Forms Data Controls :: Add Blank Row To Gridview When A Value Changes?


I'm sure this has been posted somewhere else but my first couple of attempts to find a simple solution have been unsuccessful. I have a GridView that displays data sorted by a particular value. Ther will be x number of records for each one of these values, sort of like this:

value 1 data data data
value 1data data data
value 1 .......... ......
value 2..... ....... .......
value 2 .... .......... ....
value 3..... ......... ....
etc, etc

Between each one of the "value x" sets, I'd like to draw a blank, empty row as a separator.

Forms Data Controls :: What Is The Value Of A Blank Cell In A Gridview
I am trying to check if a cell in a gridview's selected row is blank. Nothing seems to be working. See the different options I've tried below. When I check an empty cell's text.length is tells me 6 ?!? Is that a tab and a space?

[Code]....

Or should I say what is the value of a blank cell in a gridview?

Forms Data Controls :: Adding A Blank Row In Gridview?
Very new to C# although I have alot ofolder coding experience. Not much object orientated programming though. Anyways, Ihave a .net program I'm working on,basically to work on my skills although it will prove to be useful. I am keeping track of my work schedule. Currently, I am populating a datagridviewfrom a sql 2008 express db. My columns are: date worked, hours, paid, and paidon. What I want to do is add an empty row whenever the date corresponds to a date that is "Monday". My goal is to line break every week. So that each work week (Mon-Sun) is seperated by a blank row. I would rather not actually have this blank row in the database. I would like the gridview to do this on the fly. Here is my gridview code in my default.aspx file:

Forms Data Controls :: Add New Blank Row To GridView Within RowDataBound Event?
I am having trouble trying to do this within the RowDataBound event.

If I the following...

int Index = e.Row.RowIndex;
DataRow NewDataRow = MyDataRow.DataView.Table.NewRow();
MyDataRow.DataView.Table.Rows.InsertAt(NewDataRow, Index);

...it inserts a row but the columns are all filled out with the exact same data of the related row that the event is triggered on.

How can I get a blank row so that I can edit the colspan etc?

Forms Data Controls :: Display Blank In Place Of 0 In Gridview?
I have a gridview populatedwith some data.

There arefollowing columns:

Reason, Remark1 &Remark2.

As per database designer's logic if there is no data in above field then he replace empty to 0 and in my gridveiw 0 is displaying whereever the cell is empty.

Now I just want to replace 0 to empty.

One more thing that if it displays 0 in a hyperlinkFieldthen it should not be displayed.

Forms Data Controls :: GridView Goes Blank When Click To Next Page?
I have a single page with multiple gridviews.

[Code]....

The data binding is done manually in the code behind, which means you have to manually write the onpageindexchanging in there too. Normally that's done like so:

[Code]....

When you click to the next page on such a page, it is only blank if you have if(!Page.IsPostBack){} around your manual data binding. Well on this page with multiple gridviews I don't have that. But it's still blank when you click to the next page.

Forms Data Controls :: Gridview Sort Coming Back Blank
I've got the following code to handle filling a gridview. They need to enter a user ID in a field and click an OK button. This works and data is shown. However, if they decide to sort the data by clicking on a column header, the gridview is blanked out (there are no data in it) and nothing is seen on the screen again. Then if they click the OK button a 2nd time, then the data shows up in sorted order. They houldn't have to click the OK button to sort by a column. Below is my code snippet. Why does the gridview come back blank when I click on a column to sort? I have the following properties set on GridView111:

Forms Data Controls :: Using A Session Field As A Query Parameter - Blank GridView?
I have a seeminly simple task and am not getting the results I expect. I am fairly new to this, and am hoping for a shove in the right direction.I have set up a simple login control that works as expected. I am using the LoginView to replace the login control with a simple "Welcome Back <username>! Click this link"When I click the link, it takes me to the page I expect, and I can see the LoginName control I placed at the top of the page for testing.This page also contains a SqlDataSource and a Gridview that is based on that source. When I set up the data source, I clicked the Where button, selected "RegionRep" as the Column, "Session" as the Source, and have tried "Username", "username", and "User"... all with the same result, a blank page with nothing but the LoginName control showing.

C# - MVC - Blank Model Not Returning Blank Data
I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.

[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}

So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.

Forms Data Controls :: Create A Lookup Data Source Based On A Union Query With The Actual Data And A Blank Record?
I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.

The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of itemsI had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.

When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

Forms Data Controls :: The ControlToValidate Property Of 'RegularExpressionValidator1' Cannot Be Blank

Here is the error:

"The ControlToValidate property of 'RegularExpressionValidator1' cannot be blank. "

I don't know what the field name is when I generate a Gridview at runtime. It made sense that my code would work, but I am obviously misunderstanding how this works.

Forms Data Controls :: How To Produce Blank DataTextField In RadioButtonList
how I can have no text displayed next to the data in a RadioButtonList? When I do not set the .DataTextField attribute, it automatically puts a number in there (i.e. O 1 O 2 O 3). If I try to set the .DataTextField blank or to an empty string variable, it does the same thing. I have even tried to set the .DataTextFormatString attribute to a SPAN tag with the visibilty set to hidden which works but it spreads the RadioButtons far apart (i.e. O O O ).

Forms Data Controls :: How To Handle Blank Fields In DetailsView Update
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.

I get a message like this if I change the "State" field to blank when doing an update

The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.

Forms Data Controls :: How To Produce A Blank Record In A Dropdownbox Control
I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.

I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.

Forms Data Controls :: Nested Grids Goes Blank When Page Index Is Changed?
Ihave 3nested gridsas Parent/Child/GrandChild and Ihave assigned SqlDataSources to all the grids at declaration time.I place the SqlDataSource next to each grid as follows.

<GridView>..</GridView><SqlDataSource>..</SqlDataSource>

Because of this I am not doing anything in RowDataBound(...) event. But I used the RowCreated(..)event of Parent and Child grids to access session (Please look at the select statements of Child/GrandChild grids).

Parent grid'sRowCreated(..) event puts the value in the session which is used by Child grid. Child grid's RowCreated(..) eventputs the value in the session which is used by Grand Child grid.

GrandChildgrid has paging enabled and whenever I click on page index, Child and GrandChildgridsgoes blank. Parent gird doesn't go blank because its select statement doesn't take any"select parameters".

how to overcome this problem. I am attaching .aspx and .aspx.cs files

Forms Data Controls :: How To Validate A Text Box (if It Is Blank) Inside A List View Row, On Selected Index ?
i have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).

i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.

1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)

but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.

markup of code for listview is [Code]....

code behind for the ddl selected index changed is [Code]....

method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.

i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)

Web Forms :: GridView - How To Fill The Blank Rows With Alternate Color
I am having a gridview with alternative color i have used AlternatingRowsDefaultCellStyle. however, if my grid is not fullyfilled, ie the grid view page size is 20 and i have only 10 records in that page then the alternate row color will not apply for blank rows. My question is, How can I fill the blank rows with alternate color as well.

Hope there is some solution without adding empty rows at the end of the datasoure which will create problems while sorting the grids.

How To GridView Textbox Always Return Blank Value
