I have a GridView A that have many columns, one of those contains price for each row. so the cue is how or in which way, can I update/refresh the total price that will be showed in a Label or TextBox (not in GridView Footer)?
My working platform is C# 3.0 / ASP.Net
Set up a "total" variable. Use jquery to iterate through each row of your table/gridview and add the particular column value to to the total. (The method would need to know to get the numeric value out of the Td or the text input.
On the onchange event of the textbox, call the method again.

I'm working with asp.net, and i have a gridview with some rows as textboxes. I want to know how to get the value of a textbox if those textboxes are created in runtime and the id are default values, therefore I can not access the FindControl method because I do not have the id of textboxes.
I'd like to show a listview in a C# application where every row represents a product so the property "view" is set on "detail". One column (the last one) should be a checkbox because it represents if the product is discountinued.
With the checkboxes property set to true, a checkbox appear in the first column so it doesn't work for my application.
How can add the checkbox to the last column? Thank you
The Checkboxes are always associated with the first Column. However you change re-order the display of the Columns.
All you need to do it go to the Columns designer and set the 1st colum's DisplayIndex to the last column's index.
Or do it in code:
listView1.Columns[0].DisplayIndex = listView1.Columns.Count - 1;
listView1.Invalidate();
Note the Invalidate which is necessary to enforce the display of the new layout..
I am using asp.net 4 and c#.
I have a gridview with a textbox that needs a unique value for the database. This value is to sort the data by precendence with in the database.
All my other validators work but they only check the value in the one box.
How do I validate that the integers are unique in that column.
The only thing I found to do this is "DataKeyNames" but that does not stop it from allowing repeating numbers.
Updating the order is done on button click.
Thanks for info.
You can use a customvalidator for validating this. In the CustomValidator's OnServerValidate function you can repeat through all the rows of the grid view, get the textbox and its value and perform the unique check.
For the Integer validation you can add a CompareValidator with Operator="DataTypeCheck" Type="Integer"
I suppose you could write a JavaScript method that will scan the contents of the grid onclientclick before submit.
I have jqgrid with 4 columns each with checkboxes format, I need to get All the checkboxes values selected and unselected values based on Column Names.Is it possible?
Updated : Grid Image
The demo from the answer shows how to add custom button in the column header of jqGrid. In the click event handler you can enumerate all rows of the grid and set the column contain to true or '1' depend on the way how you defined the column. In the way you can implement your requirements.
I'm building a wholesale order form on a website.
The current plan is to...
-get an ArrayList of DepartmentUnits
-a DepartmentUnit has various attributes like "deptId", "description" and its own ArrayList of StoreItems
-The StoreItems have attached ArrayList of various SizeOptions
-The SizeOptions have an inventory count integer along with their description
-Planning on putting an asp:Repeater on the page that has an asp:GridView in it
-Each DepartmentUnit will have its own GridView
-EachStore item will have a row in the GridView
-Each SizeOption will have a TextBox in the row (approximately 10 options)
-Each inventory count will be watermarked over the size option textbox
The question becomes how will I then collect all this information correctly once the form has been filled out? I don't like the idea of putting all this information in an update panel and then posting back each time a GridView row or worse one of the row's textboxes changes.
Any advice on putting a single save button on the page and looping through each Repeater item - and each GridViewRow - and each textbox - to get all the values entered?
Better to try collecting all the items added in a single table at the bottom of the page and updating the string with jquery each time a text box is modified?
Then just looping through the new table when saved? Not sure I know how to loop through that table though - updating if quantity is changed might be a bear too.
If it considerably simplifies the process I could just remove the Repeater aspect and put separate GridViews on separate pages.
Thanks!
I decided to have the item key be on the GridView statically and build the other columns dynamically. Then using foreach (GridViewRow gvr in gvMain) I can loop through each row and FindControl each textbox. After finding a textbox if the value has a quantity I add it to an ArrayList and keep going. Once done I'll loop through my ArrayList and adjust my shopping cart.
