Forms Data Controls :: DataGrid - Extracting Results And Hiding Rows?
Jan 14, 2010
I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.
I have a nested Datagrid, Datagrid1 and Datagrid2 with access database, Where Date1 is PKey in Datagrid1 and corresponding to it entries are filled in Datagrid2 also.
It should be like:
1. Gridview2 Should not show any button/link like Edit.
2. Should hide the columns to insert new data, i.e No add button also and GridView2 add row should not be visible of Gridview2.
In all, Gridview2 should only show the data that is already inserted and user should not be able to make any changes in it and can only view it.
Here is my aspx code for Gridview2:
[Code]....
My code behind for Gridview2:
[Code]....
As you can see i have successfully hide Edit button of Gridview2 older then 3 days. Now i want to hide the Delete and all the columns to add new data in Gridview2 older then 3 days.
Working on a site where a user does a search, it takes the input from the user and then runs an SQL command to return the data in a gridview for the user to see. I also have a button where the user can see all the results from the DB (this will be taken out later but for now the DB is pretty small) This is all working fine, but the problem I am having is that when you look at the page source the gridview populates everything in tables on the page. This makes it really easy to just copy and paste and get everything from my database. How can I go about displaying the information to the user in a gridview, but hiding the table information in the html page source?
I had a datagrid and I was hiding columns. This was working fine to show just the columns I wanted.
[Code]....
And then I realised I wasn't paging the data so I ticked that on then above code no longer worked. The Count was equalling 1 with the paging ticked on. Why would that be?
I also used the classic formatting and when I sort the columns the classic formatting goes funny, how can reapply the sorting to make it look classic?
I have a datalist that is populated via and SqlDataSource. Code is VB
I am trying to extract two Values from the Item Templete and add them together. Then I want to add a new Label to the item template with the sum of the two added values.
I am able to to this using a GridView but no success with the datalist
I have a page with 2 dropdown menus and 2 datagrids.
The datagrids get populated by a database based on a dropdown menu slection.
This page links to another page which in turn links back to the original. If the user leaves the first page and then returns back I want to keep the dropdown menus and datagrids populated.
I tried doing this with session variables but can't get the datagrids to stay populated ...
I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.
I found an application that interacts with one of googles APIs that sends requests to the API and returns results to the web page. The owner of this app has made it publicly available and even though it is hosted on his server, it acts directly with the api from anyones browser. The source code in page source is available but since I dont know javascript, it is meaningless to me.
I would like to create an app that calls this web app and have it send requests to the API, and have the results parsed to a database. Would this be possible?
I have very little ASP experience and since trying to work through accessing the API itself is complicated since it involves using oAuth protocol and I am having a hard time with this with not much sample code available.
If this is possible, how can I get access to the results from this web app?
I have an asp.net 2.0 web app and one of the pages uses a grid to add/edit items before exporting the contents to excel. The items in the grid are selected based on a dropdown list--after the item in the list is selected, the grid goes and gets the items, populates a dataset and binds the dataset to the gridview. Some of my users are experiencing an issue where after deleting a random number of rows, a row not deleted will disappear or reappear. Though I have witnessed the behavior, I cannot duplicate it on my machine where the developement occurs (Win XP Pro, IIS 5.1, vwd2005 express). The windows 2003 server uses ASP.Net 3.5
Here is the code related to editing and deleting:
[Code]....
If I had to make a guess as to what was occuring, I would say that it appears at times to retain the deleted item's index after the grid is sent back to the user and tries to delete another row. But like I said, I can't duplicate the problem on my dev machine. if this might be caused by .Net 3.5 trying to run a 2.0 site?
I put in my page 1 table like grid with this style:
header of columns are select from table persons(so number of them are dynamic)
header of each row are select from table goods(so number of them are dynamic)
in table , in each cell,show the price & the date ,that this person,buy this goods
for example,in may 2008 ,Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
so this table has 2 column & 1 row
in may 2009,
Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
and jhon buy pen & suzzan buy book so this table has 4 column & 3 row
Price Date
Price Date
Price Date
Price Date
Pencil
Pen
book
then I want in each cell,I have 1 CHECKBOX that user of my program,checked each on that want. how can I design my page?
is ther any component?or I must create <TABLE> dynamically
I need to add three columns one with combo box and two text boxes.
I need to add rows to the data grid based on the collection i get which determines the number of rows. Could anyone point to right place to add a row dynamically.
So I have a dropdownlist and I'm trying to populate it with values in the database. For some reason, half of the rows has no value. It's happenning in a sequence as well, like the first row has no value, then the second row has value, then the third hasno value....
check the VB behind code for any syntax errors.Unable to add new rows of data to a database using the DataGrid control.Compilation Error message is located at http://cforedu.com:View snap shot images of each line error at http://cforedu.com/snap.pdfThe VB code behind reads (revision 1.3):
Obviously I am using the tableDnD() function to do that, but after I swapped them, I am saving the datagrid in a DataTable as it is (altered). However this doesn't happen. I need the changes to be posted back to the server. I tried to __doPostBack() after the onDrop function with no luck.
I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box
controls.Once the datagrid binds then the events in the aspx page not firing.Issue occured when the number of rows greater than 500.The number of rows less then its works fine.
I'm trying to create a web page using Visual C#.NET 2010 on a 3.5 framework that allows users to select items through a series of dropboxes which are then saved to a temporary display grid. The problem I'm having is that I wish to allow users to save multiple combinations of selections which are saved to various rows of the display table.
Below is a sample of what I'm trying to do.
C#
[Code]....
And here is the ASPX page:

The problem I'm having is whenever I try to edit the selected column all other columns are cleared. I need to have them remain while only the selected row is altered.
I'm needing to get the selected rows, based on checkboxes, to insert into a different table than that that the gridview is formed from. I've created an innerjoin datasource to try and solve this but, still having problems finding something that works. I also need it to insert based upon a button click not inside the gridview as I believe otherwise would only hamper the situation more.
What I am looking to do is have a page with 2 seperate datagrids on, I want to be able to add the selected rows from DataGrid1 into DataGrid 2 either with a button click or using drag and drop functionality (Im guessing this would require javascript and I have no experience with this language, is it difficult to learn or could I just alter code from elsewhere?). Once the row is added into DataGrid2 I would like to be able to add some information, such as Quantity and DateDue (could this be added in a pop up box when the part is added?) Also I would like fields in DataGrid1 to be based upon a search with several different options that the user specifies, i.e the ability to search based on project number, however it would return eitheer parts or assemblies depending on a check box selected. I have very limited programming knowledge but Im guessing I would be able produce a query based on the inputs, but in order for this to work wouldnt the page to postback everytime an option was changed.
I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
I am having problems with the following. On debugging I find that when strKeywords = '', reader = "System.Data.SqlClient.SqlDataReader". However, as soon as strKeywords takes the value of anything else, reader = nothing. But the stored procedure handles the arguments fine, so I am very confused!
i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.
i have a gridview of 8 columns.I need to extract the data row by row from the the first(Message) and the last(phone_no) column and to be inserted into my sql table named massMessage.I have the codes here. Apparently im able to only extract the phone_no. My message wasnt inserted.
protected void btnSave_Click(object sender, EventArgs e) { foreach (GridViewRow gvr in GridView2.Rows) //loop through GridView
