding(object sender, EventArgs e)
{
DropDownList txtData = (DropDownList)sender;
GridViewRow container = (GridViewRow)txtData.NamingContainer;
object dataValue = DataBinder.Eval(container.DataItem, _columnName);
txtData.Attributes.Add("onchange", "sav(" + container.RowIndex.ToString() + "," + _columnName + ",this.value)");
if (dataValue != DBNull.Value)
{
txtData.SelectedItem.Text = dataValue.ToString();
txtData.BackColor = Color.LightGreen;
}
}
我尝试将“grdMain.PageIndex”添加到 JS,但出现以下错误:“无法访问外部类型的非静态成员......
txtData.Attributes.Add("onchange", "sav(" + grdMain.PageIndex + container.RowIndex.ToString() + "," + _columnName + ",this.value)");
任何智能解决方法?

按钮点击:
.....
TemplateField tfUsers = new TemplateField();
grdMain.Columns.Add(tfUsers);
tfUsers.ItemTemplate = new GridViewTemplate(ListItemType.Item, "Name", "0", "String", true, false, "resource", lame);
tfUsers.HeaderTemplate = new GridViewTemplate(ListItemType.Header, "Resource", "0", "String", true, false, "resource", lame);
_dtEntry.Columns.Add("Name");
