Forms Data Controls :: Get Value Of A Label Control Inside The DetailsView?

Sep 1, 2010

I have a databound label control (i.e. Label 3) inside an Item Template that's in a DetailsView control. I just need to get the value of those label and compare it to some string. I tried several ways (i.e. Find control, DetailsView.Row) but nothing seems to work. I don't know if I'm using the FindControl methos correctly or if I need to access the Row first and do the findcontrol method.

Forms Data Controls :: Pre-Select RadioButton Inside A DetailsView Control?

Jan 15, 2010

I am trying (unsuccessfully) to pre-select a radiobutton control (within a DetailsView control) based on a value found in a database.

There are only two values: "Yes" and "No". A field in the database has one of the values in it and I want the correct item selected when the record is displayed in Edit mode.

All my other record fields are displayed correctly--this is the only one giving me issues. I am using vb.

Forms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview

Oct 31, 2010

I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.

1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.

2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.

1. Link button (on click) in the gridview footer (works fine)

protected void LinkButton1_Click1(object sender, EventArgs e)
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";

2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType

DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";

Forms Data Controls :: Find Control Inside A View Of Multiview Using Javascript (document.getElementById)

Nov 19, 2010

i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.

On the HTML code is rendered only the first view or the view that is activated on page load.

Is there any way to find a control inside the view using javascript? or I am doing something wrong?

Forms Data Controls :: How To Disable Button Inside EditItemTemplate Inside DetailsView

Jan 20, 2011

I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)

What I want is to Disable the button, if my boolean is 1 (true).

First I tried to convert my boolean value to text:

onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'

But got an error:

CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>

So another trial I did was to CAST the data from the database to be the text that I want, like so:

SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....

And my code changed to:

onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'

But got this error:

System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
at ASP.manager_aspx.__DataBinding__control74(Object sender, EventArgs e) in c:Documents and SettingsAdminMy DocumentsVisual Studio 2010ProjectsWebManager.aspx:line 219
at System.Web.UI.Control.OnDataBinding(EventArgs e)
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBind()
at System.Web.UI.Control.DataBindChildren()

So I wonder, is it possible to change the "Enabled" property based on by boolean value?

Forms Data Controls :: Gridview And Detailsview - To Click Two Times On The Select Button To View The Detailsview?

Nov 17, 2010

Im trying to link the gridview to detailsview and I used this page as my inspiration:

But Im trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
