Radgrid FormTemplate 内的 Radcombobox

发布于 2024-10-03 01:47:20 字数 753 浏览 0 评论 0原文

天哪，

我在 RadGrid 中有一个 RadComboBox 控件，当 InitInsert 操作发生时会显示该控件。我使用实体框架作为数据源&其中包含的结果是正确的。我的问题是，当我使用 findcontrol 时它什么也不返回。

如果 e.CommandName = "InitInsert" 那么 RadGrid1.MasterTableView.InsertItemDisplay = Telerik.Web.UI.GridInsertItemDisplay.Bottom Dim query = From myTable In dbEntity.myTables Select myTable.Name, myTable.ID

        Dim mineCompBox = CType(e.Item.FindControl("mineCompBox"), RadComboBox)
        mineCompBox.DataSource = mineCompQuery
        mineCompRadBox.DataTextField = "Name"
        mineCompRadBox.DataValueField = "Id"
        mineCompRadBox.DataBind()</code>

我无法找到引用 FormTemplate 而不是编辑表单的任何答案。我缺少什么？：-（

谢谢。

G'day,

I have a RadComboBox control inside of a RadGrid that is displayed when the InitInsert action occurs. I'm using Entity Framework as a datasource & the results contained within this are correct. My problem is that when I use findcontrol it returns nothing.

If e.CommandName = "InitInsert" Then RadGrid1.MasterTableView.InsertItemDisplay = Telerik.Web.UI.GridInsertItemDisplay.Bottom Dim query = From myTable In dbEntity.myTables Select myTable.Name, myTable.ID

        Dim mineCompBox = CType(e.Item.FindControl("mineCompBox"), RadComboBox)
        mineCompBox.DataSource = mineCompQuery
        mineCompRadBox.DataTextField = "Name"
        mineCompRadBox.DataValueField = "Id"
        mineCompRadBox.DataBind()</code>

I'm having trouble finding any answers that reference FormTemplate without it being an edit form. What am I missing? :-(

Thanks.

我面前没有电脑来测试它，但我很确定：
1）你没有看到正确的控件集合
2) 或 RadComboBox 尚未创建或已创建但 ID 不匹配
所以你找不到它

，也不是100%确定。也许这可以帮助您它的完整示例： http:// /beecy.net/post/2009/01/07/telerik-radgrid-formtemplate-codebehind.aspx （也许可以根据此检查您的标记）

我的问题是通过使用 ItemCreated 命令解决的。可以在此处找到示例：

http://www.telerik.com/community/forums/aspnet-ajax/grid/find-controls-when-using-editcommand.aspx

我的情况的代码是：

Private Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated
    If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then
        Dim dbEntity As WebsiteEntities = New WebsiteEntities
        Dim myQuery = From myTable In myTables Select myTable.Name, myTable.ID
        Dim EditFormItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
        Dim myCombobox As RadComboBox = DirectCast(EditFormItem.FindControl("radDropBox"), RadComboBox)
        myCombobox.DataSource = myQuery
        myCombobox.DataTextField = "Name"
        myCombobox.DataValueField = "ID"
        myCombobox.DataBind()
    End If
End Sub

My problem was solved by using an ItemCreated command. An example can be found here:

http://www.telerik.com/community/forums/aspnet-ajax/grid/find-controls-when-using-editcommand.aspx

The code for my situation was:

Private Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated
    If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then
        Dim dbEntity As WebsiteEntities = New WebsiteEntities
        Dim myQuery = From myTable In myTables Select myTable.Name, myTable.ID
        Dim EditFormItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
        Dim myCombobox As RadComboBox = DirectCast(EditFormItem.FindControl("radDropBox"), RadComboBox)
        myCombobox.DataSource = myQuery
        myCombobox.DataTextField = "Name"
        myCombobox.DataValueField = "ID"
        myCombobox.DataBind()
    End If
End Sub
