Checkbox To Select Connectionstring Or Sqldatasource?
Aug 2, 2010
I have multiple connectionString's to multiple databases in my web.conf. I do this to query multiple databases from a single query page. This query is past thru a url to another page (asp.net 2 with .vb page behind; no code in page behind presently), which contains the query info or sqldatasource. This page contains numerous sqldatasource due to querying multiple databases.
My problem arise's if one of the databases is down. This prevents me from searching the other databases (error, because no connection string).
My question is: Is there a way to create a checkbox for each connectionString or sqldatasource allowing me to select the database to search. if a database is unavailable; simply unchecking that database would allow me to search the other databases without error message.

I'm using Visual Web Developer 2010 Express. This is my first attempt at creating a .NET page. I have a Gridview on a page that displays the results of a GridQuery. This works. I have a checkbox control(cb_Filter) on the same page that if checked, should add to the where clause of the GridQuery, (where Column5 IS NULL). How do I check the state of the check box so it will run the query with or without the "filter".
I am using the stored procedure below for the select command of a SqlDataSource, and I'm trying to pass a query string parameter, but I get this error:
Procedure or function 'ActivationCampaignGetById' expects parameter '@campaignId', which was not supplied.

SELECT * FROM [vw_aspnet_MembershipUsers] WHERE ([UserId] = @UserId)
When I pass simple GUID like "3bd08871-d5d6-4f38-8c8a-29fd6077a719" as a UserId, then nothing gets selected. So what is the correct format for passing the GUID value?
I am trying to query my SQL database via sqldatasource in my VB.NET code for my webform and would like the results to be stored in a Crystal Report parameter field so that I can then pass it to my report
I have a form that searches for images in a database. I have several DropDownLists with various search criteria e.g. Genus, Photographer, State, Project.I'd like the user to be able to filter using any combination of these. For example they might pick a specific photographer and a specific genus but choose not filter by project or state.I'd like to find a good, clean, elegent way to do this.Here is an example of the code I have now, it has only two possible criteria. It works but I have a feeling there are better ways to do this....
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[code]....
However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?

I'd like to print out the select statement for a SqlDataSource to see exactly what is being issued to the database. I added an OnSelecting event and the code shown below. The problem is that it's printing the variables in the select statement rather than the values assigned to those variables. How do I print out the "resolved" output so that I can see the values being passed to the database.
I have a gridview that displays the contents of a database table, using an sqlDataSource. That part (including inserting, updating and deleting rows) works perfectly. What I am wanting to do is add a "search" function to restrict the rows returned to a user entered name. I have a textbox for the name to be searched and a "Search" button in the headertemplate as such:
[Code]....
The DataBind fails, with the error:
Could not find control 'txtSearchName' in ControlParameter 'username'.
Two ddl inside gridview. on selecting first ddl1 fill next ddl2 by passing selected value as parameter by executing the sqldatasource select command in codebehind.code:
GridViewRow gr = (GridViewRow)((DataControlFieldCell)((DropDownList)sender).Parent).Parent; //find the control in that DropDownList d1 = (DropDownList)gr.FindControl(ddl1); DropDownList d2 = (DropDownList)gr.FindControl(ddl2); SqliaDataSource.SelectParameters.Add("@name", d1.SelectedItem.Text.ToString()); dataView dv=(dataview) SqliaDataSource.select(DataSourceSelectArguments .Empty); Error: There is no source code available for the current location. and Returns null value
I would like to know if there is a way I can select a checkbox and this would add an end date to another table? I have 2 tables Staff_Tasks, this has the checkbox set up as an int, 1 or 0, and the other Jobs which has a field end_date. So when the user clicks on a checkbox it will add this end_date as today's date. The end_date is never displayed, its just stored in the database. I am not even sure if this is something that can be done as an SQL query or if it will be done in my back-end code? I am writing in C#. Does anyone have a little more information?
i am using a checkbox list in my project..using this checkbox stored 2 values in table..dat is2,3.. retrived these values from table,how to select both checkbox..
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
