如何将行添加到 TableLayoutPanel 的中间

发布于 2024-12-13 10:18:54 字数 1408 浏览 1 评论 0原文

我有一个 3 列 1 行的 TableLayoutPanel：（“删除”按钮、“用户控件”、“添加”按钮）

我希望“添加”按钮在单击的按钮下方添加类似于上面的新行：例如：之前：（

删除按钮 1、用户控制 2、添加按钮 1）
（删除按钮 2、用户控制 2、添加按钮 2）

单击“添加按钮 1”后：（

删除按钮 1、用户控制 2、添加按钮 1）
（删除按钮 3、用户控件 3、添加按钮 3）
（删除按钮 2、用户控件 2、添加按钮 2）

我设法将该行添加到 tablelayoutpanel 的末尾，但没有添加到中间：它不断搞乱布局。这是事件处理程序的片段：

void MySecondControl::buttonAdd_Click( System::Object^ sender, System::EventArgs^ e )
{
   int rowIndex = 1 + this->tableLayoutPanel->GetRow((Control^)sender);

   /* Remove button */
   Button^ buttonRemove = gcnew Button();
   buttonRemove->Text = "Remove";
   buttonRemove->Click += gcnew System::EventHandler(this, &MySecondControl::buttonRemove_Click);

   /* Add button */
   Button^ buttonAdd = gcnew Button();
   buttonAdd->Text = "Add";
   buttonAdd->Click += gcnew System::EventHandler(this, &MySecondControl::buttonAdd_Click);

   /*Custom user control */
   MyControl^ myControl = gcnew MyControl();

   /* Add the controls to the Panel. */
   this->tableLayoutPanel->RowCount += 1;
   this->tableLayoutPanel->Controls->Add(buttonRemove, 0, rowIndex);
   this->tableLayoutPanel->Controls->Add(myControl, 1, rowIndex);
   this->tableLayoutPanel->Controls->Add(buttonAdd, 2, rowIndex);
}

这不能正常工作。

我做错了什么吗？有什么建议吗？

I have a TableLayoutPanel with 3 columns and 1 row:
(Remove button, User Control, Add button)

I want the Add button to add a new row similar to the above below the clicked button:
e.g:
BEFORE:

(Remove button 1, User Control 2, Add button 1)
(Remove button 2, User Control 2, Add button 2)

After clicking"Add button 1":

(Remove button 1, User Control 2, Add button 1)
(Remove button 3, User Control 3, Add button 3)
(Remove button 2, User Control 2, Add button 2)

I managed to add the row to the end of the tablelayoupanel but not to the middle: It keeps screwing up the layout.
Here's a snippet of the event handler:

void MySecondControl::buttonAdd_Click( System::Object^ sender, System::EventArgs^ e )
{
   int rowIndex = 1 + this->tableLayoutPanel->GetRow((Control^)sender);

   /* Remove button */
   Button^ buttonRemove = gcnew Button();
   buttonRemove->Text = "Remove";
   buttonRemove->Click += gcnew System::EventHandler(this, &MySecondControl::buttonRemove_Click);

   /* Add button */
   Button^ buttonAdd = gcnew Button();
   buttonAdd->Text = "Add";
   buttonAdd->Click += gcnew System::EventHandler(this, &MySecondControl::buttonAdd_Click);

   /*Custom user control */
   MyControl^ myControl = gcnew MyControl();

   /* Add the controls to the Panel. */
   this->tableLayoutPanel->RowCount += 1;
   this->tableLayoutPanel->Controls->Add(buttonRemove, 0, rowIndex);
   this->tableLayoutPanel->Controls->Add(myControl, 1, rowIndex);
   this->tableLayoutPanel->Controls->Add(buttonAdd, 2, rowIndex);
}

This doesn't work properly.

Am I doing something wrong? any suggestions?

终于找到了解决方案：我没有将控件添加到直接位置，而是将它们添加到末尾，然后使用 SetChildIndex() 函数将控件移动到所需位置：

void MySecondControl::buttonAdd_Click( System::Object^ sender, System::EventArgs^ e )
{
   int childIndex = 1 + this->tableLayoutPanel->Controls->GetChildIndex((Control^)sender);

   /* Remove button */
   Button^ buttonRemove = gcnew Button();
   buttonRemove->Text = "Remove";
   buttonRemove->Click += gcnew System::EventHandler(this, &MySecondControl::buttonRemove_Click);

   /* Add button */
   Button^ buttonAdd = gcnew Button();
   buttonAdd->Text = "Add";
   buttonAdd->Click += gcnew System::EventHandler(this, &MySecondControl::buttonAdd_Click);

   /*Custom user control */
   MyControl^ myControl = gcnew MyControl();

   /* Add the controls to the Panel. */
   this->tableLayoutPanel->Controls->Add(buttonRemove);
   this->tableLayoutPanel->Controls->Add(myControl);
   this->tableLayoutPanel->Controls->Add(buttonAdd);

   /* Move the controls to the desired location */
   this->tableLayoutPanel->Controls->SetChildIndex(buttonRemove, childIndex);
   this->tableLayoutPanel->Controls->SetChildIndex(myControl, childIndex + 1);
   this->tableLayoutPanel->Controls->SetChildIndex(buttonAdd, childIndex + 2);
}

Finally found a solution: Instead of adding the controls to thier direct location, I'm adding them to the end and then use the SetChildIndex() function to move the control to the desired location:

void MySecondControl::buttonAdd_Click( System::Object^ sender, System::EventArgs^ e )
{
   int childIndex = 1 + this->tableLayoutPanel->Controls->GetChildIndex((Control^)sender);

   /* Remove button */
   Button^ buttonRemove = gcnew Button();
   buttonRemove->Text = "Remove";
   buttonRemove->Click += gcnew System::EventHandler(this, &MySecondControl::buttonRemove_Click);

   /* Add button */
   Button^ buttonAdd = gcnew Button();
   buttonAdd->Text = "Add";
   buttonAdd->Click += gcnew System::EventHandler(this, &MySecondControl::buttonAdd_Click);

   /*Custom user control */
   MyControl^ myControl = gcnew MyControl();

   /* Add the controls to the Panel. */
   this->tableLayoutPanel->Controls->Add(buttonRemove);
   this->tableLayoutPanel->Controls->Add(myControl);
   this->tableLayoutPanel->Controls->Add(buttonAdd);

   /* Move the controls to the desired location */
   this->tableLayoutPanel->Controls->SetChildIndex(buttonRemove, childIndex);
   this->tableLayoutPanel->Controls->SetChildIndex(myControl, childIndex + 1);
   this->tableLayoutPanel->Controls->SetChildIndex(buttonAdd, childIndex + 2);
}
