Web Forms :: Passing Parameters In Dropdownlist And Sqldatasource
Jun 3, 2010
I am trying to pass the parameters dynamically thru Sqldatasource and get the results in grid view. Based on the dropdown list selection it has to show the results in grid view. When I hard code its giving correct results but when passing thru parameters i'm unable to get the results in grid view.
Output shud be something like this:
Select the value: 123
124
125.
Lets say user selects '123', the query it runs in sqldatasource is Select col1,col2,col3 from table1 where col1 LIKE '123%'
results will be 12301,12302,12303 with other columns in grid view.
When user selects 10 miles from dropdownlist DDL1 and types AAA20 in textbox1 which is of type text, on button click it has to pull all the columns from database and show results in gridview using sqldatasource store procedure. I'm stuck in server side code..how to pull the data..in store procedure I'm passing two parameters val1 and val2. val1 gets data from DDL1 and val2 gets data when user types in textbox1 and it has to validate the text...see the code below mentioned and tell me how to pass the params and get the data in gridview...
I need to pass a user selected value from a databound DropDownList into a GridView SQLDataSource select statement so the correct records will be selected. I have found lots of documentation on DropDownLists and sqldatasources but nothing that connect the two.
I am trying to pass the value of a dropdownlist to the Update section of a listview. The dropdownlist is bound to one datasource which needs to then pass its selected value to the UpdateCommand sql for another datasource. Here is my code:
I have a dynamic created drop down list - and I set the event of it to be like this:
ddlAnswer.ID = "ddlistAnswer" + QuestionID; ddlAnswer.SelectedIndexChanged += new EventHandler(ddlAnswer_SelectedIndexChanged);
Please note that drop down list is dynamic, and in selectedIndexChanged, I would like to pass the "QuestionID" to that selectedindexchanged to work on my logic. Is there a way to pass it to that method as command argument or something?
Code: protected void ddlAnswer_SelectedIndexChanged(object sender, EventArgs e) { //wanting that question id here }
I have big filter coming from database by using storedprocedure. This stored procedure contains about 12 parameters. In asp.net page I select these values and after doing that I want to pass these values to SqlDataSourec which is bound to gridview. How can I pass these values to SqlDataSource, manually in codebehind?
I am working on a form that I would like to display a dropdownlist or textbox to insert data into the same field.
Currently it is setup where the end user can use one or the other but not both. I am running into a problem getting with the insert parameters for the secondary control. In this case the textbox.
Is it possible to use and Or statment in my Insert Query? I have tried to no avail.
I have a page with a lot of pictures on it. I want the user to be able to click on the picture and either bring up a popup type of window passing it the Param name and value , or to have the picture be replaced with this object.
I have a custom ExpressionBuilder in whixh I'm trying to add a list of optional parameters. My method would be declared as follows: public static string GetResource(string expression, params object[] parameters) { }
The way I'm calling this method from an ASP.NET page is this at the moment: <ext:Button ID="btnEdit" runat="server" Text="<%$ AppResources : edit_text %>"> Does anyone know how to perform this method call, but using optional parameters?
passing parameters from a datalist to another page.
this is how my app works:
i have a database ( access) a table with the following columns: id,title,desc,photo.
another table with the following columns: (startsin, endsin,price,tId)
on the first page (tourpack.aspx) i have a datalist, when user clicks on a button that is in the templateitem of the datalist, he will be transfered to another page called (showtour.aspx). what im trying to do is passing the ID parameter from the first page (table 1) to the second page (showtour.aspx) with the id number so he can see the specific details of that "tour" that are located In the second table.
If I want to use a CheckBox control to set a parameter and pass it to another page in session, should my code behind look like this?
[Code]....
OpenYearRound is the ID attribute of the CheckBox control.Is there a smarter way to do this?What would my code behind look like for a CheckBoxList control? Something like this?
[Code]....
How would I retrieve those values from the session? Like this?
I'm creating a pseudo invoicing system. I've got a webform where users can pick such informaiton as days, companies, etc to pull the information to create the invoice for and then they click a submit button. I'm wondering what the easiest method would be to get this information. I've had success with such commands as:
but how can you pull this information through the SQLDataSource tools? When I choose to alter the "WHERE" in the sql clause to a control items in the previous page are not accessible.
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username and if gender supplied SELECT * FROM [this_table] WHERE gender = @gender and if both supplied SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City, @State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
I know how to pass parameters to Reportviewer in LocalReport mode via textboxes on the page where the user enters them and then they click refresh and everything works fine. What I cannot figure out is how to not pass parameters and make the report display everything, which should be the default.
I know I am missing something really obvious on the Report Parameters screen. Does anybody know the secret?
I am currently writing an ASP .NET (Framework 3.5) page that has a Grid View inside it.
One of the columns of this GridView contains only buttons, that if clicked should open a popup dialog.
To open the dialog I wrote the following code on the button's event handler:
[Code]....
Now when I click on any of the buttons the dialog opens just fine, however I need to pass some parameters to the dialog so that they can be displayed inside it. That's why I've encoded a Base 64 string and passed it as an argument of the popup dialog (apparently if I just used the plain string, the dialog would not open because the string contained linefeed characters).
Unfortunately I wasn't able to get the parameter (base 64 string) on the code behind of the popup dialog. How can I do this?
I have an ASP.NET 3.5 web form with a DropDownList bound to a table of company names in a database. I also have a data bound GridView which I would like to update with data from the database depending on the company name selected in the DropDownList, so that the SelectCommand for the GridView's SqlDataSource is:
SELECT Registration, Telephone, Profile FROM {CompanyName}_VehicleData
Where {CompanyName} is whatever is selected in the DropDownList. I've used the Command and Parameter Editor to create a ControlParameter pointing to the SelectedValue of the DropDownList, but I don't know how to write the SelectCommand query to concatenate the parameter to '_VehicleData'.
I have added a gridview in my aspx web page. I have added a hyperlink field, to navigate to another page from the gridview. I am getting the error as:
"There was an error rendering the control.
Index(zero based) must be greater than or equal to zero and less than the size of the argument list. "
This is the code i have used:
[Code]....
[Code]....
When i remove the hyperlink, the grid is getting displayed. I know, there is something wrong i have coded in the DataNavigateURLformatstring, but not sure what is wrong.
I want to pass the StudentID,CourseID,ChildImageID with the link as the querystring.
According to all I have read my DataNavagateUrlFields string should work but it isn't. The deal is that any one (AssocID) can have multiple AddrID's associated with it. Regardless of which I choose I only get back the first AddrID for that AssocId.
