如何在后面的代码中获取gridview中当前行的DataKeyNames [英] how get DataKeyNames of current rows in gridview in code behind

问题描述

嗨 我想在后面的代码中编辑gridview
我如何获得fied ID

我只想找到用户要编辑的DataKeyNames
tnx

解决方案

将GridView中的DataKeyField设置为

< asp:gridview id = "  runat = "  datakeynames = "  ID" xmlns:asp =  #unknown" > 
......
</  asp:gridview  >  

然后，您可以按以下方式获取每一列的键值:

  for ( int  i =  0 ；我<  gvList.Rows.Count; i ++)
    {
         Int32 键= Convert.ToInt32(gvList.DataKeys [i] .Value.ToString());
    } 

或者，如果您在任何单元事件之间进行操作，则可以将DataGridViewCellEventArgs的对象用作

  Int32 键= Convert.ToInt32(gvList.DataKeys [e.RowIndex] .Value); 

  int 键= Convert.ToInt32(GridView1.DataKeys [e.RowIndex] .Value);

您可以通过，分隔来设置多个数据键名.
您可以通过GridView1.DataKeys [e.RowIndex] .Values ["ID"];

hi i want edit gridview in code behind
how can i get fied ID

i just want to find DataKeyNames that user want to editing
tnx

解决方案

Set the DataKeyField in GridView as

<asp:gridview id="gvList" runat="server" datakeynames="Id" xmlns:asp="#unknown">
...........
</asp:gridview>

Then you can get the key value for each column as:

for (int i = 0; i < gvList.Rows.Count; i++)
    {
        Int32 key = Convert.ToInt32(gvList.DataKeys[i].Value.ToString());
    }

Or, if you are working between any cell-event you can use the object of DataGridViewCellEventArgs as

Int32 key = Convert.ToInt32(gvList.DataKeys[e.RowIndex].Value);

int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);

you can set multiple datakeynames by , separation.
and you can access this by GridView1.DataKeys[e.RowIndex].Values["ID"];
