禁用按钮，然后启用 [英] disable button and then enable

问题描述

我已经用excel和pdf生成报告
所以我用了2 btn

单击时，excel btn报告将在excel中生成
然后单击pdf生成的pdf btn报告

在某些情况下，单击生成的btn excel或btn pdf报告，但如果用户单击两次btn excel或两次btn pdf应用程序挂起，则需要花费更多时间

所以我想要的是

单击btn excel或btn pdf时，都将btn禁用，直到在excel中生成报告，或者在生成报告后单击pdf，然后都启用btn.

so what i want is

on click btn excel or btn pdf both btn disable till report generated in excel or in pdf after report generated then both btn enable .

推荐答案

用于按钮的启用/禁用目的您可以将btn.Enabled属性用作-

btn.Enabled = false(用于禁用按钮控件)

btn.Enabled = true(用于启用按钮控件)

for Enable/Disable purpose of button you can use : btn.Enabled property as -

btn.Enabled = false (For disabling button control)

btn.Enabled = true(For Enabling button control)

在两个Button事件上均单击OnClick只是将可见性设置为false.
如

OnClick on both Button events just set the visibility to false..

as

excelBtn.Visible=false;
pdfBtn.Visible=false;

在两个按钮单击事件中都使用这两行.

Use these two lines in both of your button click events.

输入
onlick excel方法
excelbtn.visible = false
onclick pdf方法
pdfbtn.visible = false

put
onlick excel method
excelbtn.visible=false
onclick pdf method
pdfbtn.visible=false
