Forms Data Controls :: Adding All The Values In Multiple Columns In A Gridview?
May 14, 2010
I'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.
I want to get the values from a cell in a gridview so can I do that without selecting a row. Its something like this I have a drop downmenu and based on the value selected in the dropdown menu I have to change the presentation of gridview without going to the database.
I want search with multiple names in Name coloumn. example I have pass the criteria to Name cloumn is 'Atul', 'Mayur', 'Suraj' this three names how to pass in a query.
I have a question in gridview, I want to combine my two or more records into a single cell with two rowsfor Example i have a ID, Name, Year Start, and Year End for Column name in database and i want call it into my gridview that the Year Start and Year End will combine to Year like:
I have a gridview that shows, for example, a baseball team's statistics. It's a standard sports stats grid - the rows show statistics for each player and the columns show the specific stat for the each player.
Easy enough so far. But what I would then like to do is style (highlight or bold) the Max or Min (the team leader) of each stat column. For example, Player A may only lead in one or two categories, so we cannot style the entire row. If Player A just leads the team in strikeouts, I just want to style the number of strikeouts he had (THAT cell only).
What's the best way to handle this? Make SQL Server do all the work and in effect, rank EVERY stat of each player, effectively doubling the number of columns (e.g. col: AB, col: ABRank). Or do I let the rowdatabound event of the gridview handle this?
If I chose the latter, I think I would get the Max of every statistical category from the datatable before binding (e.g. store them in a local variable) then on rowdatabound, if they match the value, apply the style.
I have a gridview to which I am binding a database values. My requirement is to bind the values to the gridview by sorting 3 columns as a default sorting with ASC order in one column and descending order in other two.. Can I do it in my .Net code or should I do that in Stored Procedure? If it can be done in .net code Can you tel me how it can be done.
I want to display my data from sql in a grid view. Here the problem is how do I display more than one columns under one column. For example, I have A, B, C, D, E, F columns in sql and then when displaying in Grid, I want to display as 3 columns A, B, C and under column "B" I want to Display D, E, F.
I have a gridview that is being populated by an oracle DB. The gridview have 2 columns now one shows years and the other is a checkbox column. What is happening is my years column is very long and I wanted to know if I could split the column in half. I want say from 1970-1990 in the first column. The second column will have the checkboxes for the first. I want the third column to have 1991-present day and the fourth column to have the checkboxes for the third column. Can the grid view do this or is this something I have to do in oracle and have the gridview just display it?
I have a GridView which is databound and I added two columns which are checkboxes. There is no link between the two columns. On a check box click , I need to check to see any other check boxes on the same column checked, if so, show a javascript confirmation . If click ok, need to do postback to update the database.if cancel, no change. The goal is ,I need to make sure that only one check box is checked in a check box column.
Is it possible to first add controls (ie. CheckBoxes) to a GridView with AutoGenerateColumns set to true. Then to click a single save button which loops thru the controls in the GridView, gets their values (ie. Checked/Not Checked) and then saves those values to a database?
I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?
I'm having difficulty adding a repeating header row, every x rows, to a gridview. I'm able to add the header only once with the below code. For some reason it will only add it during the last iteration through the for/next statement. I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement. I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.
Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number): Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound Dim grid As GridView = TryCast(sender, GridView) If grid IsNot Nothing Then Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal) Dim header As GridViewRow = POSTURE_RESULT.HeaderRow For i As Integer = 0 To POSTURE_RESULT.Columns.Count - 1 Dim TableCell As New TableHeaderCell() TableCell.Text = header.Cells(i).Text row.Cells.Add(TableCell) Next Dim t As Table = TryCast(grid.Controls(0), Table) If t IsNot Nothing Then For i As Integer = 0 To Gridview1.Rows.Count - 1 If IsWhole(i / 5) Then t.Rows.AddAt(i, row) End If Next End If End If End Sub
So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.
I didnt use bound field here.as it is simple grid view with auto generate columns. I want to make some columns Editable while some should not be editable
Im into a situation, where, I need to embed linkbutton to gridview to display one field (TITLE) from database. It was done as I've added it in the itemtemplate. Now my situation is bit refined; I should add a text box and another linkbutton which should be disabled on page load and when ever I click that linkbutton which is displaying (TITLE) should make the textbox and another linkbutton visible by displaying corresponding values from the database in the textbox.
Is it possible in to set up an SQL table column to have multiple values? Or would I have to put my values into a new table and link it to the original one?
I have a form with three Gridview's. ie. GridView1,GridView2,GridView3.Each gridview contains two templatefield and a boundfield.The first templatefield is a checkbox field and the second one is a labeltemplate with databinding to field "Usr_Id" and the third field is for Name.I have enabled paging for all the three girdview's and different data's are populated on form_load.how can i maintain the checkbox status while paging for all the three gridview's.ie, when i check checkboxes in two pages in gridview1 and checked three pages in gridview2 and so on,i should get the check state of all the gridview checkboxes maintained.I know to maintain the checkstate for a single gridview but when i am checking the pages in second gridview ,the checkbox values of some pages of gridview1 is lost
