带有datagridview的按钮 [英] button with datagridview

问题描述

我在datagridview的第一栏中有一个按钮.每当我单击datagridview中的按钮时，我想删除该行plz给出一个想法

I have a button in the first column of the datagridview. Whenever I click on the button in the datagridview, i want to delete that row plz give an idea

推荐答案

将该按钮的命令名称设置为"Delete"，然后检查datagrid的rowcommand属性中的命令名称，并在那里执行delete操作和bindgrid操作，以便删除该记录后的网格将被更新...

也不要忘记将id属性设置为数据键，这样就可以在命令参数中传递它并删除想要的行.


例如..

set the command name of that button to "Delete" and then check the command name in the datagrid''s rowcommand property and perform delete operation and bindgrid operation there so the grid after deleting that record will be updated...

also dont forget to make the id property as a datakey so you can pass it in command argument and delete the row you wish to.


for eg..

protected void datagrid_RowCommand(object sender, GridViewCommandEventArgs e)
       {
           try
           {
               if (e.CommandName == "Delete")
               {
                   int Args = Convert.ToInt32(e.CommandArgument);
                   string _id = grddisplayrequest.DataKeys[Args]["ID"].ToString();

/* Perform Delete operation here */
/* bind grid operation here */
               }
           }
           catch (Exception ex)
           {
               Response.Write(ex.Message);
           }
       }
   }
