向 ListViewWebpart 的每一行添加一个复选框

发布于 2024-11-07 17:35:22 字数 1624 浏览 0 评论 0原文

我正在开发一个 WSS 3 站点，该站点有一个显示各种列的 ListViewWebpart。

我需要向每一行添加一个复选框，并向标题添加一个按钮，该按钮将为所选行执行服务器端操作。

我是否需要制作自己的自定义 Web 部件，或者 ListViewWebpart 是否支持复选框？

向每一行添加复选框

我发现了一篇文章 ListViewWebpart 中的复选框这表明

...添加复选框，选择多个 listitem，在自定义列表中，声明如下所示的 xml 字符串。

<Field Type="Computed" ReadOnly="TRUE" Name="ListItemSelection" DisplayName="Select" Sortable="FALSE" Filterable="FALSE" EnableLookup="FALSE" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="ListItemSelection">
<FieldRefs>
<FieldRef Name="ID" />
</FieldRefs>
<DisplayPattern>
<HTML><![CDATA[<input type="checkbox" ]]></HTML>
<HTML><![CDATA[LItemId="]]></HTML>
<Column Name="ID" HTMLEncode="TRUE" />
<HTML><![CDATA["/> ]]></HTML>
</DisplayPattern>
</Field>

并致电 list.Fields。AddFieldAsXml (“xml 细绳”）;。将此作为第一个自定义列表视图中的列。

我假设后一部分需要 SPList。例如，

SPList list = SPContext.Current.Web.Lists["MyList"];
list.Fields.AddFieldAsXml(stringWithXmlFieldDefinition);

向标题行添加按钮

标题按钮的一个选项是自定义操作。这应该在工具栏中创建一个按钮。

I'm working on a WSS 3 site that has a ListViewWebpart displaying various columns.

I need to add a checkbox to each row and a button to the header that will perform a server side action for the selected rows.

Do I need to make my own custom webpart or can the ListViewWebpart support checkboxes?

Adding checkboxes to each row

I've found a post Checkbox in ListViewWebpart which suggests

...to add a checkbox, to select multiple
listitem, in the custom list, declare
a xml string as follows.

<Field Type="Computed" ReadOnly="TRUE" Name="ListItemSelection" DisplayName="Select" Sortable="FALSE" Filterable="FALSE" EnableLookup="FALSE" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="ListItemSelection">
<FieldRefs>
<FieldRef Name="ID" />
</FieldRefs>
<DisplayPattern>
<HTML><![CDATA[<input type="checkbox" ]]></HTML>
<HTML><![CDATA[LItemId="]]></HTML>
<Column Name="ID" HTMLEncode="TRUE" />
<HTML><![CDATA["/> ]]></HTML>
</DisplayPattern>
</Field>

and call the
list.Fields.AddFieldAsXml(“xml
string”);. Include this as a first
column in your custom list’s view.

I'm assuming the latter part requires a SPList. E.g.

SPList list = SPContext.Current.Web.Lists["MyList"];
list.Fields.AddFieldAsXml(stringWithXmlFieldDefinition);

Adding a button to the header row

One option for the header button is a CustomAction. This should create a button in the toolbar.

这是一个帖子，用于创建自定义 Web 部件，然后您可以使用您找到的帖子向自定义 Web 部件添加复选框（ListViewWebpart 中的复选框）。

请注意，list.Fields.AddFieldAsXml(stringWithXmlFieldDefinition); 最终可能会向您的共享点添加许多重复的复选框。重复项可以从数据库中删除，并位于 AllLists 表的 tp_Fields 列中。

要找到正确的字段，您可以通过列表 GUI 进行搜索。

declare @xmlString as xml
Select  @xmlString = tp_Fields
From        [WSS_Content].[dbo].[AllLists]
Where   tp_id ='xxxx'
Select @xmlString

然后，更新字段

declare @string as varchar(max)
set @string ='new value without duplicated checkbox'
UPDATE [WSS Content] . [dbo] . [AlILists)
SET [tp_Fields] = @string
WHERE tp_ID = 'xxx'

您可以简单地添加一个按钮

ToolBarButton newbtn = (ToolBarButton)Page.LoadControl("~/_CONTROLTEMPLATES/ToolBarButton.ascx");

，但可能您需要创建另一个工具栏来保存该按钮，您甚至可以创建自己的工具栏。您只需将其放入 C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\CONTROLTEMPLATES\YourCutomToolBar.ascx

Here is a post to create a custom web part, then you can add a check box to your custom web part using the post you have found (Checkbox in ListViewWebpart).

Be aware that,list.Fields.AddFieldAsXml(stringWithXmlFieldDefinition); can end up adding many duplicated check boxes to you sharepoint. The duplicated can be deleted from database and are located at AllLists table, tp_Fields column.

To find the right fields, you can search by the list guid.

declare @xmlString as xml
Select  @xmlString = tp_Fields
From        [WSS_Content].[dbo].[AllLists]
Where   tp_id ='xxxx'
Select @xmlString

then, update the fields

declare @string as varchar(max)
set @string ='new value without duplicated checkbox'
UPDATE [WSS Content] . [dbo] . [AlILists)
SET [tp_Fields] = @string
WHERE tp_ID = 'xxx'

You can simply add a button by

ToolBarButton newbtn = (ToolBarButton)Page.LoadControl("~/_CONTROLTEMPLATES/ToolBarButton.ascx");

but possibly you need create another toolbar to hold the button, you can even create your own toolbar. You just need to put it in C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\CONTROLTEMPLATES\YourCutomToolBar.ascx
