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 have a GridView where I have a ItemTemplate and where I have set 5 rows to with a buttoncontrol on each row.What I am trying to do is in the _Click event of the button, detect which rowIndex this button was clicked on but are not sure what I am missing in this code ?
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.
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:
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.
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.
my gridview column coming from database dynamicly it may be 10 or it may be 20. i added a blank row in grid throughdata table . i want to write something in this row and change color.
I have searched all over the internet and there are just too many solutions that basically is not working for me right now unfortunately. i just want to display my gridview header and I dont want to add a blank row in any form.
I am trying to update the value of a cell in a gridview at the same as conducting a post back to the DB....
Currently I am not able to even find teh control to puchthe data back to the cell, do I need to update the DB first then let the query read the updated record?
[Code]....
How can I get the new birthdate back into the ("studentDOBLabel") on the template at the same time I update the DB?
I want to make a link in databound data which is stockQtt. How can I do that? and I want target is blank and the link page is AdjStock.aspx below is coding.
I have a requirement that i need to remove the columns from gridview which are blank but at remove funtion it gives me error so i make that columns visible false now its working fine but at the time of exporting data from gridview to excel it also export that visible= false columns in spredsheet and i don't want that blank or hidden column in my excel sheet
I have gridview where there is column charges. If charges value is $0.00, I need to display it as BLANK or NULL that is it should be empty. I tried few DataFormatStrings but no luck.
i hav a gridview ... now i need to add certain number of rows... say 5 rows .... which would b blank .. the rows consist of itemtemplate of textboxes.. here is the grid ...
[Code]....
now i am binding this gridview with certain data say :
[Code]....
now the problem is if the row contains 2 data originally ... then it alwz shows up with only two rows with binded data... but what i want is 2 (databinded rows ) + 5 (empty rows with textbox ) = 7 grid view rows .... now how to do it ... after i hav binded the textbox with data already....with some empty columns corresponding to the above code ?
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?
While uploading excelsheet to datatable and bind it to gridview it will check blank data in excel sheet and when it will bind to gridview,the row in which blank present that row will be in red background color and the other row will occur in normal back color.
