我有一个用于控制 Obout 网格数据源的下拉列表。
<obout:OboutDropDownList runat="server" ID="ddlAAACode"
DataTextField="Description" DataValueField="AAACode"
FolderStyle="~/AppThemes/intstyles/premiere_blue/OboutDropDownList"
Width="250" Enabled="true"
AutoPostBack="true"
OnSelectedIndexChanged="ddlAAACode_SelectedIndexChanged" />
“ddlAAACode_SelectedIndexChanged”代码
protected void ddlAAACode_SelectedIndexChanged(object sender, EventArgs e)
{
string AAACode = ddlAAACode.SelectedValue;
.....getting business object & entity.....
try
{
DataTable dt = obj.GetObject(AAACode);
if (dt != null)
{
if (dt.Rows.Count > 0)
{
grid1.DataSource = dt;
grid1.DataBind();
}
dt = null;
}
}
catch (ApplicationException ex)
{
throw new ApplicationException(ex.Message);
}
finally
{
}
}
从下拉列表中选择一项后,“Obout 网格”将根据需要正确检索数据,但随后完全冻结且无法正常工作(即使单击 Obout 网格上方的任何位置也不会发生任何事情)。下面是 UpdatePanel 中“关于网格”的示例代码。
<asp:UpdatePanel ID="UpdatePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<obout:Grid id="grid1" runat="server" CallbackMode="true" AllowPageSizeSelection="false" Serialize="false"
AutoGenerateColumns="false" FolderStyle="~/App_Themes/grdstyles/style_12" AllowFiltering="true"
AllowAddingRecords="false">
<Columns>
<obout:Column ID="Column1" DataField="AAACode" Width="100" HeaderText="AAA Code" runat="server">
<FilterOptions>
<obout:FilterOption Type="NoFilter" />
<obout:FilterOption Type="Contains" />
<obout:FilterOption Type="DoesNotContain" />
<obout:FilterOption Type="StartsWith" />
<obout:FilterOption Type="EndsWith" />
</FilterOptions>
</obout:Column>
<ContentTemplate>
........
........
........
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ddlGroupCode"/>
</Triggers>
</asp:UpdatePanel>
任何评论都非常感谢..帮助我.. :)
