ASP.NET

I have a datagrid with various BoundColumns and HyperLinkColumns.
All of the columns work great. The problem is that I am creating a list for data entry. If the data has already been entered I want to disable the Entry Hyperlink and Enable the View/Edit Hyperlink, and visa versa if the entry has not been made I want the Entry HyperLink to be Enabled and the View/Edit HyperLink to be Disabled. If there was a way to create an ID for the column I could handle it in the ItemDataBound Event in the behind code, but I have not found a way to create an ID field for the HyperLinkColumn. Could someone assist with a code sample for ASP.NET...

It could be done easily using this :

.disabledLink
{
color: #333;
text-decoration : none;
cursor: default;
}

Use this Javascript to do this in client side.

function disablelink(linkID)
{
var hlink = document.getElementById(linkID);
if(!hlink)
return;

hlink.href = "#";
hlink.className = "disableLink";
}

or in ItemDataBound use :

ctrl.CssClass = "disabledLink";
ctrl.Href = "#";

It will be disabled. Cool | :cool:

Why do you require to create ID. If you place the server side ID, you might use ClientId to get what id is generated in the client. Wink | ;)

protected void gvPaymentDetails_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            GridViewRow gvr = e.Row;
            
                      
            if (gvr.Cells[5].Text != "&nbsp;" || gvr.Cells[6].Text != "&nbsp;" || gvr.Cells[8].Text != "0")
            {
                ((LinkButton)(e.Row.FindControl("lbEdit"))).Enabled = false;
                ((LinkButton)(e.Row.FindControl("lbEntry"))).Enabled = True;
            }
            else
            {
             ((LinkButton)(e.Row.FindControl("lbEdit"))).Enabled = True;
             ((LinkButton)(e.Row.FindControl("lbEntry"))).Enabled =False;

            }
            

           

        }
    }

I am using this code in my appliction for edit and add button.

Will ASP.NEt treat the LinkButton the same as the HyperlinkColumn with all of the same properties like DataNavigateUrlField and DataNavigateUrlFormatString?

i think it will work in hyperlink columns 2 but why dont u use this code

<Columns>
            <asp:TemplateColumn>
                <ItemTemplate>
                    <asp:LinkButton ID="lnkEdit" runat="server">Edit</asp:LinkButton>
                    <asp:LinkButton ID="lnkView" runat="server">View</asp:LinkButton>
                </ItemTemplate>
            </asp:TemplateColumn>
        </Columns>

use itemtemplate for hyperlinks

Where do you handle the actual navigational link and column header information?

<asp:TemplateField>
                                                   <ItemTemplate>

                                                       <asp:LinkButton ID="lbEdit" runat="server" Text="Edit" OnClick="lbEdit_Click"></asp:LinkButton>
                                                   </ItemTemplate>
                                               </asp:TemplateField>

i am redirecting from aspx only.

LinkButton btn = sender as LinkButton;
       GridViewRow gvr = btn.NamingContainer as GridViewRow;
       string docNo = gvr.Cells[0].Text;

so this way i am fetching row datakey

Wouldn't you have to handle that in the Code Behind...
My predecessor developed this is VB

I like the looks of this implementation except that it feel like a total rewrite of the ASP page because the page binds data to both BoundColumns and HyperLinkColumns.
To date I have not attempted to bind data to a LinkButton. Is this possible? or would I Have to move all of the naturally bound data to the ItemDataBound method and then launch the enbedded JavaScript from the ItemCommand method?
