动态创建控件后，它不允许单击 [英] After creating control dynamicly it does not allow click

问题描述

列表与LT;串GT; controlIdList = new List< string>（）; //在每个回发上存储控件ID

int counter = 0; // count组合框数

protected override void LoadViewState （对象保存状态）

{

base.LoadViewState（savedstate）;

controlIdList =（List< string>）ViewState [controlIdList] ;



foreach（controlIdList中的字符串id）

{

counter ++;

ASPxComboBox Cb = new ASPxComboBox（）;

Cb.ID = id;

Cb.DataSource = sdSku;

Cb.TextField = SkU;

Cb.ValueField =SkU;

Cb.ValueType = typeof（string）;

Cb.Columns.Add（ SKU）;

Cb.Columns.Add（Model）;

Cb.Columns.Add（Name）;

Cb.Attributes.Add（runat，server）;

Cb .DataBind（）;

LiteralControl lineBreak = new LiteralControl（
）;

PlaceholderSku.Controls.Add（Cb）;

PlaceholderSku.Controls.Add（lineBreak）;





}

}



protected void Page_Load（object sender，EventArgs e）

{



}

protected void btnAddSku_Click（object sender，EventArgs e）

{

counter ++;

ASPxComboBox Cb = new ASPxComboBox（）;

Cb.ID =SkuComboBox+计数器;





LiteralControl lineBreak = new LiteralControl（
）;

PlaceholderSku.Controls.Add（Cb）;

PlaceholderSku.Controls.Add（lineBreak）;

controlIdList.Add（ Cb.ID）;

ViewState [controlIdList] = controlIdList; //存储ids



}

List<string> controlIdList = new List<string>();//to store control Id on each postback
int counter = 0;//count Number of Comboboxes
protected override void LoadViewState(Object savedstate)
{
base.LoadViewState(savedstate);
controlIdList = (List<string>)ViewState["controlIdList"];

foreach( string id in controlIdList)
{
counter++;
ASPxComboBox Cb = new ASPxComboBox();
Cb.ID = id;
Cb.DataSource = sdSku;
Cb.TextField = "SkU";
Cb.ValueField = "SkU";
Cb.ValueType = typeof(string);
Cb.Columns.Add("SKU");
Cb.Columns.Add("Model");
Cb.Columns.Add("Name");
Cb.Attributes.Add("runat", "server");
Cb.DataBind();
LiteralControl lineBreak = new LiteralControl("
");
PlaceholderSku.Controls.Add(Cb);
PlaceholderSku.Controls.Add(lineBreak);


}
}

protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnAddSku_Click(object sender, EventArgs e)
{
counter++;
ASPxComboBox Cb = new ASPxComboBox();
Cb.ID = "SkuComboBox" + counter;


LiteralControl lineBreak = new LiteralControl("
");
PlaceholderSku.Controls.Add(Cb);
PlaceholderSku.Controls.Add(lineBreak);
controlIdList.Add(Cb.ID);
ViewState["controlIdList"] = controlIdList;//storing ids

}

推荐答案

创建对象时不添加点击处理程序：

You don't add a click handler when you create the object:

Cb.Attributes.Add("runat", "server");
Cb.DataBind();
Cb.Click += new EventHandler(btnAddSku_Click);

可能有帮助。
