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.
View 4 RepliesI have a gridview which makes use of a datasource. The columns are auto-generated.
Right now, my task is to make the first column into a url column. Does anybody know how to do it?
i am using asp.net 4.0
i want to remove Auto Genrated Columns of Gridview at Run Time and change the header text of these columns.

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.
View 2 RepliesI 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:-

in page load I am binding the grid view.
Even I have tried to hide that column doesn't make any difference for me.
is there anyway to set gridview autogenerated column width
View 2 RepliesI 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)

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?
View 2 RepliesGridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?
I have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.
How can I avoid this without explicitly adding HyperLink, or any other, columns?
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
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.
View 5 Repliesam 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.

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 have a gridview with columns (pseudo-code):
<COLUMNS>
AuthorFirstname
AuthorLastName
BookTitle
YearPublished
</COLUMNS>
what I would like to do is to only show the AuthorFirstName and AuthorLastName columns for the first row of each author. I am easily doing this with:
[Code]....
However the issue that I'm seeing now is the formatting what happens is that after the first row that the Author names are hidden but then the BookTitle and YearPublished become the new cell(0) and cell(1) respectively which means that book and year are displaying underneath the author names columns. so my goal is to do 2 things:
1 have BookTitle and YearPublished render under the correct headers and
2. For the second row and after I would like the cell to appear the same as the background, I dont want the user to be seeing what looks like an empty cell or textbox there.
I have a gridview that is being populated by an oracle DB. The gridview have 2 columns now one shows years and the other is a checkbox column. What is happening is my years column is very long and I wanted to know if I could split the column in half. I want say from 1970-1990 in the first column. The second column will have the checkboxes for the first. I want the third column to have 1991-present day and the fourth column to have the checkboxes for the third column. Can the grid view do this or is this something I have to do in oracle and have the gridview just display it?
ex.
1970 chk 1991 chk
1971 chk 1992 chk
1972 chk 1993 chk
1973 chk 1994 chk
I have a GridView with bound columns, for which I am manually setting the ItemWidth and HeaderWidth to 500px, and nothing happens. Is there some trick to getting this to work?
This is a column a large amount of text in it, and it keeps sizing to the width of the header text, which is simply "note". I don't want to set Wrap to false, becuase then the colummn could be thousands of px wide in cases.
i have a gridview which is populated from a stores proc using pivot tables. The column are created dynamically apart from a total column which is created as a template field. the gridview looks like below:

P4U
T-M
TSC
VIR
VOD

i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview
[Code]....
and here is my gridview:
[Code]....
i am also moving the total column in this code
[Code]....
and calculating my total in this code and adding my link to the total colum (which works fine)
[Code]....
now i just need to somehow add a link to the other cells and somehow get the value of the header text for that cell clicked.
I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

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.
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.

have a GridView with two columns: Part Number | Part Details
When I search for the part number 12345, the gridview will display like this
PartNumber | PartDetails
12345 | image1 (image1 will see as document picture)
If I search Part Number and doesn't get any data results in gridview the information will be:
PartNumber | PartDetails
0 | image2 (image2 will see as red cross picture)
How to change the image2 in the same column cell 1 in the GridView when the data results are "0" ?
