Asp.net - Add Values In 2nd Dropdown List After Checking That Selective Index Of 1st Frop Down In .net?
Dec 26, 2011
Basically I have a form which has 2 drop downs. In the 1st drop down I am selecting City category. When the city is selected I want to update the 2nd drop down values in correspondence to 1st value choosen in 1st drop down. I have done like this,This adds the value in the 1st Drop Down:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim s As String = "connection String"
sqlconn = New SqlConnection(s)
I have a gridview with a dropdown list that was created programmatcially. I want to have access to the selected value and to that row's Id. I have the dropdownlist created in *Gridview_RowDataBound* and I am able to use the text in the cell but my addHandler is never fired. Where do I give it the Add handler. I believe I can assign it the addhandler in RowCreated but how would I be able to set up the add handler if the button is created in rowdatabound?
[Code]...
It fits best in Rowdata bound because my dropdownlist items don't duplicate but I need to be able to use the addhandler I created.
doing dropdown list selected index changed. I wan to select an item in dropdown list and display in textbox but I got more than 1 textboxes. Is the style sheet (.css) going to hard code by our own. how do I go about starting with it as I am a beginnner using visual studio.
I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:
AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)
Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
End Sub How can i get the row's Id if GridView_RowCommand is not called?
i need some help with this problem. i have seen some solutions but written in C and im not that good to convert from C to vb.net.Well i want to 'do something' when i mouse move at an item of the combobox dropdown list.like when i move the mouse over "jkl" make the button1.text = "jkl"when i move the mouse over "def" item make the button1.text = "def"
I want to retrieve value from database.........I have a sql table with (Username [Primary Key] , Friends, dob, contact ) columns; table name is MyFriends
Now Code is...... string qry = "select Friends from MyFriends where UserName='hrs'"; da = new SqlDataAdapter(qry, connection);
I've created a custom user control that has several properties. One specifies which database I want the control to access. I want to be able to present the user of the control a drop down from which he can select which database the control will interact with. How do I get the dropdown to work? I can get default values, but have yet to figure out how to get the selectable list.
I have been searching everywhere but I am unable to find a reference to what I need.I have a huge number of entries where each entry is composed of three long numbers:
a b c 1 2 40 2 1 40 1 8 12 3 9 13 8 1 12 ect.
in my algorithm I will find that I need to disregard values in column a which will then lead me to disregard values in column b. I initially thought that I may want to use three arrays and just change the disregarded value to a null value with each iteration. find function that would allow me to not have to loop through the entire array every time.This lead me to want to define the columns as lists where I could remove specific values from the list and reduce the size of the list with each iteration of the algorithm. The problem then is how do I say, listb.remove(8) and at the same time have the corresponding values for lista(1) and listc(12) removed?
I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith" If strNames.ToString.Contains("Mike Brown") Then[code]....
I have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
Is it possible to select a value of a drop down by its dynamic index that is returning from another function whereas selectindex = 2 (generated dynamically)
Suppose you have list 1 (ilist1) and list 2 (ilist2) both lists have 3 items.
At index 0 item1 which has text "-- Select --" At index 1 item2 which has text "Yes" At index 2 item3 which has text "No"
Both lists have identical items. I would like to know if it is possible to have the selection of list one be "Yes" and the selection of list two be "No" and vice versa using SelectedIndexChanged or something of the sort.
For example: ilist1 = --Select-- ilist2 = --Select--
I have a custom control. I need to add a property, say, Comparison, to the control. The property should be set at design time using a dropdown. The Dropdown will have String values like '=','>','<' etc. I tried using Enum values and working perfectly but I need to do some extra coding to convert the Enum values to the string I required. It would be great if I can get the values from the dropdown so that I can directly use the selcted value.
I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?Ideally, we want to use the selected dropdown values to determine a query.
I am making a app that reads options of a ini dim config as new iniconfigsource("patch.ini") dim test as string = config.configs("news").getstring("test") Then I made a dropdown with options
I want my script to compare the values of the dropdown with the string readed from the ini then uses it as selected value (the so called standard value) the one uc without clicking on the arrow if the none of the values match with the string value of the ini then it executes dropdown1.selectedindex = 0
How can i make a dropdown list with checkboxes ? I have a windows app ( vb.net) and the checkboxlist control is not real an option with the available space on my form.

I need to create a sample question types web form in VB.NET which allow user to the following:he user selects the control type from dropdown (TextBox, RadioButton, ListBox etc). Generate controls dynamically based on the control type on the webform.It will always show the TextBox (where user writes the question) and (generated control - TextBox, RadioButton, ListBox etc) and save those values to the database.
How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically. VBE 2010, and I'm hitting an AccessDB
I want to have a drop down menu with the values: Year 7 Year 8 Year 9 And I want to display different tables for each the values selected in the drop down menu. For example, when the "Year 7" value is selected in the drop down menu, a table is displayed for that year.
i want to create a dropdown list which depend on each other. as example. the 1st dropdown list will let the user to select the type between sector or subsector.
select type: 1) sector 2) subsector
if the user choose sector, the sector value will be appear in the dropdownlist
I would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
