请高手看看应该选择什么控件！立刻给分

[wwangzhihang100]

我现在需要在一个页面中大量的录入信息，但是录入信息的单位数量是不定的，就是需要动态生成。
不知道用什么控件合适。
我原来用了table+textbox，都是动态生成，但是当我第二次访问该页面时总是出现index error，控件的index出错。
怎么办呢？

[pingnt]

我以前也做过类似的东东,是用DATAGRID+TEXTBOX.

[kanshangren]

table+textbox应该可以的呀，具体错误信息是什么？

顶

[cuike519]

用DataGrid不行吗？你要求的是什么样的输入？？？

[「已注销」]

动态生成的控件可以用PlaceHolder控件，但是~~~~~~~
呵呵，还是比较麻烦，就象你碰见的情况，不容易保存状态

[zhpsam109]

DataGrid+TextBox应该可以把！

[codeangel]

do it inside

if(!PostBack)
{

}

[codeangel]

可以定义一个静态变量，
在Page_Lode里写入建立控件的数量
不要写在
if(!PostBack)
{

}
CreatedControls(控件数量)
里
public void CreatedControls(int count)
{
TextBox txt;
Button btn;
Label lbl;

TextBox txt1;
Button btn1;
Label lbl1;

for(int i=0;i<count;i++)
{
lbl=new Label();
txt=new TextBox();
btn=new Button();


lbl.ID ="lbl_"+(i+1).ToString();
lbl.Text="新增附件";
txt.ID = "txt_"+(i+1).ToString();
txt.Text=txt.ID;

btn.ID = "btn_"+(i+1).ToString();
btn.Text="浏览文件";

this.Panel1.Controls.Add(lbl);
this.Panel1.Controls.Add(txt);
this.Panel1.Controls.Add(btn);
btn.Click += new System.EventHandler(btn_Click);

lbl1=new Label();
txt1=new TextBox();
btn1=new Button();

lbl1.ID ="lbl1_"+(i+1).ToString();
lbl1.Text="附件标题";
txt1.ID = "txt1_"+(i+1).ToString();
btn1.ID = "btn1_"+(i+1).ToString();
btn1.Text="删除本条";

this.Panel1.Controls.Add(lbl1);
this.Panel1.Controls.Add(txt1);
this.Panel1.Controls.Add(btn1);
btn1.Click += new System.EventHandler(btn1_Click);


}

我也觉得可以，要不你生成动态的之后再跳转回来看看？

[goody9807]

可以用PlaceHolder控件

动态添加表格行

Function AddRow(ByVal i, ByVal tr1)

Dim td1 As New TableCell()
Dim td2 As New TableCell()
Table2.CellPadding = 0
Table2.CellSpacing = 0

tr1.BackColor = Color.LightGray

td1.HorizontalAlign = HorizontalAlign.Center
td2.HorizontalAlign = HorizontalAlign.Center
td1.VerticalAlign = VerticalAlign.Middle
td1.BorderColor = Color.Black
td2.BorderColor = Color.Black



td1.BorderWidth = Unit.Pixel(1)
td2.BorderWidth = Unit.Pixel(1)

Dim txtXx As New TextBox()
txtXx.Width = Unit.Pixel(50)
txtXx.ID = "xx" + i.ToString()


td1.Text = "option" + i.ToString()
td2.Controls.Add(txtXx)

tr1.Cells.Add(td1)
tr1.Cells.Add(td2)

Table2.Rows.Add(tr1)

End Function
Function addrow2(ByVal i)
Dim txtXx As New TextBox()
txtXx.Width = Unit.Pixel(10)
txtXx.ID = "xx" + i.ToString()
Page.Controls.Add(txtXx)
End Function
Function add3(ByVal tr As TableRow)
Dim txtXx As New TextBox()
txtXx.Width = Unit.Pixel(100)
txtXx.ID = "xx" + i.ToString()
txtXx.Text = "option" + i.ToString()

Dim td As New TableCell()
td.Controls.Add(txtXx)
tr.Cells.Add(td)
Table2.Rows.Add(tr)
End Function

Table tb=new Table();
try
{
tb.Attributes.Remove("style");
tb.Atrributes.Add("style","border-style:None;width:940px;word-break:break-all; word-wrap: break-word;");
}
catch(Exception ex)
{
throw(ex);
}

上面是我刚写的一个程序，与你的要求差不多！
不仅支持textbox，还支持dropdownlist,radiobuttonlist,当然还可以扩充。

程序支持多语言，自定字段等相关功能的代码未贴出，你参考其中添加控件部分的代码就可以啦。

出现的错误
Multiple controls with the same ID 'SpecProjectName_1' were found. FindControl requires that controls have unique IDs.
怎么使用datagrid+textbox?

[MSNETFANS]

DataGrid+TextBox可以的

[peering08cn]

DATAGRID+TEXTBOX
或者
Datalist + textbox
