这是我第一次使用RadGrid

主要问题是如何从代码背后访问这个网格中的控件，以及如何绑定其中的一些控件或处理其中的事件？？
例如，如何从代码背后访问txt_lect_in？
请尝试使用以下代码片段。
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
}
}
