Telerik Rad Gridview设计未正确显示

我对RadGridView有一个简单的问题

标题列与行中的列不匹配。 贝娄，我添加了一个RadGridVew的图像。

以下是RadGridview的代码：

<telerik:RadGrid ID="RadGrid_othrexp" AllowSorting="true" runat="server"  OnUpdateCommand="RadGrid_othrexp_UpdateCommand"
            OnNeedDataSource="RadGrid_othrexp_NeedDataSource" AutoGenerateColumns="False">
            <ClientSettings>
                <Scrolling AllowScroll="True" UseStaticHeaders="True" ScrollHeight="375px" />
            </ClientSettings>
            <MasterTableView EnableColumnsViewState="false" DataKeyNames="ID" AutoGenerateColumns="false">
                <CommandItemSettings ExportToPdfText="Export to PDF" />

期待您的回复，谢谢。

只需将宽度添加到100%，如下所示。希望它能解决你的问题
