推荐答案

您必须在gridview的 RowDataBound 事件处理程序中编写代码以检查记录的状态，并相应地使打印图标启用或禁用特定行。请在下面查看类似示例。

You have to write code in RowDataBound event handler of gridview to check the status of record and accordingly make print icon enable or disable of particular row. Please check below the similar example.

// The event handler of RowDataBound event of gridview. Please make sure that this event should be called in defination of gridview in source. 
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
// Here we check that row should be a datarow not a header or footer
  if (e.Row.RowType == DataControlRowType.DataRow) 
  { 
// Here we find the imagecontrol (print icon) and hiddenfield (status). Make sure that you added these controls in ItemTemplate or AlternateItemTemplate of gridview and assign the status of record in hiddenfield..
    ImageButton imgPrint = (ImageButton )e.Row.FindControl("PrintImageButtonName"); 
    HiddenField hdnStatus = ((HiddenField)e.Row.FindControl("StatusHiddenFieldName")); 

// Here we check for the status of record and enable/disable imagebutton accordingly.
    if(hdnStatus.Value.ToLower()=="signed")
    {
      imgPrint.Enabled=true;
    }
    else
    {
      imgPrint.Enabled=false;
    }
  } 
} 

我建​​议你在 RowDataBound 中写下你的逻辑GridView控件的事件如下：

I would suggest you to write your logic in RowDataBound event of the GridView control as follows:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                ImageButton btnPrint = (ImageButton)e.Row.FindControl("btnPrint");
                string status = e.Row.Cells[3].Text;
                if (status == "signed")
                {
                    btnPrint.Visible = true;
                }
                else
                {
                    btnPrint.Visible = false;
                }
            }
        }

这里我假设数据源的第三列具有状态值（即签名/待定）。



如果您需要完整的代码，请告诉我。

Here I'm assuming that third column of the data source having the status value (i.e. signed / pending).

Please let me know in case you need the complete code.
