在Winform C＃.net应用程序中更改动态添加的控件的值，以及如何跟踪动态添加的控件 [英] Change values of dynamically added controls in winform c#.net application, how to track dynamically added controls

问题描述

我在运行时动态地在tableLayoutpanel的行内添加了控件，添加的控件是标签，LINKLABEL和图片框。

I have added controls dynamically on runtime inside the rows of a tableLayoutpanel , the controls added are LABELS, LINKLABEL AND A PICTURE BOX.

现在，我想在单击按钮时将这些动态添加的控件（标签，链接标签）的值（文本属性）更改为某些指定值。

Now , i want to change the value(Text Property) of these dynamically added controls(Labels, Linklabels) to some specified value, on a button click.

我该怎么做？请帮助提供代码。

How do i do this? Please help with code.

这些动态控件是否具有某种ID，例如HTML中的ID。

Is there some kind of ID for these dynamically controls like we have in HTML.

此外，我正在尝试使用此功能，但徒劳无功...........

Also , am trying to use this but all in vain...........

Control[] GettableLayoutPanelControls = new Control[11];

          GettableLayoutPanelControls =  tableLayoutPanel1.Controls.Find("Control Name", true) ;

             GettableLayoutPanelControls.SetValue("CHANGED VALUE ", 0); //this line gives error..........

推荐答案

尝试类似的操作，这将添加11个新的文本框（或您想要的任何其他控件）：

Try something like this, which will add 11 new text boxes (or any other control you want):

int NumberOfTextBoxes = 11;
TextBox[] DynamicTextBoxes = new TextBox[NumberOfTextBoxes];
int ndx = 0;

while (ndx < NumberOfTextBoxes) 
{
    DynamicTextBoxes[ndx] = new TextBox();
    DynamicTextBoxes[ndx].Name = "TextBox" + ndx.ToString();
    // You can set TextBox value here:
    // DynamicTextBoxes[ndx].Text = "My Value";
    tableLayoutPanel1.Controls.Add(DynamicTextBoxes[ndx]);
    ndx++;
}

这将动态地将文本框添加到TableLayout控件中。如果以后需要修改它们，则：

This will dynamically add Text Boxes to your TableLayout control. If you need to retreive them later:

foreach (Control c in TableLayoutPanel1.Controls)
{
    if (c is TextBox)
    {
        TextBox TextBoxControl = (TextBox)c;

        // This will modify the value of the 3rd text box we added
        if (TextBoxControl.Name.Equals("TextBox3"))      
            TextBoxControl.Text = "My Value";
    }
}
