I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:
Name question answer ----------------------- Joe question1 answer1 Joe question2 answer2
[code]....
But I would like to change it, so that each question is a header, like this:
Name question1 question2 question3 ---------------------------------- Joe answer1 answer2 answer3 Jill answer1 answer2 answer3
This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:
I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.
I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
I am dynamically adding a link button to every cell in a gridview. Adding the button works however the firing of the even handler doesn't. i need the linkbutton to call a function and pass some data for processing. My code is below. I have found solutions from the site that have gotten me this far.At the moment the gridview loads the cells with buttons in blue. when you click them they go back to plain text and no function is called.
I have a Gridview that I create a dynamic footer wired up to the RowDataBound event.
However there is a 50/50 chance that 3 of the columns will have no data.
I want to be able to dynamically hide the columns with no data if possible.
I have tried doing this in the RowDatabound event by checking if the value is = 0 but that does not work because I think the event is called to early?
Is there anyway to refer to the values in the Footer row after ALL the data has been bound?
Ideally in VB
`Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then
I am stuck at a task. What I want is, I am creating a table in the database on the fly in the code behind using the below code(in VB).Now my main problem is I want to display this table which is created in step 2 of a wizard, in step 3 using a GRIDVIEW. But as we all know a GridView needs a sqldatasource for values to be displayed, however what I need for achieving this is dynamically assign a datasource to the GridView, but I am not figuring out HOW?
Dim NewTable As String Dim FullName2 As String = "Dynamic" + "_" + lblCompanyName.Text + "_" + tbCustomerFileName.Text 'Get Row Headers and map to Fields readerXML.ReadHeaders()
I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
In my form I have four text boxes (2 in each row); Textbox_FN1, Textbox_LN1 in row 1 and Textbox_FN2,Textbox_LN2 in row 2. When a button is clicked; I want to pass the row number to the following procedure which needs to read values from two text boxes and write to DatagridView. The code below writes the literal "Textbox_FN1.txt" but I need actual value from the textbox control.
I need to create a page that will display gridview based on user wants (programmatic ally).Basically I have a list of columns then the user will choose for the list. I need also to have sorting function
I have a GridView control which I am dynamically binding to a DataTable which is populated by a query built based on a set of selected options.What I am trying to do is simply handle the RowDataBound event in order to format specific rows based on the value of a database field. The code in this event handler works fine. My problem is, calling this event causes the GridView to only display the first record in the DataTable, almost as if the Gridview stops after binding to the DataTable after the first row is bound. I have attempted adding the handler dynamically, but I get the same results.I know for a fact that there is sufficient data being returned (the DataTable fills with all of the records, and the GridView shows all the records fine when not touching the RowDataBound event).
I'm adding the handler immediately after generating the query, filling the DataTable, and binding the GridView: [code]I have also determined that, when handling RowDataBound, the GridView's DATABOUND event never gets fired; it seems to stop binding right after binding the first row.
After Filling a DataTable in GridView's DataSource . A column with check box Type appears but it created as read only column and I can't enable it or make it editable... even i tried .readonly = false and still can't be edited
Does anyone know how to pass values from adynamically created gridview checkboxes to a crystal report?Is it possible? I am using asp.net, vb.net and mssql. Here's my grid minus a few boundfields:
<asp:gridview id="grid" runat="server" autogeneratecolumns="False" cellpadding="4" forecolor="#333333" gridlines="None" emptydatatext="No Products registered for this company..."> <RowStyle BackColor="#EFF3FB" />[code]............
I have an app where I need to dynamically choose an SQLDataSource for a GridView so I can use 1 of 2 stored procedures, depending on who is logged into the system. My problem is that I am using logic like this, in the button click...
If Session("SiteType") = "Type1" Then GridView1.DataSourceID = "SqlDataSource2" Else
[code]....
This happens when you click the button that reveals the panel with the gridview in it. The user then makes changes (basically adjusting a text box on one or more liens of the grid) and then clicks "save". However, the gridview no longer knows its DataSourceID once this happens, so when I try to go through the gridview's rows - there are none.
If, in the save button's click, I put the same code, it (of course) blanks out any of the data changes I made in the form. So, simply put - how do I dynamically choose the SqlDataSource, but only one time, so that the program then keeps that SqlDataSourceID associated with the gridview until the end of the cycle? Is this a ViewState thing? I don't totally understand ViewState...
do anyone know how to add a new column in gridview using vb.net syntax?the column that i want to add is not bind to any database unlike the other column in the same gridview.
i try to use GridView1.Columns.Add("Percentage")but it turn out to be error.the error said " Value of type 'String' cannot be converted to 'System.Web.UI.WebControls.DataControlField'"
in order to create my own type of columns. USERNAME to have type ComboBox NAME to be type normal like it comes from dataset But I don't know how to create a a column that is combobox and another one that is normal like it comes from dataset.

i had a dataset that return the following data CategoryDI, CategoryName, CateoryPicture im displaying these data using gridview however i want to display only CategoryName hide categoryid, and CategoryPicture im uinsg the following code but it not working
I have a datagrid and one of the columns show the size of a file.
Ex: 87 bytes 978 kb 500 Mb 766 Gb
If i get the number of bytes, calculate the correct value (in kb, Mb or Gb) to show as you can see above and add the value on the cell, it works but when i try to sort the column it does not work. It get's the wrong order.How can i format a column on a grid view so the sorting works correctly?
I want to get value from gridview column into textbox. i have DGS4 as my gridview . and i want to use query like i used bellow. i uses some code from @luc001 but it stil not working.[code]...
how to get value from gridview column into textbox. For example if I have EmailGridview with 2 columns ID, and EMAIL. And would like under gridview to show Email value also in textbox.
I was trying to do many options, but somehow could not get result.
This is nearest, I was with the
EmailTextBox.text = EmailGridView.rows(0).cells(email) But, of course it is not working.
use vb2005I got a dataset populated into a gridviewthe negative numeric values are displayed like (e.g.)10-20-300-instead of:-10-20-300can I righttoleft a column ?
I have a gridview0 in a multiview and when I click select on a row I have theGridView0_SelectedIndexChanged sub change to a different view in the multiview, which has a different gridview1 but the same datasource as gridview0. This is when it errors out and it displays the invalid column name error, with the column name being the datakeyname of the first gridview0 row that was selected
Protected Sub GridView0_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView0.SelectedIndexChanged Dim ISTag As String = GridView0.SelectedDataKey.Value.ToString
ok this generates the boxes. I have another set of pictureboxes and i was wondering how i would be able to move those pictureboxes to the pictureboxes that were generated based on the row,column, letters, direction(left,right,horizontal etc.) they pick
For i = 1 To 15 For j = 1 To 15 buttonnum = (j - 1) * 15 + i
