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'm having trouble getting selected rows in asp.net. i tried to debug it and found out that the answer to "chkRow.Checked" is always false eventhough it is selected. I'm new to asp.net.here is my code.
Protected Sub btnApproveYes_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnApproveYes.Click Dim modID As String = String.Empty For Each row As GridViewRow In gvModule.Rows
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 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 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.
Then I have my Method.
So when the code gets to this line if (cb != null && cb.Checked == true), the value is always False even for the checked box.
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
i have code to update multiple rows in a gridview. What I want is that if the row value is = 1 in the database then the row is checked otherwise it's not. I've put some pseudo code in below to illustrate what I want to achieve.
I got a list of customers That I'm gone show in the gridview. I have added a checkbox infront of every customer so i can select what customers gone be used and passed to the next method. With a little bit of strugle I almost got everything working now except for this thing with keeping the values of checked customers when I page to the next page (2,3,4,5 ect).
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
conn.Open() Dim dr As SqlDataReader = cmd.ExecuteReader Dim da As New DataTable()
If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.
I have created a gridview and added a headertemplate field inside templatefield. Inside header template field I have added a button and a condirmbutton extender. confirmbutton extender uses modelpopup with ok cancel. This works fine but with one problem. I want this popup to open on button click only if user has checked atleast one checkbox from gridview. So far it shows this modelpopup everytime even user hasn't checked anything.
