已禁用flowLayoutPanel中的复选框

Question

我正试图在flowLayoutPanel控件中动态创建一些复选框。

我已经设法创建了它，但它们在面板内似乎被禁用了。我无法选中/取消选中它们。它们是灰色的，不活跃。

我想有一些flowLayoutPanel属性阻止启用我缺少的这些复选框。

以下是flowLayoutPanel:的代码

// 
// flowLayoutPanelForCheckBoxes
// 
this.flowLayoutPanelForCheckBoxes.Controls.Add(this.SomeCheckBox);
this.flowLayoutPanelForCheckBoxes.AutoScroll = true;
this.flowLayoutPanelForCheckBoxes.Location = new System.Drawing.Point(132, 8);
this.flowLayoutPanelForCheckBoxes.Name = "flowLayoutPanelForCheckBoxes";
this.flowLayoutPanelForCheckBoxes.Size = new System.Drawing.Size(546, 38);
this.flowLayoutPanelForCheckBoxes.TabIndex = 28;
this.flowLayoutPanelForCheckBoxes.WrapContents = false;

用于生成复选框：

private List<CheckBox> GetGeneratedCheckboxes()
{
var generatedCheckboxes = new List<CheckBox>();
var valuesForCheckboxes = GetCheckboxValuesFromDb(); //it returns dictionary<int, string> 
// with some numbers and text. I think this method is not as important
if (valuesForCheckboxes != null && valuesForCheckboxes.Count != 0)
{
int index = 0;
foreach (var chbx in valuesForCheckboxes)
{
var checkboxToAdd = new System.Windows.Forms.CheckBox();
checkboxToAdd.AutoSize = true;
checkboxToAdd.Enabled = true;
checkboxToAdd.Checked = true;
checkboxToAdd.CheckState = System.Windows.Forms.CheckState.Checked;
checkboxToAdd.Size = new System.Drawing.Size(84, 21);
checkboxToAdd.UseVisualStyleBackColor = true;
checkboxToAdd.Name = "chboxCountry" + chbx.Key;
checkboxToAdd.Text = chbx.Value;
checkboxToAdd.TabIndex = index + 1;
index++;
generatedCheckboxes.Add(checkboxToAdd);
}
}
return generatedCheckboxes;
}

它用于FormLoad方法：

var checkboxesForPanel = GetGeneratedCheckboxes();
foreach (var checkbox in checkboxesForPanel)
{
this.flowLayoutPanelForCheckBoxes.Controls.Add(checkbox);
}

代码对我来说很好。它没有问题。检查您的流程布局面板是否处于禁用状态。签入设计器，或者如果代码处于禁用状态，请检查代码。
