How can I implement the following:I would like to have a checkbox on the top of my gridview. When checkbox is checked should show all the hidden rows from the gridview but when is unchecked should only show the unhide ones.
I only need 1 checkbox at the top(not in the header of the gridview), I found couple of examples but all of the have checbox as coulumn and then added to the header as well.
I would like to filter Gridview1 with, control checkbox, and code as "If GridView1 rows of column FirstName have value 'John' then show only this rows."I have somehow with network help write this code. But code is not working as it should, and also I do not know how to add controls also for other rows with values such as 'James', 'Paul'...
For Each x As GridViewRow In Me.GridView1.Rows
If Not x.Cells(0).Value = "John" Then
x.Visible = False

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections.

[Asp.net / Vb.Net] How can I validate my gridview footer checkbox using Javascript. I have a gridview with footer having 8 checkboxes -(chkActive1,chkActive2,.....chkActive3) -
The condition I want to have is - The user need to check atleast 1 checkbox or else the transaction would not allow.
I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.
I am putting together a very simple GridView, one of the columns is a CheckBox.I would like the checkbox to update the SQL table as it is checked, the field in my database is a bit field.Currently i have the following:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("Purchased") %>' AutoPostBack="true" />
</ItemTemplate>
</asp:TemplateField>
This allows the Checkbox to be checked and unchecked however it does not update my SQL Database. I have tried a couple of things but can't seem to get this to work. I am assuming i'd need to write a custom bit of VB around the 'OnCheckedChanged', i do not want an edit button on the page!

Firstly i'm not asking for the exact code here but the below is what i'm trying to do:I have a gridview with DropDownList and CheckBox and I have a button outside the gridview that will add a new row within the gridview.I have no problems with the adding row but I have a problem with saving the state of the checkbox/drop down list.Everytime I checked the checkbox and add a new row, all the DDL/CB will be reset.So how can I do it so that when I add a new row, the checkbox that I've checked before will still remain check.

Next, when the checkbox is check and I hit the button "Transfer" the row in the grid in where the additional column checkbox has been check will be transfer to grid B and the remaining data will be move to Grid C?

View 1 Replies1) I have a checkbox field in a datagrid, and when you check the box, it highlights the entire current row, and when you check the next one, it stops highlighting the first one and highlights the one I just clicked on. What I would like to know is how can I keep all the rows with a checkbox highlighted?
2) I have a column in my datagrid that I have changed to combobox and I did two things both gives me this error, first I inserted the values for the combobox in the collection. Second, I connected to one of the tables with a binding source and has one of the columns as the options (advisors).
Each student has a different advisor so the field gets set to the correct advisor each time but the problem I am getting is when I scroll (doesn't happen for a little while) I get an error so i put in this sub to handle it and the error message box says: Error Happened Formatting, Display.
Private Sub DataGridView1_DataError(ByVal sender As Object, ByVal e As DataGridViewDataErrorEventArgs) Handles DataGridView1.DataError

I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.
Public Sub dataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles DGV_Categories.CellValueChanged
If DGV_Categories.Columns(e.ColumnIndex).Name = "Select" Then

I want to make a gridview with 4 columns. (Checkbox, Hyperlink name Title, Dynamic name Price, Dynamic named ASIN#)I want to be able to add new rows to the gridview from three different strings. I have a function that looks like this:Private Sub displayData(title As String, cost As String, asin As String)Is it possible to even add new data to the gridview with these strings.I've looked all around online and most things deal with databases. I'm also not 100% sure how to initialize at gridview.

View 1 RepliesI have a gridview that contains user info and one of the columns is a date when the user was added to the system. Is it possible to use the GridView.onRowCreated method to check if the user was added within a given time frame? If the user was added within that timeframe, then the row is added, if not, then that row is not added.
Note that I can't modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.
Is it possible to loop through a gridview with more than one page, the gridview I'm looking at has a pageSize of 20, there are say 26 records (over two pages) and I want to be able to loop though all the records.
For Each row As GridViewRow In GridView.Rows The count of the above is only 20 as the pageSize is set to 20, I can see that the pagecount is 2 but how do you loop through the next page in a gridview? Or would I have to just iterate through the orginal datasource?
How can I add check box to gridview and when checking select data items?
