在网格视图的标题模板中查找控件 [英] Finding control inside the header template of a grid view

问题描述

我有这样的网格...

 <   asp：GridView     ID   =  gdv    runat   =  server >  
 <  列 >  
 <   asp：TemplateField  >  
 <   HeaderTemplate  >  
 <   asp：TextBox     ID   =  txt    runat   =  server < span class =code-keyword>>  <   / asp：TextBox  < span class =code-keyword>>  
 <   / HeaderTemplate  >  
 <   ItemTemplate  >  
 <   asp：标签    ID   =  lbl    runat   =  server   文本  ='  <％＃DataBinder.Eval（Container.DataItem，  col1）％> ' >  <   / asp：标签 >  
 <   / ItemTemplate  < span class =code-keyword>>  
 <   / asp：TemplateField  >  
  <   asp：TemplateField  >  
 <   ItemTemplate  >  
 <   asp：DropDownList     ID   =  ddl    runat   =  server < span class =code-attribute>   DataTextField   = 项 <温泉n class =code-attribute>   DataValueField   =  value >  <   / asp：DropDownList  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   /列 >  
 <   / asp：GridView  >  

怎么样找到后面代码中的一个头模板中的TextBox控件（C＃代码）？

解决方案

通过处理gridview的RowDataBound（）事件，你可以找到标题模板内的文本框控件。

 受保护  void  gdv_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
  if  （gdv.HeaderRow！=  null ）
 {
 TextBox txt =（TextBox）gdv.HeaderRow.FindControl（  txt）; 
} 
}

  protected   void  chkSelectAll_CheckedChanged（ object  sender，EventArgs e）

 chk.Checked =（（CheckBox）sender）.Checked;

}  

I have a grid like this...

<asp:GridView ID="gdv" runat="server">
            <Columns>
                <asp:TemplateField>
                    <HeaderTemplate>
                        <asp:TextBox ID="txt" runat="server"></asp:TextBox>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:Label ID="lbl" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "col1") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:DropDownList ID="ddl" runat="server" DataTextField="item" DataValueField="value"></asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

How can find the TextBox control which is there inside one of the header template in code behind(C# code) ?

解决方案

By handling RowDataBound() event of the gridview you can find Textbox control inside header template.

protected void gdv_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (gdv.HeaderRow != null)
        {
            TextBox txt = (TextBox)gdv.HeaderRow.FindControl("txt");
        }
    }
