DataSource Controls :: Making A LINQ To SQL Gridview Column A Clickable Link?
Feb 24, 2010
I have a database table column consisting of text URLs [URL] In my LINQ-to-SQL-driven gridview, I want to make this a clickable link programmatically, with differing link text (e.g. "Link text"). I'm getting close but am missing some key concept. Here's the core of the .vb codebehind:
Dim dctx As New ResourceMod.ResourceModDALDataContext
Dim eleResObj = From eleRes In dctx.Resources Where eleRes.Type = "url" Select siteurl = eleRes.Website
GridView1.DataSource = eleResObj
GridView1.DataBind()
This displays the raw URL in the gridview (i.e. non-clickable). I've experimented with adding an explicit hyperlink column a la [URL](setting AutoGenerateColumns false etc.), but haven't yet figured out how to assign the asp:hyperlink Text and NavigateUrl fields with the anonymous-type object eleResObj. Using a field construct such as Text='<%# Eval("siteurl") %>' isn't working, presumably a scope issue. Is a LinqDataSource needed in this case, and if so, how would that affect the original LINQ query?

I have a GridView which is linked to the database via SqlDataSource.
What I would like to do is to make each row of a designated column clickable. Once the user has clicked on a row, the application should postback to another page to allow the user to read all the details of that row.
The effect should be as we can see in this post: if you go to "mypost", you have a list of posts and then when you click on one of them you are able to see the details of that.
I read lots of posts that are using, however, other methods such as datalist + dataset controls etc.

I have a gridview that includes a checkbox colum (Item Tempate).I need to be able to select row but when mouse is over checkbox column it should not be clickable. Is this possible?Think of it as an Inbox type gridview where checkbox is used for deleteing messages but when you click on subject or name it will show the message. I need the same functionality.

I have a gridview setup and have the select button enabled. I also have a gridview that doesnt have a select button enabled..
On them both, if its possible, i would like to make the row itself selectable instead of just enabling the select button.

Created a asp page using vbscript to calculate a value (works fine). I'd like to return the value as a clickable link, which would obviously redirect the user somewhere else.

I have gridviwe having 2 columns:
1) DocNumber 2)Title
query select docnumber,title from tbl_docs.
BindwithGridviwe(sql);
Now the issue is that that every document doesn't has document number. I want to make invisible the docuNumber column of the grid viwe if all values in the docNumber retrieved are null.for example:
docnumber tite
null Document 1
null Document 2
null doucment 3
null document 4
if returned result match above where all docnumber are null then make the gridviwe docnumber column ivisible eslemake the greidviwe column visible.

I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.I have tried the following but it doesn't seem to work? hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c#
DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here.

i need to send a clickable link to many people via mail using vb.net .
Dim smtp As New SmtpClient
email = "emailaddress@xyz.org
Dim mm As New MailMessage("test", email)
mm.Subject = "test"
mm.Body = "http://www.mywebsite.org/mypage.aspx" & "<br><br>" & "greetings"
mm.IsBodyHtml = True
smtp.Send(mm)
This code works perfectly when the mail is read with Outlook. People get a clickable link which brings them to the right page. But the same mail read in Hotmail (or any webmail site) provides a non-clickable link.
I also tried with:
mm.Body = "http://www.mywebsite.org/mypage.aspx" & chr(9) & chr(13) & "greetings"
mm.IsBodyHtml = False
but then, i get no clickable link in Outlook.
How can i send a clickable link which works with Outlook and Hotmail?

I am a new coder trying to experiment with jquery for my first time. I'm trying to setup a simple datalist that might be used to display comments for an item. I want a clickable link (per datalist row) to drop down a panel (per datalist row) that has comment text. so the user looks at row 1, clicks it's link to read comments, and the comments panel drops down. they scroll down and do the same for the next item.
so far i have the below code as a small test page, but it's not working. nothing happens basically. I tried the clientID thing because it seems i need that to deal with the auto-generated ID's .NET will assign panels as it's rendered, but i'm not sure if i'm doing it right.

I have an accessdatasource that pulls several columns from my users table including [userID]. Then I have a gridview that displays all this information by autofilling the columns. Finally I have added a column that I want to link to viewUser.aspx?userID=####. The #### would of course be from the query.
Here's my column that I've added:
<Columns>
<asp:HyperlinkField datatextfield="View User"
datanavigateurlfields="userID"
datanavigateurlformatstring="viewUser.aspx?userID={0}"
headertext="Link"
target="_blank" />
</Columns>
This is my first time using this so I'm not sure what's wrong. I don't understand the '{0}' part and that's also where the problem lies. On the viewUser page when I print the querystring("userID") it just shows {0} as expected. How do I get my userID in there?

I am trying to create a multi column listbox by combining fields in Linq select statement, as Let Name = Last + First. The problem is how to pad the Last column with spaces as you would in SQL using REPLICATE so when I bind the listbox to the data, it looks like two columns.

I have a table being generated in an ASP.net web app. The table has 4 columns. Currently each cell of each row can be clicked to get more detailed info. However, I do not want the first and the last cell in each row to be clickable. How can I make it so that only the first second and third cell can be clicked?
Below is some of the code (from the .cs file):
if(e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.BackColor = TRADER_BACKCOLOR;
e.Row.Cells[0].Font.Bold = true;
e.Row.Attributes.Add("onmouseover", "style.backgroundColor = 'Silver'");
e.Row.Attributes.Add("onmouseout", "style.backgroundColor = '" + TRADER_HEX + "'");
e.Row.Attributes.Add("onclick", "RowClick(this, '" + e.Row.Cells[0].Text + "');");
From the .aspx file:
function RowClick(caller, id)
{
if(document.getElementById(id).style.display == "block")
{
if(last != "" && parent == id)
{
HideDetailed();
}
document.getElementById(id).style.display = "none";
}
else
{
document.getElementById(id).style.display = "block";
}
}

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

I continue to get compiler errors. I have a Gridview (with Delete and Edit buttons) that I populate via LINQ with e-mail addresses. When they hit the delete button I want to use LINQ to delete the row from the table based on the GridView DataKey. If I use Response.Write(ID) it will show the ID number for the Email that I want to delete.Here is the error:
"Error 2 The best overloaded method match for 'System.Data.Linq.Table<Email>.DeleteOnSubmit(Email)' has some invalid arguments C:InetpubwwwrootXXXXXXXXXEditEmail.aspx.cs 53 13 C:...XXXX"

I want to display a Gridview of Patients before I submit them to the database. Is there a way(better way), other then List<Patients>, to bind a list to a GridView.
I am using Linq to SQL and I have a DAL with the Patients table inside. I create a new list of Patients
[Code]....
Now the problem is I can't use a Linqdatasource or Objectdatasource to link to the GridView as no data is in the db yet. The only thing that works is GridView.DataSource = _patients; but I lose all automatic formatting and as far as I can tell it is going to be a pain to format manually. It would seem I should be able to somehow link my object _patients to an one of the datasourses so I would have formatting and all.
