解决方案

亲爱的Subhan，


中继器控件用于显示网格或列表等重复数据模式



例如：

http://www.w3schools.com/aspnet/aspnet_repeater.asp



和



msdn.microsoft.com/en-us/magazine/cc163780.aspx



我不确定你想通过添加一个文本框来实现什么目标，我建议创建项目模板，然后将数据绑定到那些项目模板。



希望这有帮助



问候

Omer。

  protected   void  ddldept_SelectedIndexChanged（ object  sender，Even tArgs e）
 {
  if （！IsPostBack）
 {
 DropDownList d =（DropDownList）sender; 
  //   TextBox t =（TextBox）sender;  
 
  int  index = Convert.ToInt32（d.SelectedValue）; 
 
  if （index ==  2 ）
 {
 TextBox tb = FindControl（  txtdriver） as  TextBox; 
 tb.text =   N / a; 
 TextBox tbl = FindControl（  txtlocation） as  TextBox; 
 tbl.Textt =   Yard; 
} 
} 
} 

你发现文本框错误的方式gioven错误你告诉

尝试在repeter的下拉项中运行此代码，使用当前选定的索引 ..



protected void ddldept_SelectedIndexChanged（object sender ，EventArgs e）

{

DropDownList d =（DropDownList）发送者;

// TextBox t =（TextBox）发送者;



int Value = Convert.ToInt32（d.SelectedValue）;

int index = d.TabIndex;

if（值== 2）

{

TextBox tb =（TextBox）Repeater1.Items [index] .FindControl（txtdriver）;

tb.Text =N / a;

TextBox tbl =（TextBox）Repeater1.Items [index] .FindControl（txtlocation）;

tbl.Text = Yard;

}

//在这里使用

}

Dear Subhan,

Repeater control is used to display repeating pattern of data like grid or lists

Examples:
http://www.w3schools.com/aspnet/aspnet_repeater.asp

and

msdn.microsoft.com/en-us/magazine/cc163780.aspx

I am not sure what do you want to achieve by adding a single text box to it, I suggest creating Item templates and then bind the data to those item templates.

Hope this helps

Regards
Omer.

protected void ddldept_SelectedIndexChanged(object sender, EventArgs e)
{
if(!IsPostBack)
    {
        DropDownList d = (DropDownList)sender;
         //TextBox t = (TextBox)sender;
                    
          int index = Convert.ToInt32(d.SelectedValue);
         
                    if (index == 2)
                    {
                        TextBox tb = FindControl("txtdriver") as TextBox;
                       tb.text ="N/a";
                        TextBox tbl = FindControl("txtlocation") as TextBox;
                        tbl.Textt = "Yard";
                    }
        }
}

You find the Textbox wrong way which gioven error as you told
Try to Run this code its working with your current selected index in repeter's dropdown items..

protected void ddldept_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList d = (DropDownList)sender;
//TextBox t = (TextBox)sender;

int Value = Convert.ToInt32(d.SelectedValue);
int index = d.TabIndex;
if (Value == 2)
{
TextBox tb = (TextBox)Repeater1.Items[index].FindControl("txtdriver");
tb.Text = "N/a";
TextBox tbl = (TextBox)Repeater1.Items[index].FindControl("txtlocation");
tbl.Text = "Yard";
}
// Use d here
}
