我在网格视图中面临一个问题，基本上我想要实现的是以下内容:我有一个网格视图，其中我的第一列是链接按钮，我必须设置一个条件，使第二列的值是并被输入到ac#方法中，用于填充我需要在第一列中分配的值.

我正在尝试下面的代码，但是当我查看网格时，其显示的第一列值为空白.
Aspx页面:

<asp:TemplateField HeaderText="FileName" ItemStyle-HorizontalAlign="Center">  <itemtemplate> <asp:LinkButton ID="btn"  runat="server" CommandName="Click"/> </itemtemplate>

aspx.cs-我在rowdatabound上编写的以下代码

aspx.cs - below code i have written on rowdatabound

if (e.Row.RowType == DataControlRowType.DataRow) 
{
 int EmpiD = Int32.Parse(e.Row.Cells[2].Text);
 DataSet EmpIDDs = GetEMP.getValue(EmpiD);
 DataRow EmpRow = EmpIDDs.Tables[0].Rows[0];
 e.Row.Cells[0].Text = EmpRow[3].ToString(); }

推荐答案

在行数据绑定内，通过以下代码获取列对象

Inside row databound, get the column object by the following code

Label TestLabel = (Label)e.Row.FindControl("MyLabel");
   TestLabel.Text= "Hello";

然后为其分配任何属性值.

Then assign any property value to it.

写入gridview行命令事件args

此处的命令名称为

声明字符串value = string.empty;

if(e.commnadName =="click")
{

//如果您放置文本框，请找到文本框
Gridviewrow row = gridview1.rows [2] as gridviewrow

文本框txtid = row.fincontrol(项目模板中的txtid")；

值= txtid.Text; //在这里您可以在文本框中读取值；

}


告诉我，不管您是否了解

Write in gridview row command event args

here the command name is click

declare string value=string.empty;

if(e.commnadName=="click")
{

//if you put the text box find the text box
Gridviewrow row= gridview1.rows[2] as gridviewrow

textbox txtid=row.fincontrol("txtid in item template");

value=txtid.Text; // Here you can read the value in the textbox ;

}


inform me, you get it or not

为此，您需要找到列单元格的控件，然后需要更改值.

希望对您有帮助.
