GridView TemplateField中的禁用按钮

Question

我有下面的gridview控件

<asp:Panel runat="server" ID="pnlBeforeSave" Visible="true">
<asp:GridView ID="gvP" runat="server" AutoGenerateColumns="false" AllowPaging="false"
  AllowSorting="false" CssClass="list-table" HeaderStyle-CssClass="header">
  <Columns>

  <asp:TemplateField HeaderText="Action" ItemStyle-Width="20%" HeaderStyle-HorizontalAlign="Center"
  ItemStyle-CssClass="unsortable">
  <ItemTemplate>
  <input id="btnPay" type="button" onclick="javascript:OpenEditPaymentItemDialogPage('<%# Eval("PmtId") %>');"
   value="Edit" class="button save" style="width: 80px" />
   </ItemTemplate>
   </asp:TemplateField>
   </Columns>
   </asp:GridView>
</asp:Panel>

在我将griview数据集保存到数据库后，我必须禁用griview。但btnPay仍处于启用状态。我需要从任何想法背后的代码来做吗？

Answer 1

我已经做完了。

C#

ScriptManager.RegisterStartupScript(this, this.GetType(), "HidePaymentItemButtons", "javascript:disableAllButtons_PT;", true);

JS

        function disableAllButtons_PT() {
        var gridViewID = "<%=gvPamentItemsList.ClientID %>";
        var gridView = document.getElementById(gridViewID);
        var gridViewControls = gridView.getElementsByTagName("input");

        for (i = 0; i < gridViewControls.length; i++) {
            // if this input type is button, disable
            if (gridViewControls[i].type == "submit") {
                gridViewControls[i].disabled = true;
            }
        }

您需要通过添加使用RunAt=“type=”元素来使输入“按钮”在代码后台可访问

因此，您的代码将如下所示

<ItemTemplate>   
<input ruat="server" id="btnPay" type="button" onclick="javascript:OpenEditPaymentItemDialogPage('<%# Eval("PmtId") %>');"    value="Edit" class="button save" style="width: 80px" />  
  </ItemTemplate> 

或者使用Asp:Button

<ItemTemplate>   
<asp:button ruat="server" id="btnPay" type="button" onClientclick="javascript:OpenEditPaymentItemDialogPage('<%# Eval("PmtId") %>');"    value="Edit" class="button save" style="width: 80px" >   </asp:button>
  </ItemTemplate> 

然后利用datagridview的RowDataBound事件和disable按钮..

保存数据后，放入以下代码。我测试过了。onlcick已禁用。

for (int i = 0; i < gvP.Rows.Count; i++)
{
   HtmlInputButton btn = (HtmlInputButton)gvP.Rows[i].FindControl("btnPay");
   if (btn != null) btn.Disabled = true;
}
