I'm having a lot of problems with the gridview bind.
I have a dataset that represents a table of a database.
When I delete or insert a row in the gridview I have the data well inserted or deleted in the db but the gridview duplicates the rows when postbacks the page and i can't understand why. Can someone help me?
Code aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
dbHandler = new WalletManagerDBSqlSrvHandler(DB_SERVER);
shoptype_grid.DataSource = dbHandler.getShopTypes().Tables["ShopType"];
if (!Page.IsPostBack)
{
shoptype_grid.DataBind();
}
formatShopTypeGrid();
}
//eventhandler when a row is inserted
protected void onClickInsertShopType(object sender, EventArgs e)
{
DataTable dtable = dbHandler.getShopTypes().Tables["ShopType"];
DataRow dataRow = dtable.NewRow();
dataRow["ID"] = DateTime.UtcNow.Ticks; /*Generates the ID of the inserted item threw the date and time tick*/
dataRow["Type"] = shopType_txtbox.Text;
dtable.Rows.Add(dataRow);
dbHandler.updateShopType(DatabaseOperation.Insert);
shoptype_grid.DataBind();
}
//eventhandler when a row is deleted
protected void shoptype_grid_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
DataTable dtable = dbHandler.getShopTypes().Tables["ShopType"];
DataRow drow = dtable.Rows[e.RowIndex];
drow.Delete(); //row erased
dbHandler.updateShopType(DatabaseOperation.Delete);
shoptype_grid.DataBind();
}

I think you should clear the view before updating.

inside ASPX
var childWin;
// the following funtion should be used to open the popup
function openWin()
{
childWin = window.open('default.aspx','anycontent','left=400, top=100, height=250, width= 250, status=n o, resizable= no, scrollbars= no, toolbar= no,location= no, menubar= no');
}
I have linkButton inside my page
What I want to is, when I click linkButton then it will call openWin()
thanks in advance

In Page_Load
linkButton1.Attributes.Add("onclick","return openWin()")
assuming you linkButton has an ID="linkButton1"
also, you should add a
return false;
to your openWin() function in order to stop the postback (unless you want ti to, of course, which case return true...)
NB you have a typo in your function#
status=n o
remove the space!
cheers

maybe... try this code from server-side
linkbutton1.Attribute.Add("onclick","openWin();");

Hi Guys,
I installed Visual Studio 2005 on windows 2003 server and I am missing the ASP.NET Item Templates for C# when I try to create a new project.
I have done the following so far but no joy:
1) Close VS 2005
2) Delete the content of folder <instaldirectory>/ Microsoft Visual Studio 8\Common7\IDE\ItemTemplatesCache
3) excute prompt command : devenev.exe /InstallVsTemplates
I also checked the following as well:
open iDE then go TOOLS -> OPTIONS -> Projects and Solutions -> General
in the 'visual studio user items templates location:' edit control add the path to the default installation item templates
(on my system its C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\ItemTemplates\CSharp\1033
cos im using C# :¬)
But no joy.
I spent the whole day today to solve this but still pulling my hair.
Anyone's help will be much appreciated,
happy coding!

Is there a parent-like control available on web? I want to create a custom control which holds two panels. The two panels are containers for objects dragged from the toolbox.
Thnx, Eduard

Why do you think people post their question here... Maybe because they cannot find a solution for their problem. Don't you think I tried google for this question?

Hi all,
I have been assigned a weird project of all times.Its basically a form thats used for creating tables in the database. This is scenario...
There are three panels viz left ,right,bottom. The left panel contains a listbox containing the name of the controls(HTML/Server). Once he selects a control the right panel displays what properties that can be set for the controls and the constraints on that field(Primary key,Identity..).Once properties are set and the user hits add button, the selected control with selected properties is added to the bottom panel.
Once all contols are added,the user fills in the fields generated (textbox,dropdown.datepicker..) and on submit a database table should be created on the server with column names as the entered values and with constraints provided by the user.
Problems ..
>How to go about this stuff(.. only hint will do)
>retaining entered values during postback
>Setting database constraints
any help will be highly appreciated....

 For creating a database table and setting the attributes, why user has to select ASP.NET controls and add it dynamically ?

How about putting the required controls in a DataGrid/GridView ? Then you don't need to bother about managing the state on postbacks. I guess this will be enough.
In first columns put a textbox where user can enter field name, next column could be a dropdown where he can select the attributes like primary key. When add button is pressed, iterate through all the rows, find the controls and create a table creation statement and pass it to ExecuteNonQuery() method.
www.Developerof.NET wrote: retaining entered values during postback
Applicable when you are not using the DataGrid/Gridview method : You can create dynamic controls in any event before viewstate is loaded. Init() would be an ideal place for dynamic controls, and ASP.NET will maintain state for that.
www.Developerof.NET wrote: Setting database constraints
Create a table through design view (Enterprise manager). Right click on the table and choose copy which copies table creation statements to the clip board. Paste it somewhere and learn how constraints are applied through a query. Formulate your query in a similar way.
Hope it helps

Sorry, just jumping in on seeing that: will it maintain custom attributes I add to controls if I do there and not in Load?

Will it be possible to generate dynamic controls on a button click(which causes postback) and add the newly created controls in a panel/div.
Since the init event is called only once i cannot use it on a button click event. Is there any other way round to manage the viewstate

Which is your session mode. inproc ? When will you restore the data ? Immediately after user opens your site, or he/she has to login ? If you are restoring the data immediately after he/she took your site, another user can see the shopping cart of this user if he is using the system within the specified 20 minutes.
Alternatively, you can store the cart details in a table, and access it with user id. Make sure user has logged in and take the records from this table depending on the user id. Put a scheduled job in SQL server which checks this shopping table and removes old data (over than 20mins). This will be ideal and secure.
