如何在 .NET 上的 Repeater 中一起查找选定的行和列索引

发布于 2024-11-14 16:35:06 字数 124 浏览 3 评论 0原文

我有一个中继器组件来显示数据。我可以使用 Repeater1.Items[e.Item.ItemIndex].ItemIndex.ToString() 获取行索引，但它只给我选定的行。我怎样才能找到列索引？

提前致谢，

Repeater 中没有行索引和列索引。只需使用 itemindex 就可以知道：

e.Item.ItemIndex

您不需要执行 Repeater1.Items[e.Item.ItemIndex].ItemIndex。

Repeater 控件用于显示绑定到该控件的重复项目列表。所以没有行或列。

There is no row and column index in repeater. Just itemindex which can be known using:

e.Item.ItemIndex

You don't need to do Repeater1.Items[e.Item.ItemIndex].ItemIndex.

The Repeater control is used to display a repeated list of items that are bound to the control. So there is no row or column.

为了获取对转发器中控件的引用，我使用 FindControl()，它获取分配给 id 属性的控件的名称。

Dim EmployeeRepeater as Repeater = CType(Me.Form.FindControl("EmployeeRepeater")
Dim EmployeeRepeaterItem as RepeaterItem
Dim EmployeeName as Textbox

For Each EmployeeRepeaterItem In EmployeeRepeater.Items
    Employeename = CType(EmployeeRepeaterItem.FindControl("EmployeenNameTextBox")
    'do something here with Employee Name
Next

To get a reference to a control within a repeater I use FindControl() which takes the name of the control that was assigned to the id attribute.

Dim EmployeeRepeater as Repeater = CType(Me.Form.FindControl("EmployeeRepeater")
Dim EmployeeRepeaterItem as RepeaterItem
Dim EmployeeName as Textbox

For Each EmployeeRepeaterItem In EmployeeRepeater.Items
    Employeename = CType(EmployeeRepeaterItem.FindControl("EmployeenNameTextBox")
    'do something here with Employee Name
Next

Button btn = sender as Button;
if (btn != null)
{
    RepeaterItem ri = btn.NamingContainer as RepeaterItem;
    if (ri != null)
        // use ri here as you see fit...  ri is a pointer to the item where the button was clicked.
}

Button btn = sender as Button;
if (btn != null)
{
    RepeaterItem ri = btn.NamingContainer as RepeaterItem;
    if (ri != null)
        // use ri here as you see fit...  ri is a pointer to the item where the button was clicked.
}
