Data Controls :: Display Automatically (Auto) Generated Row Number In GridView Column
May 7, 2015
I would like to inquire about the delete the data in gridview with automatic number parameter ..when I edit a field with auto parameter number, how do I delete a field that does not automatically sort ..ex:
1. ROBERT
2. EMILIA
3. JOSE
When I remove the column to 2 EMILIA, then display in gridview 1. ROBERT 3. JOSE.
Coding that I got when I remove emilia then display in gridview 1.ROBERT 2.JOSE .. (sequence automatically)
private void Bindemptydt() {
//Declare a datatable for the gridview
DataTable dt = new DataTable();
//Add Columns to the datatable
dt.Columns.Add("COLUMN");
dt.Columns.Add("TEXT");
The above code exports gridview1 data to excel, but the requirement is export data with row no as first column in Excel. I tried to add row number in dataset that binding to gridview, when we sort data in gridview, row number are not in correct order.
I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.
To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.
My Designer Code is:-
[Code]....
in page load I am binding the grid view.
Even I have tried to hide that column doesn't make any difference for me.
I have a gridview which has a column of auto generated select buttons, where a user can select a row.However, I would like to add a column header to my auto generated select buttons in order to make the gridview look complete, but I am unable to see how I can do this. Does anyone know how I can add a header text to an auto generated select button?
I need to make a link for all the rows in one column of a gridview(VB .Net) where the grid has been auto-created from the data source. The link would simply point to another ASP details web page. The examples I have found have all been in C# and I don't quite follow them.
I have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview
I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.
Is there any way to disable autogenerated edit, delete buttons in gridview. As they don't have names to use find contro, how can I find the edit button in the row and disable it and enable when required.
am designing report using gridview in which i want drill down report, i.e. when i click a cell of gridview which contains value from the database. i want a new gridview to be populated with detailed report, which should be generated by passing some values from parent gridview.
i have written some code for the same,but in the code the event is not getting fired.
code is:
in gridview rowdatabound protected void gvHdr_RowDataBound(object sender, GridViewRowEventArgs e)
Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I'm new to CSS. I need to display a number (generated dynamically through ASP.NET MVC action method) on to a Square (normal image , whose face needs to be replaced with the dynamic number ).
I have project in asp.net with sql server backend.i want to auto generate a number for particular column.with the auto generated number i want to insert some other data in the same row same table. on button click event.details
railway PNR no.:- want to autogenerat passenger details:- want to inserted simultaneously
Currently, I am programming a web-based application with Visual Studio.NET 2003, and having a problem with an err below :
An error has occurred because a control with auto-generated id 'dgPreventiveMaintenanceSchedule:_ctl5:_ctl3' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events.
That err occurs while I am rendering my datagrid for certain data. In the other words, it occasionally happens.
I've been trying to debug one by one, but I still don't any clues for this kind of err.
