如何在 ASPxGridView 中获取 EditTemplateItem？答案

【问题标题】：How to get EditTemplateItem in ASPxGridView?如何在 ASPxGridView 中获取 EditTemplateItem？

【问题描述】：

我在ASPxGridView 中的EditItemTemplate 中使用ASPxUploadControl。当我单击编辑行按钮时，会显示ASPxUploadControl，如果不是处于编辑模式，它会充当超链接列并显示下载文件选项。我面临的问题是我没有在ASPxGridView 的插入和更新事件中获取控制对象。

我正在做这样的事情

ASPxUploadControl = grid.FindEditRowCellTemplate(grid.Columns[0] as GridViewDataColumn, "upload_control_id") as ASPxUploadControl;

我也试过grid.FindControl()函数。

试试这个编辑Refer This

protected void ASPxUploadControl1_FilesUploadComplete(object sender, DevExpress.Web.ASPxUploadControl.FilesUploadCompleteEventArgs e){
    // Intentionally pauses server-side processing to demonstrate the Loading Panel or Progress Panel functionality
    System.Threading.Thread.Sleep(2000);

    ASPxUploadControl uploadControl = sender as ASPxUploadControl;

    if (uploadControl.UploadedFiles != null && uploadControl.UploadedFiles.Length > 0){
        for (int i = 0; i < uploadControl.UploadedFiles.Length; i++){
            UploadedFile file = uploadControl.UploadedFiles[i];
            if (file.FileName != ""){
                string fileName = string.Format("{0}{1}", MapPath("~/Images/"), file.FileName);
                //file.SaveAs(fileName, true);//OnLine Demo Restriction
            }
        }
    }
}

在更新或插入事件时，获取 GridView 以找到获取它的模板控件。

ASPxGridView gridView = sender as ASPxGridView;
ASPxUploadControl control = gridView.FindEditRowCellTemplateControl(gridView.Columns[0] as GridViewDataColumn, "upload_control_id") as ASPxUploadControl;

示例代码sn-p：

Protected Sub grid_RowInserting(ByVal sender As Object, ByVal e As DevExpress.Web.Data.ASPxDataInsertingEventArgs) Handles grdProyectos.RowInserting
        Dim grid As ASPxGridView = (TryCast(sender, ASPxGridView))
        Dim chk As CheckBox= grid.FindEditRowCellTemplateControl(grid.Columns("name_colum"), "nameCheckBox")
        Dim marcada as Boolean = chk.Checked
End Sub
