i want to display the records showing in the gridview webform. but when ever i click over the edit button its always load first record. e.g i click over the edit button in print of 2nd record it will load the first record into the webform.

推荐答案

你做错了。



参考 - GridView.RowEditing事件 [ ^ ]。

You are doing wrong.

Refer - GridView.RowEditing Event[^].

protected void TaskGridView_RowEditing(object sender, GridViewEditEventArgs e)
{
    //Set the edit index.
    TaskGridView.EditIndex = e.NewEditIndex;
    //Bind data to the GridView control.
    BindData();
}

按照以下简单步骤：

Follow below simple steps:

• 从要显示gridview数据的网页上的工具箱中拖放GridView

• Drag and drop a GridView from toolbox on Webpage where you wants to show the gridview data

添加按钮GridView显示数据的单击事件

Add a Button On which click event the GridView displays data

创建类似

SqLConnection con=new SqlConnection(ConfigurationManager.ConnectedStrings["NameOfYourConnectionString"].ToString());//for connection

• 现在转到按钮和代码的点击事件，如下所示：

con.open();
SqlCommand cmd=new SqlCommand("select * from YourTableName",con);
SqlDataReader dr=cmd.ExecuteReader();
if(dr.Read())
{
   SqlDataAdapter da=new SqlDataAdapter(cmd);
   DataSet ds=new DataSet();
   da.Fill(ds);
   GridView.DataSource=ds;
   GridView.DataBind();
   con.close();
}
else
{
 //code for error
}
