如何解决ASP.NET C＃使用ITemplate
我正在尝试制作一个更漂亮的秤。 ScreenShot 1 : Lickert Scale Example Image
问题1： 创建在文本框中输入的列数。 My Site Example ScreenShots#2列的名称从1到给定数字开始。单击由项目板创建的复选框不会触发。
问题2： 假设我们没有为触发复选框而烦恼。如何获得选中的复选框？即使我使用for浏览网格，也无法接收它。
My Site Example ScreenShots#2 注意：保存选择后，必须完成更新和删除过程。保存期间，它应该浏览网格并获得标记的复选框。

C＃：AddTemplateToGridView.cs
public class AddTemplateToGridView : ITemplate
{
ListItemType _type;
string _colName;
DataTable dt2;
int sayi = 0;
public AddTemplateToGridView(ListItemType type,string colname,DataTable dt)
{
_type = type;
_colName = colname;
dt2 = dt;
}
void ITemplate.InstantiateIn(System.Web.UI.Control container)
{
switch (_type)
{
case ListItemType.Item:
sayi++;
CheckBox checkbox = new CheckBox();
//checkbox.Attributes.Add("onclick","javascript:SingleCheckboxCheck(this)");
checkbox.EnableViewState = true;
checkbox.Enabled = true;
//checkbox.AutoPostBack = true;
checkbox.CheckedChanged += new EventHandler (this.Checkbox_CheckedChanged);
container.Controls.Add(checkbox);
break;
}
}
protected void Checkbox_CheckedChanged(object sender,EventArgs e)
{
CheckBox chk = (sender as CheckBox);
if (chk.Checked)
{
}
}
}
