在fo​​r循环中动态创建一个文本框 [英] Creating a Textbox dynamically in for loop

问题描述

我试图动态创建一个表，并把文本框在里面。在这里，在以下code，我试图创建一个文本框为每个K A不同的名称。但只有k的最后一个值是越来越显示在文本框中。我想知道我怎么可以给这样所有显示的名称为文本框。

 的for（int k = 0; K＆LT; tblCols; k ++）
{
    TableCell的TC =新的TableCell（）;
    文本框txtCompanyName =新的TextBox（）;
    txtCompanyName.Text = dsmissing.Tables [0] .Rows [tblCols- 1] [NewCompanyName]的ToString（）;
tc.Controls.Add（txtCompanyName）;
}
 

解决方案

替换该行

  dsmissing.Tables [0] .Rows [tblCols- 1] [NewCompanyName]的ToString（）;
 

通过

  dsmissing.Tables [0] .Rows [K] [NewCompanyName]的ToString（）;
 

我假设你像下面谈论ID。

 的for（int k = 0; K＆LT; tblCols; k ++）
{
    TableCell的TC =新的TableCell（）;
    文本框txtCompanyName =新的TextBox（）;
    。txtCompanyName.Text = dsmissing.Tables [0] .Rows [K] [NewCompanyName]的ToString（）;
    。txtCompanyName.ID = Guid.NewGuid（）的ToString（N）;
    tc.Controls.Add（txtCompanyName）;
}
 

I was trying to create a table dynamically and put textboxes in it. Here in the following code, i was trying to create a textbox with a distinct name for each k. But only the last value of k is getting displayed in the textbox. I was wondering how i could give a name to Textbox so all are shown.

for (int k = 0; k < tblCols; k++)
{
    TableCell tc = new TableCell(); 
    TextBox txtCompanyName = new TextBox();
    txtCompanyName.Text = dsmissing.Tables[0].Rows[tblCols- 1]["NewCompanyName"].ToString();
tc.Controls.Add(txtCompanyName);
}

解决方案

Replace this line

dsmissing.Tables[0].Rows[tblCols- 1]["NewCompanyName"].ToString();

With

dsmissing.Tables[0].Rows[k]["NewCompanyName"].ToString();

I assume you are talking about ID like below.

for (int k = 0; k < tblCols; k++)
{
    TableCell tc = new TableCell(); 
    TextBox txtCompanyName = new TextBox();
    txtCompanyName.Text = dsmissing.Tables[0].Rows[k]["NewCompanyName"].ToString();
    txtCompanyName.ID = Guid.NewGuid().ToString("N");
    tc.Controls.Add(txtCompanyName);
}
