Forms Data Controls :: Populate Multiple DropDown Lists With One Query?

Jan 17, 2011

I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.

I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.

Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?

Forms Data Controls :: Two Dropdown Lists That Populate Gridview?

Jul 22, 2010

I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.

My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.

Now for the problem.

User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.

I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.

What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?

Here is my code

Forms Data Controls :: Dropdown Lists And Select All?

Sep 25, 2010

I have a number of dropdown lists which are populated from a database. They load depending on what the previous dropdown selection was so for example if the system was car based and I had chosen Ford then the next dropdown list would populate all cars made only by Ford. What I'm wanting to do is add a select all to one of the dropdown lists. Does anyone know how this would be done?

Forms Data Controls :: Using Asp:dropdown Lists To Filter Gridview

Oct 4, 2010

I'm trying to create a page with multiple fields to be used as parameters for filtering a GridView. I'm using a combination of two asp:dropdown lists and two check boxes. When I select a value in one ddl, I want to clear the value in the other ddl. I was trying to use the event "onTextChanged" but that doesn't seem to fire off on the client side and I cannot seem to find any event for an asp:ddl or asp:checkbox or asp:radio button that fires off on the client side.

Are there events, like onClientClick for asp:button, that fire on the client side for these controls when a selected value is changed or when the user clicks on them? or do I need to use html controls instead?

Required Field Validator For Multiple Dropdown Lists In An Webpage?

Oct 25, 2010

I have an aspx page which has 18 (yes 18) dropdown lists and 18 text boxes. Each dropdown needs to be selected and each textbox needs to be filled. Dragging and dropping required field validators on these 36 controls and maintaining them is a painful task and does not seem to be the logical option as all I need is for the user to select a value from the dropdown.

Is there anyway I can loop through all these dropdown controls and textbox controls, check if they are empty and display warnings to users accordingly? Client-side validation solution or server side validation solution is fine with me.

SQL Server :: Select - Multiple Dropdown Lists To Only Include Table1 Entries

Aug 1, 2010

I am trying to get the drop down list to only include table1 entries where table3.int1 is the current selection in another drop down list (table2.id). Example:

Table1: id, string1, int
Table2: id, string1, string2, dec
Table3: id, int1 (ref table2.id), int2 (ref table1.id)

Both drop down lists are inside of a FormView object for a asp.net page. My current select command(s) are having the DropDownList for Table1 display all Table3 entries, instead of just the ones Tied to Table2 id from the other DropDownList.

Web Forms :: Populate Textbox Using SQL Database Query / Depending On A Dropdown List Selection

Apr 8, 2010

I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.

My current VB function looks like this:

Forms Data Controls :: Populate Dropdown List With Special Character

Nov 1, 2010

Using a gridView to read some data from a SQL database. The user can select a record in the gridview. On the SelectedIndexChanged property I populate this to a couple of text boxes & drop down list; txtCountry,ddlProvince,ddlCity.

I have special characters in France ( accent marks) and when I populate it to the drop down list it fails giving out the error message "SelectedValue which is invalid because it does not exist in the list of items".

Example of items that I try to populate are as follows. ( separated by commas) ÃŽLE-DE-FRANCE , PROVENCE-ALPES-CÔTE D'AZUR , RHÔNE-ALPES, DRÔME,ISÈRE ........ When I looked in the drop down lists for Province and Cities I see those Provinces there in the item list. When I debug line by line the word ÃŽLE-DE-FRANCE comes out like ÎLE-DE-FRANCE which is not there in the drop down list. Got to know the ÃŽ is typed by pressing down ALT+206 and lloks like this is what is coming in at the start of the string above.

Security :: Multiple Role Membership / How To Populate A Dropdown List With Users

Oct 13, 2010

I need to populate a dropdown list with users who match certain role criteria. For example, if I have the following roles: Manager, Employee, Supervisor I would like to populate the list with only the Manager and Employee roles. Some individuals have multiple roles and they should be excluded if they also have the Supervisor role as illustrated below:

Name: A , Role(s): Manager, Employee, Supervisor

Name: B, Role(s): Employee

Name: C, Role(s): Manager, Employee

The final list should only contain names B & C.

I can use Roles.GetUsersInRole("Employee") but I am not sure if this is efficient or not.

Forms Data Controls :: Populate Gridview In One Page With One Query With Different Status?

Jan 26, 2011

I have a gridview with column name:

Pending, Waiters, Opened

and in the rows under column there are figures like:

30, 50, 28
65, 0, 214 etc.

My program is working fine, when I am clicking 30, a new page opens and displays 30 rows, when I click 28 another page opens and displays 28 rows and so on.

In datatable there is a column named Stauts, actually Pending, Waiters,Opened are the status.

In dataset in table adapter I used thress queries one for "Pending", second for "Waiters" and third for "Opened".

To display data I created three pages with gridviews.

I used query like:

Select * from ..... Where status ='Pending'
Select * from ..... Where status ='Waiters'
Select * from ..... Where status ='Opened'

What is Required:

I want to make one query with status =@status and want to use header name in query or in vb.net coding and want to make only one page to display record.

To put my question as an idea/example I used three status but in real scenarion I have lot of status. If I have lot of status so I have to make lot of queries and have to create lot of aspx pages to display data in gridview that is not the correct logic.

Forms Data Controls :: Use A Query String Variable Created On The Fly To Populate A Child Webpage?

Feb 22, 2010

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.

[URL]

The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??

protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
{
string customerID = e.Values["customer_id"].ToString();
Response.Redirect("http://www.tradeselector.co.uk/customerTrades.aspx?customer_id="
+ customerID + "");
}

Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?

I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:

protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
{
e.Values["customer_created_date"]
= DateTime.Now;
e.Values["customer_update_date"]
= null;
DropDownList ddl_CountyInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountyInsertDDL");
DropDownList ddl_CityInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CityInsertDDL");
DropDownList ddl_CountryInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountryInsertDDL");
e.Values["customer_county_code"]
= ddl_CountyInsert.SelectedValue;
e.Values["customer_city_code"]
= ddl_CityInsert.SelectedValue;
e.Values["customer_country_code"]
= ddl_CountryInsert.SelectedValue;
