Forms Data Controls :: Merging Two Sets Of Data Onto One Datagridview?
Mar 22, 2011
I have two SQL queries that are stored procedures that have 2 variables that my web form will be supplying through text boxes. The two queries will produce two different results. I have read a couple of different of the MSDN articles online, including this one:
[URL]
that say that the tables must be similar to be able to merge them into a single datagridview. I know that datagridviews only like one table at a time, but I was curious if anyone had found a way to merge two dissimilar tables to one datagridview or not.
I am building a web page that will be presenting users two dataset results from two stored procedures in sql but the data is not similar. Is it possible to present both datasets to users in one datagridview? I am unable to do a union of the data in SQL due to the fact that the results aren't similar and wanted to see if I could work around this issue with .net.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
just starting strongly typed data sets, I have managed to fill my data set and bind the gridview, but now I dont understand where to map the fields ? Inside the business logic layer or presentation layer.
working example to map fields with a select query and with an update .
I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?
I have a members section of a website where when they first register to become a member, they pick their top 5 sports personalities/stars. Then when they log in to the members area, I want to display members news which should show:
- at the top all new stories that have been their sportstar has been referenced to
- then all other news
(In the CMS, admins can edit a news story and they have 5 dropdowns of all the sportstars so they can for example have for a news story: Sportstar1=Tiger Woods, Sportstar2=David Beckham etc) So as a member, if I have selected David Beckham as one of my top 5s, then all news tagged with him via the CMS are displayed.
There may be a better way to approach it, but basically I am creating one DataSet, then firing off 5 SQL queries, each SQL query is like this:
[Code]....
Then in my Page Load I do this:
[Code]....
The problem is that my repeater is inl showing news for myStar1 i.e. it is nly showing the first table which will be called "News1".
So is there any easier way of doing this? Am I overcomplicating things?
I have a couple of rss feeds i want to merge into one and show on my site. I know how to display one feed but haven't found a way of displaying several feeds.
I have a C# website developed with Visual Studio 2008 with a SQL backend. I have a top Navigation menu that has seven different tabs. I have a specific right bar content for each of the seven tabs. The content for the right bar is stored in a sql database and will be accessed using data sets. I believe that I have two ways to display the information with the data set...
1. User control - Create a User Control for each data set and then drop that on to the respective pages.
2. Master Pages - Create a Master Page for each of my seven sections, adding the data set to the respective Master Page.
Is there a preffered approach to achieve my goal? I am thinking Master Pages would be the most efficient but not certain. Is there another method I should consider?
I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))
I have a datalist and now i want to give custome paging to that datalist using multiple active result set. I mean i want to show paging as
first,previous,1 2 3. . . next, last.In this I want to get only 3 pages at a time. and once i got the page, I want to put it in caching and again if user click on that page number then i dont want to get the data from cache instead of hitting the database
i am using vb.net 2008 i need to know about datagridview ......Is it to possible to add a data through vbcode in datagridview without using any datatable or dataset....
I am refreshing my DataGridView by calling using the code below:
[Code]....
However I want to use templates in the DataGridView like this:
[Code]....
So I would NOT be calling FillDataGridView() from Timer1_Tick.My question is: what do I have to add inside Timer1_Tick so that it will refresh my DataGridView (the one with the templates)
i have a table called product which contain fields of product_code and product_name....now i want to show product name in gridview field whenever i write product_code in a column.....when i write product code in gridview column then product name will be generated automatically in gridview column...how can i do this
I am pulling information from two different databases (structure is the same) and putting them into two datatables. The problem I am having is figuring how to merge the data togther in a single gridview and change cell background color for only the data in the second datatable.
I have a gridview to populate some data and I am using the following function to merge the cells, rowwise. Now I want to apply alternate colors to the grouped cells.
I have several cases in my database and for each case there is binary data. I am reading binary data for each case in a byte attray and saving it as a pdf file.I can succesfully open this pdf file.
Trying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.
I need to add 3 rows to a footer, i did a total but dont know how to add 2 more,
I have a variable credits that i would like to display on the next line and then net the 2 on the 3rd line.
I have looked at properties of the e.Row and was thinking if i could add a table?? Is there a to table method of datagridview? That way i could add the rows?
