Asp.net 基于其他RadGrid PageSize更改Telerik RadGrid PageSize

在我的页面RadGrid1和RadGrid2中有两个RadGrid控件，当我更改其中任何一个控件的页面大小时，我希望另一个控件以相同的页面大小自动更改，我尝试了以下方法：

protected void RadGrid1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    RadGrid2.PageSize = e.NewPageSize;
}

protected void RadGrid2_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    RadGrid1.PageSize = e.NewPageSize;
}

但这会导致stackoverflow异常，因为每个事件都调用另一个事件。

请使用下面的代码片段进行尝试

.aspx

 <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" OnItemDataBound="RadGrid1_ItemDataBound"
    OnNeedDataSource="RadGrid1_NeedDataSource" AllowFilteringByColumn="true" 
     PageSize="2" AllowPaging="true" onpagesizechanged="RadGrid1_PageSizeChanged">
    <MasterTableView Name="Parent" DataKeyNames="ID" EditMode="PopUp">
        <Columns>
            <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name">
            </telerik:GridBoundColumn>
            <telerik:GridEditCommandColumn>
            </telerik:GridEditCommandColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

<telerik:RadGrid ID="RadGrid2" runat="server" AutoGenerateColumns="False" OnNeedDataSource="RadGrid2_NeedDataSource"  onpagesizechanged="RadGrid2_PageSizeChanged"
PageSize="2" AllowPaging="true">
    <MasterTableView Name="Parent" DataKeyNames="ID" EditMode="PopUp">
        <Columns>
            <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name">
            </telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

这将更改另一个网格的页面索引，我要求的是页面大小而不是索引。Jayesh我想要更改任何网格页面大小，而另一个网格采用相同的页面大小。您的代码将只从一侧生成“如果我更改RadGrid1页面大小，RadGrid2将更改，但如果我更改Grid2页面大小，将不会发生任何事情！！：）Jayesh如果你回顾了我所做的，你会发现除了重新绑定外，它与你的答案非常相似，Jayesh请尝试以下代码并告诉我你发现了什么。更改页面大小后，我们必须重新绑定网格。（意味着我们必须将数据源分配给网格）。如果我们在RadGrid1中更改大小，那么它将使用needdatasource事件自动重新绑定/分配数据源，对于RadGrid2，我们必须手动处理这件事。请查看下面的链接

 protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    dynamic data = new[] {
    new { ID = 1, Name ="Name1",path="1.jpg"},
    new { ID = 2, Name = "Name2",path="2.jpg"},
    new { ID = 3, Name = "Name3",path="3.jpg"},
     new { ID = 4, Name = "Name4",path="2.jpg"},
    new { ID = 5, Name = "Name5",path="3.jpg"}
};
    RadGrid1.DataSource = data;
}


protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode && e.Item is GridEditableItem)
    {
        GridEditableItem item = e.Item as GridEditableItem;
        string strID = item.GetDataKeyValue("ID").ToString();
        // Access your DataKey here
    }
}



protected void RadGrid2_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    dynamic data = new[] {
    new { ID = 1, Name ="Name1",path="1.jpg"},
    new { ID = 2, Name = "Name2",path="2.jpg"},
    new { ID = 3, Name = "Name3",path="3.jpg"},
     new { ID = 4, Name = "Name4",path="2.jpg"},
    new { ID = 5, Name = "Name5",path="3.jpg"}
};
    RadGrid2.DataSource = data;
}


protected void RadGrid1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    RadGrid2.PageSize = e.NewPageSize;
    RadGrid2.Rebind();
}

protected void RadGrid2_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    RadGrid1.PageSize = e.NewPageSize;
    RadGrid1.Rebind();
}
