具有多个绑定方法的gridview [英] gridview having more than one bind method

问题描述

我正在做location-city-state-country页面.在location页面中，我有3个下拉列表，并且基于在下拉列表中选择的值将数据绑定到gridview.为此，我使用了以下方法

i am doing location-city-state-country page.in location page i have 3 dropdowns and based on the values selected in dropdown list data to the gridview is binded.for that i use follwing method

public void fillgrid()
       {
           Int32 country_id = Convert.ToInt32(ddcountry.SelectedValue == "" ? "0" : ddcountry.SelectedValue);
           Int32 state_id = Convert.ToInt32(ddstate.SelectedValue == "" ? "0" : ddstate.SelectedValue);
           Int32 city_id = Convert.ToInt32(ddcity.SelectedValue == "" ? "0" : ddcity.SelectedValue);
           Common obj = new Common();
           DataSet ds = obj.BindingGridview(country_id, state_id, city_id);
           gvlocation.DataSource = ds;
           gvlocation.DataBind();
       }

我也有一个搜索按钮，并根据搜索文本框中的值绑定了gridview.为此，我使用了以下代码

i have also a search button and i bind the gridview based on value in search textbox.for that i use follwing code

public void BindGV(string locationname)
     {

         Common obj = new Common();
         locationname = "%" + locationname + "%";
         DataSet ds = obj.GetAllLocation(locationname);
         gvlocation.DataSource = ds.Tables[0];
         gvlocation.DataBind();

     }

问题是在编辑/更新/删除期间我只能将一种方法绑定到gridview.通常我选择第一种方法.但是当我按显示搜索结果的gridview的编辑按钮时，这会导致问题.
受保护的void gvlocation_RowEditing(对象发送者，GridViewEditEventArgs e)
{
gvlocation.EditIndex = e.NewEditIndex;
fillgrid();
}

The problem is that i can bind only one method to gridview during edit/update/delete.normally i select first method.but when i press edit button of gridview which shows search Result, it causes problem .
protected void gvlocation_RowEditing(object sender, GridViewEditEventArgs e)
{
gvlocation.EditIndex = e.NewEditIndex;
fillgrid();
}

推荐答案

更正此行:

Correct this line:

gvlocation.DataSource = ds;

到

to

gvlocation.DataSource = ds.Tables[0];

您取一个静态标志并设置为搜​​索，然后在u处于编辑模式下时根据标志填充，请记住在下拉列表选择后取消设置

you sd take a static flag and set on search then when u are in edit mode fill according to flag remember to unset after dropdown select
