Return Count Of True / False In A Column Of A Sql Table In C#?
Jan 18, 2011
How to return count of true/ false in a column of a table. I have a table in sql containing 5 columns with bollean type. Now I have to return the number of trues and falses in each column and display on my frontend.
I have an application and dependant on whether you are in the administration system or on the public website I want to show different results.
Example: in the database for a news story in the administration I may set the column value 'showonsite' to false. So I would like this to show in the administration panel only and not on the live site.
My question is, because I require the same information just with the only one column change, live site to only show true values and administration to show both. What is the most effective way of achieving this without copy paste of code?
I am trying to return true or false from popup window to the parent window. Actually the parent window has a button control, which on click popup another window. The popup window holds some emailing data and a button "send". This "send" button onclick send email. Now I want to return true if the email is successfully sent otherwise false, to the parent window. Depending on returning value a label present on parent window displays a text message. But I am not able to implement it. Because it might happen that the popup window is blocked by web-browsers popup blocker or popup window is accidentally closed by user. So how can I confirm to parent window whether or not the email is successfully sent?
I have 2 linkbutton in gridview.One is visible true and one is visible false.I want to make true the other button which is visible false in rowdatabound event for some particular column that fits my criteria.
I have a datagrid control, the first column is Revno, currently presenting info in linkbutton. i want to do a condition based on another field docid, which gets true or false value from database. if true then present Revno in linkbutton otherwise show the revbnno just as a label., thatway users does'nt have ability to clickit.
<ItemTemplate> <asp:LinkButton ID="lblRevision" runat="server" CssClass="Textboxes" Text='<%# DataBinder.Eval(Container.DataItem, "RevNo")%>' CommandName="FileDownloadRecord"></asp:LinkButton> </ItemTemplate> this docid field has flag true or false. if true meaning show the revno as LinkButton, otherwise show the revno as label. GetDocdetail(DataBinder.Eval(Container.DataItem, "Docid") on the codebehind side i can use this function. Public Function GetDocdetail(ByVal DocID As boolean) As String If DocID = "true" Then Else End If End Function
I have a dropdown list inside gridview which has a object data source and I am adding the list items as true, false which stores in the database table as a bit value. Even if i am addin the values 1 and 0 to the drop down list, its throwing the below error'grdDebug' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value My code to add the dropdownlist with list items are as below
What i am trying to do is add a column onto the data that is returned to hold true or false values for each row in the returned dataset. Basically i have a table is generated from a select query. What I want to do is add a column onto the end of this and change the value depending on whether there is a match in another table in the database for a specific parameter passed via the stored procedure. What it will need to check is if a value in the left table is exists in another table for that particular row, if there is it sets the value in the newly added column for that row as true, then does the same and moves onto the next row. Resulting in the stored procedure returning the dataset with the newly added column with the true false values set for that particular row.
I've been tinkering with MVC2 for a bit now and am REALLY excited about how well it works! But one thing that has come up seems simple enough to resolve but was hoping someone here had a better idea than I have.My model has some boolean fields and when I write this: <%= Html.Encode(model => model.MyBooleanField) %> it spits out True or False as expected. What I'd like to do is replace that with 'Y' or 'N'Some initial ideas I've had: use a jquery script to spin though all the elements on the page and replace True/False with Y/N but this raises performance concerns.Another idea I had was to build an extension method off the Html class to accomplish this but was hoping someone might have a better/quicker solution?
i am using autoeventwireup="true" .i know this means it automatically combined page events of page life cycle.but when i set it to false form is running well and i dont need to write any code.so what is the diffrence what is set it true or false

I have a gridview and in this grid i allow paging with page size 10.Now I want to find the total number of records on every page index.For example on page index 1 I have 10 records and on page index 2 I have 4 record so how do I count the number of record I just mentioned above?
I have an ImageButton that is by default set to Visible=False. On PreRender when it is toggled to Visible = True, it stays False. And by stays False, I mean the property stays False, not that you just can't see it on the form. I have stepped through this many times setting the visibility to true serveral different ways and everything fails. It just won't change the property value to True. I even created a new button to see if it was just a weird VS Bug. I am at a stand still.

In the postback option class, the autopostback property is not functioning (for true or false) to forcibly set the the post back event on web page load as defined at the MSDN Url http://msdn.microsoft.com/en-us/library/system.web.ui.postbackoptions.aspx
In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?
I have been trying to get this working for almost a week now but I can't, and now my brain hurts :(, and google can't seem to help either.I have a grid view that is bringing data back from an SQL select query. It brings back things like the 'Ref Number' 'Price value' and 7 different columns of checkboxs, checked or un-checked depending on what was entered. All this works fine and displays correctly. I have added a footer to the grid view to show the totals. I have put in the VB code below to count and show the total number of rows fetched, and a sum of the returned prices, again this bit works fine. (not using pages, it's just 1 big long list)
What I can't seem to work out is how to put in cell 6 of the footer, a total count of the number of checkboxs that are checked.I have tried things like e.Row.Cells(6).Text = gridview1.columns(6).count = "True"
and various other attemps, but all give errors.using VWD on .net 3.5 with an SQL 2005 database on win 2003 server with SP2.
