The Patient Scheduling system I have built extracts current inpatient data from an enterprise health system and merges it with data from a seperate database, based on a common key. This is then displayed in a gridview control for browse/update.
At any one point in time, the client list in my system should reflect the current inpatients in the enterprise system.
The problem is that if the user has not refreshed the client list in some time, there may have been a discharge in the enterprise system and the two get out of synch. When the user selects a client from the list to update, the details of an entirely different client (usually the one below), is presented in edit mode. e.g. if the user selects the 4th client in the list, the details for the 5th client are made available for update.
I have a gridview with daatsource from MembershipUserCollection. When my collection doesn't contain any records the gridview just disappears. I want to display the empty gridview indicating no records exist rather than the grid just become invisible.
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:
I'm using a GridView to output some information regarding an account, specifically account balances. Problem is, if there is no balance linked to the account, I need for the grid to simply display 0 for each column. EmptyDataText isn't sufficient as the columns still need to be listed, but just have the value 0.
After researching it seems like I will need to add a dummy row to the gridview if it is empty, but how do I do this using C# and ASP? Quick note as well, not sure if it's relevant but the grid will only ever contain one row.
i am working on a website,As i am new to coding i got a problem in it.

I have a gridview in a user control which I'm using to display a list of items. The data source is a list of objects (not using ObjectDataSource). I have paging enabled on my gridView. The trouble is that I am forced to rebind my grid in my paging method, otherwise the grid loses all it's data when a user clicks a page button. Is there a good way of binding to an enumerable list such that the values are reused on postback?
I have a drop down which gets data from database.I want to show not all entries but the very last one entered by employee. What do I have to add to the sql script to get me very last entry and hide the rest.this is my Sql data source:

Is it possible to use dynamic query filters with a gridview using a stored procedure as a data source? What I'm thinking of is a search page where there are multiple controls to enter in a search string and a radio button for the AND/OR query filters between the various controls. If not, what would be the best way to allow a user to select an AND / OR with a group of different query controls?
Here is the page I have created thus far using a view and no AND/OR option. I but I can't get it to work with my SP, also listed below:
how to bind selected values from two tables to gridview data source, that two tables are from two databases. i created a view by using these two.But error is getting with this query,that is invalid object derivdtbl_1.Expr1. how to fix this?
SELECT dbo.Station_Channel.St_id, dbo.Station_Channel.lid, dbo.Station_Channel.Edit, dbo.Station_Channel.lChannelName, dbo.Station_Channel.lShort, dbo.Station_Channel.lPosition, dbo.Station_Channel.lTransformData, dbo.Station_Channel.lUnits, dbo.Station_Channel.lDecimalPts, dbo.Station_Channel.parameter, dbo.Station_Channel.function_value, derivdtbl_1.Expr1 FROM dbo.Station_Channel CROSS JOIN (SELECT MAX(Fecha) AS Expr1 FROM MeteoStation.dbo.Datos) AS derivdtbl_1 WHERE (dbo.Station_Channel.Edit = 1)
I am wondering about the scalability of a webpage that uses a gridview connected to an SQL data source. The SQL data source queries a database once every 60 seconds to refresh the data by using a Script Manager and Timer. The SQL query is static and is not dynamically editable by the webpage viewer.
If n people have the webpage open, does that mean that the database is queried independently n times? So if 100 people have this website open on their PCs, does the database get queried 100 independent times?
If so, is there a better way to design the webpage so that the database is only queried once and then all the open webpages get updated without the added overhead cost of multiple independent queries.
I have a grid with three columns, two of which contain drop-downs, all of them getting filled from a web service result set. Now I want to allow the functionality of adding a new record in the grid by clicking an Add button present outside the gridview.
Whenever the user clicks the Add button, a new record should be created in the grid with value list filled in the drop-downs with the available options.
What is the best possible way to achieve this considering extensibility in mind.
