Forms Data Controls :: Displaying Session Strings In Gridview?
May 17, 2010
I have been trying to do this all day but nothing seems to work. SOMEONE please enlighten me !!! I am adding products to a string and displaying them in another page. All is good .... up till here.
Now I have a problem when saving these strings (ie: the added products) into gridview. I tried using objectdatasource but I'm getting confused. Anyone done this before ? Basically when the products are in gridview I want the user to press 'purchase items' button, and the items are written to the database.
In my website, there is a page called "SMS Log"It contains a GridView, in which there are 5 columns:
1) SMS sent time 2) SMS Text 3) Recipients 4) status 5) Button (view detail) since, "SMS Text" is large and "Recipients" are more than 1.
So Gridview looks very conjusted, also it does not look good.Is there any other control I can use other than Gridview to show above 5 columns in a well organized way.
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'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 ?
As of today my gridview is no longer showing when I run it in my browser. I have made changes to the database recently but the code behind and aspx file remains the same. No errors are coming up. Just the gridview is now blank and it was working perfectly shortly before.
On one of my pages I display a Gridview. This contains a list of questions generated by a SQLDataSource, with a dropdownlist on each row containing the answers for that question. The answer values can be different depending on the question, so I populate them in the RowDataBound event for the gridview, using question information.
As the list of questions is longer than the page I have placed the gridview within a Div which allows me to use scrollbars to navigate the gridview. I also use some methods to preserve the location of the last question answered - so that on answering a question, the gridview does not reset to show the first part of the gridview.
This works fine for IE7, which is what I have been using for the development, and which part of my customer base uses. However, the other part of my customer base uses IE6, which causes a problem.
When an IE6 user attempts to answer some questions, they run into issues. Should they scroll down the gridview, when they select a value from a dropdownlist (Effectively, when they answer a question), there is a postback and all of the visible (i.e. onscreen) dropdownlists appear to be cleared. However, on mousing over any of the dropdownlists, their value is then shown. On using either the scrollbar, or on using the mousewheel to scroll the gridview, all the dropdownlists are 'refreshed' and their values are shown.
At no point does the application appear to lose the data, it is just not showing it until there is a mouseover or the gridview is refreshed. Another odd aspect of this is that this does not apply to the first 5 rows of the Gridview. Any of these can be altered without there being this display issue. Should the gridview be scrolled enough to show some of the first 5 rows and some subsequent rows, only the subsequent rows will have this display issue.
I have tried various things to correct this - originally I called my retrievescrollposition method on the SelectedIndexChanged event of the dropdownlist, but have since moved it to Page_Load as the Else branch of if (!IsPostBack). I tried rebinding the DropDownlist in the SelectedIndexChanged event, but this only helped with the Question I was answering - the display of any other onscreen questions was still affected.
Its related to datatable in gridview store in session and then session retrive and store to database. basically i am using gridview here creating new row for button click and these row adding untill user's last entry then submit all these entry to database. so i want to use session variable to store this data temporarily and after final entry user click on submit button and all data shold be save in db.
I have a GridView which works perfect when it is not empty. Now when the source is empty I want to show an empty GridView and to be able to insert rows inside.
I have this code for the page_load event:
[Code]....
but I got the following error:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
and I have tried most solution and still I cant get the right results...I need a simple workable solution. I would like to display the header of a gridivew when it is empty
I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.
I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.
If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.
Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.
I want to display a GridView using the the selected DataValueField from the DropdownList.
I've set the Selectparameters for the GridView DataSource.
Here is my question: on clicking "BtnSelect" - How do I assign this parameter (@Id) to selected value (DataValueField) from the DropDownList and re-display the grid view accordingly?
I am building a SortedList object for use as the DataSource of a GridView control. The key-value pairs are being built manually with the "key" fields being inserted in already sorted order. The "key" column is invisible with the "value" column the single displayed data item. I set the DataSource property of the gridview to the sortedlist and call the Bind method. The gridview then displays the data in random fashion!
but it is not displaying anything, however aspx page is working fine, it is showing a field but no image and it is blank, same is the case with IMG1 column as well
I have a list of image names stored in a database, along with the id of the property they are associated with. I'd like to be able to display all of the images in a gridview and then allow the user to select the required image.
The problem I'm having is that the gridview is not displaying. I'm pretty sure it's something basic that I've missed, but can't for the life of me see what it is!
I would like a gridview (using entitydatasource) to display the search results based on values provided in textbox txtSearch and dropdownlist ddlsearch. My search controls are as follows:
[Code]....
My entitydatasource is:
[Code]....
My gridview is written as:
[Code]....
Codebehind file contains:
[Code]....
I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.
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
