View 1 RepliesI would like to ask a question about hiding a drop down in my gridview. I have a gridview and I have a drop down list to control the page size of that gridview. when there is data in that gridview, it is fine for user to see the drop down list. But when there are records in the gridview, I do not want the user to see this drop down list. How can I hide it when there is no data?

View 4 RepliesI have a listview in which I have a dropdownlist that will be repeated about 8 times. In the itemdatabound event of this listview, I fill the dropdownlist of that particular row with data. I obtain this data by using a linq query. It gets me an anonymous type in return:
[Code]....
The problem with this code is that I fire a query to the database everytime the itemdataboundevent is called. What I want to do is to fire the query only once, and have it available at page scope so I can reference it in the itemdatabound event. How can I get it like that?
I didn't had any problem using datagrid to display Sql table on ASP.NET page,
but as the table grows so as the datagrid, and now the item list is too long for one page.
So I would like to break the datagrid into several pages with page numbers. ( <1,2,3,4> click the number to go to next page)
My simple datagrid code:

I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10.
I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to).

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?
I am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.
I am using two data list one at the bottom & another at the Top to display paging. On Page load, I need to access link button placed inside Data List. Actually I had got two Datalists. I can access one Datalist Link button like this:
LinkButton lnkPg=(LinkButton)dlPg.Items[0].FindControl("lnkbtnpaging");
lnkPg.Visible= false;
This is giving no error. But if I write same code for another datalist say dlPg1, it is giving error: Index was out of range. must be non-negative.
I have a many to many table in my database called PeopleLanguage
PeopleId, pk and Languags pk each go to the own table People and Language
I know make a method call with my objectdatasource GetPeopleByLanguageId
This returns the languages that the selected person speaks and has a select
query also to lanaguageTable to get LanguageName.
I now print out the results in a datalist that is binding to LanguageName.
What i want to do is show the languages in a horizontal format with a comma after each one.
At the moment if there are 3 languages it shows each one on a seperate line / if I make it horizontal
layout I still dont get a comma. Perhaps I can use a repeater?
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.
View 2 RepliesI 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 have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.

I'm using .NET version 4.

I am in need of getting the correct sysntax for being able to use paging with a datalist whose data is being generated by a SQL Datasource and a stored procedure inside the aspx(asp.net VB...Not C#) page. A Gridview or any other rigid control that does not allow full control and layout will not work so I have to use the datalist. I have the datalist working perfectly but I need to add paging. I did some searching and found a good solution. It was a C# solution, in particular the code behind syntax so I used a code converter to convert it to VB. However, as I am not an experienced coder I need help converting the portion for handling the datalist. I am fairly confident I have the buttons on the aspx page worked out. I will ask that if you se something I need to do besides the section(5) I have listed please offer suggestions. So that you can help me better I have boken the code out into sections where I'm listing the code I copied, my code and the section I need help with. I think at a minimum I will have to change the references of Repeater to Datalist.
The section I need help with is section 5 where the original autor is referencing items generated in the Repeater where he used XML. As I said I'm using a SQL Datasource with a Datalist so I truly don't understand what I need to change to get the code behind to work with my Datalist. As always I appreciate all of you guys and ladies help. And also as always I will ask to please provide the actual code to type in because telling me how to do it just won't help very much. Sorry about that.

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?
