找到点击的图像按钮 [英] find clicked imagebutton

问题描述

嘿！
我的目录中有一些图片...

很好，当用户单击其中之一时，我希望幻灯片显示它！

            foreach (string hssi in HomeSlideShowImages)

                        imgbtnSlideShowPic.Height = 50;
                        imgbtnSlideShowPic.Width = 50;
                        imgbtnSlideShowPic.ImageUrl = @"..\Images\ImagesHome\" + strDirectories;

推荐答案

我建​​议您在生成ImageButton时设置ID.试试这个:

I would recommend you to set ID while generating the ImageButton. Try this:

int count = 0;
foreach (string strDirectories in strImageAdress)
{
    if (strDirectories.Contains('.'))
    {
        count ++; //Increase you count by one
        imgbtnSlideShowPic = new ImageButton();
        imgbtnSlideShowPic.AlternateText = @"..\Images\ImagesHome\" + strDirectories;
        imgbtnSlideShowPic.ID = "imgbtn"+count.ToString();
        //Here we have given ID to the button.
        imgbtnSlideShowPic.Height = 50;
        imgbtnSlideShowPic.Width = 50;
        imgbtnSlideShowPic.ImageUrl = @"..\Images\ImagesHome\" + strDirectories;
        pnlSlideShowController.Controls.Add(imgbtnSlideShowPic);

    imgbtnSlideShowPic.Click += new  ImageClickEventHandler(imgbtnSlideShowPic_Click);                     
    }
}
protected void imgbtnSlideShowPic_Click(object sender, EventArgs e)
{
    ImageButton img = (ImageButton)sender;
    string btn = img.ID;
    //write your code here
}

尝试:

protected void imgbtnSlideShowPic_Click(object sender, EventArgs e)
{
    ImageButton ib = (ImageButton)sender;
    string objSenderID = ib.ID;
    // you know the ID of the image button clicked!
    // Use the way you like!
}
