通过单击Gridview按钮显示gridview行的第一个列值 [英] To display 1st collumn value of a gridview row by clicking Gridview button

问题描述

大家好.

我有一个带有链接按钮的网格视图.

我只想要，

当我在网格视图中单击一个按钮时，该值应显示在Label中.

此图片将显示我的问题


背后的代码:

 受保护的 无效 GridView1_RowCommand(对象发​​件人，GridViewCommandEventArgs e)
    {

            开关(例如CommandName)
            {
                大小写 " :
                    {
                        字符串 FirstColumnFieldName = e.CommandArgument.ToString();

                        Label1.Text = FirstColumnFieldName;

                         break ;
                    }
                默认:
                     break ;
            }

            cmd = 新 SqlCommand(" ，同上)；
            cmd.ExecuteNonQuery();


    } 

并在Asp页面中:

  <asp:GridView ID="GridView1" runat="server" 
            onselectedindexchanged="GridView1_SelectedIndexChanged" OnRowCommand="GridView1_RowCommand" CellPadding="3" 
                                Width="609px" GridLines="None" BackColor="White" BorderColor="White" 
                                BorderStyle="Ridge" BorderWidth="2px" CellSpacing="1" HorizontalAlign="Center">
                                <RowStyle BackColor="#DEDFDE" ForeColor="Black" HorizontalAlign="Center" 
                                    VerticalAlign="Middle" />
            <Columns>
              <asp:TemplateField HeaderText="Payment" HeaderStyle-CssClass="title_bg" 
                    ItemStyle-HorizontalAlign="Center">
            <ItemTemplate> 
                <asp:LinkButton ID="lkDelte" runat="server" OnClientClick="return confirm(''Are you sure that Payment is Done ?'')"
                      CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
                      CommandName="y" ><img src="Images/A5.gif" alt="PayPal" border="0" /></asp:LinkButton>
            </ItemTemplate> 

<HeaderStyle CssClass="title_bg"></HeaderStyle>

<ItemStyle HorizontalAlign="Center"></ItemStyle>
        </asp:TemplateField>
</Columns>

                                <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
                                <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" 
                                    VerticalAlign="Middle" />
                                <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
                                <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" 
                                    HorizontalAlign="Center" VerticalAlign="Bottom" />

                                </asp:GridView>

谢谢......然后，您可以使用该值轻松填充标签.如果需要，还可以使用gridview的cellmouseclick事件.只需在Google上获取代码即可.

尝试:
随后将ItemName绑定到LinkButton的CommandArgument.

 <   asp:LinkBut​​ton     ID   ="     runat   =" 服务器" 文本  添加到购物车" 
        OnClick   ="   CommandArgument   <％#Eval(" ) ％> '   / >  

然后，您可以在后面的代码中像这样检索它:

 受保护的 无效 LinkBut​​ton1_Click(对象发​​件人，EventArgs e)
{
  LinkBut​​ton myButton =发件人 as  LinkBut​​ton;
  如果(myButton！= 空)
  {
     字符串 title = myButton.CommandArgument;
     // 现在使用此标题将其设置为标签的文本.
  }
} 

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

<asp:gridview id="GridView1" runat="server" onselectedindexchanged="GridView1_SelectedIndexChanged" onrowcommand="GridView1_RowCommand" xmlns:asp="#unknown">
 <columns>
              <asp:templatefield headertext="Payment" headerstyle-cssclass="title_bg">
                    ItemStyle-HorizontalAlign="Center">
            <itemtemplate> 
                <asp:linkbutton id="lkDelte" runat="server" onclientclick="return confirm(''Are you sure that Payment is Done ?'')">
                      CommandArgument=''<%# Eval("UserName") %>''
                      ><img src="Images/A5.gif" alt="PayPal" border="0" /></asp:linkbutton>
            </itemtemplate> 

<HeaderStyle CssClass="title_bg"></HeaderStyle>

<itemstyle horizontalalign="Center"></itemstyle>
        </asp:templatefield>
</columns> </asp:gridview>

 受保护的 无效 GridView1_RowCommand(对象发​​件人，GridViewCommandEventArgs e)
   {

          Label3.Text = GridView1.Rows [index] .Cells [ 1 ].Text;
   } 

Hello everyone.

I have a grid view with link button.

i just want,

This image will show my problem


Code Behind:

protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
    {

            switch (e.CommandName)
            {
                case "y":
                    {
                        string FirstColumnFieldName = e.CommandArgument.ToString();

                        Label1.Text=FirstColumnFieldName;

                        break;
                    }
                default:
                    break;
            }

            cmd = new SqlCommand("delete from Withdraw where UserName='FirstColumnFieldName'", con);
            cmd.ExecuteNonQuery();


    }

and in Asp Page :

  <asp:GridView ID="GridView1" runat="server" 
            onselectedindexchanged="GridView1_SelectedIndexChanged" OnRowCommand="GridView1_RowCommand" CellPadding="3" 
                                Width="609px" GridLines="None" BackColor="White" BorderColor="White" 
                                BorderStyle="Ridge" BorderWidth="2px" CellSpacing="1" HorizontalAlign="Center">
                                <RowStyle BackColor="#DEDFDE" ForeColor="Black" HorizontalAlign="Center" 
                                    VerticalAlign="Middle" />
            <Columns>
              <asp:TemplateField HeaderText="Payment" HeaderStyle-CssClass="title_bg" 
                    ItemStyle-HorizontalAlign="Center">
            <ItemTemplate> 
                <asp:LinkButton ID="lkDelte" runat="server" OnClientClick="return confirm(''Are you sure that Payment is Done ?'')"
                      CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
                      CommandName="y" ><img src="Images/A5.gif" alt="PayPal" border="0" /></asp:LinkButton>
            </ItemTemplate> 

<HeaderStyle CssClass="title_bg"></HeaderStyle>

<ItemStyle HorizontalAlign="Center"></ItemStyle>
        </asp:TemplateField>
</Columns>

                                <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
                                <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" 
                                    VerticalAlign="Middle" />
                                <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
                                <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" 
                                    HorizontalAlign="Center" VerticalAlign="Bottom" />

                                </asp:GridView>

Thanks....

解决方案

When you use the gridview''s rowheader clicked event then you can access the clicked row and all its cells. Then you can use that value to populate a label easily. If you need then you can use gridview''s cellmouseclick event also. Just google it for code.

Try:
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") %>' />

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.
  }
}

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

<asp:gridview id="GridView1" runat="server" onselectedindexchanged="GridView1_SelectedIndexChanged" onrowcommand="GridView1_RowCommand" xmlns:asp="#unknown">
 <columns>
              <asp:templatefield headertext="Payment" headerstyle-cssclass="title_bg">
                    ItemStyle-HorizontalAlign="Center">
            <itemtemplate> 
                <asp:linkbutton id="lkDelte" runat="server" onclientclick="return confirm(''Are you sure that Payment is Done ?'')">
                      CommandArgument=''<%# Eval("UserName") %>''
                      ><img src="Images/A5.gif" alt="PayPal" border="0" /></asp:linkbutton>
            </itemtemplate> 

<HeaderStyle CssClass="title_bg"></HeaderStyle>

<itemstyle horizontalalign="Center"></itemstyle>
        </asp:templatefield>
</columns> </asp:gridview>

protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
   {

          Label3.Text = GridView1.Rows[index].Cells[1].Text;
   }
