I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load
i wanted to retrieve things from the data base and perform mathmatical operations on it then post it to the user, so i was told to use the bullited list and bind it to the object dataSource
how to perform such thing??

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 have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.
I have "Testdtabse" it's consists of the Table like aaa,bbb,ccc,ddd,eee etc.. I want to bind that table names in to My droipdown list box..

I have 2 page 1-index.aspx 2-Search.aspx
in index.aspx page I have Textbox =txtsearch and Button =searchbutton
in Textbox users enter text and when they click on serachbutton it goes to search.aspx page and according to txtsearch's text it bind datalist=>DDLStore that I define in search.aspx page
below is searchbutton code in index.aspx page
protected void searchbutton_click(object sender, ImageClickEventArgs e) {
Response.Redirect("search.aspx?data=" + Server.UrlEncode(txtsearch.Text));
}
And this is method that I bind datalist => DDLStore in search.aspx page
private void GetCustomersPageWiseStore(int pageIndex) {
using (SqlCommand cmd = new SqlCommand("GCPSearch", _cn)) {
string search = Server.UrlDecode(Request.QueryString["data"]);
[code]....
this querystring come from index.aspx page but I don't know how I can define something like that for search.aspx page...I mean I want if users enter text in txtsearch in index.aspx or they enter text in txtStore in search.aspx in both position it bind DDLStore..
I am attempting to bind a Repeater (but it could be a GridView or ListView) to a list of objects. The List's type is an abstract type, which has two different classes derived from it, both with different properties. Because they have different properties, I cannot just have one ItemTemplate. If I bind a control to a property of one type of class and the other type doesn't have it, it throws an error.
Here's where I'm at:
I cannot use <% if (whatever) { %> some stuff <% } else { %> some other stuff <% } %> because I cannot access the databound item to make the choice based on its type. I cannot use the <%# %> syntax, which lets me use the databound information, because you cannot code logic like if...then...else. I cannot (rather not) call a function and return a string with the code because what I want to render is complex and contains further nested databound controls. Has anyone found an ingenious way of doing if it is this type of object, display these controls, else display these other controls?
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
