Forms Data Controls :: Binding Both GridView And DetailsView To A Single ObjectDataSource?

Jan 15, 2010

I'm trying to bind both GridView and DetailsView to a single ObjectDataSource declaratively (in markup). I'm getting the error read as below when I tried to run it.

"The DataSourceID of 'DetailsView1' must be the ID of a control of type IDataSource. A control with ID 'ReservationsDataSource' could not be found."

It works when I bind GridView and DetailsView each seperately to my ObjectDataSource. Is it I can't bind two pagable data web controls to a single datasource?? or there is a trick needed to be done for this to work.

FYI, I'm trying to create a Master/DetailsView of my data. DetailsView of my application should show the record selected in GridView and it should be editable.

Forms Data Controls :: Binding ListView Controls To An ObjectDataSource Dynamicly For Updating?

Jan 28, 2010

I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...

<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?

Forms Data Controls :: GridView - Add An ObjectDataSource To The Mark Up - Binding Controls

Dec 16, 2010

I have a Gridview in the markup and I add an ObjectDataSource to the mark up which will be the gridviews data source. Is this a redundant way of binding controls? I believe using this method is good for small sites with little customisation etc. but, for large sites (multi lingual, hundreds of pages etc) I have been taught to create the controls in the mark up or code behind, then bind the controls on PreRender in the code behind. My new boss thinks this method is old school and the current way of using an objectdatasource in the mark up is the best way to do it.

Forms Data Controls :: Sorted Gridview Not Displaying All Rows?

May 18, 2010

I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.

I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.

If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.

Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.

Forms Data Controls :: Displaying A Datatable In Gridview, Having Trouble Lining Up The Rows

May 22, 2010

So I've been teaching myself ASP.NET and VB for about 3 weeks now, having trouble with datatables, not sure how to get the rows to line up like I think they should. My code:

Which gives me the data output I want, but the days are adding rows underneath the previous day instead of lining up side-by-side. The idea is that once it's working I'll replace the specific dates with calendar controls. The gridview currently outputs like this:

DataSource Controls :: Binding Multiple Rows Of Data From SQL To A Web Form?

Mar 23, 2010

Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.

The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.

The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?

Which is the best way to get data from sql and bind it to controls in this situation?

For example:

label1.text = sqlcolumn1.row1.value;

label2.text = sqlcolum1.row2.value;

Etc...

DataSource Controls :: ObjectDataSource Binding To Querystring When Don't Want It To?

Sep 23, 2010

I have an ODS control populating a Telerik grid. The ODS definition is pretty simple. It's set to call a method on a static class that has one parameter (entityID). I set this parameter in the OnSelecting event. When I test this, the world is a happy place and all is fine.

Then, I pass a query string to the page (which sets various unrelated values for the page, we'll say parameters X and Y). The page call's Telerik's radgrid.Rebind() event. When this happens, an error is throw from the ODS saying that the underlying method (the static data procedure) does not support parameters X and Y.

So, why is ODS thinking it should be using any querystring values at all when I have explicitly set the entityID parameter (of type Asp:Parameter)? How do I stop this from happening?

The Html:

[Code]....

The OnSelecting:

[Code]....

I see this odsList_OnSelecting being hit and the inspection of e.InputParameters only contains my expected single entry.

Stop ObjectDataSource From Data Binding When Validation Failed?

Feb 17, 2010

I have an ObjectDataSource that is bound to a GridView. The object accepts a parameter from a TextBox. The problem I have is when I use a CustomerValidator with a ServerValidate event, the ObjectDataSource would still attempt to perform a DataBind despite the fact the the customer validator has returned false. The following is the code in the ASPX page.

<asp:TextBox ID="sittingDate" runat="server" />
<asp:CustomValidator ID="DateValidator" runat="server" ControlToValidate="sittingDate" OnServerValidate="DateValidator_ServerValidate" />
<asp:ObjectDataSource ID="BatchDataSource" runat="server" OldValuesParameterFormatString="original_{0}"
SelectMethod="GetOrCreateSittingBatch" TypeName="BatchBLL" OnSelected="BatchDataSource_Selected" OnSelecting="BatchDataSource_Selecting">
<SelectParameters>
<asp:ControlParameter ControlID="sittingDate" Name="batchDate" PropertyName="Text"
Type="DateTime" />
</SelectParameters>
</asp:ObjectDataSource>
<asp:GridView ID="BatchGridView" runat="server" DataSourceID="BatchDataSource">

In the Custom Validator I have

protected void DateValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
/Ensure that the entered data is a date.
string input = args.Value;
DateTime result;
args.IsValid = DateTime.TryParse(input.TrimEnd(), out result);
}

How do I stop the ObjectDataSource from data binding when validation has failed?

Dec 10, 2010

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.

In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.

How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

C# - How To Stop ObjectDataSource From Binding Twice

Sep 30, 2010

This has been covered a couple of times, without a suitable answer:[URL]

I have created a custom paging data class that is used with an ObjectDataSource. In intial tests, I found it was performing worse than my old SqlDataSource code. Whilst investigating, I found that for every page load, the ObjectDataSource is being created and binding twice.

Investigating the links above led me to believe this could be a bug (or unexplained behavior) in regards to changing my GridView's column visibility in the OnDataBound event like so:

protected void gvContacts_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Pager && e.Row.Cells[0].Text != gvContacts.EmptyDataText)
{
e.Row.Cells[0].Visible = false;
if (Convert.ToInt16(lstSearchType.SelectedValue) == ADDRESS)
{
gvContacts.Columns[2].ItemStyle.Width = Unit.Percentage(30);
gvContacts.Columns[3].Visible = true;
gvContacts.Columns[3].ItemStyle.Width = Unit.Percentage(20);
}
else
{
gvContacts.Columns[2].ItemStyle.Width = Unit.Percentage(50);
gvContacts.Columns[3].Visible = false;
}
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["ID"] = "contact_" + e.Row.Cells[0].Text;
e.Row.Attributes["onclick"] = "javascript:selectRow($(this).attr('id').replace('contact_',''),2);";
e.Row.Attributes["ondblclick"] = "javascript:openContact($(this).attr('id').replace('contact_',''),''); selectRow($(this).attr('id').replace('contact_',''),2);";
//E-mail link
if (e.Row.Cells[4].Text != " ")
{
e.Row.Cells[4].Text = "<a href="mailto:" + e.Row.Cells[4].Text + "">" + e.Row.Cells[4].Text + "</a>";
}
//Birthday highlight
if (e.Row.Cells[6].Text != " ")
{
DateTime dt = Convert.ToDateTime(e.Row.Cells[6].Text);
DateTime now = DateTime.Now;
if (dt.Day == now.Day && dt.Month == now.Month)
{
e.Row.Cells[6].BackColor = System.Drawing.Color.FromArgb(255, 230, 160);
}
}
}
}

I use this event to customize the display of certain fields, as well as hide columns that are not pplicable during some search types. When I disable the event, the ODS stops binding twice. I can't really think of a way to get around this behavior. Has anyone else see this issue or developed a work around?

C# - How To Cancel Binding ObjectDataSource

Mar 24, 2010

CheckPara is my OnDataBinding procedure SqlDataSource1 is ObjectDataSource (it's only confusing name)

Language is Nemerle, but if you know C# you can read it easy
protected virtual CheckPara(_ : object, _ : System.EventArgs) : void
{
foreach(x is Parameter in SqlDataSource1.SelectParameters)
when(x.DefaultValue=="") //Cancel binding
}

so how can I cancel binding when there is not fully configurated ObjectDataSource ? Or... how can I run binding only when I done with all parameters ?

DataSource Controls :: Binding An ObjectDataSource To A Property In Aspx Code, Not Code-behind

Dec 3, 2010

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:

[Code]....

I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....

This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?

Databinding - ObjectDataSource Binding With ASP.NET Gridview Auto Adding Parameters?

Feb 16, 2010

I have a gridview databound to an objectdatasource. Everything worked great until I changed 2 columns from asp:BoundField to asp:TemplateField. These are the UPC column and the Part column. I wanted to show a link button for each of these fields that take the user to another page. Now asp.net expects these two fields to be parameters on the update store procedure. Why is this? How do I get it to not assume these columns need to be passed to the store procedure?

Here is the code for the grid view:
