I have several GridViews and Tables on a page. Next to a table; I have a button to clear out Text in the TD element's TextBox control "CourseName". When I click on button; it clears out the CourseName field but it also wipes out data from the rest of the control on the page including GridViews. When I put this button in an UpdatePanel; the code behind gets executed but the field "CourseName" wouldn't clear out.
<td><asp:TextBox ID="CourseName" runat="server"></asp:TextBox></td>

To clear the textbox you can use jquery like below
Assign css style to textbox like given below
<asp:TextBox ID="CourseName" class="cssCourseName" runat="server" Text='<%#Eval("Student_Name")%>'></asp:TextBox>Then you can use the jquery code like below
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#btnSubmit").click(function () { //clear the textbox $(".cssCourseName").val(""); }); }); </script>Complete Code
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#btnSubmit").click(function () { //clear the textbox $(".cssCourseName").val(""); }); }); </script> <asp:ScriptManager ID="ScriptManager2" runat="server" /> <asp:Button ID="btnSubmit" runat="server" Text="Clear" /> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"> <Columns> <asp:TemplateField HeaderText="Student_Name"> <ItemTemplate> <asp:TextBox ID="CourseName" class="cssCourseName" runat="server" Text='<%#Eval("Student_Name")%>'></asp:TextBox> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>C#:
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[4] { new DataColumn("Student_Id"), new DataColumn("Student_Name"), new DataColumn("Amount_In_Kitty"), new DataColumn("Require") }); dt.Rows.Add(1, "Student1", 12, 25); dt.Rows.Add(2, "Student2", 34, 29); dt.Rows.Add(3, "Student3", 10, 11); dt.Rows.Add(4, "Student4", 45, 14); GridView1.DataSource = dt; GridView1.DataBind(); }- Marked as answer by Thursday, October 7, 2021 12:00 AM

Hi NJ2,
According to your description and needs, I make a sample that use jQuery to clear the textbox, I think you could through ID to get this element then clear this value.
Sample Code:
<head runat="server"> <title></title> <script src="Scripts/jquery-2.1.0.js"></script> <script> $(function () { $("#<%= btnBlock.ClientID %>").click(function () { debugger; $("#<%= TextBox2.ClientID %>").val(""); $("#<%= TextBox3.ClientID %>").val(""); $("#<%= TextBox4.ClientID %>").val(""); }); }); </script> </head> <body> <form id="form1" runat="server"> <div> <table style="width: 100%" runat="server"> <tr> <th>Value1</th> <th>Value2</th> <th>Value3</th> </tr> <tr> <td> <asp:TextBox ID="TextBox2" runat="server">111</asp:TextBox></td> <td> <asp:TextBox ID="TextBox3" runat="server">222</asp:TextBox></td> <td> <asp:TextBox ID="TextBox4" runat="server">333</asp:TextBox></td> </tr> </table> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Student_Id") %>'></asp:TextBox> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Student_Name" HeaderText="Student_Name" /> <asp:BoundField DataField="Amount_In_Kitty" HeaderText="Amount_In_Kitty" /> <asp:BoundField DataField="Require" HeaderText="Require" /> </Columns> </asp:GridView> <asp:Button ID="btnBlock" class="Button" Text="BlockCalls" runat="server" Width="100px" /> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[4] { new DataColumn("Student_Id"), new DataColumn("Student_Name"), new DataColumn("Amount_In_Kitty"), new DataColumn("Require") }); dt.Rows.Add(1, "Student1", 12, 25); dt.Rows.Add(2, "Student2", 34, 29); dt.Rows.Add(3, "Student3", 10, 11); dt.Rows.Add(4, "Student4", 45, 14); GridView1.DataSource = dt; GridView1.DataBind(); } }Best Regards,
Eric Du
