Forms Data Controls :: Load Data From Mysql Into Checkbox = Checked?

Dec 18, 2010

I have 13 checkbox which is consist of outlet locations, The way i store into database is converting the 13 outlet code and store in string type which is need to split it when the need to view it.

My problem now is, i would like get any releated outlet code checked into checkbox which is the outlet code store into mysql in same column and row. for example:

Outlet code store into my cLocCode column inside table itemdetail. The data inside store in string type:

|cLocCode |productcode |
|200,201,202,203,204,205 |xxxxxxxxxxxxxxxxxx |

As all of u can see the cLocCode store as string. I would like to load it into web form as checkbox which is like this:

x Checkbox200.Checked x Checkbox201.Checked x Checkbox202.Checked x Checkbox203.Checked
x Checkbox204.Checked x Checkbox205.Checked x Checkbox 206.Unchecked

this is the situation.

Forms Data Controls :: Get Value Of Label When Checkbox Checked

Jul 22, 2010

I have a label and a checkbox that reside in a datagrid. When the checkbox is checked (OnCheckedChanged), I would like to send the Checkbox value and the label.text to a method. I don't have a way of retrieving the values. I've seen a lot about retrieving all of the values from a datagrid, (myDataGrid.Items), but am not sure how to get the value for a specific row in the datagrid.

Forms Data Controls :: Binding To Checkbox Checked When Using A Repeater

Dec 20, 2010

i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview

Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....

is this done with the itemdatabound event? and how is it done?

I have a formview in edit mode, with submit button and checkbox. I want to click the button and have it test to see if the checkbox is checked. The ID of the checkbox is "TestCheckBox".

Forms Data Controls :: Gridview With Checkbox.checked Always False

Jan 13, 2010

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?

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 :: Update MySQL Database Checkbox Value In Gridview

May 5, 2010

I have been stuck on this for a while and I can't seem to get it to work despite looking for answers in books and all over the web, so I hope perhaps you all can help me figure this out...

Here's what I'm trying to do....

I have some information in a simple product database displaying in a gridview table. One of the columns is a row of checkboxes indicating whether the item has been discontinued or not. When the row gets updated, it needs to update the checkbox value in the database.

1. It needs to be disabled until the row is getting edited.

2. Send the string value of 0 or 1 to the database when the row is updated.

Here's the code for the sql datasource and the gridview part in question...

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:sqlDataMaster %>"
ProviderName="<%$ ConnectionStrings:sqlDataMaster.ProviderName %>"

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 :: Cannot Assign Values To Checked Property Of Checkbox At Runtime

Apr 22, 2010

I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.

When page loads,I get error - Specified cast is invalid!

The code is as follows...

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>

Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.

Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.

I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.

I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.

Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.

how i can edit and update Checkbox.

where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
