View 3 RepliesI am having problems in retaining the string variable which I defined on the top of my scoop, everytime when page loads the string value becomes null. below is the snippet of the code:
public partial class Caravan_For_Sale : System.Web.UI.Page

string check;
PagedDataSource pds = new PagedDataSource(); //paging

View 9 RepliesI want to open a aspx page in new window.
I am openning a web page using JavaScript open .
StringBuilder cstext3 = new StringBuilder();
cstext3.Append("<script type=text/javascript> function OpenPreviewPage() {");
cstext3.Append("open('Preview.aspx');");
cstext3.Append("} </script>");
And executing following at button click on .cs page
protected void btnPreview_Click(object sender, ImageClickEventArgs e)
{
/*This will call the OpenPreviewPage method of java script from .cs file */
string javaScript =
"<script language=JavaScript>
" +
"OpenPreviewPage();
" +
"</script>";
RegisterStartupScript("ShowPreviewPage", javaScript);
}
The problem is the PreviousPage tag in preview page is null.
repPFareDetail = PreviousPage.FindControl("repFareDetail") as Repeater;
Is there any other way to open the aspx in new window by retaining the PreviousPage.FindControl method.
this is probably very simple but I'm tearing my hair out!I'm using the FindControl method to try and grab the text in a textbox inside a DetailsView Template Field and display it on a label. Here is my code:
[Code]....
The word text has a squiggle underneath though and it causes an error as "System.Web.UI.Control' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)". I know the problem is that I'm treating this Control as a TextBox when it isn't, it's a Control. So how do I get from Control to TextBox so I can take the String and use it in code?
There is a string in which email addresses are there like
as@as.com;df@fd.com;gh@df.com
I want that it will pick email address one by one and fill it to 'To' and send message one by one.
I ahve a solution with a few dll projects, a winforms testbed and a WCF webservice project. In the data project, I have a base class that does the following:
public class BaseDAO
{
private const string CONNECTION_NAME = "OracleConnectionString";
protected static string GetConnectionString()
{
ConnectionStringSettingsCollection settings =
ConfigurationManager.ConnectionStrings;
string conStr = "";
if (settings != null)
{
foreach(ConnectionStringSettings setting in settings)
{
if (setting.Name == CONNECTION_NAME)
{
conStr = setting.ConnectionString;
}
}
return conStr;
}
else
{
throw new NotImplementedException("The connction string can't be found");
}
}
You might ask, why do I need to loop and check the name against a constant? Well, I have defined the connection string in the service project's web.config, but this above code always find two connection strings, one is a sqlexpress which I guess is a default database of some sort. So, to separate that one against the one I really use, I have to loop through all entries and pick out the one I plan to use. How do I prevent this? Is there a better way to fetch the connection string from the data project?
I have a masterpage with three ContentPlaceHolder and a page derive from it.
Let's call the page derive from it as "PageFrom", the "PageFrom" has a GridView.
Each row in the GridView has a linkbutton which do a cross page postback to another page, "PageTo"
And I am trying to grab any control in the "PageFrom"
I have tried PreviousPage.FindControl() and PreviousPage.Master.FindControl(), none of them works.
The master page code

The PageFrom

I am trying to add a string to an SQL statement based on whether an asp:checkbox is checked. Below is what I have, and it isnt working.
I know I could set comm inside the if statement, but I imagine there is a way just to add a variable string to the SQL.
Quote:
string IndCBSQL;
if (iIndividualsCheckBox.Checked)
{
IndCBSQL = "AND CMMaster.CONSTTYPE LIKE 'Individual'";

I know that most people store the Database connection string inside the web.config file.
But my question is if we move the web.config file from dev to prod then we have to change the connection everytime.
how can we have a connection string that we do not have to change when we move our code from dev to prod.
We can store Connection String in Web.config file in two ways One is
<connectionStrings>
<clear/>
<add name="LocalSqlServer"
connectionString="Data Source=(local);Initial Catalog=aspnetdb;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
Other One is
<appSettings>
<add key="ConnectionString"
value="server=localhost;database=Northwind;uid=sa;password=secret;" />
</appSettings>
Now I want to know What is difference between these two approach? Which one is better way? What are their limitations?
UPDATE:Can you explain that <connectionString> has any significant advantage over <appSetting>?

Ok, so it's easy in VB, but I can't figure it out in C#:
SqlCommand cmd = new SqlCommand("SELECT COUNT(*) FROM tblUsers WHERE username = '" & username & "'", cn);
This throws
CS0019: Operator '&' cannot be applied to operands of type 'string' and 'string'
<img src="http://track.opicle.com/aff_l?offer_id=2193&adv_sub=LEAD_ID" width="1" height="1" />
var x ;
x Should be replace at the place of LEAD_ID
<img src="http://track.opicle.com/aff_l?offer_id=2193&adv_sub=x" width="1" height="1" />
Meas var x will replace at the place of Lead_ID
