1. I put a checkbox all-selected column in gridview, but after running, the column is not displayed
code show as below
<asp: GridView ID = "gvComUnion" runat = "server" AllowPaging = "True" AutoGenerateColumns = "False"
       BackColor = "White" BorderColor = "# 3366CC" BorderStyle = "Solid" BorderWidth = "1px"
       CellPadding = "4" Font-Size = "12px" HorizontalAlign = "Left" OnPageIndexChanging = "gvParty_PageIndexChanging"
       OnRowEditing = "gvParty_RowEditing" PageSize = "15" Width = "556px" OnRowDataBound = "gvParty_RowDataBound" OnLoad = "gvParty_Load" OnRowCreated = "gvParty_RowCreated" Font-Names = "宋体" OnSelectedIndexChanged = "gvComUnion_SelectedIndexd
       <PagerSettings FirstPageText = "FirstPage" LastPageText = "Last Page" Mode = "NextPreviousFirstLast"
         NextPageText = "Next Page" PreviousPageText = "Previous Page" />
       <FooterStyle BackColor = "#EFEFEF" ForeColor = "# 000D47" />
        <Columns>
        
            <asp: TemplateField>
                <HeaderTemplate>
                  <asp: CheckBox ID = "CheckBox1" runat = "server" Text = "Select All" AutoPostBack = "true" OnCheckedChanged = "CheckAll" />
                </ HeaderTemplate>
                <ItemTemplate>
                  <asp: CheckBox ID = "ItemCheckBox" runat = "server" />
                </ ItemTemplate>
              </ asp: TemplateField>



            <asp: BoundField DataField = "COMID" HeaderText = "Member ID" />
            <asp: BoundField DataField = "COMNAME" HeaderText = "unit name" />
            <asp: BoundField DataField = "COMINLOW" HeaderText = "ownership" />
            <asp: BoundField DataField = "BUSINESS" HeaderText = "Industry" />
            <asp: BoundField DataField = "DISTRICT" HeaderText = "located area" />
            <asp: BoundField DataField = "STATUS" HeaderText = "Status" />
            <asp: CommandField EditText = "Details" HeaderText = "Details" ShowEditButton = "True" />

        </ Columns>

        <RowStyle ForeColor = "# 003399" HorizontalAlign = "Center" />
        <SelectedRowStyle BackColor = "# 003399" Font-Bold = "True" ForeColor = "# CCFF99" />
        <PagerStyle BackColor = "# EFEFEF" ForeColor = "# 003399" HorizontalAlign = "Right" />
        <HeaderStyle BackColor = "# 003399" BorderStyle = "None" Font-Bold = "True" ForeColor = "White" />
        <AlternatingRowStyle BackColor = "# EFEFEF" />
        
    </ asp: GridView>


Question 2;
The reference code is as follows
<input id = "Text1" type = "text" onclick = "return showCalendar ('Text1', 'y-mm-dd');" onfocus = "return showCalendar ('Text1', 'y-mm-dd') ; "/> No line breaks here <img src =" ../ images / 1.gif "alt =" select date "width =" 25px "height =" 21px "style =" CURSOR: hand "onclick =" return showCalendar ('Text1', 'y-mm-dd'); "/>
Which cannot be newline, otherwise the operation is invalid, I do not know why

Give you a good one:

<asp: TemplateField>
                                <EditItemTemplate>
                                    <asp: CheckBox ID = "CheckBox1" runat = "server" />
                                </ EditItemTemplate>
                                <ItemTemplate>
                                    <asp: CheckBox ID = "chbitem" runat = "server" />
                                </ ItemTemplate>
                                <HeaderTemplate>
                                   <input id = "chkAll" onclick = "javascript: SelectAllCheckboxes (this);"
              runat = "server" type = "checkbox" />
                                </ HeaderTemplate>
                            </ asp: TemplateField>


function SelectAllCheckboxes (spanChk) {

   // Added as ASPX uses SPAN for checkbox
   var oItem = spanChk.children;
   var theBox = (spanChk.type == "checkbox")?
        spanChk: spanChk.children.item [0];
   xState = theBox.checked;
   elm = theBox.form.elements;

   for (i = 0; i <elm.length; i ++)
     if (elm [i] .type == "checkbox"&&
              elm [i] .id! = theBox.id)
     {
       // elm [i] .click ();
       if (elm [i] .checked! = xState)
         elm [i] .click ();
       //elm[i].checked=xState;
     }
 }

Just call it

Find the reason

Still can't show the select all column, isn't the property needed to be set

It seems that the first column of gridview is not displayed.
