Re: can we store viewstate in masterpage?

But where it will get the Id ... In server side ??

Id should be stored at least somewhere to communicate. Do you think only a property can make things ok. Every time a web request is made a new object of the whole page will be created. If you open a new tab, there will be no communication between the original page(Even session is different)

So it will always hold the default value of the property. Viewstate will be refreshed for every page, so it cant get the values that you created in another page.

Anyways...
thanks for your appreciation. But I am still not sure what you are upto...

Best wishes.

Create the public property in Master page.
Cast the master page in content page

MasterPage mymasterpage = Page.Master as MyMasterPage;

Use the property in content page to access the customer name.

Response.Write(mymasterpage.CustomerName);

Try it, if it is working

I dont want to make changes in all the content pages because there are around 40-50 pages.It's tedious to incorporate this changes to all the files.

Is there a way by which i have to modify only the master page?

AFAIK, html image control couldnt be rotated. You can define the size of the img but cant rotate.

To do this, you need to rotate the image in the server and produce another image and show it in browser. Use graphics object to draw a new image rotating it in an angle and show it in browser.

This article could be a good help for you :
Image Rotation in .NET[^]

After you rotate the image, show it using img tag.

On the other hand:
If you want to rotate in browser itself, you might use Flash / silverlight which are capable of doing this.

Hope you got this.

I think this javascript uses moveto function to actually rotate an image.

Use this Javascript

I think you can do this without Flash and Silverlight.

If you are sure that the resultant string is in valid XML format, just load it to XmlDocument and use XPath to get the required values. Other option is to use regular expression and look for the text.

Work with XmlDocument.LoadXml(string xml)[^] overload.

If you place a wrapper to all the tr's it will load easily in XMLDocument / XDocument.

Just take the table tag which wrap around all the entries.

Use XElement.Load(your html string) to get the xml loaded.
Now search the elements using Linq to XML.

Just use client side button.

When onclick to button, make an ajax call to the server(might be a dedicated handler) and change the src or img tag.

Here is a code project in asp.net.
i have to insert dynamically create rows in a table name : [Pin_Generate]
The number of rows are inserted by the user and then submit and it create that number of rows in that table.

But it cannot be done when its going 2nd time in a loop...

<br />
for (i = 1; i <= Convert.ToInt32(EnterByUserTextBox.Text); i++)<br />
        {<br />
            getNum();<br />
<br />
            scomm1.Parameters.AddWithValue("@pid_no", lblprint_id.Text);<br />
            scomm1.Parameters.AddWithValue("@pserial_no", lblserial_no.Text);<br />
            scomm1.Parameters.AddWithValue("@ppassword", lblpassword.Text);<br />
<br />
            sconn1.Open();<br />
            int x = 0;<br />
            x=scomm1.ExecuteNonQuery();  // when i=2, the error occurs here.           <br />
            sconn1.Close();<br />
<br />
          <br />
            if (x > 0)<br />
            {<br />
                <br />
                lblmsg.Text = "Successfully Created";<br />
                update();<br />
<br />
            }<br />

Welcome to CodeProject! Please read the forum guidelines[^] to learn how to ask better questions. People here do voluntary help and specifying urgent in the message won't help you to get answers. It is considered as rude.

To answer your question: what error are you getting? What getNum() function is doing?

There are few problems in your code. You are adding parameters in each iteration which is not correct. If you want to insert the same value N times, you don't have to open and close the database connection each time. Open it once, call ExecuteNonQuery() N times and close the connection. Here is the code after few refactorings.

int n;
if(!int.TryParse(EnterByUserTextBox.Text, out n))
{
    // Inform user about invalid input and return
}

// using block avoids resource leaks
using(SqlConnection sconn1 = new SqlConnection(connectionstring))
using(SqlCommand scomm1 = sconn1.CreateCommand())
{
     // Adding parameters
     scomm1.Parameters.AddWithValue("@pid_no", lblprint_id.Text);
     scomm1.Parameters.AddWithValue("@pserial_no", lblserial_no.Text);
     scomm1.Parameters.AddWithValue("@ppassword", lblpassword.Text);
     try
     {
         sconn1.Open();
         for (i = 1; i <= n; i++)
         {
              scomm1.ExecuteNonQuery();
         }
         sconn1.Close();
         lblmsg.Text = "Successfully Created";
         update();
     }
     catch(Exception ex)  // always catch specific exceptions than the base System.Exception
     {
         lblmsg.Text = "Please Try Again" + ex.ToString();
     }
}

Thanks a lot for your reply

I created a new website. The files are inside the visualstudio2005\projects\website1 and visualstudio2005\websites\website1

I have copied the files(.sln and .suo) in visualstudio2005\projects\website1\ to the visualstudio2005\websites\website1\ and then open the project. Its working fine.

But if i copy the website1 folder from visualstudio2005\websites\website1\ to c: drive.. i cannot open the project. It is saying one or more files cannot be loaded. If I put inside Websites folder in c drive then its working.. How can i solve this

The error showing is

One or more projects in the solution could not be loaded for the following reason(s):<br />
<br />
The project file or web has been moved, renamed or is not on your computer<br />
<br />
These projects will be labelled as unavailable in solution explorer, Expand the project node to show the reason the <br />
<br />
project could not be loaded.

Hope you understand
