2) on text box leave event ,im gettin data from db based on value enter in textbox and fill the labels in form

I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.
i have been trying to solve this issue for over a month and i tried many different things
i want my shopping cart list box to have items in it then I save all of those items in a session variable. I pull that session out on my checkboxlist page and I want it to autocheck all the items that were in my previous listbox that are now in the session
I also want to to this the other way so I can check a new item in my checkboxlist and I want it to automatically put the item in the listbox The issues I have been getting is a ListItem error or a List<Product> Error it does not work no matter what ways I try it
I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:
i need to design the asp.net vb page where there will be checkboxlist , where user can check and press submit and the values will be passed throught the SP ..
here is my Code , which only accept one parameter at a time
[Code]....
I have already design the checkboxlist , the problem only accour when i select more than one parameters i got this errore message :
There is already an open DataReader associated with this Command which must be closed first.
I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList, i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());and gives me error saying cannot implictly convert type 'void' to 'object' [URL]What am i missing, that when i load the page or even do a search it never displays the checkbox list as it shows in the tutorial?
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.
I am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side
I am trying to do this by something like:

switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.
Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem? Could I use a Repeater instead to accomplish this?
I am trying to populate a dropdown from a stored procedure that includes parameters. The parameters are programmatically defined variables. I have been working at this for hours, and scoured the internet for a tutorial. I have come up with the following solution below. However, it does not work. Its not pulling any data, and I am not even sure that the page is making it into the GetLast5Schedules_Selecting Event. There has to be a more efficient/less time consuming way to do this!
I have a page 3 datacontrols (in order, datalist->grid->listview, the selection from one feeds into the next) works perfectly locally, using dot net connector for mysql. My webhost uses ODBC, and I had to remove [ ] from the select statements in my code and put the table names. I removed the [ ] 's and my page runs, and my 1st/datalist control shows but now my "selected value" of my datalist, doesn't populate my grid control. I imagine theres another peculiarity with the way odbc handles parameters. Here is my original, for my grid:
<asp:SqlDataSource ID="recipegrid" runat="server" ConnectionString="<%$ ConnectionStrings:exoticingConnectionString %>" ProviderName="<%$ ConnectionStrings:exoticingConnectionString.ProviderName %>" SelectCommand="SELECT [Id], [Name], [Cal], [Pro], [Fat], [Carb], [Fiber], [Chol], [Sod] FROM [tblrecipes] WHERE ([filenameid] = @filenameid) ORDER BY [name]"> <SelectParameters> <asp:ControlParameter ControlID="DataList1" Name="filenameid" PropertyName="SelectedValue" Type="Int32" /> </SelectParameters> </asp:SqlDataSource>
example of changes to select that allowed my page to run again: SelectCommand="SELECT tblrecipes.Id, tblrecipes.Name, tblrecipes.Cal, tblrecipes.Pro, tblrecipes.Fat, tblrecipes.Carb, tblrecipes.Fiber, tblrecipes.Chol, tblrecipes.Sod FROM tblrecipes WHERE tblrecipes.filenameid = @filenameid ORDER BY tblrecipes.name">
BTW, I also tried removing my scriptmanager & updatepanel,, and using autopostbacks instead in my controls, jik, and nothing changed so I put it back.
Scenario : I want to add data from database to checklistbox on page_load and checked data should be stored in other table.I want to bind data to checklistbox like a gridview, i m trying but i m not able to.
I can insert a checkboxlist selected value as comma delimited string into the database. But I have hard time to reload it in formview edit mode. I added a hidden label to retrieve the comma delimited string and try to use checkboxlist databound event, but it doesn't work. I don't know what problem is in my code.
I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
I working on a dontnetnuke module, and was wondering how can I bind a selected checkboxlist item into the databse
Now I got it like this, but this if or 'one' selected item.
But the thing I want it, that every one of them has their own Value (abPermission.TabID, TabPermission.PermissionID, TabPermission.AllowAccess, TabPermission.UserID) (tabhome = 6,6,6,6) (tabsupp = 7,7,7,7)
If I select 'one' or 'multiple' they values will be inserted into the database
I am attempting to create a list of top ? results of a specified column(s) of a specified table on a specified database. Sounds tricky, huh? I am attempting to create a key creator for a raw data table. So far I have a list of all raw column names in the table displaying on a checkboxlist control. On the page there is a checkboxlist control on the left. A drop down menu in the middle and a gridview (hidden until the checkboxlist selects an item) on the far right. Once the user selects an item on the checkboxlist control and also selects an item (or leaves it as default) in the drop down menu (values consist of : 1, 2, 3, 4, 5, ect.) the gridview will appear and display the top (value in the drop down menu) results of the selected column in the checkboxlist control (would be nice to allow the user to select multiple items and have the gridview grow as more columns are selected and shrink as they are deselected). I am having trouble figuring this out. So far I have attempted to write a dynamic sql stored procedure, add parameters to the sqldatasource and change the value at runtime, and now I am reaching out to the ASP.Net community.
I want to select more than one item of CheckBoxList and then search those item from database and then select them.
I wrote this code but it can only select one item at a time.
for (int i = 0; i < CheckBoxList1.Items.Count; i++) { if (CheckBoxList1.Items[i].Selected == true) { var sql = from x in db.names where x.name1 == CheckBoxList1.Items[i].ToString() select x; GridView1.DataSource = sql.ToList(); GridView1.DataBind(); } } }
