代码背后的

on code behind

Image imag = ((Image)GridView1.FindControl("Image7"));

调试时显示Imag = null。

it showing Imag = null while debugging.

推荐答案

试试这样

Try like this

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        Image image = row.FindControl("Image7") as Image;
    }
}

protected void rg_ItemDataBound(object sender, GridItemEventArgs e)
        {

{

GridDataItem item =（GridDataItem）e.Item;

Image lblRate =（Image）item.FindControl（lblRate）;

这是如果你使用radgrid.You也可以尝试gridview。

}



或试试喜欢这个



foreach（rg.MasterTableView.Items中的GridDataItem项目）

{

RadNumericTextBox txtHoursBilled =（ RadNumericTextBox）item.FindControl（txtHoursBilled）;

Label lblTotal =（Label）item.FindControl（lbl1）;

Label lblRate =（Label）item。 FindControl（lbl2）;



}

{
GridDataItem item = (GridDataItem)e.Item;
Image lblRate = (Image)item.FindControl("lblRate");
This is If u r using radgrid.You can also try it for gridview.
}

or try like this

foreach (GridDataItem item in rg.MasterTableView.Items)
{
RadNumericTextBox txtHoursBilled = (RadNumericTextBox)item.FindControl("txtHoursBilled");
Label lblTotal = (Label)item.FindControl("lbl1");
Label lblRate = (Label)item.FindControl("lbl2");

}
