Forms Data Controls :: Passing DropDownList Value Into SQLDataSource?
Feb 11, 2011
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.
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 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
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.
I am facing a small issue in using a DropDownList that has only two values (AND and OR) which i want to use to configure a SQL Query in a SqlDataSource. How can i use this thing by passing the value in a SqlDataSource Select Query in such a way to Bind the Result to a GridView. I want something like this -
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen @Option InvoiceNo = @invoiceno where @Namen is from a DropDownList and InvoiceNo is from a TextBox
I m having a problem in specifying this @Option parameter from a DropDownList which contains only two list items - AND and OR. On the Basis of the Selected Value from this DropDownList i want to execute query like
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen AND InvoiceNo = @invoiceno
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen OR InvoiceNo = @invoiceno
Using the Query with @Option gives me a Parsing Error. Why is that so. How can I implement this scenario.
I am trying to use a DropDownList in a DetailsView for the ItemTemplate, InsertItemTemplate, and EditItemTemplate. I must bind this DropDownList to a SQL-Server support table using a function that returns a DataTable. I am not allowed to use a SQLDataSource in my backwards IT department. So, not only do I need to load the DropDownList, I also need to make the SelectedValue equal to the current record that I am viewing, editing.
I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
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 have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:
Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).
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 table with a ID, CodeID,LibelleID field. I am using oracle connection. i want to display in a drop downlist (textfield) CodeID+LibelleID for exemple "100-SalaryBase" where CodeID=100 and LibelleID="SalaryBase" is it possible to obtain it if the user selects an element from the dropdownlist how to post both the codeID and ID to the controller
So I have a major issue and cannot find any solution online to solve it excepting one that is singlistviews. But i am also encounting some probs with listviews since i am not sure of to use it.Anyways so my major issue is that I have drop down lists that are being populated by a sqldatasource. Users are filling out a form selecting values in the drop down list which is fine, the prob exists with editing a record. I have the dataValuefield to be the Id of the data and the selected item in the dropdownlist id is being stored in a database. So I have the data in the database that is the Id of the selected item however I cant use the dropdownlist1.selectValue ='idNo' since that only works with listitems.
How can i access the dynamic rows in a dropdownlist that is being populated by a sqldatasource and set the selected item to a particular item?Any insight is greatly welcome. Even how to use listviews
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:
The DataBind fails, with the error:
Could not find control 'txtSearchName' in ControlParameter 'username'.
I have a problem I have been googling the entire day and still have no soloution. I have a detailsview with 2 dropdownlists. Fisrt one is ddlCaregory. Second is ddlSubCategory. The value is passed from the first ddl to display the SubCategory linked to ddlCategory. Both ddlCategory and ddlSubCategory are Templatefields. This is also in VB.
The Details view has a sqlDataSource (sdsApplicants), ddlCategory has a Datasource (sdsCategory) and ddlSubCategory (sdsSubCategory). ddlCategories lists the data returned from sds Categories and save any changes to sdsApplicants. I can get ddlSubCat to display the correct SubCatagory bases on ddlcategory sesection but as soon as I try bind it to sdsApplicants I get the following error
'ddlSubCategory' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
Let's say I have DropDownList ddlRooms bound to the datasource which returns list of available rooms from table tblRooms. On the other hand I have users, and their info is stored in table tblUsers. Using FormView frmUsers can be inserted, edited and updated... frmUsers is be bound to separate datasource. To each user, I would ilke to assign a room, so the value of txtUserRoom will be populated based on the selected value from ddlRooms. How can i pass the selected value of ddlRooms to txtUserRoom while keeping txtUserRoom stil bound to user datasource? Do I need two separate fileds or can i just put value of ddlRooms into datasource user?
I am developing web-app in .NET for 5 months (and enjoying it =)) and I am reading 3 books, all of them teachs at least 2 methods for acessing data: ADO.NET and SqlDataSource object.
I am used to work with ADO.NET method because I feel that even if it needs coding by hand, I can separate the SQL routines from the page and I can customize database routines better.
For now I am using DataReader mode because the application and the database is on the same server and there is only 1Gb RAM available so there is no advantage using DataSet on this moment.
Am I thinking this right? There are some things with SqlDataSource that I don't know how to do it well...
I have a routine that inserts a record on a table then gets the ID of this record using SCOPE_IDENTITY() function of SQL Server, than it uses this ID to insert another record on another table. Because I use a one-to-many relationship on multiple tables...
How can I work this situation using SqlDataSource object, is it even possible?
I have a table with articles. Every article has a column named category which value is either 1 or 2 On my landingpage the article headers are displayed as hyperlinks. All the articles with category 1 will be displayed in a repeater control on the left side of page and all the articles with category 2 will be displayed in another repeater control on right side of page. I know I can bind the repeaters to two different sqldatasource controls with different SELECT statements. But I wonder if I can do this by only using one sqldatasource control, and if this is better and proper way of doing it. If so, do I create a (datatable?) and do the sorting there?
