C# - Enabling GridView Columns When GridView Checkbox Is Checked
Oct 14, 2010
in a GridView (ASP.NET/C#), I have a number of template fields - the 2 ones relevant to the question are 'checkbox1' and 'quantity'. The checkbox starts off as unticked for every row, and the quantity starts off as disabled for every row. But when the user ticks one of the rows checkboxes, I need a piece of JavaScript or something to check if the relevant rows checkbox is checked, and if so enable to the rows quantity textbox.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
I'm attempting to enable some checkboxes I have in my gridview when the user selects to "Edit" a row. I thought I could wire it up through the RowEditing event like below but it is not enabling the checkboxes as I'd hope it would. I would think that the pointer reference to the checkbox would allow me to edit the control's properties but doesn't seem to be doing the trick.
I have a gridview with one column of checkboxes and other columns with different custom controls. What I want is that when a checkbox is checked an event is triggered which toggles the visibility of other elements in the row .
I am trying to retrieve a value from the row based on the user checking the checkbox but the only way it works is opposite of what I think it should be. The problem is I can only get the values if I set "If RowCheckBox.Checked = False" So I have rows returned in the gridview:
row1, record1 row2, record2 row3, record3
I want to check row1 and row3 and grab the values record1 and record3 I use:
Dim str As String Dim row As GridViewRow Dim index As Integer = dgrdSearchResults.SelectedIndex lblStatus.Text = index For Each row In dgrdSearchResults.Rows If index = -1 Then index = 0 End If Dim RowCheckBox As CheckBox = CType(dgrdSearchResults.Rows(index).FindControl("chkResults"), CheckBox) If RowCheckBox.Checked Then str = dgrdSearchResults.Rows(index).Cells(2).Text lblStatus.text = str End If index += 1 Next
With this code I basically step out even when I have rows checked. zaybe I am looking to much but I cannot get it to return the values I need unless I change "If RowCheckBox.Checked " to If RowCheckBox.Checked = "False"
I have MyStudentList table having StudId,StudName,CourseId,Timing fields. There are number of entries here. I want to maintain their attendance.
I created a table StudentAttendance with fields StudId, AttendanceDateTime,AttendanceStatus(True/False) bit data type.
I fetched students list in GridView from MyStudentList table and want to display editable CheckBox. I just see student and able to tick it. The entry should be inserted in StudentAttendance table.
I can't seem to check the checked value of a dynamic checkbox within a gridview. I've tried dozens of ways to test the checkbox's checked value, but it still returns false, when it should return true. If I change the checked value to true in the ASPX web page, then it will return true, even when it should return false. Any ideas? I've tried many different ways of checking the checkbox value including the one below.
I need to make sure only one checkbox gets checked in a GridView. I have tried a solution on here, but I get an error. The other is looping through the checkboxes in the gridview to get the value, in this case, a date.
I a using Gridview bind to a dataset. For this example, I am only setting up two columns.
1. Edit button 2. A template field that will display "No" and in Edit mode will show a checkbox.
When I run this code... the page is displayed... I click on the edit button... the row changes to edit mode and I CLICK the checkbox (can see a it checked).Then click on "Update" Button... which takes me to GridView1_RowUpdating event. If I check the status of the "box"... it's checked status is ALWAYS false Why?
I want to count all checked checkboxes in gridview. How can I possiblty do that? I've tried several ways but didnt work. This is my code for checkboxes.
Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.
The problem I'm having is that when I try to read the value of the checkbox from the codebehind:
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).
I want to highlight the row when checkbox is checked in gridview with paging using javascript only. Without paging I am able to perform but with paging I am not able to solve this issue.
I am using Checkbox in Gridview item template once it checked it cant be unchecked..once i click the button the checked box should automatically unchecked.
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.
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.
i got checkbox in gridview which put inside the itemtemplate. the problem is when i tick on the checkbox, the value for checked property still is a false value. Wat;s wrong?
If GridViewRDR1_Hidden.Rows.Count > 0 Then For Each row As GridViewRow In GridViewRDR1_Hidden.Rows Dim cb As CheckBox = CType(row.FindControl("chkstatus"), CheckBox ) If cb.Checked Then MsgBox("True") End If Next End If
