Forms Data Controls :: Getting Data Out Of GridView Where Checkbox Template Field Is Selected?

Jun 10, 2010

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

[Code]....

My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:

[Code]....

Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.

Forms Data Controls :: Calculate SUM Of Gridview Column Where Template Field Checkbox Is Ticked On Button Click

Nov 9, 2010

I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.

There is a submit button on the page as well.(this is not in a template column in the gridview)

what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.

Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.

Forms Data Controls :: Changing A Checkbox To A Template Field Causing It To Pass A Null?

Jan 1, 2011

I've got a details view control on a page. One of the columns, from the database table, is a bit field. It is not nullable, and that's the way it has to be. Also, in most cases, when inserting data, it will be true (1) be default. I've found in testing, when inserting data, that it was false, for some reason. So, I changed the column to a template field and went to the InsertItemTemplate for that column, and changed the checkbox Checked property to True, instead of the default False. However, it has really screwed up the page because now it won't save anything at all! When I try saving something using the details view, it does show the checkbox as being checked, but man, once I try saving it I get an error message back from the database saying that the column doesn't allow for nulls.

Huh??? How in heck can the column on the page have a value (it is checked), but when it goes to save something it fails? Furthermore, before I converted this field to a template field, it worked perfectly. I tested several other insertions, and they all worked. But when I converted it to a template field, it stopped working? What's that about? I even tried setting the default value for the Checked property of the checkbox back to False, but that still doesn't work, it still wants to pass in a null. What's going on here? Why is it that converting a field to a template field, which was working perfectly fine before I made the convension, stop it from working at all?

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

Forms Data Controls :: Checkbox In GridView Isn't Getting The Checked Value Correctly?

Jan 18, 2011

I have problems with GridView control which has template field with checkbox in it. My primary concern is that same code works for all the other GridView controls I have in different webforms, but not in this one.

This code is supposed to get the identities (ID column in GridView) and then get the values of first two selected and finally redirect them to another webform as querystrings. I double checked the GridView and they are identical (except they are binded to different datasource).

Here is the code that doesn't work:

Forms Data Controls :: Checkbox Automatically Checked After Delete In GridView

Apr 23, 2010

I have a gridview control in which there is a column with checkbox. I will have to delete the rows of the grid selected by the checkbox. After the delete operation i am re-binding my grid we new datasource to populate latest data. The data is comig up correctly and the no of rows in the grid are also correct.

But the problem is that, if i select row 1 to delete and click on delete button, row 1 is deleted, grid is refreshed with new list, but row 2 checkbox is getting automatically checked. I don't know how this is happening. I have tried of writing code to uncheck all checkboxes after i rebind the grid. None of them are working. When i debug and see the items are actually showing as checked=false, but on the screen the check box is checked.

Forms Data Controls :: GridView Checkbox Not Retuning Checked Value Correctly

Sep 7, 2010

I have a GridView with a Template Field set to Checkbox. Issue is; when I click the asp:button I placed beneath the GridView to update the database, I do not get a checked value on the returned button. So it just skips my code and nothing happens.

[Code]....

Then I have my Method.

[Code]....

So when the code gets to this line if (cb != null && cb.Checked == true), the value is always False even for the checked box.

Forms Data Controls :: See If CheckBox In Populated GridView Is Checked And Compare To SQLDataReader?

I'm a little new in ASP.NET, so i don't know how the .NET machine fully works..I'm using two strategies to solve my problem, both invoked by a Button.Click event, but i don't know which one is better..My worries are about the server overload and page load time.This is the regular approuch i've used..

The second one is by using a funtion (named checkIfNumberExistsInDataTable) that does a binary search in a datatable to find a number
