How to Create a Dynamic CheckBoxList control inside of a Child Repeater Control(if we able to create in Parent Repeater Control Successfully)
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 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've the user creation form where a user will be created by entering username. Below that is checkboxlist for UserGroup which is binded with the dataset with the all the usergroup. Hence up on entering the username and checkbox selected(as the user can belong to multiple UserGroups).At database end, there are basically 3 tables-
Users(UserID,UserName)
UserToGroup(UserID,GroupID)
Groups(GroupID,GroupName)
So when i click create new user, the UserId along with GroupID(whichever checked) is saved into UserToGroup table.Im relative to this kind of process and hence facing setbacks. Can somebody help in end to end process. From front to DB SP.
I have a listview. Inside the EditItemTemplate of this listiview I want to show a Checkboxlist that has 5 checkboxes; S, M, L, XL, XXL. The values (checked / unchecked) of these checkboxes are dependent on a linq query. The linq query just retrieves the values from columns in a table. The columns are S, M, L, XL, XXL (same name as checkboxes for convenience) and all have datatypes bit. What I want now is to be able to databind this query result to this CheckBox list.
View 4 RepliesI need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
i am kind of new in the .net world. I would like to know how you can add a link column with an image to a datagriid.
P.S. i am using Visual studio 2005.
I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
View 7 RepliesI am trying to dynamically add a queryextender expression to the page. something like, when the user clicks a button, we need to add a OrderbyExpression. The following is the code used. It works when added in Page_Load but doesn't when added on a button click event. Upon button click the page just reloads and ignores the filter condition.
OrderByExpression obex = new OrderByExpression();
obex.DataField = "ProductName";
obex.Direction = SortDirection.Descending;
ThenBy tb = new ThenBy();
tb.DataField = "UnitsInStock";
tb.Direction = SortDirection.Ascending;
obex.ThenByExpressions.Add(tb);
this.q.Expressions.Add(obex);
where queryextender1 is the ID of the queryextender
I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.

So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.
I am adding an Image control to grid view in its Row created event.But i am not able to find it in Rowdatabound event handler.
And the image is not getting displayed also.
Now if the move the code to create the Image control dynamically from Row created to RowDatabound event then it is getting displayed.

View 2 RepliesI am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

View 1 RepliesI have a Data Repeater to which I need to add x number of images depending on their existence in the database.
I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.
The problem is that only the first image is being written to the datarepeater.
