How Do I pass Values into an imagebutton click event in c#?
提问by Roger Walsh
Trying to pass some values into an imagebutton click event, something like this:
尝试将一些值传递给 imagebutton 单击事件，如下所示：
<asp:ImageButton id="imagebutton1" runat="server" AlternateText="5 Star Luxury Villas in North Cyprus" ImageUrl="/download/1/luxury_villas.jpg" OnClick="ImageButton_Click('value1', 'value2')"/>
then in code behind:
然后在后面的代码中：
protected void ImageButton_Click(object sender, ImageClickEventArgs e, string value1, string value2)
{
Response.Write(Value2);
}
采纳答案by Eoin Campbell
Try using OnCommandinstead of OnClick
尝试使用OnCommand代替OnClick
Then you can specify values in the CommandName& CommandArgumentProperties
然后您可以在CommandName&CommandArgument属性中指定值
<asp:ImageButton ID="blah" runat="server" OnCommand="blah_command" CommandName="val1" CommandArgument="val2,val3,val4" />
And
和
protected void blah_Command(object sender, CommandEventArgs e)
{
string val1 = e.CommandName.ToString();
string [] othervals = e.CommandArgument.ToString().Split(',');
}
