我知道这是一个很好的问题,我发现一些标记为答案,但这些并不能解决我的问题。请看我的代码..
显示动态控件的方法
private void ShowControlsByFormId()
{
List<FormControlsBO> list = new List<FormControlsBO>();
list = new FormControlsDA().FormControls_GetByFormId(Convert.ToInt32(ddlForm.SelectedValue.ToString()));
if (list.Count > 0)
{
for (int i = 0; i < list.Count; i++)
{
DynamicControl dynamicControl = CommonUtility.GenerateControl(list[i]);
pnlInput.Controls.Add(new LiteralControl("<tr><td>"));
pnlInput.Controls.Add(dynamicControl.GeneratedControlLiteral);
pnlInput.Controls.Add(new LiteralControl("</td><td></td><td>"));
pnlInput.Controls.Add(dynamicControl.GeneratedControl);
pnlInput.Controls.Add(new LiteralControl("</td><tr><br/><br/>"));
}
pnlAction.Visible = true;
}
else
{
pnlAction.Visible = false;
}
}
生成动态控件的方法
public static DynamicControl GenerateControl(FormControlsBO bo)
{
DynamicControl dynamicControl = new DynamicControl();
Control control = new Control();
LiteralControl literal = new LiteralControl();
switch (bo.FieldType)
{
case "TextBox":
control = new TextBox();
control.ID = bo.FieldName;
literal.Text = bo.FieldLabel;
break;
case "RadioButton":
control = new RadioButton();
control.ID = bo.FieldName;
literal.Text = bo.FieldLabel;
break;
case "CheckBox":
control = new CheckBox();
control.ID = bo.FieldName;
literal.Text = bo.FieldLabel;
break;
case "DropDownList":
control = new DropDownList();
control.ID = bo.FieldName;
literal.Text = bo.FieldLabel;
break;
}
control.ClientIDMode = ClientIDMode.Static;
dynamicControl.GeneratedControl = control;
dynamicControl.GeneratedControlLiteral = literal;
return dynamicControl;
}
保存数据的方法
private void FormRecords_Save()
{
List<FormControlsBO> list = new List<FormControlsBO>();
FormControlsBO bo = new FormControlsBO();
foreach (Control ctl in pnlInput.Controls)
{
CommonUtility.DataFiller(bo, ctl);
list.Add(bo);
}
Boolean result = false;
result = new FormControlsDA().FormRecords_Save(list);
if(result == true)
{
lblMessage.Text = "Form data saved successfully";
}
else
{
lblMessage.Text = "Form data not saved";
}
}
问题是,当我调试代码时,pnlInput.Controls
显示零计数。请帮忙 !!
