Forms Data Controls :: Calculating Total Of Template Textbox Inside Gridview?
Oct 4, 2010
I have been asking this for a long time.But the answer what i get is not want i need.I have a gridview with two template text box (t1 and t2) inside gridview and four textboxes outside the gridview on the form (txt1,txt2,txt3,txt4).All these textboxes allow only integer value to be entered.What i need is to get the total of all these textboxes (ie,template textboxes as well as textboxes outside gridview) in a textbox named Total at the same time we enter values in a textbox.Also if i change the value of a textbox later that too should be reflected in the Total textbox .I know how to calculate the total of the textboxes outside the gridview.But i need the total of all textboxes including template as well as textboxes outside simultaneously
I want to calculate total inside a gridview and i want to display in footer row below is my code
But i am unable to get the quantity in the textbox when i enter a quantity it is showing null into the tetxbox and i have different prices for the items when ever i enter quantity for a price i am getting only the starting price of the item.Another problem is when i click button once the page is getting posted back when i click second time the event is getting fired i dont know why?
i have gridview and data is binded during page load ... below Name,Marks,percent are templatefields.. iam able to to calculate total in footer of Marks column.. but can any one tell me how to calculate the percentage depending upon total value for percentage column... iam calculating total in gridview_rowdatabound event
i have one grid which have 5 columns 1 for subject,2,3,4 for marks which have textbox to insert obtained marks,and last column have one lable to display total of (2+3+4),now i want total value on textbox event,when user enter any value to any column of textbox i need to display total of all three columns in total column.
I have a text box placed inside a gridview(template) . I need to update its value by a dropdown list event (Selected Item Changed event) placed in the same gridVew. But The problem is that , I need to update the text box of the same row the dropdown list (whose textChange Event haas been fired)
in my website there is a module in which i m fetching the data of present students in the gridview and i m entering there marks in the gridview textbox column (created by using item template)...I want to add required field validation to the textbox columns so that after clicking the submit button there should be an error message displayed if any of the textbox is empty...
in tat i was binding the table values like name,price and two textboxes for quantity and another one for total textbox for calulating total depends on quantity with price.
in my database table i have a row that contains minimum quantity=50 and maximum quantitiy=99 and price=0.66.and the min and max qty with price value varies.
i.e) if i enetring some quantites for example 51 during tat time it will fetch the between 50 to 99 price .ie)0.66 and caluclate the total value according to the quantity price i.e)51*0.66 and displayed in total textbox..
i dont want to use button to calculate the total value for each rows.
i entered the quantity at the same time the total will be calculated according to the quantity price.

I have a datagrid, with a template with a textbox in it. I am trying to add a "update" feature to my datagrid, writing my own code. Stuck on one thing though. I try to update the DataSet with this code:
But when running the code, an error message is showed saying that there where no changes to the GridView. This should probably be because the textbox in the gridview is never declared as a datasource for the gridview. How do i make the TextBox in the gridview template a datasource?
I am trying to add a Ajax AutoCompleteExtender to a Textbox (template) in a Gridview.In a different projects I have used a A.C.E with a Texbox on a form and it worksIn a different project I have used the gridview RowDatabound event to locate and added attributes that monitor keys stroke and the like (via java)BUT :(I am having a problem getting my head around how I connect the Ajax A.C.E to the Textbox in the gridview.My guess is, it is probably by adding an attribute to the textbox of the gridview but how do I reference / link the Ajax A.C.E.ORHave I just got in complete wrong?My aim is to add a combobox to a gridview ie a dropdownlist that the user can also type into.
I have Gridview that is populated from a data table, there are two additional template columns which are not bound (one checkbox and one textbox). I intend for the users to fill data in the unbound textbox and check the checkbox as needed. (there really is a good reason why the data is constructed in this way)
here is the problem, when the user enteres data into the textbox and hits enter, the gridview appears to postback, which wipes out the checkbox and the data in the textbox.
I tried setting the enable view state of the grid to false, that was supposed to stop postback but no luck. I have the enable view state of the textbox and checkbox set to true and autopostback set to false. but still no luck
so I need to either stop the postback or intercept the enter key in the text box and cancel the action, but that is a bit beyond me at this point
I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.
I have a webform developed in VB.NET and I am facing a strange problem. In the webform I have a GridView control which has two bound fields (Item # and Item name) coming from a master table and infront of these two fields I have placed a TEXTBOX control as TEMPLATE FIELD to take any value of particular item. But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there. Here is the ASPX code.
