Hello There:

I want to update the text property of my textbox control in Asp.Net from within loop.I have tried using Ajax updatepanel with the timer control but unable to update the text property.I have been searching this since last week but unable to find any answer any help would be higly appreciated :( :( :(

Thanks.

Code from OP, removed from answers.
Thanks all of you for the reply. Here is my code.This is my button click event in this code you can see I am updating the

TxtContent.Text

在循环中，文本由用户定义的函数
返回

within a loop the text is being returned by a user defined function called

ReturnBodyText()

之后，我将文本分配给viewstate，以便在计时器滴答事件中，我可以调用文本并更新文本框的text属性，然后在计时器滴答事件中，将viewstate值分配给文本框.

afterwards I am assigning the text to the viewstate so that at the timer tick event I can recall the text and update the textbox text property and then at the timer tick event assigning the viewstate values to the textbox.

protected void Button4_Click(object sender, EventArgs e)
{
    ArrayList FilePath = (ArrayList)ViewState["ArrayList"];
    int i = 0;
    int b = 1;
    foreach(string[] sr in FilePath)
    {
        string Month = sr[i];
        string datewithzero;
        datewithzero = String.Format("{0:00}", b);
        string[] FilesArray = (string[])listfiles(Month, datewithzero).ToArray(typeof(string));
 
        foreach (string FileNameWithExtension in FilesArray)
        {
            ListBox4.Items.Add(FileNameWithExtension);
            TxtContent.Text = ReturnBodyText(Month, datewithzero, FileNameWithExtension);
            ViewState["Content"] = TxtContent.Text;
            Timer1.Enabled = true;
            Timer1_Tick(ViewState["Content"], e);
        }
        i = i + 1;
        b = b + 1;
    }
}

protected void Timer1_Tick(object sender, EventArgs e)
{
    TxtContent.Text =(string) ViewState["Content"];
    TxtContent.DataBind();
}

希望以上描述能帮助您理解我的问题

谢谢. :)

推荐答案

尝试一下...

Try This..

 <form id="form1"  runat="server">
 <asp:ScriptManager ID="ScriptManager1" runat="server">
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <contenttemplate>
          <asp:TextBox ID="txtChangeValue" runat="server">
        </contenttemplate>
    
 <asp:Timer ID="Timer1" runat="server" Interval="500" ontick="Timer1_Tick">
 
</form>

在代码中

In Code

static int count = 0;
   protected void Timer1_Tick(object sender, EventArgs e)
   {
       txtChangeValue.Text = count.ToString();
       count += 1;
   }

与我们显示一些时钟或递增计数器相同.
尝试使用像Always Visible Control Extender这样的Ajax控件工具包的控件.

Its same as we display some clock or incrementing counter.
Try to use Ajax control toolkit''s control like Always Visible Control Extender.

在ASP.Net设计中使用更新面板
