Forms Data Controls :: Cannot Run Update Query Through GridView
Mar 5, 2011
I'm just trying to run a simple updatepanel based on the pbs database, and I cant seem to get the Row_Updating function right. Here is my code:
[Code]....
and here is my C# code:
[Code]....
The textboxes appear just fine when I click Edit, but when I change some text and hit "Update" nothing happens. How can I be sure that the UPDATE query did anything? How can I output the text of that query?
I tried researching on this topic, but I could not find enough information. I could find a lot of posts which suiggest how to "update the gridview with buttons outside the gridview", but I could not find the one suiting to my requirements. I am using a mysql database.
So I have two ASP.NET calendars, one for start date and the other for the end date. When you click on start date calendar, the start date appears on the STARTDATETEXTBOX. When you click on the end date calendar, the end date appears on the ENDDATETEXTBOX.Both the dates appear in MM/DD/YY format.
I have a button, called GenerateReport, which generates a report. I also have a gridview. The gridview has a column,when_ordered, which is of the datatype DATETIME.
I would like to have a SQL query behind the button, which generates only those fields from the when_ordered table that are between the start date and the end date. Something like "SELECT * FROM tablename1 WHERE calendar1.SelectedDate < when_ordered && calendar2.selectedDate > when_ordered.
I put a dropdownlist in a template field with 4 choices with the values of each to a,b,c,d and when i run the update query i need it to pull from that selected row,and read the value selected in that field. I tried this:
@choice = SelectedRow.Cells[9].Text.ToString() but it didnt work
how can i extract data from a dropdownlist thats inside a template field and use in a update query?
I want to update multiple rows of gridview (only price field. for that i have added textbox) on click of update button which is outside of gridview.I have done following way
Up to this its working fine but when no textbox updated then no need to go in for loop so i am looking for confiramtion before updating rows please help me how to do that becausei am less aware with javascript. another problem is textbox value disappear when page index changed how i can retain that values.
When i try to update a row using the update functionality of Gridview it updates all the rows rather then updating that specific row which is in edit mode.
Im trying to update my DB(DataBase) by using SQL UPDATE query ,but its not updating in the dataBase i receive confirmation(in testLabel) that one row is affected(dataReader = query.ExecuteReader(); return numbers of rows affected)...
I have given a HTML editortext control on a page,which generates HTML (i have to store it in my DB,that page is only for Admin) ,on pressing Update button , im receving in my testLabel that one row is affected(which shows DB is updated succesfully) but when i check my DB its in old state,it is not updating...
Here is my Event handler of Update Button which have to make updates in DB:
I have a gridview that has a sqldatasource for it's data and it works well. I also have four dropdown lists that I need to have filter the data in the grid if they have a value selected. Here's my query:
[Code]....
What I need is if a user selects an Asset_Tag from a dropdown list the gridview should requery with the Asset_Tag as a parameter so only that record gets called up. Is there a way to do this in the selected indexchanged event? The same would hold true for the other DDLs. It seems like if I assigne the datasourse programmatically I lose the builtin sorting ability which isn't acceptible for this application.
I am trying to bind a GridView to a MDX query using VB.NET. The MDX query is valid, as I am able to run it and get the desired results using the Microsoft Analysis Services MDX Sample Application - but I just can't figure out how to go about connecting to it in the VB code for my aspx page and then binding it to a GridView. I have been searching for a while now and keep hitting dead ends, and to be honest, a lot of what I have found has been over my head.
how to run a simple MDX query from VB.NET and bind it to a GridView?
I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
I would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.
Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.
Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.
Below is my visual basic codes:
[Code]....
Below is my Stored Procedure code: [Code]....
I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.
I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
I have a query . I want to edit the grid view columns in which user click the edit button he will edit the column in the grid and after that i want to add update button so that when he clicks on updates button after editing the row. The row will be updated and the grid will show you the new update row.
Basically grid is about that when user enter values intothe grid, the values will show in to the grid upon click button.I added edit button it works fine but it will incomplete without update button method ...
- I have a Gridview , when i click button edit of each rows to update database in Gridview . So when in edit mode , i want to update database in Gridview by using a button outside of the gridview instead of using a button inside Gridview .
- Here is my code used for update database by a button inside Gridview :
[Code]....
- So how i can do with a button outside Gridview to update batabase? .
I know this is simple and have already googled it, I know we should use foreach loop on collection of gridviews and have our logic there but I am unable to get the row index , If any one could give me a working example ,
i want to add a column on to the end of the gridview that runs an sql query based on that ID i.e! select * from thistable where id = (0). so basicaly i want to bind a sql query as a column!! how would i do this?
I have not done this before so pardin this question that I am sure has been asked before. I have a user that asks me to run queries each month and copy & paste the data into a spreadsheet I want to set up the queries in a web page for him to choose, enter the data in the parameters and either show the data in a gridview then export or just export to the spreadsheet direclty to the file name and location of his choice. Using C# Links or code samples would great.
Is it possible to use dynamic query filters with a gridview using a stored procedure as a data source? What I'm thinking of is a search page where there are multiple controls to enter in a search string and a radio button for the AND/OR query filters between the various controls. If not, what would be the best way to allow a user to select an AND / OR with a group of different query controls?
Here is the page I have created thus far using a view and no AND/OR option. I but I can't get it to work with my SP, also listed below:
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
