I have a large ASP.NET page with many TextBoxes and Validators The problem is that when I click on a button, I want to fire the validation for certain TextBoxes (but not all of them). And when I click on another button, I want to fire all of the validators.

I have on site three textbox controls, RequiredFieldValidator with each textbox and button (without any code). I have problem, when I set autopostback property of textbox controls to true. Regardless, that EnableClientScript sets to true or false, validation error dissapears - or show only few seconds. Helps only set CausesValidation property of textbox to true. And my question - if autopostback is set to true, should I set causesvalidation to true too to make proper validation process? Why it doesn't work?

View 1 RepliesI have a button on an ASP.NET page, and that button is (and needs to be) created via Javascript. The problem is, there are some validators on the page, and pressing the button is causing them to fire, and I don't want that to happen in this particular case. I am not sure what CausesValidation=false actually does on the page, but I was hoping to re-create it somehow.
I have been trying to locate the button by using a FindControl() statement in code-behind, but that doesn't seem to be working. If it did, I could just set the CausesValidation there...
I have build a composite control containing a Label, TextBox and a ImageButton. The idea:
Label text | textbox | imagebutton used for triggering an event
This textbox has a build-in validation.
When the imagebutton is set, i will use this imagebutton as a trigger. This imagebutton has an onclick event. Nou my problem is the following:
When i have my textbox on a form an click a button to validate my textbox validation takes place correctly.
If my textbox has the imagebutton enabled and i click this imagebutton validation takes place.
In my composite control i have implicity set imagebutton.CausesValidation = false;
I have a regularexpression validator which validates a valid email. I have two buttons on my form.

View 3 RepliesI have a aspx page with two linkbuttons and a usercontrol. One is used to save and one to cancel.
But even though I add CausesValidation="false" on the cancel linkbutton it still validate the the validationcontrols in the user control.
But if I add a dummy linkbutton inside the user control that has CausesValidation="false" it works and postback without validating.
Why can't I have the link buttons outside the user control?
I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?
I am working on Crystal Reports 8.5 and SQL Server 2000 as backend. I have a stored procedure which has been added to the Crystal Report. So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports. I have done verify database, removed and again attached the SP but the problem is not solved.

I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?

View 4 RepliesI have seen it on here or while googling, but never had a need for it with any projects, now i have a form that has 32 fields, PLUS up to 32 other possible fields.. Not sure how to go about this.. i dont think that having a form with 64 fields is the best solution as you may just need the first 32, but here is my attempt to explain it. I have a page which will gather configuration information, one of the things about this configuration is that you have a 1 to many relation with cameras.
So you have your set configuration for a location, but that location can have up to 32 possible cameras associated with it. But of course you may have just have one camara, so of course you would only need to add 1 new field. Any links to adding dynamic fields would be great.. the other thing is if fields are added dynamically, how to handle that in the insertign of the data into the database, since we wont know how many fields there will be until they hit the submit button.

View 1 RepliesI'm getting a List back from a WCF service and I want to set it to be the datasource for a grid. When I databind I get the error that "Deviceheader" is not a property of someObject.
<td><%# Eval("Deviceheader.DeviceID") %></td>
That is true, it's not a property, it's a public field
public class someObject(){
public DeviceHeaderDc Deviceheader;
}
How can I databind to these fields since they are not implemented as properties? Any suggestions? I'd like to avoid writing wrapper objects with property implementations if at all possible.

I have three textboxes to lookup three different product codes from a product lookup table.
When you enter search criteria in a Textbox it would popup listbox control with Products and
when user selects the product it populates product-id back in to textbox.
I have lookup table and listbox working. However, My problem is I can't figure out how to pupulate TextBox2 if search Criteria was typed into TextBox2and to populate TextBox 3 if the search criteria was typed into textbox 3 etc.
I have a problem with passing a model to a controllerIn my controller I have a HttpPost function that gets a EF model.The problem is that the form does not contains all properties of the EF model.When the function is called that gets this EF model, I get error messge of fields that are not nullable in the EF model.That's because the fields are not in the form, so the not nullable properties gets no value.
