问题描述

大家好
我有一个gridview，因为我有两个coloums，一个有界字段，另一个是链接按钮..如果单击链接按钮，则相关的有界字段文本应复制到另一页

hi all
i have one gridview in that i have two coloums one bounded field another one is link button.. if i click link button the related bounded field text should be copied to another page

<asp:GridView ID="GridView1" runat="server" ShowHeader="False"

                   AutoGenerateColumns="false" onrowcommand="GridView1_RowCommand">
               <Columns>
               <asp:BoundField DataField="Address" />
                <asp:TemplateField HeaderText="Jobs">
               <ItemTemplate>
               <asp:LinkButton ID="Update" runat="server" CommandName="cmdid" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>">Update</asp:LinkButton>
               </ItemTemplate>
           </asp:TemplateField>
               </Columns>
               </asp:GridView>

public void Gridbind()
{
dt = new DataTable();

            dt.Columns.Add(new DataColumn("Address", typeof(string)));
            DataSet dl = Deliverydetails();
            int count = dl.Tables[0].Rows.Count;
            for(int i=0;i<count;i++)

            {

                DataRow dr = null;

                dr = dt.NewRow();

           string data = dl.Tables[0].Rows[i]["clad_name"].ToString() + ',' +.......;

                dr["Address"]=data;

                  dt.Rows.Add(dr);



            }

           GridView1.DataSource=dt.DefaultView;

            GridView1.DataBind();

}

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
      {
          if (e.CommandName == "cmdid")
          {
              int index = Convert.ToInt32(e.CommandArgument);

              GridViewRow selectrow = GridView1.Rows[index];

// here how to get value of selected rows Text
       
          }

推荐答案

通过这种方式:
以下将ItemName绑定到LinkButton的CommandArgument.

Ty this way:
Following binds the ItemName to the CommandArgument of the LinkButton.

<asp:LinkButton ID="LinkButton1" runat="server" Text="Add to cart"

   OnClick="LinkButton1_Click" CommandArgument='<%# Eval("ItemName") %>' />

然后，您可以在后面的代码中像这样检索它:

You can then retrieve it like this in the code behind:

protected void LinkButton1_Click(object sender, EventArgs e)
{
  LinkButton myButton = sender as LinkButton;
  if (myButton != null)
  {
     string title = myButton.CommandArgument;
     // use this title now to set as a text for your label.
     // store it and access in another page.
  }
}

发送方持有对触发事件处理程序的LinkButton的引用.
您可以将对象转换为LinkButton，然后检索其CommandArgument并将其转换为字符串.

The sender holds a reference to the LinkButton that triggered the event handler.
You can cast the object into a LinkButton and then retrieve its CommandArgument and cast that into string.

 if (e.CommandName == "cmdid")
          {
              int index = Convert.ToInt32(e.CommandArgument);
 
              GridViewRow selectrow = GridView1.Rows[index];
               string value=selectrow .Cells[0].Text;
                Response.Redirect("address.aspx?id="+value);
}

您现在可以获取querystring值并在下一页访问它.

希望对您有帮助

you can now get the querystring value and access it in the next page.

Hope this helps you

刚刚更改
受保护的void GridView1_RowCommand(对象发送者，GridViewCommandEventArgs e)
{
如果(e.CommandName =="cmdid")
{
int索引= Convert.ToInt32(e.CommandArgument);
字符串值= GridView1.Rows [index] .Cells [1] .Text.ToString();


Response.Redirect("address.aspx?id =" + value);

}
}

just Changed
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "cmdid")
{
int index = Convert.ToInt32(e.CommandArgument);
string value = GridView1.Rows[index].Cells[1].Text.ToString();


Response.Redirect("address.aspx?id=" + value);

}
}
