Telerik的radgrid控件在编辑模式下设置绑定列到只读 [英] Telerik RadGrid set BoundColumn to ReadOnly in Edit Mode

问题描述

我有一个Telerik的radgrid控件具有三个绑定列和一个按钮列。我想，让用户只在绑定列的一个编辑值。用户可以添加一个新的记录，所以我不能设置两个绑定列只读。反正我有可以在ASPX做到这一点还是我必须这样做，在后面的代码？我有一些代码，是工作，但它是不是最好的。

下面是我的代码：

<预类=朗动prettyprint-覆盖> 案例编辑
昏暗aoeAnswerCode作为GridBoundColumn = CTYPE（e.Item.OwnerTableView.GetColumn（aoeAnswerCode），GridBoundColumn）
aoeAnswerCode。只读= TRUE

案更新，PerformInsert
。对于每一列的GridColumn在e.Item.OwnerTableView.RenderColumns
如果TypeOf运算列是IGridEditableColumn或者column.UniqueName = aoeAnswerCode然后


解决方案

只需将只读属性真正。请参见下面的例子：

 < Telerik的：GridBoundColumn数据字段=日期时间的HeaderText =日期
 DataFormatString = {0：MM / DD / YYYY}只读=真> 
< / Telerik的：GridBoundColumn> 
  

I have a Telerik RadGrid that has three bound columns and one button column. I would like to let the user edit the values in only one of the bound columns. The user can add a new record so i can't set the two bound column to read only. Is there anyway i can do this in the ASPX or do i have to do it in the code behind? I have some code that is working but it is not the best.

Here's my code:

Case "Edit"
    Dim aoeAnswerCode As GridBoundColumn = CType(e.Item.OwnerTableView.GetColumn("aoeAnswerCode"), GridBoundColumn)
    aoeAnswerCode.ReadOnly = True

Case "Update", "PerformInsert"
    For Each column As GridColumn In e.Item.OwnerTableView.RenderColumns
        If TypeOf column Is IGridEditableColumn Or column.UniqueName = "aoeAnswerCode" Then

解决方案

Simply set the ReadOnly property to true. See the example below:

<telerik:GridBoundColumn DataField="Datetime" HeaderText="Date" 
 DataFormatString="{0:MM/dd/yyyy}" ReadOnly="True">  
</telerik:GridBoundColumn>
