在运行时更改ButtonField(在Gridview中添加)的ImageURL. [英] Change the ImageURL of ButtonField(added in Gridview) at runtime..

问题描述

我在Gridview中添加了一个ButtonField，如..

Hi,

I added a ButtonField in the Gridview like..

<asp:GridView ID="GridView1" runat="server">
    <Columns>
        <asp:ButtonField ButtonType="Image" ImageUrl="ImagePath" />
    </Columns>
    </asp:GridView>

现在，如何在运行时在OnClick事件中更改ButtonField的URL?

Now How can i Change the URL of the ButtonField at runtime in OnClick Event??

推荐答案

<asp:ButtonField ButtonType="Image" ImageUrl="~/Images/pdf.png"  CommandName="pdf_click" ID="imgprint"/>

背后的代码

Code behind

void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
 {
 // If multiple buttons are used in a GridView control, use the
 // CommandName property to determine which button was clicked.
 if(e.CommandName=="pdf_click")
  {
   // Convert the row index stored in the CommandArgument
   // property to an Integer.
   int index = Convert.ToInt32(e.CommandArgument);

   // Retrieve the row that contains the button clicked
   // by the user from the Rows collection.
  ButtonField cf = (ButtonField)e.Row.FindControl("imgprint");
  cf.ImageUrl = "images/something.png";
   // Now you have access to the gridviewrow.
  }
}
