I am using a sqldatasource for filling one GridView and on page loading or before taking any action, there is no data (default value=null) and normally the datagrid is empty (using emptydatatext="no records found etc etc...").. Issue is I can not see the header of that grid in empty case, but only the emptydatatext!
I have tried to use some code of the references below, but no success, because I'm not using DataTable control as a DataSource, but directly filling the gridview from sqldatasource! useless references:
[URL]
P.S. I'm not usign DataTable as a DataSource, but sqldatasource (from the Data Controls), and I want to show header, when sqldatasource is null or empty ?!
I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3 endif
I would like to check if a particular value already exist in the database Gidview row. If the value already exist, tell the user that he has already entered the record and don't save. otherwise save the record. In my case I want to check the "Random number".
I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried "W:\Webs\ASPPages\cropper\uploads" DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
I have one filed that is encrypted using Rajindal algorithm and stored in MSSQL db.When I retrieve that column in gridview it's displayed in encrypted. I have the code that decrypts it but the problem is:How can I all loop throw this column values in the gridview and decrypt them all and display it in the gridview decrypted.See my code below:
i have 2 dropdownlist and gridview. Im trying to make a link after displaying the relational data in the gridview like below But how can i get the value and combine with the link
I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.
I am doing a search function where when user enters specific value (either by keying product name or product code) into textbox, data will be displayed using gridview.
However i have problems displaying it in gridview.
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I have a Transport Detaisl in DB , i want to dispay data on gridview with marquee scrolling up. Cabs are scheduled for drop every hour. So if drop is at 7pm i hav to dispaly on data of that hour from 6:30 to 7:15 later after 7:15 i have to display next hour data ie 8:00 pm drop data. I am able to get scrollin g data on gridview but how to schedlue it to scroll for such timings
In one of my application, I have around 2000 records which i am displaying in gridview with normal paging.
Now I want to change this paging facility and would like to show a "more" button at the footer(just like [URL] has). The moment user clicks it, the next set of data will be retreived. This will go on till all the records are fetched.
I have a gridview with 20 records and I have scroll bar to scroll down to view the records.I m displaying respective row data when click on the select button in grid view. The problem is whenever I select the
row, the gridview refreshes and scroll bar is going up. Ofcourse it is displaying correct data. but the gridview refreshes and scroll bar goes up.I want the selected row to be shown when I select that row.
I'm using the following code to retrieve the contents of a folder and display the info in a GridView - all good.
[Code]....
This works fine, but it returns ALL available data about the files, and I'd ideally like only a few of the columns. I'd also then like to be able to order the columns.
orders (pk as order_id and fk as custprod_id); customerProduct (pk as custprod_id and fk as prod_id); product(pk as prod_id).
Now I want to display the data in the orders table in a gridview but instead of custprod_id , I would like to display product name which is present in product table.
I have dropdown for height and age and a checkedlistbox for city this controls are populated with data from db.i have a gridview with checkcontrol column after selection of height , age and city the gridview shld get populated with the filtered data from master table and on checkbox selection the selected row shld get inserted to the table. Currently I have a select stmt...
select * from mtbl where height between drpheight.selectedvalue and drptoheight.selectedvalue and age between frmage.selectedvalue and toage.selectedvalue and city in(............) foreach (ListItem listItem in chkcity.Items) { if (listItem.Selected == true) { } }
after selecting multiple items how do i query for city ?
I'm having a bit of trouble with Paging within a GridView grid I have set up. I have added the paging but whenever I click on the next page or the last page buttons, the page refreshes and displays blank (i.e. no gridview but my regular search parameters are displayed.
I was trying to search for a solution throughout the web and came across someone that looked to have the same issue. He moved all of his queries into the Page Load method, and the paging seemed to work. I cannot do this because I have 2 different buttons: Search and My Order, both of which perform different queries based on if a date has been selected or what the search is on (Order Number, License Number, Description, Status, etc).
My paging method looks as follows:
[Code]....
From what I can tell this is an issue with no longer having the data set when making the paging call. Is there anythign that I can do?
I've been trying to bound an arraylist to a grdview for display and managed to work out the following:
[Code]....
At the point where rows are added to dt, i'm trying to get arraylist (Tweet) to be read row by row to insert each of it's fields into dt. There is no error but when run in browser, each cell of the gridview shows 'DataExtraction.Tweet'.I'm not sure where to go from here.
<body> <form id="form1" runat="server"> <div> <asp:GridView ID="press_dl" runat="server" AutoGenerateColumns="False" PageSize="1" ShowHeader="False"> <Columns><asp:TemplateField><ItemTemplate> test head test shortnews </ItemTemplate> <HeaderTemplate> </HeaderTemplate> </asp:TemplateField></Columns> </asp:GridView> </div> </form> </body> Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack() Then bind_press() ' bind_events() End If End Sub Sub bind_press() ds = Nothing ds = New DataSet Dim query As String query = "select top 1 * from tbl_press order by press_id desc" myConnection.Open() da = New OleDbDataAdapter(query, myConnection) da.Fill(ds, "Press") myConnection.Close() press_dl.DataSource = ds.Tables("Press") press_dl.DataBind() End Sub its dislpayes like this test head test shortnews test head test shortnews
Im displaying a Gridview full of data but the column "Country" is displaying the CountryID and I want it to display the Country 'Name'", same with State/Prov and a Status column I have. I've looked around at BoundField Properties and such and can't seem to find where I can configure this. Is it straight within my DataSource? Here's my code:
GridView Code
[Code]....
Here is my DataSource Code
[Code]....
Is it within the SELECT statement of the DataSource where I can need to configure using "Country" not "CountryID"or "Status" not "StatusID"?
I'm having trouble displaying the value of my textbox on the gridview. For example i have a column named Quantity Received which at the moment has no values in it then i have a textbox that would enter value for that said column .
FrameWorks.fwReplenishmentRecWi qtyrec = new FrameWorks.fwReplenishmentRecWi(); qtyrec.QtyReceived = Convert.ToInt32(txtQuantity.Text);
I have a Business object (Customers) with about 30 fields/attributesNow, I want to display list of Customers in gridview so I fetch them through my object datasourceBut gridview only uses 8 fields/attributes of an object and rest are unused or wasted Do I design sub objects containing only gridview fields ? How do I go about this problem ?
