I have a 2D array and i want to search that array. I thought Array.Find might help but it was helping only in 1D. I dont want to use for loop or foreach as that will take some time. So is there any other shortest method to find a value in a 2D array.

I'm using jqPlot and I need to turn this JSON which I receive from a WCF service:
[{ "x": 2, "y": 3 }, { "x": 25, "y": 34 }]
into this array or arrays:
[[2,3],[25,34]]
I have a datareader wich return several strings like:
ACTIA -ATSD-PKW-ACTIA-MultiDiag
TEXA -ATS-PKW-Texa-Prime"
MASTER-ATSV-PKW-Master-Master"
The strings are separted by the "-"
The idea is that I split the strings in to several dropdownlist, example:
Dropdownlist 1: (Actia, Texa Master)
Dropdownlist 2: (ATSD, ATS, ATSV)
Dropdownlist 3: (Actia, Texa, Master)
Dropdownlist 4: (MultiDiag, Prime, Master)
The problem is: How should I do this? I've search several hours on the internet but can't find anything about how to split strings from a datareader to several different arrays.
The code:

All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

Anyone know how to (have the code) to export a couple of string arrays to excel when clicking on a button?
for example, I have arrays:
string [] test = new string[500];
string [] test2 = new string [500];
i need to export in a linear vertical fashion such that column A1 - A500 contains test. Then B1-B500 contains test2.
Something easy like this.

View 4 RepliesApparently I am trying to do something that is a little unorthadox here. I am trying to use multiple arrays and bind them to one repeater in C#. I would think that there has to be a reasonably easy way to do this but I can not seem to find it anywhere online. This is what I have so far (that works). How do I bind multiple arrays to this one repeater though?
// Bind Array to Repeater repTest.DataSource = arrTest1; repTest.DataBind();
<form id="formTest" method="post" runat="server">
<asp:Repeater ID="repTest" runat="server"> <HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
</HeaderTemplate> <ItemTemplate> <tr height="30px">
<td width="40%"> <%# Container.DataItem %> </td> </tr>
</ItemTemplate> <FooterTemplate> </table> </FooterTemplate>
</asp:Repeater> </form>

View 2 RepliesI am creating an array of checkboxes :

for (int
i = 0; i < cnumber + 1; i++){
chkresponse[i] = new System.Web.UI.WebControls.CheckBox();
chkresponse[i].CheckedChanged +=
new EventHandler(chkresponse_CheckedChanged);
chkresponse[i].AutoPostBack =true;
}
2. thereafter adding them to a panel
Panel1.Controls.Add(chkresponse[n]);
3. then added the checkedchanged event:
public
void chkresponse_CheckedChanged(Object sender, System.EventArgs e)
{Label1.Text = "response";}
but the event is never fired. the panel is insdie an updatepanel.
what does such expression mean?

I am trying to bind a dynamic array of elements to a view model where there might be missing indexes in the html
e.g. with the view model
class FooViewModel
{
public List<BarViewModel> Bars { get; set; }
}
class BarViewModel
{
public string Something { get; set; }
}
and the html
<input type="text" name="Bars[1].Something" value="a" />
<input type="text" name="Bars[3].Something" value="b" />
<input type="text" name="Bars[6].Something" value="c" />
at the moment, bars will just be null. how could I get the model binder to ignore any missing elements? i.e. the above would bind to:
FooViewModel
{
Bars
{
BarViewModel { Something = "a" },
BarViewModel { Something = "b" },
BarViewModel { Something = "c" }
}
}
I am just wondering how you'd iterate through elements in a form input array when you get the FormCollection object on postback?
View 3 RepliesI'm very new to the whole thing and am slowly building a little app which takes a series of numbers into an array,orders them,does calculations and outputs the result.To this end I'm using arrays declared like:
string[] and the function OrderBy().
Eventually this little prog is intended to read text files containing perhaps thousands of values so I thought I should find out:
What are the size limits for such arrays?What are the size limits for OrderBy() ?
Is OrderBy() an effective sort routine for large arrays or does it get very slow?
I hope it is okay to ask these questions.I realise I could find out for myself as soon as I've got it to where it can upload and read a text file and process it...... but I'm not there yet.
I'm taking input from a user and need to stick it into an array, the problem is, I don't know ahead of time how many dimensions the array will have and I also don't know how many items the user will want to stick in each dimension.The array will have a maximum number of dimensions of 4, but an unlimited number of items per dimension.I'm trying to create an unordered html list creator, so I need to know the number of items in each level of the list, and since (As far as I know) you can't create a multi dimensional array with a dynamic size
View 7 RepliesI have several models that implement a array property using null object pattern in the following manner:
[Code]....
The problem is that any time I attempt to bind to a property of this type the DefaultModelBinder.CollectionHelpers.ReplaceCollectionImpl method wants to call ICollection<T>.Clear() and then ICollection<T>.Add() on the zero length array.
The real issue seems to be in DefaultModelBinder.BindComplexModel() method however. The method contains an explicit check for arrays and special handling to account for the fact that they don't support clear/add functionality. The problem is that the check stipulates that the array model must also be null. If it is non-null, normal ICollection<T> handling ensues which presumes support for clear and add. Can any one explain why the null check is there? It seems to me that either 1) the null check should be removed to permit replacement based binding to non-null arrays or 2) an explicit error stating that non-null arrays are not supported should be thrown.
I vote for the former. I can understand that in general, replacing an existing model with a refrence to a different model would be considered a bad thing. The calling code would not expect this in general and it could lead to hard to find bugs. However, in the case of arrays, if the calling code expects the array property to be modified at all, then I think the normal expectation would be that such modification would occur via replacement of the array.
I am using EditorFor to display values.
The code for the values to be generated are as follows:
<tr>
<td>@Html.HiddenFor(m => m.ID)@Html.CheckBoxFor(m => m.Authorized)</td>
<td>@Html.DisplayFor(m => m.ID)</td>
<td>@Html.DisplayFor(m=>m.UserName) </td>
</tr>
My aim here is upon the Checkbox is being checked, I need to post the ID value as follows:
[Code]....
However, var ID = $(this).parent().parent().find('#ID').val(); is undefined. How can I he read the ID value from the following generated HTML:
<td><input id="Employee_0__ID" name="Employee[0].ID" type="hidden" value="1100" /><input id="Employee_0__Authorized" name="Employee[0].Authorized" type="checkbox" value="true" /><input name="Employee[0].Authorized" type="hidden" value="false" /></td>
<td>user </td>
I have developed an asp.net application that I developed using visual studio express 2008.
With this application, I have 20 sales items. I can sell 10 of each item each day. Customers can order the items in advance but once an item has more than 10 orders for the day then I can not sell any more of the items for that given day. If a customer tries to order another item after 10 has already been ordered then I must tell them that no further items of that kind are available. So for each day there can be possible 200 orders total (20 items x 10 sales). Customers can order months in advance...
So, my question is what kind of storage device do I use to keep track of this kind of data? Database or application variable or other?
