Web Forms :: Gridview Getting Out Of Sync With Source Data?

Feb 27, 2011

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.

Web Forms :: Sync Data Between Web And Local Version Of Application - Profile Provider Crashed

Jun 26, 2010

I had to restructure my database so I could synch the data between the Web and local version of my application, which I had carelessly let run amok. I finally get all the records and schema into one database but now that I've done that, my Profile system isn't working anymore. I noticed that the relationships between aspnet_Users and _Membership (and my "profile additional items table") don't exist anymore. I ran the aspnet_regsql.exe utility and registered the DB, and I'm surprised that the registration didn't re-establish the foreign key relationships, etc.

Anyway, if someone can give me pointers on how to restore these relationships or direct me to a source that explains it (i.e., what the foreign keys should be named, if there are any other aspnet_ tables that need to be linked together), I'm pretty sure this would take care of my problem. And I just noticed that nothing is in the aspnet_Profile table. Should I start all over with a new database or is this one salvageable?

Forms Data Controls :: Gridview Not Passing Parameters To SQL Data Source?

Feb 13, 2011

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:

Forms Data Controls :: Adding Row To GridView If Data Source Is Empty

Oct 12, 2010

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.

Forms Data Controls :: Paging For Gridview With IEnumberable Data Source?

Jul 7, 2010

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?

[Code]....

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
BindGrid(); //Not Good. Removing gives me an empty grid.
((GridView)sender).PageIndex = e.NewPageIndex;
((GridView)sender).DataBind();
}

Forms Data Controls :: Limit Number Of Selected Rows In Data Source For GridView?

Apr 30, 2010

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )

The question is: do I need to limit number of selected rows in data source for GridView?

When I use paging in GridView does limiting selected rows make GridView work faster?

Now I use ObjectDataSource with Linq in functions.

[Code]....

Does this make sense or I can just use LinqDataSource without thinking of selected rows?

Forms Data Controls :: How To Use Dynamic Query Filters With A Gridview Using A Stored Procedure As A Data Source

Jul 1, 2010

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:

Forms Data Controls :: Hiding Gridview Results In Page Source?

Apr 28, 2010

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?
