推荐答案

请参考以下代码

refer the following code

<asp:GridView ID="grvTest" runat="server" AutoGenerateColumns="false"

    onrowcommand="grvTest_RowCommand">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:LinkButton ID="lnkTest" runat="server" Text="Move"       CommandName="Move"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

protected void grvTest_RowCommand(object sender, GridViewCommandEventArgs e)
        {
          if (e.CommandName == "Move")
          {
           GridViewRow row=(GridViewRow)((LinkButton)e.CommandSource).NamingContainer;
           string name = row.Cells[0].Text;
           Response.Redirect("Page2.aspx?name=" + name);
          }
        }

收集所有网格单元格值并按上面给出的形式形成url

collect all grid cell values and form the url as given above

这里是一个示例，您可以通过查询字符串将值传递给其他Webform

Here''s an example for you to pass the value to other webform through query string

<asp:TemplateField HeaderText="Document ID" HeaderStyle-CssClass="gridheaderleft"

                                        ItemStyle-CssClass="boundfield" HeaderStyle-Width="100px">
                                        <ItemTemplate>
                                            <asp:HyperLink ID="hyperDocketDetails" Text='<%# bind("ClientDocumentIdentifier") %>'

                                                runat="server" NavigateUrl='<%# "DocumentDetails.aspx?id="+ DataBinder.Eval(Container.DataItem,"ID") +"&moduleid="+ Request["moduleid"] + "&retURL=" + HttpUtility.UrlEncode(Request.Path + "?" + Request.QueryString) %>' />
                                            <asp:Label ID="lblDocket" Text='<%# bind("ClientDocumentIdentifier") %>' runat="server" />
                                        </ItemTemplate>
                                    </asp:TemplateField>

您好，

首先尝试找到GridViewRow(使用LinkBut​​ton跟踪单击的行).

然后使用GridView.Rows [index] .FindControl("ControlID")找到所有所需的控件.

将控件投放到适当的样式中，例如"DropDown"，"Label"等...

然后使用Response.Redirect(url)，您可以根据需要进行重定向.

问候，
达摩什

Hi,

First of all try to locate GridViewRow(Track which row is clicked using LinkButton).

Then find all the desired control using GridView.Rows[index].FindControl("ControlID").

Cast control into appropriate tyle like "DropDown","Label" etc...

then using Response.Redirect(url), you can redirect as per your requirement.

Dharmesh
