That would depend on your need, usage & comfort-ability with a given third party. I would say it would be individual's choice from below list:
1. DevExpress
2. Infragistic
3. Telerik
Have a look at all three, evaluate by yourself. All have good controls, knowledge-base and support forums.

I'm a big fan of DeveloperExpress.

Their Grid control is amazing along with their other tools.
BTW: I've actually met some of the engineers at a meet & greet in NYC about a year ago ... very cool to talk with them.
My 2 cents.

I think Telerik is the best!
its rad grid have a wonderful Facilities filtering for every column with to many filter, and grouping by drag and drop , handling too many scenario , and perfect examples and documents!

"Best" is of course different depending on what you need. InterSoft[^] has a great grid and has a batch update feature which allows you to add as much as you like client side, or delete of course, and then process in a batch.
There are only 10 types of people in the world, those who understand binary and those who don't.

Quote: hi,
I am using an aspxgridview and two checkboxes(for header and dataitem).When I check header checkbox I want to check all checkbox.I am also using java script code.essentially, I can do this, but I must check header checkbox twice times.I didnt understand why it is happening.ı am writing this code checkbox_checked event and header checkbox's autopostpak is true. When I used normal gridview I didnt have any problem I could do this without problem.,
<script language="javascript" type="text/javascript">
function SelectAll(id) {
var IsChecked = id.checked;
var Chk = id;
// Parent = document.getElementById('GrdPerliste');
Parent = document.getElementById('<% = GrdPerliste.ClientID%>');
var items = Parent.getElementsByTagName('input');
for (i = 0; i < items.length; i++) {
var deneme = items[i].type;
if (items[i].id != Chk && items[i].type == "checkbox") {
if (items[i].checked != IsChecked)
{ items[i].click(); }
}
}
}
</script>
protected void Checksec_CheckedChanged2(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
GridViewHeaderTemplateContainer bulundugucontainer = (GridViewHeaderTemplateContainer)chk.NamingContainer;
((CheckBox)bulundugucontainer.FindControl("Checksec")).Attributes.Add("onclick", "javascript:SelectAll('" + ((CheckBox)bulundugucontainer.FindControl("Checksec")).ClientID + "')");
}

First, your issue/flow of why two clicks
This happens as you add the onclick attribute in checkchanged event. So, for a fresh page, first click postbacks and you register javaScript code for checkbox. Second click uses this registered JS method and you get what you want.
You can do it without any postback or server event - just using a Javascript. You need to attach the JS code to checkbox in Grid's RowDataBound event where very rowbind is called. Once this is done, single click would work.
Have a look at these:
Using JavaScript with ASP.Net GridView Control[^]
Using jQuery without RowDataBound code[^]

How to get control values in itemupdating event of detailsview.

hello friends place can anyone help me...
I need to get the data from BAPI and display that data in the ASP.NET Crystal Report....
|
|
|
|
|
I had to Google BAPI to figure out what your referring to. Upon searching for the context of BAPI, I came across many forums that answer how to connect to the SAP database using asp.net.
You should try the SAP website or forum for using asp.net to connect to SAP. As far as the crystal reports goes, I thought that was a windows report module.

I have a C#.net 2010 web form application that I need to add two tables to the database. This application uses linq to sql. Can you tell me if I want to add these two new tables to the sql server 2008 r2 database, do I
1. Need to remove the original .dbml file and recreate the .dbml file?
2. I would think I can just add two tables to the database and somehow refresh the existing .dbml file. If this possible?
Whatever your answer is to the question, can you tell me how to solve this problem?
|

|

classy_dog,
double click on the dbml file and on the view menu choose server explorer add a link to the server your database is modeled from (you may already have one), you can click in any white space in the dbml diagram and look at the properties->connection->connection string to get the connection string. Once you have the server connection you can just drag the table(s) into the diagram.

As explained here http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.datakeys.aspx[^]
When the DataKeyNames property is set, the GridView control automatically creates a DataKey object for each row in the control. The DataKey object contains the values of the field or fields specified in the DataKeyNames property. The DataKey objects are then added to the control's DataKeys collection. Use the DataKeys property to retrieve the DataKey object for a specific data row in the GridView control.
The reason for null reference exception in the above code could be due to not setting the DataKeyNames property but accessing the DataKeys[e.RowIndex] value at
customer.Update(Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values[0].ToString())
Try setting the DataKeyNames as shown in above reference like
datakeynames="CustomerID"
|
|
|
|
|
you can't use .ToString() method and set it to a null value,
GridView1.DataKeys[e.RowIndex].Values[0] is passing a null value!
set DataKeys for your gridview!

The ajax model popup extender has a habit of resetting back to hidden during postback.
You have to modelPopup.show() the extender in your button function to keep it in block mode, to keep it visible.

Procedure or function expects parameter that was not supplied why it arise and if arise how to resolve it

Supply the expected parameter.
Given that you have not shown the line of code in question we have no way of knowing the answer. If it's a call to a system API method then take a look at the documentation to find out why. If it is code belonging to some other developer then ask them.

OK I am supplying my code with stored proc here:
My stored proc:
USE [UniqueCorp]
GO
/****** Object: StoredProcedure [dbo].[uspUpdateUser_Step2] Script Date: 06/05/2012 12:12:38 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[uspUpdateUser_Step2]
@userID uniqueidentifier,
@Username nvarchar(50),
@CompanyName nvarchar(50),
@Address nvarchar(100),
@Country nvarchar(50),
@State nvarchar(50) = '',
@City nvarchar(50) = '',
@MobileNo nvarchar(50) = '',
@TelephoneNo nvarchar(50) = '',
@Password nvarchar(50)
AS
set nocount on;
IF Exists (SELECT [ID] FROM dbo.Users WHERE [ID] = @userID)
begin
update dbo.Users
set
UserName=@Username,
CompanyName=@CompanyName,
[Address]=@Address,
Country=@Country,
[State]=@State,
City=@City,
Mobileno=@MobileNo,
TelephoneNo=@TelephoneNo,
Password=@Password
WHERE [ID] = @userID
end
GO
and the code behind is this.......
public static int AddUpdateUser(Users user)
{
SqlParameter prmUserId = new SqlParameter("@userID", SqlDbType.UniqueIdentifier);
prmUserId.Value = user.ID;
SqlParameter prmUsername = new SqlParameter("@Username", SqlDbType.NVarChar, 50);
prmUsername.Value = user.UserName;
SqlParameter prmCompanyName = new SqlParameter("@CompanyName", SqlDbType.NVarChar, 50);
prmUsername.Value = user.CompanyName;
SqlParameter prmAddress = new SqlParameter("@Address", SqlDbType.NVarChar, 100);
prmUsername.Value = user.Address;
SqlParameter prmCountry = new SqlParameter("@Country", SqlDbType.NVarChar, 50);
prmUsername.Value = user.Country;
SqlParameter prmState = new SqlParameter("@State", SqlDbType.NVarChar, 50);
prmUsername.Value = user.State;
SqlParameter prmCity = new SqlParameter("@City", SqlDbType.NVarChar, 50);
prmUsername.Value = user.City;
SqlParameter prmMobileNo = new SqlParameter("@MobileNo", SqlDbType.Int, 50);
prmUsername.Value = user.MobileNo;
SqlParameter prmTelephoneNo = new SqlParameter("@TelephoneNo", SqlDbType.Int, 50);
prmUsername.Value = user.TelephoneNo;
SqlParameter prmPassword = new SqlParameter("@Password", SqlDbType.NVarChar, 50);
prmUsername.Value = user.Password;
return DataAccessObject.Execute("uspUpdateUser_Step2",prmUserId, prmUsername, prmCompanyName, prmAddress, prmCountry, prmState, prmCity, prmMobileNo, prmTelephoneNo,prmPassword);
}
Please help me the problem is still there...
Procedure or function expects parameter @Username That was not supplied.....
But i debug and confirm dat value is gone to the parameter @Username.So now i hav no idea about this ....

Firstly, this is a database problem and nothing to do with ASP.NET, so it is in the wrong forum. Secondly, you have given no indication where the error occurs. Thirdly, please use the correct <pre> tags around your code so it is readable, like this:
USE [UniqueCorp]
GO
SET ANSI_NULLS ON
GO
...
|
|
|
|
|
we have to assign default value as NULL
Create Procedure Sp_name
@Input1 varchar(100)=NULL
AS
BEGIn
//main Code
END
