Forms Data Controls :: Linq To Sql And Gridview Control?
Aug 11, 2010
I recently created another post (http://forums.asp.net/t/1589122.aspx) that I now realize was barking up the wrong tree... I have a better idea of of the 'ball park' my issue is really in now... in the past, I have used a sqlDataSource control to bind data to a gridview, in which case paging and bidirectional sorting are truly an 'automatic' feature. However, now I am using linq to sql directly to bind data to a gridview, so not only do I need to handle my own paging and sorting, how youdo it is different.... I think I need to actually re-run the linq to sql query on every sort or page action..? well, not sure, that's why I'm posting this. What do I need to do?I'm also wondering if what I will need to do to implement paging/sorting is complex enough that I mind as well be looking into how to implement 'efficient' paging and sorting, as in only actually returning the subset of records that should be displayed?I need some guidance, specifically on paging and bidirectional sorting a gridview control, when the data is being retrieved from linq to sql queries... no datasourceControl
Instead of usng FormView with SQLDataSource control, I like to use it with LINQ-to-SQL. For example, can I write my own LINQ to SQL for Edit and Update? Will FormView control work in this way?
I have Gridview control which bind data from LINQ datacontext object which use store procedure. sort the gridview using LINQ datacontext object which use store procedure.
I am trying to figure out how to bind my link results to a datasource so it can manage/update/edit/insert/delete without me having to do manual coding for all of it. Is this possible?What am I doing?I have used the LINQ to Active Directory to access our AD accounts. I need to make this a webpage frontend of basic search and managing functionality. I have it searching now and adding the results to a gridview but edit is not working now. I was looking online and I saw something about being able to bind linq results to a datasource and then using the datasource to manage all the information for me. Resources I am using:
I use linq query as below and bind it to listview. I have 2 label control (name,remain).I want to check in code behind if p.count<200 then remain ="Sample text1"if price <300 then "sample text2".I know that I could do it before linq in gridview RowDataBound event
Dim prod= From p In db.products _ Select New With {p.name p.category, p.count} postlist.DataSource = prod postlist.DataBind()
I've got a gridview that will allow clients to edit options they've already entered on another page. The gridview has three radio buttons in it each with a value of 1,2,3. The option value in the dataset is 1,2 or 3 respectively. I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.
I am new to this forum as well as Visual Studio and asp.
I am connecting to an access db using Visual Studio Express 2010.
I have a dropdownlistbox that pulls names from a database. When I select a name Gridview1 gets populated. Now I want to populate Gridview2 with more data when I click 'Select' link in Gridview1 but it's not working.
I am passing name (string) and number (number) fields to the gridview2 based on the gridview1.selectedvalue property and am seeing:
In my scenerio, i've a dropdownlistbox by which i want to filter, a textbox for the text to filter and two textbox for specifying from and to date.
A gridview control for displaying the filtered data and a sqldatasource control and a commandbutton called search.
The following code is used to filter the data in database and it works properly. But when i click on edit in gridview, the gridview displays no records and again when i click on search button the data is displayed on the gridview displayed with the selected row in editmode.
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
I have managed to place a dropdown control iniside a gridview control. The dropdown does indeed populate in each row... Question: How is it possible for the system to correctly select the text in the dropdown based on the value of the field which is driven from the database? Is it to do with the selectedvalue?
i have a gridview control i added checkbox contrl dynamically but i am not getiing the reference of checkbox in button clilck event here is my code Gridvew
The width of the gridview control got increased in the browser, Because of that I got Horizontal Scroll. I don't want to get Horizontal scroll in the browser.
I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn 1 1111 2222 3333 Yes / No (selected Yes) 2 2222 3333 4444 Yes / No
