I have a radgrid like below with a column that adds a document to a shopping Cart by clicking a hyperlink. When the document is added the link is hidden so that the document cannot be added again. When the document is removed from the cart, I want to find the row in the radgrid based on the documentId and show the link again. I found how to get row here now I need to hide hyperlink in column. I want to be able to do this client-side.

    
            <telerik:RadGrid ID="rgResults" runat="server">  
        
                                <MasterTableView DataKeyNames="DocumentId" ClientDataKeyNames="DocumentId" DataSourceID="linqSource" 
        
                                    AutoGenerateColumns="false">  
        
                                    <Columns> 
        
                                        <telerik:GridBoundColumn DataField="CaseNumber" HeaderText="Case Number" UniqueName="CaseNumber" /> 
        
                                        <telerik:GridBoundColumn DataField="ParcelId" HeaderText="Parcel Id" UniqueName="ParcelId" /> 
        
                                        <telerik:GridBoundColumn DataField="PartyName" HeaderText="Party Name" UniqueName="PartyName" /> 
        
                                        <telerik:GridTemplateColumn UniqueName="AddDocument" HeaderText="Add">  
        
                                            <ItemTemplate> 
        
                                                <asp:HyperLink ID="lnkAddDoc" runat="server" NavigateUrl='<%#"DocumentCart.aspx?docId=" & Eval("DocumentId") %>'>  
        
                                                    <asp:Image ID="lnkImgAddDoc" runat="server" ImageUrl="~/images/doc.gif" AlternateText="Add to My Documents" /></asp:HyperLink> 
        
                                            </ItemTemplate> 
        
                                            <ItemStyle Width="25px" /> 
        
                                        </telerik:GridTemplateColumn> 
        
                                    </Columns> 
        
                                </MasterTableView> 
        
                            </telerik:RadGrid>

Hello Jterhune,

You can try out the following code to hide or show the hyperlink on the client:
js:

    
             function show()  
        
                {     
        
                   var Rows = $find("<%=rgResults.ClientID %>").get_masterTableView().get_dataItems();  
        
                   for (var i = 0; i < Rows.length; i++)  
        
                   {  
        
                     var row = Rows[i];  
        
                     if(row.getDataKeyValue("DocumentId")=="5")  
        
                     {  
        
                        var hyperlink = row.findElement("lnkAddDoc");  
        
                        hyperlink.style.display="none"; // to hide  
        
                        // hyperlink.style.display="block"; // to show  
        
                     }  
        
                   }    
        
                }

Thanks
Princy.
