Forms Data Controls :: Using RadioButton Control Within Formview
Sep 28, 2010
I use a GridView control to select the row to display within the FormView. The FormView contains a RadioButtonList to facilitate the selection of one of its values. My C# codebehind contains a "selected_index changed event to grab the values from any of the modified FormView controls. My problem is that it is not picking up the selected radio button. Here's some code:
I have a FormView on my page and each ItemTemplate consists of 4 Radiobuttons. Now, let a user select a RadioButton, say r, on PageIndex, say p, and then moves to PageIndex k. When the user comes back to Index p, he should see the button r selected. I'm not able to do that. I have been able to save the radio button that was checked, but when the user goes back to the index, none of the buttons are checked. I've tried a lot of things like setting the button during PageIndexChanged, PageIndexChanging and PageLoad, but none worked.
I have been searching the net for quite a while and can't find an example of how to put a radiobutton or radiolist inside a formview. I have an objectdatasource that goes back to a table. One field in the table is Hydro -- which is an int field. There are three valid choices:
value Text 0 None 1 15 Amp Service 2 30 Amp Service
When I set my Formview to the objectdatasource my Hyrdo binding looks like this:
[Code]....
How would I change the above so that it would replace the TextBox with either a radiolist or 3 radiobuttons (I am ok with whichever is easier) so that it would look like this
Hydro: o None o 15 Amp o 30 Amp
Also, in the case of the update mode that the correct item is selected based on the value of 0, 1, 2 being read from the datatable
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)
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.
I need to use a RadioButton within a FormView, moreover must have access to OldValue and NewValue, but when I use the RadioButton returns "" as in both OldValue NewValue.
I am using a form view control which has two binded textbox. Now at this level it works fine and the textboxes show the values from database. But when i insert a panel inside the form view and move these two textboxes inside the panel, they dont show any values. What could be the reason for this?
I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
[Code]....
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.
I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.
I have a dropdown in the InsertItemTemplate of a FormView that I need to add code to it's SelectedIndexChanged property, however I can't seem to find any way to do this.
For example, if the dropdown was not in the FormView I would simply use...
[Code]....
...but because it's inside the FormView I can't use the above.
Couple quick questions:What's the difference between FormView1_ItemUpdating and FormView1_OnUpdating? Do they occur at different times in the update process?Still can't get my code to upload the file...what am I missing?
Instead of usng FormView with SQLDataSource control, I like to use it with LINQ-to-SQL. For example, can I write my own LINQ to SQL for Edit and Update? Will FormView control work in this way?
I've been searching on this question for hours and not finding a solutionI simply want to access a FileUpload control in the EditItemTemplate of a FormView.When the FileUpload control is outside of the FormView, I can access it like this:
[Code]....
Visual Studio says:"The name 'UploadImage1' does not exist in the current context" It says this about any controls I've put in the FormView.How do I access these controls in my c# code behind?
I have a textbox in Formview inserttemplate and I want it be invisible on click of a button.In Visual Studio the intelligensense for this textbox does not show up at all - meaning it is not accessible. However, the control eg textbox OUTSIDE the Formview is accessible.How to modify the code so that we can modify property of a textbox WITHIN inserttemplate WITHIN the formview ?
How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.
I am doing a library application. I am using a formview control to display and edit the details of an existing borrower.
What I wish to do is to allow the user to enter the borrower barcode into a textbox and select the details of the borrower corresponding to the barcode.
At present I have kept the textbox and a button outside the formview. Once the user enters the barcode in the texbox and clicks the button, the data is displayed in the formview control.
Now, my doubt is that is there a way to keep the textbox inside the formview control itself and use the value(Which should be user input) for selecting the details?
I want to add some functionality into a formview when it is in its "editable" state. I want to have a check box and if a user clicks the checkbox then it makes certain text areas and labels appear inside a table. Seems straightforward except that I am not sure how to access a formview in a code behind and do it when its in the editable state and then I have the consideration of the ProfileDataSource which shouldn't matter because thats not part of manipulating the visual elements inside the Formview.
I am trying to validate data using the OnItemUpdating event on a FormView control. The event is fired when I click the update button but
e.OldValues["txtDate2"].ToString() in the function returns a null value. What am I doing wrong here ? ValidateForm(Object sender, FormViewUpdateEventArgs e) { string val = e.OldValues["txtDate2"].ToString(); }
I have a Formview ('formview1') with a pager. I also have a gridview ('gridview1') linked to a SQL datasource ('History'). I need to set the SelectParameter ('Serial') of the datasource to be the value of a field on the current page in the formview. The value i need to get is in the ItemTemplate and is a label called 'SerialNumberLabel'. So, something like:
<SelectParameters> <asp:ControlParameter Text = "Eval fromview1.currentpage.itemtemplate.SerialNumberLabel" >
I also need to ensure that the SQL source and gridview rebind when the pager is activated.
