I have a GridView with a databound CheckBoxField (called Play).
This is the first displayed column in the GridView.
When iterating through the GridView Rows, how would I access the CheckBoxField's value?
I have created a gridview at runtime. See code snippet. My problem is when I hit edit on the gridview, and check the ManuallyResolved checkbox in the 2nd column, and hit update, it won't update. I'm not sure how to get the update to work with the dynamic checkboxfield. I just don't know what the code is and in what procedure to put it in.

Specified argument was out of the range of valid values.Parameter name: index
After adding a check box to gridview when i am updating teh gridview I get above error
cmd.Parameters.Add("@c_name", SqlDbType.VarChar).Value = ((TextBox)Gridview1Rows[0].Cells[1].Controls[0]).Text;
cmd.Parameters.Add("@c_amt", SqlDbType.VarChar).Value = ((TextBox)Gridview1Rows[0].Cells[2].Controls[0]).Text;
cmd.Parameters.Add("@c_type", SqlDbType.VarChar).Value = ((TextBox)Gridview1Rows[0].Cells[3].Controls[0]).Text;
cmd.Parameters.Add("@check", SqlDbType.Bit).Value = ((CheckBox)Gridview1Rows[0].Cells[4].Controls[0]).Checked;
Before to checkbox addition it was wroking fine
i want get value from checkbox column selected row of gridview
View 1 RepliesI trying to pass some values that the user selects but I am unable to set the CheckBoxField in my gridview.
Could someone please let me know how to do this?
Here is my code so far...
<asp:GridView ID="GridView1" SkinID="CompacGrid" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1" Width="400px" AllowPaging="True" BackColor="White"
BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3"
GridLines="Vertical">
<RowStyle BackColor="#EEEEEE" ForeColor="Black" />
<Columns>
<asp:CheckBoxField headertext="mm" />
I have a GridView with two CheckBoxField columns. They both have ReadOnly property set to false, but html code generated for them has attribute disabled="disabled". So the value cannot be changed.
Generated HTML example:
<span disabled="disabled"><input id="ctl00_ContentBody_GridView_ctl02_ctl01" type="checkbox" name="ctl00$ContentBody$GridView$ctl02$ctl01" checked="checked" disabled="disabled" /></span>
how to figure it out?

I have a search box on a web application that is to use a query I have built in Access to search through projects to find any that are related to the text entered in the search box.
The query in Access is just made up of parameters that use wildcards to search through all the fields. In Access the query works fine and returns the correct data but when I try and link this all up to a ListView in Visual Studio, the ListView just diplays the message "No data was returned"
Below is my page-behind code, hopefully you can see why it is not working but it looks like it should work to me.

I use ObjectDataSource and DetailsView for Updating records . my Bll input parameter method is an Object instead of regular parameter . So i though i could make my own ObjectParameter in ItemUpdating event of DetailsView and i need some modifiation on the data that user input on boudfield in detailsView . I don't know how to access BoundFiled data from ItemUpdating Method of DetailsView.
View 1 RepliesI can't seem to access a label that is outside the DataList. I wish to add the data in the label into a database, aswell as data that is inside the datalist (this is already working though). My SQL-query with only the specific label looks like this at the moment:
[Code]....
The data is added to the database when pressing a button inside the datalist (using onItemCommand). If I write UserIDLabel.Text the regular way it doesn't work either. The label is in the MasterPage, while the datalist is in a .aspx-page. If it is possible to somehow access the data that is in this label and add it to the database I would be ever grateful. Or is it somehow possible to add data that is in a Session and add it to the database?
I have two databases (DB1 & DB2) from which i wish to build a single table/gridview output, ideally i want to be able to sort the table by using any data.
However i cannot seem to figure out how to have more than one datasource per Gridview, and if i have more than one Gridviews then i can't sort all the data by any of the columns.
This is a oneway street, i do not want to update the databases from the webfront end.

I'm having a difficult challenge of passing a DropDownList Selected Value to a Data Layer having a Function containing 'cmd.Parameters.AddWithValue("@CourseDDLid", CoursesDDL.SelectedValue.ToString)'. Visual Studio is indicating I need to declare 'CoursesDDL'. I tried accessing the 'Find Control' method but it did not work. Below are the codes for your review.

I have to create some code for my website which will bring data from a database into my specific boxes. I have a map on my site which on click of a hotspot, a page will pop up showing a smaller map and the data underneath it. The data will be in text boxes. How do I get the data from the database into these text boxes?
View 3 RepliesLet me try to explain my situation. I have a database table which contains, among other things, a boolean column called PermissionSlipRequired. I have a repeater on my page, and before each row in the database is shown in the repeater, I want to use my code behind to check the value of PermissionSlipRequired. Based on whether the value of PermissionSlipRequired is true or false, I want to change the text of a literal within the repeater. That's a real mouthful; hopefully some markup and code will clarify. Here's my repeater:

For some reason I seem to be unable to update my DB through the datasource. Is there anything obvious as to why this wouldn't be working?
I even added static values to the update string to see if this works but it still has an issue.
I've googled around for a couple of days now and tried different solutions posted here and there, but nothing has worked so far. Therefore I'm forced to write a new thread about this subject.
I'm working on a solution containing nested listviews. The top listview lists different projects, and in each project a nested listview lists images from that specific project using a nested sqldatasource. Inside the nested listview I want the user to be able to add new images, and i'm using the InsertItemTemplate of the nested listview. When inserting a new image, the project need to be specified, as the project is a foreign key in my image database. The problem is that in my InsertItemTemplate, "Bind" and "Eval" does not work (I believe this is by design). Therefore, when adding the new image I don't have access to the project. I'm using the ItemInserting event of the nested listview to upload the image, and the optimal solution would be to have access to the project in this event and just pass it on as a parameter.

I have the program structure as below. How can I set some label values in the gridview row from dropdownlist in selected index changed event? how to write ddl_selectedindexchange?

Can not figure out what is wrong with this statement
I think it's very simple but i just don't see it at this point: I have a detailsview that's bound to a sqldatasource. I want to have access to the data in a field in the table thats not currenty bound/used in the detailsview. I have a table which has one collumn that contains a username of the user who submitted the record. This field is not bound in the detailsview.I want to have the detailsview show delete/edit buttons only if the current identity matches the value in this collumn of the currently bound record. But i don't want to show this field as a row in the detailsview. I thought maybe i can access this field in the databound event of the dview and create/show the buttons here. But how can a access this data if it's not used in a dview field? I also tried creating a templatefield for this field and set it to visible = false. But then i also can't access the data it seems.
View 2 RepliesI have a "simple" gridview that has some columns, and the ability for editing/deleting. I recently found that I can change the editing textbox to a dropdownlist and have follow that, using:
[Code]....
It's quite simple and instead of using an sqldatasource, I have successfully implemented using the sqlclient in the codebehind to bind data only when I want (since this GridView is for "reports" and is queried by many parameters from user inputs).From what I've found online, the only way people have populated the dropdownlist is by using an sqldatasource - is there any way to populate it using the codebehind sqlclient like I have for binding the gridview and other dropdowns on the page that are exactly the same actually. I'd obviously have to set the SelectedValue to be what the value is coming from the database, which I can't see being that difficult.
The tough part seems to be knowing when to access this "MoneyTypeEdit" dropdownlist. I thought it would be in the RowEditing event, so I tried something like:
[Code]....
And I know everything outside of the "inserted code" works, because it was fine before I added that, but the dropdown obviously didn't have any values. And I know the code inside the "inserted code" works because I use it somewhere else on my page to populate a similar dropdown. But I get the error that MoneyTypeEdit is null, and I'm guessing it's because it can't find the "MoneyTypeEdit" dropdownlist.

How does one access (programatically) the data in a field in a DetailsView? The DetailsView in question has just one record but 10 fields. I assumed (wrongly?) that the DetailsView has one row, representing the record, and 10 cells, representing the fields? How does one access the fields by name?
I've tried
MyText = Dataview.Rows(0).Cells(5).Text
but I'm told that cells(5) is outside range (the field I am trying to access is the fifth field).
