DataSource Controls :: Filling A Gridview With A Multiple SQL?
Aug 3, 2010
i have a table containing multiple agents , another three containing events ( three types of events , each category in a diffrernt table) organised by each agents! , i have to figure out how to fill a grid view that regroups a summary of the activity of every agent ! for example :
that means that the agent 1 have organised 3 EVENT1 0 EVENT2 and 2 EVENT3 ....
i have used the count(*) clause to fgure out the number of rows in table events referencing to each agent (group by) but it seems that value 0 is not returned by the clause , so i'm having a problem getting the exact values!
secondal , i have putted two calendar that will fix the beginnig and the end of the summary , but it seems that the end day is not included : it says 18/01/2010 00:00:00 and i have some events planned in 18/10/2010 14:10:00 so they are not counted !
My original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say
String[,] ary1=new String[2,10];
I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.
In a webform I have two textbox (txtDNI and txtAPE), 2 buttons (b1 and b2), 1 gridview (myGV) and 2 functions (dt1 and dt2) that return a DataTable txtDNI will be a parameter for dt1 function and txtAPE will be a parameter for dt2 function
When I press b1 myGV will be fill with the dt1 function's datatable and when I press b2 myGV will be fill with the dt2 function's datatable myGV allows paging=true and when I press the next index (2 or other) It appears a PageIndexChanging error. So the pagination isn't automatic and I have to code the PageIndexChanging event When I use a ObjectDataSource and I connect it with myGV the PageIndexChanging error dessapears and the pagination is automatic The problem is the ODS only have a one selectfunction (dt1 or dt2) but not both and the configuration is on design time
The same happen with the PageIndexChanging event where I fill myGV again (with dt1 or dt2) and set the new index (myGV.PageIndex = e.NewPageIndex) and What is the problem?? ... the problem is, for example, when the user erase txtDNI and change index of pagination ... the PageIndexChanging event is fired and call the dt1 function but the txtDNI(parameter) is empty and occurs an error, the function returns an empty datatable and myGV is empty too for avoid this I create viewstates variables for each function, so I have a 2 viewstates and fill them when the user press b1 or b2 When user press the pagination, the PageIndexChanging event catch the viewstate variable and convert it into a datatable and the problem of the automatic pagination is controled The problem is I don't have 1GV in the webForm I have 5GV in some pages... and I try to avoid...
1. all the code in the PageIndexChanging events of each GV in the webform. 2. use the viewstate variables
I don't want to databind a gridview, I want to be able to add rows myself within c# code. I can see there is a GridViewRow object and wondered if I can use this to add/remove rows as required?
What I'm trying to do is fill the buttons name programatically. So far I will get X and Y values and i need to change the text of that button at that position.
I know it's possible to do x0_y3.text = xxxx for each position but this will take years, i'm looking for a solution using a loop or some other technique to easily replace the text values. and the buttons are under an updatepanel.
ex : GIVEN : xx=2 yy=2
ex. WHERE IT IS "x" & xx and "y" & yy REPLACE TEXT WITH "hello"
I tried something like this, but it doesn't work with the updatepanel for some reason, but it works fine if i use a simple panel
Code: For Each c As Button In UpdatePanel1.Controls.OfType(Of Button)() MsgBox(c.ID) c.BackColor = Drawing.Color.Yellow Next
I need a GridView with 6 columns, one of which ("ItemID") is a HyperLink who's URL and text is determined from the C# code as I will get that data from an SQL database
INITIALLY, what I wanted to do, which would have been easy as pie, is:
[Code]....
HOWEVER, this does not work because every row in the Item ID column is filled with "System.Web.UI.WebControls.HyperLink". Apparently, this is what the HyperLink's toString() method returns. Apparently, you can't just throw a HyperLink into a DataRow and call it a day. I need to know how to make this ItemID column into such a HyperLink. It doesn't necessarily HAVE to be a HyperLink control, it just has to be able to call my javascript function on the aspx page, "popUp(URL)"
To give you a visualization of what I'm trying to achieve: this is a change log for an inventory system. The ItemID column indicates what item was altered. However, simply just having a number there doesn't say much, so I'm trying to create a link with the text, for example, "42 (motherboard x)". In other words reader["ItemID"] + " (" + reader["Description"] + ")", and that link will run a javascript function I have called popUp(URL) which takes a URL and opens it in a new window of specific size and location, to view that item's details.
I've tried various other methods such as disabling AutoGenerateColumns and manually create a HyperLinkField, but to no avail, because I couldn't get it to run my javascript function that way.
I'm using asp.NET MVC, and am looking at the JQuery autocomplete plugin for what I want to do. I need some extra functionality that I don't think it provides.
I have a page with two text fields, First and Last name. Ideally, when someone begins typing into either, I would like autocomplete to display both the first and last name of all matches. If one of these matches were selected, I would like only the appropriate (first/last) name to go into the current field, while the other field is also filled in with the appropriate name.
So the problems here are that A) I would like the suggestion text to be different from the value that would be filled into the current field, and B) I would like to update multiple fields from a single autocomplete. Does this make sense? It seems to be difficult to find information on this situation on the net.
I have Gridview on my webapplication and it is getting filled with multiple rows . When clicked on Save I want to Insert all rows without calling multiple database hits.
Is there any way I can insert all rows by single db hit?
I am trying to write an app that has one gridview, but I change the select on my sql data source to show different information on the same grid. For example I start showing units, but when price is selected I reassign my select command from Select sales.[sales1] to Select (sales.[price] * sales.[sales1]) as sales1.
However, this is causing a problem that I cannot understand with the built-in edit functionality of gridview. Whenever I click on edit, all the data in my gridview reverts back to the original select and displays only units. Am I missing something? When I change my select command the only things I am changing are my gridview.datakeynames, sqlsource.selectcommand, and sqlsource.updatecommand. What do I need to add to make my gridview edit using the current selectcommand?
I have a checkbox column in a Gridview that I would like to use to insert the value of one cell in the row into an access database. There will be a maximun of five cells allowed to be selected so there can be one value written to one field in the database up to the maximum of the five fields. The access database has five columns: Selection1 ,Selection2, Selection3 ,Selection4 and Selection5
When the checkbox is checked, the value of one cell (PliD) should be written to each field in the database. Ie: checkbox in row 1 should write PliD value to Selection1, checkbox in row 2 should write PliD value to Selection2, checkbox in row 3 should write PliD value to Selection3 and on depending on which checkbox has been checked. I am not sure how to get the value of the checkbox and write it into the corresponding fields in the database.
So far i've populated my grid view with my roomID. however using data reader I don't seem to be able to get more than one column to auto generate even though i'm now looking for three values : SELECT tt_roomEquip.roomID, tt_room.roomCapacity, tt_equip.equipTitle is my select bit of the sql, though it's only putting roomID into my grid view.
I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.
I am trying to design my logic to do this but I want to create a dataSet which will have records from several databases, The records all have the same layout.
I am reagin the connection string paths from a table in a database.
I am asking for your help in trying figure out my logic.
Should I use the connectionString builder in conjunction with a loop to Connect, read a record into a dataset Until therer are no more records to be read from my databse table with the database name/paths tables ?
Here is my beginning code which deals with one database:
Would it be better to have a sp return multiple result sets and use NextResult() or have subsequent call to dr.execute.... () and hadle one result at a time?
To me using nextResult() on a multiresult datareader would be cleaner and easier - but it does not seem to be very "atomized". I guess I am wondering can the cost of executing multiple commands be neglected? Seems like executing multiple commands and receiving a single result set would also be easier to read/test/understand.
I am working on some project which is in classic ASP.NET, but I need to migarate that into MVCRight Now I am having a page with one button and gridview which get fill on clicking the button. Gridview has the functionality like EDIT, DELETE, Paging, OnRowCommand Event. How should I perform this page through MVC. I know gridview can't be used in MVC, so what's the alternative of that.
I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.
I create reports sometimes with a gridview and export the data to excel. Lets say I have like multiple gridviews and I wanted to export each gridview to excel under its own spreadsheet.
So gridview1, gridview2, gridview3 are exported to excel under $heet1, $heet2, $heet3.
I know how to export multiple gridviews to 1 excel sheet but I don't know how to export them separately under their own spreadsheet.
I've been researching online, and i'm continously searching, but does anyone know how to do what i'm trying to do with the gridview and excel or is this not possible?
I want search with multiple names in Name coloumn. example I have pass the criteria to Name cloumn is 'Atul', 'Mayur', 'Suraj' this three names how to pass in a query.
i have a page having 12 gridviews which cell background color depend on another cell value.now the requirement of my project is download to these 12 gridviews in single excel file in multiple sheets like gridview 1 in sheet1 gridview2 in sheet2 likewise,,,,,,,,,,,i have seen your article on downloading multiple gridviews on same page but i want in above mention format........
I have a question in gridview, I want to combine my two or more records into a single cell with two rowsfor Example i have a ID, Name, Year Start, and Year End for Column name in database and i want call it into my gridview that the Year Start and Year End will combine to Year like:
I have a set of images which needs to be displayed horizontally on the page. When the set of images reaches the edge of the browser window, they need to continue being displayed horizontally even if it means a horizontal scroll bar is made (In fact it will almost always result in a horizontal scroll bar forming).
I have tried to find some way to get images to push of the side of the page but can find no way (using basic CSS) without defining a width on a container holding the images (eg. 8000px). This is not possible as the width is dynamic (more or less images may be displayed as they are added to the database)
So my solution in theory:
I now record the dimensions of the image in the database when it is uploaded to the server. Using a repeater, if I add together the width of each image as they are loaded then I can use this number to define the width of the container. Seems to make sense right?
The problem comes when I load the images. I am not great at using the Repeater at the best of times and once again it has got me stuck. I have used the Repeater ItemCreated in my code behind but my variable which I declare (dim i as integer = 1) appears to get reset each time.
When I tried in Repeater OnLoad it didn't seem to work either.
The scenario in question can be found here: [URL]
You can see I have responsed the variable in the top left and they are all 1, hence why I believe the variable is being reset.
I need to programmatically fill DropDownList in FormView and can't find the proper event to do it. I keep getting "'GenreList' has a SelectedValue which is invalid because it does not exist in the list of items" or "Bind, Eval can only be used in databound control" depending on the event. Sample code follows (there's no attempts to bind a DropDownList there ):
