如何从 GridView 检索文本框值

Question

I have a gridview and created dynamic TextBox in the RowDataBound event as我有一个gridview并在RowDataBound事件中创建了动态TextBox作为

TextBox txtbox = new TextBox();
txtbox.ID = "txt1";
txtControl.Text = "SoomeValue";

When I'm trying to retrieve the value on a button click as当我尝试检索button click上的值时， button click为

    TextBox textboxValue = (TextBox)gv.Rows[rowIndex].Cells[cellIndex].FindControl("txt1");
    string value = textboxValue.Text;

It is always returning null beside it is having the value它总是返回null除了它具有value

Answer is No. You cannot retrieve dynamically added TextBox from GridView like you are trying.答案是否定的。您无法像尝试一样从 GridView 中检索动态添加的 TextBox。

If you use GridView, you need to add textbox inside Template Column at Design Time .如果您使用 GridView，则需要在设计时在模板列中添加文本框。
