I have a GridView whose AutoGenerateColumns="False". However, I don't want to statically specify the HeaderText for the columns in HTML markup. Rather I'd like to set the HeaderText to be the name of the underlying SQLDataSource column name. How can I do this?
I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.
I have a Gridview, lets call it GVDistinctDate which displays Distinct Date in one column only. For example: I got 5 rows, and 1 column where the column only display distinct dates such as 02/04/2010 | 03/04/2010 | 04/04/2010 | 05/04/2010 | 06/04/2010 where obviously this dates come from a table in the database.
Now i want to take those dates in GVDistinctDate and assign it to another gridview, lets call it GVReport, as column Header Text. For this GVReport, the first column would be StudentID where a list of studentid will be displayed, and then starting from the second column onwards, where the Header Text would be the dates from GVDistinctDate, will display a Status of absent or present according to the studentID and the corresponding date. How do it get the dates from GVDistinctDate into the column Header Text of GVReport?
AND how do it display the Present or Absent status based on the studentID in column 1 GVReport and the dates on the Header Text? Below are the codes of how i got the distinct date into GVDistinctDate
The code below is for GVReport and the comments are where i tried to put in the dates into the column header text.
There is a problem here: GVReport.Columns(k).HeaderText = headerText Error:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have a grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX
In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.
I have a gridview with an edit command button. When I press the edit button, it makes all the columns of the selected row editable. But I want it to make only few columns of the selected row to be editable...how can I do that?
I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID File Name Log Upload Date Uploaded By Download Delete 3
i know how to find the index of selected row in asp gridview , but i need to find the index of selected column in asp gridview ?for ex:i have i gridview contains columns with header ( the header is the primary key i looking for ) , this grid contain linkbutton , i want to get the column header name on click on linkbutton ?
I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.
In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.
Even having the collapse and expand option for each groups is required.
I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.
Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates: grdvMyTest.HeaderRow.Cells.Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
