I am assuming you are using VS2005 here.
If you have your grid bound to a datasource then use the grids "Edit Columns" property in design view to remove the columns from the datasource that you dont want to appear in your grid.
monuSaini wrote: And i want to add edit button , delete button and an dropdownlist box in gridview
You can add unbound columns which contain buttons etc again by using the Edit Columns option in design view.
If you need to access any of the controls you add then there are many articles on the web explaining how to do this. Take a look at the following article within the code project articles section.
http://www.codeproject.com/dotnet/AccessingControlsInsideGr.asp[^]
I hope this helps in some way.

Try looking at this page:
http://msdn2.microsoft.com/en-us/library/zkatshfa.aspx[^]
It explains how to add unbound columns to a gridview through code. There is also a link on the page which will take you to a step by step guide of how to add buttons through the designer.
If this is no help then here are the steps i followed:
1. Create a new windows forms application.
2. Add a data gridview to the form and bind it to a data source. (Customers table on the Northwind database)
3. Right click on the grid view and select Edit Columns.
4. Remove the columns you dont want to display from the data source.
5. Right click the grid view and select Edit Columns.
6. Click the Add button.
7. On the Add Column window select the "unbound column" option box.
8. Change the Type combo box to be DataGridViewButtonColumn
You now have a column which will contain a button.
Unless there is something i am mis-understanding then this should do what you were asking.

// Fill dataTableObject with your desired data
// and bind it to your grid view
datagridview1.datasource=dataTableObject;
and if you're doing in asp.net then,
gridview1.datasource=dataTableObject;
gridview1.databind();

Read the build output and it'll tell you how to correct it:
int results = com.ExecuteScalar();

There is a lexical typo error in the string literal 'errror'.

ExecuteScalar is a method so it needs () at the end

Hi. Im making a database application for viewing/editing/searching. Im using the DevAge SourceGrid for database handling. I was told to ask on another forum becouse it was not a SourceGrid related problem. It works as it should in the its current state, but it need to evolve to be able to support more Tabs with grids then only one at a time. so I thought I should solve this dynamicly. I have writen a function that can be used to fill new Tabs, with a Panel and inside this Panel two datagrids. This function can be used to fill these dynamicly created datagrids and fill them with diffrent information from diffrent dataset's.
The problem is Im not sure how to determin what dynamicly created datagrid is currently viewed, and there for be able to be controlled and modefied by new values or what ever should happend with database releated functions as refresh,fitler,update info and so forth.
It is the "maDynamicDataGrid" I belive, I need to know the diffrence between these dynamicly created datagrids.
This is the response line I got before i got here.
"You must read the Tab structure and iterate on all the controls (Tab->Panel->Grid ...)"
Im posting code of the function for creating the dynamic Tab, with the grids.

I have created an enumeration in the class named abc.cs and placed that in the App_Code directory
<br />
public enum MyEnum<br />
{<br />
alfa = 1,<br />
beta = 2,<br />
gamma = 3<br />
};<br />
I have to access this and display in the list control of a webform .
can anyone help me with the corresponding syntax.
i will be thankful to you.
Sebastian

You should place it within a namespace:
namespace MyProject.MyEnums
{
public enum MyEnum
{
alfa = 1,
beta = 2,
gamma = 3
};
}
then, you should be able to access it anywhere. To get it's value in your aspx, you need a code block:
<%# MyProject.MyEnums.MyEnum.alfa %>
for example.
In your code behind you can put a using statement for the namespace, or access the enum by the full name.

Hi,
Thank you very much. Everytime you are there to help me.
In this scenario i have to know all the members of the enum. but if i use a file to store the values the updations will reflect in the webpage automatically. is n't it?
is there any better alternatives?
Thanks once again

Im very new in c#, how do i create an application form with labels and text boxes, listbox, submit and clear in either windows forms or console
csanda
|
|
|
|

You are definately new. A console app doesn't have labels or text boxes. In fact, doing this is trival, and doesn't even require code. However, before doing this, you should work through a book that teaches C#, and learn the language, on the console. Either way, your question can't be answered in a forum post, you need to buy some sort of C# book and work through it.

Hi,
Is there a quick and simple way to get a UML diagram of your classes using Visual C# express? (2k5)

I am not sure in 2k5 but in 2k3 Go to: Project-> Visio UML-> Reverse Engeinner.
I think it may help you

Hi,
I wish to set a registry value to record where my programs database was installed.
This folder will change depending on whether it is installed for "Only Me" or "All users".
I know about the [AppDataFolder] and the [CommonAppDataFolder] and can use them but how do i determine which one is to be used so that I can create the relative registry entry?
I tried setting a condition for both/either of them ie ALLUSERS=0 or ALLUSERS=1 but that only results in neither of the registry entries being created.
Thanks,
Glen Harvy

Virtual directory in what?
|
|

Hi
Check this step by step article
How to Create Virtual directory[^]
Dont know where to start. Just Click start -> Run. Type 'inetmgr' and you will list of websites.
Check the link given above and create virtual directory.

Hi,
These step will guide u to create a Virtual Directory in Windows XP:
1. From the Start menu, click Start, Settings, Control Panel, Administrative Tools, Internet Information Services
OR
Start - Run - type inetmgr
2. In Internet Information Services, expand your computer name, expand the websites and right click websites - select - New, Virtual Directory
3. In the first screen of the Virtual Directory Creation Wizard, type an alias, or name, for the virtual directory (such as MyWebData), and then click Next. It can be the name of the folder where you have the aspx files.
4. In the second screen, click Browse. Locate the folder where you have the aspx and cs files. Click Next.
5. In the third screen, select Read and Run scripts (such as ASP). Make sure that the other check boxes are cleared. Click Finish to complete the wizard.
6. For ASP content, you may want to confirm that an application was created. To do this, right-click the new virtual directory, and then click Properties.
7. On the Virtual Directory tab, make sure that the virtual directory name is listed in the Application Name box under Application Settings. If it is not, click Create. Note that the application name does not have to match the virtual directory alias.
8. Close the Properties dialog box
You can create an almost unlimited number of virtual directories for your service, although performance may suffer if you create too many of them. For further reading, you may refer:
