的主要问题是如何从代码中访问这个网格控件后面如何绑定他们中的一些或处理的事件他们？

例如如何从后面的代码访问txt_lect_in？

Answer 1

请试试下面的代码片段。

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
{ 
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode) 
    { 
     GridEditFormItem item = e.Item as GridEditFormItem; 
     TextBox txt_lect_in = item.FindControl("txt_lect_in") as TextBox; 
     //Access your textbox heer 
    } 
} 
//OR 
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) 
{ 
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode) 
    { 
     GridEditFormItem item = e.Item as GridEditFormItem; 
     TextBox txt_lect_in = item.FindControl("txt_lect_in") as TextBox; 
     //Access your textbox heer 
    } 
}
