selectedindexchanged没有开火 [英] selectedindexchanged not firing

问题描述

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (DropDownList1.SelectedValue == "Installment")
        {
            RadioButtonList1.Visible = true;
            Label11.Visible = true;
            txtInsAmount.Visible = true;
        }
    }

这段代码有什么问题？它没有开火。下拉列表位于modalpopupextender中。它应该显示这3项

whats wrong in this code? It is not firing. The dropdownlist is inside a modalpopupextender. It is supposed to show this 3 items

RadioButtonList1.Visible = true;
           Label11.Visible = true;
           txtInsAmount.Visible = true;

我不能设置自动回发为true，因为它会使modalpopupextender消失。

I cant set the auto postback to true because it will make the modalpopupextender disapper.

推荐答案

将auto post back属性设置为true。 &在选定的索引更改事件中再次显示使用'show'方法弹出相同的模型

Set auto post back property to true. & in selected index changed event again show same model pop up using 'show' method
