Re: I need to get the TEXT property of the HyperLink control

Datalist is for viewing data. For this purpose you place the hyperlink in gridview and the on RowDataBound event please write.

protected void grdMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
UploadInfo uploadInfo = new UploadInfo();
LinkButton dr = (LinkButton)e.Row.FindControl("LinkButton1");
}
}

Thank u very much, but I didn't understand, did u mean Hyperlink instead of Linkbutton?

my code used to be like this:

protected void btnApprove_Click(object sender, EventArgs e)<br />
    {<br />
        HyperLink usernameh=(HyperLink) DataList1.FindControl("Hyperlink1");<br />
        string username = HyperLink2.Text;<br />
        SqlDataSource1.UpdateCommand = "UPDATE Users SET newuser ='" + true + "' WHERE (username='"+username+"')";<br />
        SqlDataSource1.Update();<br />
    }

Thanks!

HyperLink usernameh=(HyperLink) DataList1.FindControl("Hyperlink1");
this line will not give you the reference of control.
Because there can be more rows in the list containing hyperlinks.

Access to SQL Server

Hi,

I'm currently developing a large scale ASP .NET application, and so far I've developed it using Access, after research, I don't think Access is going to handle the amount of usage we expect it to get, therefore I'm looking to switch to SQL Server.

Is there anyway I can do this seamlessly and quickly?

Thanks,
Aaron

thereis another thing u\d need to do and that is to alter the db connection from ur application. SQL Server is not accessed the same way as Access is.
but i think it shouldn't be too much of work Smile | :)

Yeah I knew about the code change.

The scenario is, I don't want to spend a couple of thousand on the full SQL, so what I've heard is that you can use SQL Express (has like a 2gb size limit I think) for now, while the project is small, and then when it brings in money, upgrade to the full.

Now the issues are:
1. Does this work / Will I have any issues in changing from Express to the full version?
2. How do I convert Access to SQL Express? (if #1 is ok)

Thanks Smile | :)

offcourse it works and importing data is a very simple task i think

just make a new database in SQL Server and right click on it > All Tasks> Import data> From data providers select MS Access, then select the Access file, give user name password if necessary and carry on with the wizard... I think that should be it Smile | :)

how to get value from hash table

Russell Jones16-Jul-07 1:00

There used to be an SQL Server upsizing wizard that would automatically upgrade from Access to SQL Server.

You would then probably want to do some work to make the best use of SQL server but it should work fine without the extra work.

How to access the values of hidden fileds of form A in form b?
Sessions or querystrings should not be the option! I heard we can access any control of one form in another using persistpage class in 2.0 however iam using 1.1 and c# can i access these hidden fields?

What's done in .NET 2.0 is that an object instance of another page can be created, and that object consumes the data in the Request.Form collection so that you can access the values using that page object.

All the data that was posted to the page is available in the Request.Form collection. You can access those values directly, there is no need to instantiate another page object to do so.

Hi Friend:
Here is code for getting child hashtable value.
//Make main Hash table
Hashtable mainHashTable = new Hashtable();
//Make child Hash Table
Hashtable childHashTable = new Hashtable();
//Add child hash table value
childHashTable.Add("ChildValue", "Mubashir");
//Add child hash table to main hash table
mainHashTable.Add("HashTable", childHashTable);
//Get Child Hash table value
((Hashtable)mainHashTable["HashTable"])["ChildValue"].ToString()

but i have many walu in child hash table like this:-
Dim ConfId As String
Dim meesage As String
Dim SinglNode As System.Xml.XmlNode = xRequests.SelectSingleNode("/cwaEvents/conference")
ConfId = SinglNode.Attributes("confId").InnerText
Dim SinglNode1 As System.Xml.XmlNode = xRequests.SelectSingleNode("/cwaEvents/conference/messageReceived/message/content")
If SinglNode1.InnerText <> "" Then
meesage = SinglNode1.InnerText
'M_MessageTextHTAble = M_MessageHTAble.Item(ConfId)
M_Messagecounter = M_Messagecounter + 1
M_MessageTextHTAble.Add(M_Messagecounter, meesage)
M_MessageHTAble.Remove(ConfId)
M_MessageHTAble.Add(ConfId, M_MessageTextHTAble)
End If
Return M_MessageHTAble

This code works for you. You can add different items in child node.
These item can be of any type.
All you need is type casting.
Lets suppose you added SinglNode of XMLNode type in child hash table.
You shall use this line for getting that object

((XMLNode)((Hashtable)mainHashTable["HashTable"])["ChildValue"]))
This line first get the value of child table then convert it to XMLNode.
You can add multiple different objects in hash table.

//Make main Hash table
Hashtable mainHashTable = new Hashtable();
//Make child Hash Table
Hashtable childHashTable = new Hashtable();
//Add child hash table value
childHashTable.Add("ChildValue", "Mubashir");
//Add child hash table to main hash table
mainHashTable.Add("HashTable", childHashTable);
//Get Child Hash table value
((Hashtable)mainHashTable["HashTable"])["ChildValue"].ToString()

This helpful to extract the whole list of key & values when debugging:

Public Shadows Function ToString(ByVal hashTable As Hashtable) As String
  Dim s As String = String.Empty
  Dim enumerator As IDictionaryEnumerator = hashTable.GetEnumerator()

  While (enumerator.MoveNext())
    s += enumerator.Key & ": " & enumerator.Value & ControlChars.NewLine
  End While
  Return s
End Function

In VB semicolon is not required.
Instead you need to place the semicolon after your alert statement.

This is happening because the text what you have stored in string ID is the same what you are getting. What you need to do is to store the data (what sqlquery is returning) in dataset and then use dataset to display the data.
