绑定在GridView的编辑项模板下拉列表 [英] Binding dropdown list in a gridview edit item template

问题描述

我可以绑定在编辑项模板DropDownList中。下拉列表null值。

i can bind the dropdownlist in the edit item template. The drop down list is having null values.

protected void grdDevelopment_RowDataBound(object sender, GridViewRowEventArgs e) 
{   
  DropDownList drpBuildServers = new DropDownList();

  if (grdDevelopment.EditIndex == e.Row.RowIndex)    
  {        
      drpBuildServers = (DropDownList)e.Row.Cells[0].FindControl("ddlBuildServers");    
  }
}

也得到一个错误

无法加载视图状态。到被加载视图状态的控件树必须在使用了previous请求期间保存视图状态控件树相匹配。例如，动态添加控制时，一个后回过程中添加的控制必须初始请求过程中添加的控制的类型和位置相匹配。

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
