Mar 17, 2010
Question:-
Page is a typical search page with few filters on it. When search for records based on filters, it shows result in Gridview. From grid view records, user can click on any record to see the details which takes the focus on new page. Its working fine so far.Now when user comes back from details page to search page. I am loosing selected filters values and no result in grid view.How can i display selected filters and its results in gridview when user is coming back on search page? Any example etc.?
I have controls in the forms . After submit , I am displaying crystal report. After display of Crystal report if I come back to my form again using back button my values in the forms are not retained .(i.e) Some controls having values , some not and some have different values.
How to maintain values in the form which coming back using back button?
I've got a couple pages in my web app that are used by external applications. They will link to the pages, and pass in various querystring values to allow my app to do the searching and return the results in the page. The problem is, if the user is not yet logged into the web app, they are sent to the login page, and the ReturnURL is truncated to include only the first QueryString value. I lose the rest of the values. So far I haven't figured out a solution to this. Here's a quick example:
The external application links the user to: [URL]
If the user is not logged in they are sent to the login page, and the current URL looks like this:

I have a MasterPage and a ContentPage. On the ContentPage I Similated a TabControl by using a Menu and an IFrame. When the menu item is seleceted it loads in the appropriate WebPage into the IFrame. Now... on one of the WebPages I am creating dynamic controls on Page_Load. But when I refresh or switch menu (Simulated TabControl) back and forth, then I lose my controls and values.
In web config file I have add key values specified.
In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?
I have a registration page I enter the details of the customers and redirect to another page for capturing photo and I come back to the registration page. I want to retain all the values i entered when i land on the registration page.
To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.
As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.
I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.
I am running a LINQ query which populates a list used by a DropDownList, I need to insert an "Unassigned" value to the list. The function below queries the values correctly from the db but does not insert the "Unaasinged" value to the list.

I have this ListView that has a Drop Down List.Everything works fine (I think/hope) except that the drop down list are not showing its result correctly.This is the code.

The code behind consist of the page_load and the ItemDataBound [Code]....
I'm having a problem with my Linq to XML query. I'm getting the result data I want, but it's nested so deep that there must be a better way.Here is my XML:
[Code]....
I'm trying to get a list (simple string[]) of all Item IDs where Category Names contains "Other".Here is my Linq:
[Code]....
[Code]....
Here is a snapshot of my result from Visual Studio:The results I want are there ("item100", "item400", "item500"), but buried so deeply in the results var.
I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
I'm currently working on a highly configurable Database Viewer webpart for WSS 3.0 which we are going to need for several customized sharepoint sites. but i fear it's necessary to recap the whole issue. As background information and to describe my problem as good as possible, I'll start by telling you what the webpart shall do:
Basically the webpart contains an UpdatePanel, which contains a GridView and an SqlDataSource. The select-query the Datasource uses can be set via webbrowseable properties or received from a consumer method from another webpart. Now i wanted to add a filtering feature to the webpart, so i want a dropdownlist in the headerrow for each column that should be filterable. As the select-query is completely dynamic and i don't know at design time which columns shall be filterable, i decided to add a webbrowseable property to contain an xml-formed string with filter information.
So i added the following into OnRowCreated of the gridview:
GetColumnNode() checks in the filter property, if there is a node for the current column, which contains information about the Field the DropDownList should bind to, and the query for filling in the items.
In cbx_PreRender() i check ViewState and select an item in case of a postback. In cbx_DataBound() i just add tooltips to the list items as the dropdownlist has a fixed width.
Previously, I used AutoPostback and SelectedIndexChanged of the DDL to filter the grid, but to my disappointment it was not always fired. Now i check __EVENTTARGET and __EVENTARGUMENT in OnLoad and call a function when the postback event was due to a selection change in a DDL:
[Code]....
When i have two or more filters set which return zero rows, and i change back one filter to something that should return rows, the gridview remains empty (although the pager is rendered). I have to completly refresh the page to reset the filters. When debugging, i can see in the overridden CreateChildControls of the grid, that the base method indeed returns > 0, but anyway.the gridView.RowCount remains 0 after databinding. Anyone have an idea what's going wrong here?
am a bit unsure of the best way to go about this. I have a form where data is entered, date ranges, usernames, passwords etc and when the button is pressed on the form it searches a database and returns values which match the values entered.I can't think of the most efficient way to do this, could anyone give some pointers on where to start?I thought perhaps of writing a query and then just putting in the variables which pick up the entered values and reading it all in as one big string something like:
SELECT * FROM DB WHERE ProductID = "DateTxtBox" & "NameTxtBox"
I haven't checked the syntax but this is just to give you a idea of what I am thinking.
