I have a form in asp.net mvc that retrieves records from the database. this form have dropdowns. in Edit action of controller it is must to have selected the already inserted items. suppose if i am taking the User information for edit, then its City,State and country must be selected as they inserted before.
So i tried in Edit:
int CityId_ = objAM.GetCityName(User.CityId);
ViewData["Cites"] = new SelectList(City.GetAllCities(), "CityId", CityName", CityId_);
same like country and state. but though CityId_ have value but it no appear like that. It defaults from first city (same for all) why this because ?
i just gone throught this blog where i found , the assigning third parameter name should be in the object's property. but let say I have primary and Fk relationship, but columns name are different then it seems MVC strongly coupled feature fail. Why this is ?
I wish to fill a dropdown list with data from a database table.

I want the dropdown to display the Text column and return the corresponding ID.
What control do I use? What methods can I use to retrieve the data and fill the dropdown.
I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

Values in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.

View 4 RepliesI have a gridview where i have two fields. one is product and second is sub category.
I need to do 2 things.
1. I need to populate the two combos from the database. But depending what is selected in dropdown 1 this will determine what needs to be populated in drop down 2?
how can i achieve this?
I have two dropdown linked with sqldatasources.When I select item in ddl1 then on the basis of selection ddl2 is being loaded.Is there any possiblity that if I select ddl2 then ddl1 will also load on the basis of selection?
View 3 RepliesI am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
creating a dropdown similar to the time dropdown in outlook, located in the recurring event. The dropdown shows intervals of 30 minutes based on a 12 hour time format and allows the ability to put text in it.
View 1 Replieswhen i use this code to set the selected value of a dropdown from code behind i get an error
"object reference not set to an instance of an object"
[Code]....
in above code AraeDDL is dropdownlist, and AreaFromMyDraft is a String variable that is currently storing the value to set in the dropdownlist.
I'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:
Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)
I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.
Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview
[Code]....
Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns
[Code]....
The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.
If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.
I use telerik radgrid, where i add dropdown column for add and edit new grid row.When i update grid row item the dropdown value is not disply in dropdown list, but disply in dropdown first data.
View 1 RepliesI am getting this error: "Cannot have multiple Items Selected in Dropdown", when I Edit the data.
I am trying to get the selected row "DataValueField" value from a DropDown control. but every time get the very first row value. don't know why.
protected void ddCategory_SelectedIndexChanged(object sender, EventArgs e)
I am not trying to achieve anythign fancy but just trying to set default selected value for one of the dropdown that I am using. for that I am doing Items>selected= true for whatever item I want selected when i load the page. In my case, it is a month dropdows and I am selecting date 14 as selected default value out of all 30 values but somehow, out of the blue .NEt decides to show me 29 instead of 14. I am not sure if there is some another setting that is overwritting this value.
View 2 RepliesI want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
this is with ref & continuation of post [URL]
