Forms Data Controls :: Delete Blank Row In Table Bounded To Gridview?
Jan 19, 2010
GridView: grvResultPrimary Key: FLTIDTextBox: txtRemarksThere is a button named btnAdd in the FormView named FormView2.txtRemarks is outside the form.The scenario is that if user wants to add a record with empty textbox and click btnAdd then how to restrict user to add empty row to gridview?I have tried Validation by controling txtRemarks but it is not helpful for me because in the page there is a FormView1, FormView2 and grvResult.If I am applying validation then all other updation methods of FormView1 and grvResult are disturbing.Simple is that I want to give option to user that without empty data using txtRemarks, user can enter data to grvResult.

I have a gridview which is bounded with a Datatable. I have a button column in the gridview and on its click I am updating other row data and color. Data is been retained and color of the cell.
But when I am clicking other rows button, that particular rows color is retained but remaining color is again reverted to default. How can I rectify this.

I'd like to delete the row without using the DeleteCommand in GridView. I created the button "Obrisi" which should delete the row from the table, but when I click on it I get the following error: "The multi-part identifier "System.Web.UI.WebControls.DataControlFieldCell" could not be bound." and I don't understand what the problem is.
Here is the code (part of the code after else if is important):

I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

Very new to C# although I have alot of older coding experience. Not much object orientated programming though. Anyways, I have 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 datagridview from 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:

I have a gridview populated with some data.
There are following 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 hyperlink Field then it should not be displayed.

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.

I have three tables:
Colour(Colour ID, Colour)
DogColours(ColourID, Dog ID)
Dog(Dog ID, Breed)
Colour ID and Dog are primary keys.
I have three web forms, one for each table. Dog colours consists of data that is already in the system from the other two tables. It basically joins a breed to a colour. My problem is this:
When i try delete a dog which is being used in dog colours the program crashes. How can i prevent this crash?
The second problem, the data source in the dog colours web form has the insert, update and delete tick boxes greyed out in the 'configure the select statement' so i am unable to delete a colour and dog joined together. how can i delete something in the dog colours?
