Forms Data Controls :: How To Change The Column Header From A DataSet
Feb 21, 2011
The following query returns me the column name from the table in the database, and stores the column name in the grid. How can I change the column name in the grid using following code, if its possible?
DataSet p_dsInformixDataDs = new DataSet();
string cmd = "SELECT * FROM CUSTOMERS";
try
{
using (IfxDataAdapter da = new IfxDataAdapter(cmd, m_InformixDBConn))
{
da.Fill(p_dsInformixDataDs);
}
}
DataView myDataView = new DataView(m_dsInformixDataDs.Tables[0]);
if (myDataView .Count > 0)
{
GridView1.DataSource = m_dsInformixDataDs;
GridView1.DataBind();
}
I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
I have a merged column of firstname and lastname by "Select firstname + lastname from table" but when it appears in the gridview the header text of the column is "Expr1000". How can I change the header text of that merged column?, and I want to change its text into "NAME".
I have a gridview which has a column of auto generated select buttons, where a user can select a row.However, I would like to add a column header to my auto generated select buttons in order to make the gridview look complete, but I am unable to see how I can do this. Does anyone know how I can add a header text to an auto generated select button?
I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.
when i am in ItemTemplate all the column (7 column) are label so it fit to the current screen
by when i use EditItemTemplate or InsertItemTemplate the coulmn don't fit the the current screen and
i have to use the ruler in order to see more information about the cell (which is ok - because in each cell i have a dropdownlist or long textbox)
but when i drag the ruler to the right size to see more information only the cells are moved but the header coulmn stay so i see the current coulmn with worng header coulmn
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
I am using ASP.NET 2.0 and C#. I have a gridview, which has template columns. The columns have header text available. I would like to do sorting on each of the column header in the gridview the user clicks.
How to identify which column, the user has clicked?
I have a datatable in MS SQL that has FirstName and LastName. In MS SQL I created a computed field called FullName that was ((rtrim([LastName])+', ')+rtrim([FirstName])) I created a DataSet and a Business Logic Layer. In my typed DataSet I saw FullName in the listing when I created it. I am able to use FullName in my webpage. I use it to populate a dropdownlist. However, now when I make changes to the Customer Table I am getting this error message (seen below)
Question: Should I have created the field FullName in my MS SQL Table or should I have left it alone and somehow just added a column to the DataSet and placed an expression in the FullName column? The column "FullName" cannot be modified because it is either a computed column or is the result of a UNION operator. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have a gridview which is binded to a table at runtime.So when the gridview displays the header text is exactly same as table field text which I want to change ,How can I accomplish thisFor example my table field name is MembershipNumber, so my gridview header also displays the same name. What I want is I want to change the header text to Mem No instead of MembershipNumber
I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.
When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.
I don't understand why the GridView is disappearing when I click a column header.
Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?
I want if the header of a particular column contains a word "S", the header and row turns red. I used following code to make header red and it works fine. How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)Dim HeaderRow As GridViewRow = GridView1.HeaderRowFor Each c As TableCell In HeaderRow.CellsIf c.Text.EndsWith("S") Then c.BackColor = Drawing.Color.OrangeRed End If Next End Sub
