仅在一个按钮单击时启用必填字段验证(Enable Required Field Validation In Only One Button Click)

我在asp.net c＃中开发应用程序，因为我有一个问题。问题是我在asp.net页面中有三个字段，因为它有银行名称，分支和IFSC代码，当我点击保存按钮时，这三个字段是强制填写的，

但当我点击搜索和清除按钮时，它应该要求填写这些字段。如何在单击其他按钮时限制此项

“请填写此字段”..

假设我只搜索sbi银行，它会要求进入每个领域。

我的代码输入银行

</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>

i am developing application in asp.net c#, in that i have a problem . the problem is i have three fields in a asp.net page, in that it having Bank Name, Branch, and IFSC Code, these three is mandatory to fill when i click save button,

but when i click search & clear button also it should ask to fill these fields. how to restrict this when click other buttons
