Trying to add another 2nd dropdownlist to Query String... Below This Query String works Perfectly:
Query = String.Format("SELECT {0} FROM {1} WHERE NACategory = '{2}' ORDER BY {3}", PrimaryKeyColumn, TableName, DDLCategory.SelectedItem.Text, SetSorting())
I've tried to add a 2nd DDLSubCategory.SelectedItem.Text - But its throwing and error message.
Exception of type System.StackOverflowException was thrown.
Query = String.Format("SELECT {0} FROM {1} WHERE NACategory = '{2}' AND NASubCategory = '{3}' ORDER BY {4}", PrimaryKeyColumn, TableName, DDLCategory.SelectedItem.Text,
DDLSubCategory.SelectedItem.Text, SetSorting())
Can Someone take a look I'm not sure how to write (add) 2nd DropdownList (DDLSubCategory.SelectedItem.Text)
I have dropdownlist of dates and depending on the date that the user selects from list, I would like to filter records that fall between the startyear and finishyear columns in the datasource. (My the problem is that I do not know how to declare the Startyear and Endyear from the query in the code as they appear underlined - probably the BETWEEN syntax is wrong too).
yYear = DropDownList1.Text
Using connection As New SqlConnection("Data Source=CHRIS-PCSQLEXPRESS;Initial Catalog=TorGHL;Integrated Security=True")
Dim cmd As String
cmd = "SELECT BarDetails.*, MenuHeadingId AS Expr1 FROM BarDetails WHERE (MenuHeadingId = 2)" & "WHERE " & yYear & " BETWEEN " & "(" &
StartYear & ")" & " AND " & "(" & EndYear & ")"
connection.Open()
Dim dapubcb As New SqlDataAdapterDim sqlcomm
As
New SqlCommand(cmd, connection)
dapubcb.SelectCommand = sqlcomm
Dim dspubcb As New DataSet("BarDetails")
dapubcb.Fill(dspubcb, "BarDetails")
I'm trying to pass the text value of a text box as a query string value to a stored procedure. I was hoping someone could point me in the right direction. Button Code:
[Code]....
Stored Procedure:
[Code]....
The results page datalist:
[Code]....
Code Behind of results page:
[Code]....
I'm sure i've got this entirely backwards. However if I change the NULL value in the stored procedure with some string value (eg."Donkeys") it pulls all the values that contain "Donkeys" into the datalist on my results page.

I have SqlDataSource with a few parameters (code below). If I understand this code correctly if parameter is NULL I should receive all items from the query. It works fine with query editor. But when I try to use this query on my page - with DropDownList and Textbox controls as source of parameters - it doesn't work. I suspect that main reason of problem is value which these controls pass to the query. Instead of NULL this is an empty string. Is it possible to pass NULL value from DropDownList or TextBox to
the SqlDataSource?

How to set textbox value based on dropdownlist in asp.net?
Eg: DropDown Option: * Small
*Medium
If I select Small I need textbox value as 50 and For medium 100 something like this.
I have two tables :
1- Builder
2- Project
Structure of Builder Table :
ID INT PK Autogenerated
Name nvarchar(50)
Structure of Project Table :
ID INT PK Autogenerated
BuilderID INT
ProjectName nvarchar(50)
Now i have a dropdown combo which is manually binded to Builder Table , what i want is that it would disable all those builders in the dropdown to be selected which are residing in Project Table.
On my webform, i have one grid, 2 dropdownlist and one datepicker control.
When i select items from my both dropdown and date from datepicker control, i want to populate my grid based on above mention control selections.
I have a problem with binding a DropDownList. Let's assume a database five years old with many historical records. In order to enable just working with active data every datasource has a column hidden which is occasionally set by administrator in order to clean up old records. The selection looks like
1) SELECT Id, Value FROM Table WHERE Hidden = 0
The issue arises when the user opens a form with old data. As some records in DropDownListhave have already been hidden an exception is raised as the component cannot find the data for the list. For this case the following selection is valid
2) SELECT Id, Value FROM Table
it is possible to combine these two selection queries? The display value should always use query 2 while the listed values should use the query 1.
I have a dynamically generated dropdownlist, that lists e.g. Company Names. I want to be able to select a particular Company and display associated information e.g. Name, Address, City, State... etc. in text boxes adjacent to the list.
I am trying to fire the following code from the dropdownlist "OnSelectedIndexChanged" property, but cannot 1) get the code to fire upon selection, and 2) populate the text boxes...

To what extent our institution is useful for you Dropdownlist1(Good/Poor).When user select the Poor form the Dropdownlist1 in that case ONLY POPUP screen will be displayed.The POPUP Screen as follows
Textbox (In that textbox user type the reason for Poor)
Submit(Button)
When user Click the Submit (Button) the selected dropdownlist and Remarks will be displayed in the Gridview. The Gridview as follows
Dropdown Reason
0 The institution has to be improved for lot
instead of Select the Good from dropdownlist1, user wrongly select the Poor from the dropdownlist. that time POPUP screen is to displayed.(Only when user select the Poor from the Dropdownlist POUP Screen is to be displayed in that textbox type the reason and click the Submit Button). Then Gridview as follows
Dropdown Reason
0 The institution has to be improved for lot
Then user again select the Good from the Dopdownlist1 means Previously value in the Gridview.Dropdown and reason has to be deleted in the Gridview.for that how can i do using csharp.
If the drop down list event change gridview column values to be changed.
View 1 RepliesI have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:
Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.
View 10 RepliesI'm trying to filter data based on the selected value from a drop down list and the according values of a local variable within a gridview_rowdatabound event. For example, if "In Arrears" is selected, the gridview should return all rows where the account balance is less than -100. So far, when I select a value from the dropdown list, it has no effect on the gridview. Here's the code I have:
If (DropDownList1.SelectedIndex = 0) Then
e.Row.Visible = True
ElseIf ((DropDownList1.SelectedIndex = 1)
And (AccountBalance <= -100))
Then
e.Row.Visible = False
ElseIf ((DropDownList1.SelectedIndex = 2)
And (AccountBalance > 100)
And (AccountBalance < -100))
Then
e.Row.Visible = False
End
