我在asp.net c#中开发应用程序,因为我有问题.
问题是
我在asp.net页面上有三个字段,其中有银行名称,分行和IFSC代码,当我单击保存按钮时,这三个字段是必填字段,

但是当我点击搜索&清除按钮,它也应该要求填写这些字段.
单击其他按钮时如何限制此

“请填写此字段”.

假设我仅搜索sbi bank,它要求输入每个字段.

我的密码
    
        
           
              
                    输入银行
                   

          </div>
          <div class="form-group col-md-3">
            <label for="exampleInputEmail1">
               Enter Branch</label>
           <asp:TextBox ID="txtBranchName" runat="server" type="text" CssClass="form-control" PlaceHolder="Enter Branch" required />

          </div>
         <div class="form-group col-md-3">
            <label for="exampleInputEmail1">
               Enter IFSC Code</label>
               <asp:TextBox ID="txtIFSCCode" runat="server" type="text" CssClass="form-control" PlaceHolder="Enter IFSC Code" required />
          </div>
          </td>
        </tr>
     </table>
        <br />
        <br />
<table border="0px" cellpadding="4px" cellspacing="4px" align="center" width="180px">
    <tr>
      <td>
        <asp:Button ID="btnSave" runat="server" ValidationGroup="valInsert" Text="Save" OnClick="btnSave_Click" ToolTip="Save" CssClass="btn btn-success" />
      </td>
      <td>
     <asp:Button ID="btnClear" runat="server" Text="Clear" OnClick="btnClear_Click" ToolTip="Clear / Refresh" CssClass="btn btn-default" />
      </td>
<td>
  <asp:Button ID="btnSearch" runat="server" ValidationGroup="valInsert" Text="Search" OnClick="btnSearch_Click" ToolTip="Search" CssClass="btn btn-success" /></td>
    <td>
 <asp:Button ID="btnPrint" runat="server" Text="Print" OnClientClick="return PrintPanel();" ToolTip="Print" CssClass="btn btn-default" />
   </td>
 </tr>
</table>

解决方法:

尝试将formnovalidate放入搜索按钮代码中

<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click" ToolTip="Search" CssClass="btn btn-success" formnovalidate  />
