by Updated September 19, 2018

Here's how you can find the text of a particular TextBox witnin an ASP.NET GridView row and then Select and Copy the text to Clipboard with Javascript.

First put the following javascript in the HTML of your page (either in HEAD of your html page or somewhere above the GridView control):

        <script type="text/javascript"> 
            //<![CDATA[

            function SelectTextandCopyToClipboard(currentTextBox) {

            var txtNameUrl;

            //Find the GridView Row using the TextBox reference.
            var row = currentTextBox.parentNode.parentNode;

            //Fetch all controls in GridView Row.
            var controls = row.getElementsByTagName("*");

            //Loop through the fetched controls.
            for (var i = 0; i < controls.length; i++) {

                //Find the TextBox control.
                if (controls[i].id.indexOf("RecommendUrlTextBox") != -1) {
                    txtNameUrl = controls[i];
                }
            }

            // Select text
            txtNameUrl.select();
            // Copy to clipboard
            document.execCommand('copy');

        }
         //]]>
    </script>  

 

Here's a sample GridView that corresponds to the Javascript above to Copy inner text from a single TextBox within the GridView

             <asp:GridView ID="LinksGridView" runat="server" OnRowDataBound="LinksGridView_RowDataBound"
                 DataKeyNames="LinkId" DataSourceID="LinksDataSource" PageSize="50">
                 <Columns>
                     <asp:BoundField DataField="LinkId" HeaderText="Id" InsertVisible="False"
                         ReadOnly="True" SortExpression="LinkId" />
                     <asp:TemplateField HeaderText="Link URL" HeaderStyle-HorizontalAlign="center">
                           <ItemTemplate>
                            <asp:TextBox ID="RecommendUrlTextBox" runat="server" Text="These words are will be selected." onclick="SelectTextandCopyToClipboard(this);" Width="200px" BackColor="#FDFEFF" ToolTip="Click to Copy URL"></asp:TextBox>
                          </ItemTemplate>
                     </asp:TemplateField>

                 </Columns>
