Forms Data Controls :: Gridview Update By Button With A SQL Query?
Mar 1, 2011
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 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.
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 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 put this in a grid so that only one of the rows would have the txt box in it, it works ok ie the txtbox only shows up for the row with 1005 as the ID, but for some reason the query string for each row for the last element in the row, ie an AddToCart image button i have at the end of each row in the grid is not coming out right, ie the query string is missing when the page posts back for all but the last row of the grid which coincidently is the row with the 1005 ID, (the rendered code is shown way down, i apologize for the length of it ) here is the problem line. NOTE when i take the code out of the gridview on row data bound event then the page post back fine and the query string is there, but when i put the code back in the row databound event for the grid then the query string vars and values do not get posted back.
- 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 have a gridview with the edit update cancel.What i want to achieve is when i press update it will get the relevant data from the rowselected and then send an email.I have a rowupdated method which will send the email.But at what point would i get the data from the row when update is pressed? would i need to create another procedure for row updating or would i use selectedindexchanged?
I have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
[code]....
However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.
Ive got a list of records in a gridview (from an SQLDataSource) where a field value is set to True. I've also added a "reset" button in a template field at the start of the row in the Gridview.
What I would like to do is allow the user to click the reset button on a particular row and 'reset' the true value to 'false' (updating the source data).
I have a gridview with edit,update and delete options..Using a radiobutton,how it is possible to select a particular row of gridview and update or delete that particular row?
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
I have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
I have a gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.

i got a problem to update my database which i bounded to datagrid. The problem is, i want to update my database only by clicking one update button at the bottom.. when the user click it, all the fields will be updated to database.
Here I want to assign the above database work to my team members. When I check the above check box and press assign button ,it shows in another page means the gridview selected row shows in another grid in another page .
And once i check any check box and assign , automatically the checked row vanished from my grid view.
