C# - Change Column From DataGridView In Runtime?

Aug 23, 2010

I'm filling a previously created DataGridView on an ASP.NET Web Form dynamically with a DataTable, but I want to change the name of the columns that appear on that DataGridView, and I simply can't figure out what I'm doing wrong. Below is the code:

DataTable dtUsuarios = DBManager.RunSqlGetDataTable(
@"select b.UserName, c.Email, c.IsLockedOut, c.LastLoginDate,
case
when e.RoleName is not null then 1
else 0 end Admin
from dbo.aspnet_Applications a join dbo.aspnet_Users b
on a.ApplicationId = b.ApplicationId
join dbo.aspnet_Membership c
on b.ApplicationId = c.ApplicationId
and b.UserId = c.UserId
left join dbo.aspnet_UsersInRoles d
on d.UserId = b.UserId
left join dbo.aspnet_Roles e
on d.RoleId = e.RoleId
where a.ApplicationName = 'Mont Blanc Catalogo'");
dtUsuarios.Columns["UserName"].Caption = "Nome Usuário";
dtUsuarios.Columns["Email"].Caption = "E-mail";
dtUsuarios.Columns["IsLockedOut"].Caption = "Bloqueado";
dtUsuarios.Columns["LastLoginDate"].Caption = "Último Login";
dtUsuarios.Columns["Admin"].Caption = "Administrador";
DataView dvUsuarios = new DataView(dtUsuarios) { Sort = "UserName" };
gdvUsuarios.DataSource = dvUsuarios;
gdvUsuarios.DataBind();
//gdvUsuarios.Columns[0].HeaderText = "Nome Usuário";
//gdvUsuarios.Columns[1].HeaderText = "E-mail";
//gdvUsuarios.Columns[2].HeaderText = "Bloqueado";
//gdvUsuarios.Columns[3].HeaderText = "Último Login";
//gdvUsuarios.Columns[4].HeaderText = "Administrador";

Setting the values changing the caption of the DataTable doesn't work, and after the DataBind, the Columns.Count property for the DataGridView return zero columns! After executing the code, everything appears normally at my asp page, but the captions are wrong.

Web Forms :: Does Exporting DataGridView To Excel Has Limitations Of Columns Or Column Types

May 7, 2015

I am trying to export my Model to an Excel sheet. I have 31 fields out of which only 29 are exported. Among the 3 fields that I am not able to export 2 are of type Enum and one of DateTime. Their is another DateTime field also, but that is exported properly. Here are few fields of the model :

[EnumDataType(typeof(Suffix)), Display(Name = "Suffix *")]
[Required(ErrorMessage = "Suffix is Required")]
public Suffix NameSuffix { get; set; }
[EnumDataType(typeof(InquiryStatus)), Display(Name = "Status")]
[Required(ErrorMessage = "Status is Required")]

[Code] ....

Among the 4 fields above, NameSuffix, Inquiry_Status & FollowUpDate are not exported. InquiryDate is exported.

My exporting code is :

DataGrid dg = new DataGrid();
dg.DataSource = inqs.ToList<Inquiry>();
dg.DataBind();
string filename = "InquiryList_" + DateTime.Now + ".xls";
Response.ClearContent();

[Code] ....

In the ContentType, I alos tried with ""application/ms-excel";, but that makes no difference.

What can be the error for the above ?

Forms Data Controls :: DatagridView Postback / Cannot Make The Datagridview's Buttonfield Respond?

Feb 17, 2011

I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.

protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}

It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.

I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

Forms Data Controls :: Changing Image In Image Button Column In A Datagridview?

Oct 21, 2010

Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

AJAX :: ComboBox Input / Whenleave The Combobox It Adds To The Combox List?

Dec 3, 2010

I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).

I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

VS 2010 - When Selecting Default Option For Combobox 1 / Second Combobox Is Disabled

Jun 13, 2012

I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).

I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.

In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.
