C＃中的GridView HyperLink字段 [英] GridView HyperLink field in C#

问题描述

看看下面的代码：

 < asp：HyperLinkField 
 DataNavigateUrlFields =NameID
 DataNavigateUrlFormatString =names.aspx？nameid = {0}
 DataTextField =name
 HeaderText =名称
 ItemStyle-Width =100px
 ItemStyle -Wrap =true/> 
  

只需要名称id即可导航到下一页。我将如何包含
两个不在gridview中的其他参数。我使用的导航url必须使用已经存在于gridview中的关键字和数据库表中的其他两个参数。我尝试使用所有这些代码。没有什么对我有用。

 < asp：HyperLinkField DataTextField =KeywordDataNavigateUrlFields =Keyword
 DataNavigateUrlFormatString =KeywordSrchSumDtl.aspx？关键字= {0}&状态= {1}和城市= {2}
 HeaderStyle-VerticalAlign =BottomItemStyle-Horizo​​ntalAlign =center/> 
  

我无法使用上面的代码，因为状态和城市不在gridview中，而是在我的数据表。

我也尝试使用下面的代码，但它不起作用

 < asp：TemplateField HeaderText =KeywordItemStyle-Horizo​​ntalAlign =CenterFooterStyle-Horizo​​ntalAlign =Center> 
< ItemTemplate> 
< asp：HyperLink ID =linkrunat =serverNavigateUrl ='<％＃KeywordSrchSumDtl.aspx？Keyword =Eval（Keyword）+& State =+ Request。 QueryString [State]％>'Text ='<％＃Eval（Keyword）％>'>< / asp：HyperLink> 
< / ItemTemplate>< / asp：TemplateField> 
  

我也试过这个，

<$ p （）（）（）（）{$ p> < asp：HyperLink ID =Link1runat =ServerNavigateUrl ='<％＃redirectURL（）+ Server.UrlEncode ）％>'Text ='<％＃DataBinder.Eval（Container.DataItem，Keyword）％>'>< / asp：HyperLink>< / ItemTemplate>< / asp：TemplateField>

.aspx.cs
returnKeywordSrchSumDtl.aspx？Keyword =+ // DONNO如何在这里调用关键字//
+& State =+ System.Web.HttpContext.Current.Request.QueryString [State]
+& City =+ System.Web.HttpContext.Current.Request.QueryString [City];


我不知道如何解决这个问题..请帮我解决这个问题。
Thanks。

解决方案使用 DataNavigateUrlFields 属性，逗号KeywordSrchSumDtl.aspx？Keyword = {0}& State = {1}&City = {2}

 < asp：HyperLinkField DataNavigateUrlFields =关键字，状态，城市
 DataNavigateUrlFormatString =KeywordSrchSumDtl.aspx？Keyword = {0 }& State = {1}&City = {2}
 Text =查看详情/> 
  

几个例子：

在 RowDataBound NavigateUrl GridView

 < asp：GridView ID =GridView1runat =server
 AutoGenerateColumns =False
 DataKeyNames =关键字
 DataSourceID =SqlDataSource1
 onrowdatabound =GridView1_RowDataBound> 
< asp：TemplateField HeaderText =KeywordItemStyle-Horizo​​ntalAlign =CenterFooterStyle-Horizo​​ntalAlign =Center> 
< ItemTemplate> 
< asp：HyperLink ID =linkrunat =serverText ='<％＃Eval（Keyword）％>'/> 
< / ItemTemplate> 
< / asp：TemplateField> 
 ....... 
< / asp：GridView> 
  

后面的代码：

  protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e）
 {
 if（e.RowType == DataControlRowType.DataRow）
 {
 HyperLink hl = （超链接）e.Row.FindControl（ 链接）; 
 if（hl！= null）
 {
 DataRowView drv =（DataRowView）e.Row.DataItem; 
 string keyword = drv [Keyword]。ToString（）; 
 string state = Request.QueryString [State]; 
 string city = Request.QueryString [City]; 
 hl.NavigateUrl =〜/ KeywordSrchSumDtl.aspx？Keyword =+ keyword +& State =+ Server.UrlEncode（state）+& City =+ Server.UrlEncode（city）; 
} 
} 
} 
  

Take a Look at the following code:

        <asp:HyperLinkField 
        DataNavigateUrlFields="NameID" 
        DataNavigateUrlFormatString="names.aspx?nameid={0}"
        DataTextField="name" 
        HeaderText="Name" 
        ItemStyle-Width="100px"
        ItemStyle-Wrap="true" />

It takes only the name id to navigate to the next page. How will i include the two other parameters which are not in the gridview. The navigate url im using has to take the keyword which is already present in the gridview and the other two parameters from the database table. I tried using all these codes. Nothing did work for me.

    <asp:HyperLinkField DataTextField="Keyword" DataNavigateUrlFields="Keyword"
     DataNavigateUrlFormatString="KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"
     HeaderStyle-VerticalAlign="Bottom" ItemStyle-HorizontalAlign="center" />

i cant use the above the code because the state and city are not in the gridview but available in my data table.

I tried using the following code too, but it doesnt work

     <asp:TemplateField HeaderText="Keyword"  ItemStyle-HorizontalAlign="Center"          FooterStyle-HorizontalAlign="Center">
    <ItemTemplate>
    <asp:HyperLink ID="link" runat="server" NavigateUrl='<% # "KeywordSrchSumDtl.aspx?Keyword="Eval("Keyword")+"&State="+Request.QueryString["State"]%>' Text='<%# Eval("Keyword") %>'></asp:HyperLink>
    </ItemTemplate></asp:TemplateField>

and i also tried this,

    <asp:HyperLink ID="Link1" runat="Server" NavigateUrl='<%#redirectURL()+Server.UrlEncode((Eval("Keyword")).ToString())%>' Text='<%# DataBinder.Eval(Container.DataItem,"Keyword") %>'></asp:HyperLink></ItemTemplate></asp:TemplateField>

    .aspx.cs
    return "KeywordSrchSumDtl.aspx?Keyword=" + //I DONNO HOW TO CALL THE KEYWORD HERE//
     + "&State=" + System.Web.HttpContext.Current.Request.QueryString["State"]
     + "&City=" + System.Web.HttpContext.Current.Request.QueryString["City"];

I Donno How to solve this.. Please Help me solve this problem. Thanks.

解决方案

Use the DataNavigateUrlFields property, comma-delimited value with the fields for parameters in "KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"

<asp:HyperLinkField DataNavigateUrlFields="Keyword,State,City"
                    DataNavigateUrlFormatString="KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}" 
                    Text="View Details" />

A couple of examples:

EDIT:

Set NavigateUrl of HyperLink in RowDataBound event of GridView

<asp:GridView ID="GridView1" runat="server" 
              AutoGenerateColumns="False" 
              DataKeyNames="Keyword"
              DataSourceID="SqlDataSource1" 
              onrowdatabound="GridView1_RowDataBound">
   <asp:TemplateField HeaderText="Keyword"  ItemStyle-HorizontalAlign="Center"          FooterStyle-HorizontalAlign="Center">
      <ItemTemplate>
          <asp:HyperLink ID="link" runat="server" Text='<%# Eval("Keyword") %>' />
      </ItemTemplate>
    </asp:TemplateField>
    .......
</asp:GridView>

Code behind:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
 if (e.Row.RowType == DataControlRowType.DataRow) 
 { 
    HyperLink hl = (HyperLink)e.Row.FindControl("link"); 
    if (hl != null) 
    { 
        DataRowView drv = (DataRowView)e.Row.DataItem; 
        string keyword = drv["Keyword"].ToString(); 
        string state = Request.QueryString["State"]; 
        string city = Request.QueryString["City"]; 
        hl.NavigateUrl = "~/KeywordSrchSumDtl.aspx?Keyword=" + keyword + "&State=" + Server.UrlEncode(state) + "&City=" + Server.UrlEncode(city); 
    } 
 } 
}
