Data Controls :: Populate DropDownList Using Multidimensional Array?
Jul 17, 2015
How can i read multiple column values into an array list? I am trying to read a list of category names and category ids from database into an array list; i am then binding these values into drop-down list. With my current code, i am able to do with one column only but would like to pull both cat_name and cat_id so how can i do that?
aspx
<asp:DropDownList ID="DropDownList1" runat="server" DataTextField="ct_name" DataValueField="ct_id" AppendDataBoundItems="true">
<asp:ListItem Value="-1">Select</asp:ListItem>
</asp:DropDownList>
code behind
private ArrayList GetDummyData()

I'm trying to add form data from an asp.net wizard into a session array object. The object should store the question number and question answer selected by the user for each question. I'm trying to use a multidimensional array to store the question number and the associated answer. I would also be open to using a hashtable or dictionary solution.This is the code I've got so far:
string[,] strQandA = new string[10, 2] {{"1", Q1.SelectedValue}, {"2", Q2.SelectedValue}, {"3", Q3.SelectedValue}, {"4", Q4.SelectedValue}, {"5", Q5.SelectedValue}, {"6", Q6.SelectedValue}, {"7", Q7.SelectedValue}, {"8",

I need to add values in an multidimensional array whitin an while loop. But I don't know how.
public Array getDailyAvgRatingByCompanyId(int companyId, int periodStart = 0, int periodEnd = 0)

int[,] arr = { { }, { } };
string queryString = "SELECT num_ratings_day, rating_gem, daymonthyear FROM company_rating_daily_avg WHERE company_id = " + companyId + " ORDER BY daymonthyear ASC";
SqlDataReader myDataReader = Database.sqlDataReader(queryString);
if (myDataReader.HasRows)

while (myDataReader.Read())

//Something like arr[0].Push(myDataReader['num_ratings_day']
}
}

I have a datareader that i loop through comparing the values of the reader to the ones i got in an (from the start, empty) array, as i do this i want to put either a new post in the array or update an existing post depending on if i found a corresponding value or not. The datareader and array both contains name and value.
First i tried to declare a regular multidimensional array, but they are fixed size so that seemed like a bad idea, next thing i tried was creating an arraylist but they seemed to lack support for multidimension. I'm a bit lost on what to use.

I have a dropdownlist in datalist. I use arraylist to bind the datalist. In arraylist it is "DataNew" Class which has the property of DataTable "dt_city". Now I bind the DataTable to dropdownlist
Line73: <tr>
Line 74: <td style="width: 100px; height: 24px">
Line 75: <asp:DropDownList ID="DropDownList1" runat="server"
Line 76: SelectedValue='<%# DataBinder.Eval(((DataNew)Container.DataItem).dt_city,"city") %>'>
Line 77: </asp:DropDownList></td>
But I got the error of:
Server Error in '/AFIRS' Application.
DataBinding: 'System.Data.DataTable' does not contain a property with the name 'city'.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: DataBinding: 'System.Data.DataTable' does not contain a property with the name 'city'.

I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.

When someone selects one of the search criteria, I want the other dropdownlist boxes to re-populate with only the information from the current search and take out all other information if that makes sense. This search functionality works except it the dropdownlist boxes stay populated with all information originally loaded from the database. Here is my code:

I would like to bind a multi domensional arry to a data control (at the moment any data control will do - I just want to present the data).
suppose I have the following array:
string[,] strArr = new string[5,3];
strArr[0,0] = "0,0";
strArr[0, 1] = "0,1";
strArr[0, 2] = "0,2";
strArr[1, 0] = "1,0";
strArr[1, 1] = "1,1";
strArr[1, 2] = "1,2";
strArr[2, 0] = "2,0";
strArr[2, 1] = "2,1";
strArr[2, 2] = "2,2";
strArr[3, 0] = "3,0";
strArr[3, 1] = "3,1";
strArr[3, 2] = "3,2";
strArr[4, 0] = "4,0";
strArr[4, 1] = "4,1";
strArr[4, 2] = "4,2";
can you provide an example of how to dind this array to any of the standard data controls?

I am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.

Then I want the ddl's selected value be set from the recordset intended for the formview. I think it's just a timeing issue s I would like your help. Thanks, - EJM.

I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.
How can I fill those DropDownLists?
