Re: GridView on MultiView / View with MenuItems to change Views - the problem - ASP.NET Discussion Boards

Basically, the person who wrote this has no idea how to use .NET. Methods like Ucase should never be used.

I think this belongs in the C# forum, it sure doesn't belong here. It has nothing to do with ASP.NET

hi there,
I have specified users to my web site designed using ASP.net over VB
But actually number of users needed to be larger than they are be added via normal ASP.net configuration, and I need to take them from my database
example : I have a table containing all employees I want them to access my site authenticated and authorized
How can I make them login with there usernames and passwords saved in that table

note : the database used is SQL

I hope that I explained it right

urgent help is needed Smile | :)

There is always something to learn

Surely the built in control can do that ? If not, you need to write your own solution.

Hi,
When I export grid view to excel in asp.net 2.0. It successfully exported but I did localization.
I want to save exported excel file name save in Korean language. When I put file name in Korean language like
protected void ExportGridView(Control grdView, string strFileName)
{

string attachment = "attachment; filename="??".xls";

Response.ClearContent();

Response.AddHeader("content-disposition", attachment);

Response.ContentType = "application/ms-excel";

StringWriter sw = new StringWriter();

HtmlTextWriter htw = new HtmlTextWriter(sw);

grdView.RenderControl(htw);

Response.Write(sw.ToString());

Response.End();

}

The out put comes like “ë¦¬í´.xls” but I want to save like “??.Xls”
How can I do this to save file name as korean language .

Regards

Thanks to Abisodun and Mike for answering my previous post. Both of the answers was directed to the 2nd part of my question. On the first part, I still need help. So - here's it again:

I am using MultiView / View controls which change by MenuItem clicks. Each view has a GridView on it with Edit and Insert features.

The problem is: when the edit button is clicked, the GridView disappears and you need to click on the MenuItem again to see it (it happens evrytime you click edit, update, cancel or insert buttons on the GridView).

Any ideas?

Thanks.

As I said in previous post, you might miss to bind the dataset in your pageload after postback...

Can you show us what you wrote in PageLoad and Edit event?

Hi Michael,

Here's what I'm doing: for the common part of the page, I am using dataset to populate some textbox controls, then for the details part - I'm using GridViews with a SqlDataSources. Each of the GridViews are placed on a View control being changed by MenuItem clicks. Here are some code:
protected void Page_Init(object sender, EventArgs e)
{
projectId = Convert.ToInt32(Session["ClickedId"]);
string [] dataKeys = {"MethodSID"};
conn = new SqlConnection();
// Get the ConnectionString dynamically
conn.ConnectionString = ConfigurationManager.ConnectionStrings["EEM-NEWConnectionString1"].ConnectionString;
dsrcMethods.ConnectionString = conn.ConnectionString;
Parameter param;
dsrcMethods.UpdateCommand = "update tblMethod set MethodName=@MethodName, MethodDesc=@MethodDesc,"
+ "TaxonomicalKeys=@TaxonomicalKeys, TaxonomicalDesc=@TaxonomicalDesc"
+ " where MethodSID=@MethodSID and ProjectID=" + projectId;
dsrcMethods.InsertCommand = "insert into tblMethod (ProjectID, MethodName, MethodDesc, TaxonomicalKeys,"
+ " TaxonomicalDesc) values (" + projectId + ",@MethodName,@MethodDesc,"
+ " @TaxonomicalKeys,@TaxonomicalDesc)";
param = new Parameter("MethodSID", TypeCode.Int32);
dsrcMethods.UpdateParameters.Add(param);
param = new Parameter("MethodName", TypeCode.String);
dsrcMethods.UpdateParameters.Add(param);
dsrcMethods.InsertParameters.Add(param);
param = new Parameter("MethodDesc", TypeCode.String);
dsrcMethods.UpdateParameters.Add(param);
dsrcMethods.InsertParameters.Add(param);
param = new Parameter("TaxonomicalKeys", TypeCode.String);
dsrcMethods.UpdateParameters.Add(param);
dsrcMethods.InsertParameters.Add(param);
param = new Parameter("TaxonomicalDesc", TypeCode.String);
dsrcMethods.UpdateParameters.Add(param);
dsrcMethods.InsertParameters.Add(param);
gvMethods.DataKeyNames = dataKeys;
gvMethods.DataSourceID = dsrcMethods.ID;
}
protected void Page_Load(object sender, EventArgs e)
{
txtID.Focus();
txtID.Enabled = false;
txtTitle.Enabled = false;
txtAbstract.Enabled = false;
txtJust.Enabled = false;
txtSponsor.Enabled = false;
txtStartDate.Enabled = false;
txtStatus.Enabled = false;
txtEndDate.Enabled = false;
txtProgress.Enabled = false;
txtAck.Enabled = false;
if (!Page.IsPostBack)
{
conn.Open();
try
{
txtID.Text = projectId.ToString();
// Create SqlCommand and Parameter to select ProjectID
cmd = new SqlCommand("Select * from tblProject where ProjectSID=@ProjectID", conn);
cmd.Parameters.Add("@ProjectID", SqlDbType.Int);
cmd.Parameters["@ProjectID"].Value = projectId;

dsProject = new DataSet();
da = new SqlDataAdapter(cmd);
da.Fill(dsProject);
cmd.ExecuteReader();
// If there are no records for the user
if (dsProject.Tables[0].Rows.Count == 0)
{
lbl = new Label();
lbl.Text = "<p>You do not have any data for this Project</p>";
Controls.Add(lbl);
}
else
{
txtTitle.Text = dsProject.Tables[0].Rows[0].ItemArray[1].ToString();
txtAbstract.Text = dsProject.Tables[0].Rows[0].ItemArray[2].ToString();
txtJust.Text = dsProject.Tables[0].Rows[0].ItemArray[3].ToString();
txtSponsor.Text = dsProject.Tables[0].Rows[0].ItemArray[4].ToString();
txtStartDate.Text = dsProject.Tables[0].Rows[0].ItemArray[5].ToString();
txtStatus.Text = dsProject.Tables[0].Rows[0].ItemArray[6].ToString();
if (dsProject.Tables[0].Rows[0].ItemArray[7].ToString() == null ||
dsProject.Tables[0].Rows[0].ItemArray[7].ToString() == "")
txtEndDate.Text = "Not Applicable";
else
txtEndDate.Text = dsProject.Tables[0].Rows[0].ItemArray[7].ToString();
txtProgress.Text = dsProject.Tables[0].Rows[0].ItemArray[8].ToString();
txtAck.Text = dsProject.Tables[0].Rows[0].ItemArray[9].ToString();
}
// Cleanup command and connection objects.
dsProject.Dispose();
da.Dispose();
cmd.Dispose();
conn.Close();
}
catch (Exception ex)
{
// Add error handling here for debugging.
Response.Write(ex.Message);
//System.Diagnostics.Trace.WriteLine("[ValidateUser] Exception " + ex.Message);
}
}
}
protected void mnuProjectDetails_MenuItemClick(Object sender, MenuEventArgs e)
{
gvMethods.Focus();

// Get the MenuItem Clicked
int item = Int32.Parse(e.Item.Value);

if (item == 0)
{
conn.Open();
dsrcMethods.SelectCommand = "select * from tblMethod where ProjectID=" + projectId;
conn.Close();
}
else if (item == 1)
{
conn.Open();
dsrcTools.ConnectionString = conn.ConnectionString;
dsrcTools.SelectCommand = "select * from tblTool t, tblMethod m where m.MethodSID=t.MethodID and"
+ " m.ProjectID=" + projectId;
gvTools.DataSourceID = dsrcTools.ID;
conn.Close();
}
MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);
}

Thanks for taking your time and I'm positive that you can find something for me.

Try like that..

In Page_load

<br />
if (!Page.IsPostBack){<br />
  //Getting the data from database<br />
  //Bind the data to Gridview<br />
  // Add this datasource to cache or session (e.g. Cache["mydata"]= dsProject.Table[0]; )<br />
}<br />
else{<br />
  //Re-bind the gridview with datasource from cache. (e.g. GridView1.DataSource = (DataTable)Cache["mydata"];)<br />
}<br />

I know it is embarrassing to ask such a question but how do you navigate in your page?? ie. backward, forward or load a specific url in the same page "I'm using Process.Start("www.url.com");" but I dont want a new page/tab, I want to load it in the same page..

Thank you guys Rose | [Rose]

If you're using Process.Start, it's not going to work when you deploy your site, as it's launching on the server, not the client. Server.Transfer and Response.Redirect are how it's done. The difference is that Server.Transfer doesn't do another round trip and therefore the URL in the users browser does not change.

Use Server.Transfer as Christian has suggested.

Hello Friends,

I am using Asp.net 2.0 with C#.
I have Three textbox ..,txtname,txtAddress,txtphno,and each textbox has Requiredfield Validator.I am inserting Record and show record throuh 2 button ie. Save and ShowRecord button
My problem is when i want show record through Textname textbox putting name(bind through DataReader)
and click on show record then the message comes that other two textbox means txtaddress,txtphon can not blank which i have given in error message.

When i remove validation control then record will be shown in textboxes.

Plz give me some Idea.

parameswar mal

1. I think, you can group the validators in ASP.NET 2.0. I haven't tried using it but read somewhere that it does. so, you probably can try..

OR

2. You can use the custom validators with client-side validation

OR

3. Use Javascript-validation or Server-side validation..

Thanks and Regards,

any body tell me about div why we use this in ASP.net withj some example

Are you a Student or Programmer.

SSK.

Anyone who says sunshine brings happiness has never danced in the rain.

I recommend you buy a basic book on HTML and read it. A div is HTML, it has nothing to do with ASP.NET, excepting that ASP.NET is an engine that creates HTML.

Simply, how do you produce an aspx page and browse it through your iis??
Many thanks guys Rose | [Rose]

You point IIS's root folder to the root of your application, make sure that ASP.NET is installed with IIS ( if you installed VS after IIS, it is ), and that default.aspx is a registered default page, then browse to localhost.

Hello Christian!
When I see your name below my question, I know my question was answered Smile | :)

Thank you for your help, but it's really my first aspx page ever and I didnt think it's that hard to produce and browse a "Hello World!" page, anyhow, the thing is that I have a very simple page that runs nicely by (Ctrl + F5), I publish it and set the publish directory as a virtual directory from my IIS but cant browse it like the other html files, so basically, I'm asking here cuz I have no clue where could be the problem and by googling, I can see it's a common problem with no good answer I could find.

Thanks again Christian, you're really the best Cool | :cool:

If IIS is pointing to the right directory, then I really don't see how it could go wrong, unless you typed 'localhost' with no page name after it and there's no valid default page there.

Hi muammar,
I had this problem few weeks back and I was about to bang my head on the screen but before doing that I played publishing with different name and in different location (i.e; publising directly to wwwwroot or desktop etc then placing it in wwwwrooot) and eventually it worked Big Grin | :-D

I couldn't find the cause which was creating the problem but I successfully run it Smile | :)

ping me if you need more info Smile | :)

Thank you gamzun, it's working just fine now Smile | :)

I would have invited you for dinner tonight but you're not in Yemen.. Thanks again my friend Smile | :)

Hi,

I am using MultiView / View controls which change by MenuItem clicks. Each view has a GridView on it with Edit and Insert features.
The problem is: 1) when the edit button is clicked, the GridView disappears and you need to click on the MenuItem again to see it (it happens evrytime you click edit, update, cancel or insert buttons on the GridView)

2) When you click a MenuItem, the page is posted back and displays from the top again, but I want it to stay at the height where it left so that the users dont have to scroll down again to see the GridView. I can probably use javascript, but I was wondering if there is any asp .net way to fix it?
All ideas are welcome.
Thanx for your help.
