Dependable Dropdown Lists (4 Level) With Multiple Selection www.codingforums.com

Dependable dropdown lists (4 level) 1 Level dropdown list 2 Level dropdown list 3 Level dropdown list 4 Level dropdown list Every dropdown list is depends on another dropdown list For example if I select a value from 1 dropdown list then 2 dropdown list will appear. And then I select a value from 2 dropdown list then 3 dropdown list will appear. And if I select a value from 3 dropdown list then 4 dropdown list. Multiple selection will be enable. It means every dropdown list may have hundreds of values. Thus, In this situation of multiple selection of values I analyze that, use of dropdown isn't suitable because if a dropdown value has 500 related values then these 500 values disturb the page design.

SelectedIndex_ Changed Not Getting Fired? stackoverflow.com

SelectedIndex_Changed event occurs when selection changes, and selection is changed or not is decided by comparing dropdowns current selectedIndex and its value in viewstate. When we changes dropdown's selected Item using Javascript, it does not change the viewstate's value (which is previously selectedIndex). Now if you change dropdown's selectedIndex to any new index it will work fine, but if you select the previously selectedIndex (which we reset using javascript), then postback will occur, but selectedIndex_changed function will not get fired because in viewstate of dropdown, selectedIndex is same as the Index we select after resetting it using javascript.

SQL Reporting :: Reportviewer Parameters Not Being Accepted On Initial Load forums.asp.net

I have an ASP.NET web site using a reportviewer control in local mode. The reportviewer is hidden on page load because I want the user to make dropdown list selections first and then click a "Run Report" button to view the report. The problem is the first time the "Run Report" button is clicked, it does not accept the dropdown selections. For example, if I load the .aspx page, select a StartYear of 2005 from the first dropwdown and EndYear of 2009 from the second dropdown, and click "Run Report". The report displays, but instead of using my dropdown selections, it uses the dropdown default values. Also, the dropdown selections I made are not preserved (they go back to the default values). However, if I then make new selections and click "Run Report" again, the report displays correctly and my dropdown selections are preserved as I hoped they would be the first time I ran the report. Has anyone run into this problem before? It appears everything is working correctly, it's just that initial load that is causing the problem.

Data Validation List - Country Names Are Selections But 2 Digit Codes Need To Be Result www.excelforum.com

I've written a procedure that loads a list of country selections in a dropdown (see attached/vb editor/ThisWorkbook). The problem is the valid values for this column need to be just the two digit country codes, not the country code +dash+country name. The reason the dropdown selections include both the two digit country code and the country name is because most users will not know the two digit codes. Presenting the selections in this fashion will make t much easier for the user to make the proper selection. So here is what I need: When the user makes a selection from the dropdown list, the resulting value needs to be the two digit country code only. Is there a way to incorporate this formula .... =MID(B2|1|2) ... in the vba procedure which runs after the user makes a selection? Or, is there another way to accomplish this? Example_COO.xlsm‎

C# - Can Set Dropdownlist Default Values Based On Variables stackoverflow.com

I have several pages linked together that I want to maintain drop down selections for. I've seen a number of ways to do this with session values, etc, but I want to set the default value while still having the option of selecting other values. Effectively, users will make selections on page 1 and then on page 2 they will use those same selections, but also potentially want to change their selections. My thought was that I could load the selections into a table in SQL in page 1 and then in page 2 call that table and set the values as variables. My question, then, is how I would set the default dropdown value to be a variable as opposed to a set value. I am using VisualStudio2010 with ASP Webforms using C#.

DataGridViewComboBoxCell SelectedIndexChanged Event? forums.codeguru.com

On a form I have a DataGridView. Inside this DataGridView i have several columns of which one is combobox and the others are textboxes.The combobox column is populated with values from a MySql database table using a query. So far so good. What i want next is to populate a certain textbox from that DataGridView, automatically after a value from the combobox is selected. When a value is selected from the dropdown list of the combobox, that value is used in a SQL query to find the value that will be displayed in the textbox.All the textboxes and the combobox are inside the DataGridView!)I did this using DataGridView EditingControlShowing event because a DataGridViewComboBoxCell does not have aSelectedIndexChanged event.The value is displayed correctly in the textbox, but the problem is that the value selected from the combobox disappears after the selection, and the combobox remains empty. I need the value to remain in the combobox after it was selected and after the corresponding value was inserted in the textbox!Here is the code for this: Code: Private Sub test_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load'Populating the combobox [code]....

Using A Table For Both Data Entry And Building An SQL String www.access-programmers.co.uk

I have a table that lists county names. On the data entry form only the county names are displayed. However, I have another form that is used to build a custom query based on various criteria, of which county is one. To make the table compatible with both both forms, the data source for the dropdown list for data entry is: Select * FROM county WHERE county <> "No Selection" For the SQL form the code is simply: Select * FROM county The default value of the dropdown list is "No Selection". When dropdown list for county is set to "No Selection" the program interprets it as "select all counties". Other dropdown lists provide other parameters such as the project year, nature of the project etc. Each of these other dropdown lists also have a default value of "No Selection". The SQL form thus gives me the ability to mix and match several criteria. For example, it will display all projects in a particular year for a particular county or all projects in all counties that involve the construction of a residence. My question, instead of physically having the string "No Selection" in the table itself, is there a way to embed the phrase "No Selection" in the SQL expression itself and still have it as an option on the dropdown list?
