推荐答案

试试这个

Try this

Button b = new Button();
            b.Name = "Some Name";
            b.Text = "Button Text";
            //other setup here
            listView1.Controls.Add( b );

protected void lstviewcat_ItemCommand（object sender，ListViewCommandEventArgs e）

{

if（e.Item .ItemType == ListViewItemType.DataItem）

{

LinkBut​​ton linkBtnSubCat =（LinkBut​​ton）e.Item.FindControl（linkBtnSubCat）;

// int catid =（int）lstviewcat.DataKeys [e.Item.DataItemIndex] .Value;

// string catid = linkBtnSubCat.CommandArgument;

int catid = Convert .ToInt32（linkBtnSubCat.CommandArgument）;

// SubCat_Click（catid）;

ListView SubCategory =（ListView）e.Item.FindControl（SubCategory）;

SubCategory.DataSource = balObj.Getsubcat（catid）;

SubC ategory.DataBind（）;

LinkBut​​ton linkbtnsubcat = new LinkBut​​ton（）;

SubCategory.Controls.Add（linkbtnsubcat）;



if（SubCategory.HasControls（））

{

// linkbtnsubcat.Visible = true;

// linkbtnsubcat。 Style.Value =ADD;

linkbtnsubcat.Text =ADD SUB-CATEGORY;

//linkbtnsubcat.Width = 100;

linkbtnsubcat.Enabled = true;

//linkbtnsubcat.OnClientClick =add_new_subcat.aspx;

linkbtnsubcat.PostBackUrl =add_new_subcat.aspx;



}

}



}



这里balobj意味着我有一个单独的班级......

protected void lstviewcat_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
LinkButton linkBtnSubCat = (LinkButton)e.Item.FindControl("linkBtnSubCat");
//int catid = (int)lstviewcat.DataKeys[e.Item.DataItemIndex].Value;
//string catid = linkBtnSubCat.CommandArgument;
int catid = Convert.ToInt32(linkBtnSubCat.CommandArgument);
// SubCat_Click(catid);
ListView SubCategory = (ListView)e.Item.FindControl("SubCategory");
SubCategory.DataSource = balObj.Getsubcat(catid);
SubCategory.DataBind();
LinkButton linkbtnsubcat = new LinkButton();
SubCategory.Controls.Add(linkbtnsubcat);

if (SubCategory.HasControls())
{
// linkbtnsubcat.Visible = true;
// linkbtnsubcat.Style.Value = "ADD";
linkbtnsubcat.Text = "ADD SUB-CATEGORY";
//linkbtnsubcat.Width = 100;
linkbtnsubcat.Enabled = true;
//linkbtnsubcat.OnClientClick = "add_new_subcat.aspx";
linkbtnsubcat.PostBackUrl = "add_new_subcat.aspx";

}
}

}

here balobj means i have a separate class...
