I want to add gridview dynamically with all formatting and with template fields ..
i m trying it by below way.
[code]....
but the problem is i m not able to assign datasource to gridview as i m not able to get object of gridview..
I need to format this date time into the format Day/Month/Year on the same template field.
I am avoiding doing this under SQL server because that will mean changing my data type in my dataset to string instead of data time which i do not want.
<asp:TemplateField HeaderText="Publish Date" SortExpression="PublishDate">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("PublishDate") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("PublishDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
I have seen a number of posts on this, but none that quite serve my needs. I have a GridView with template fields. I use postback because when a value is entered in one field a calculation is done to supply the value in another field. I simply loop through all the rows after each postback (there are not many so it is fast). I do not use a select command or button to select a row. After postback I do not know how to return the focus to the row that was being used. I can return the focus to the first row just by using gridview1.focus.
View 11 RepliesI have 3 edit template fields in the gridview with 1st and 3rd as a textbox and second one is a dropdownlist. The second one gets it's data from another table. I'm trying to get the values in the 2nd one and I'm unable to do it.

View 3 Replies I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

Iam using the below code in ASPX for displaying images that are present inside my website project folder
<a href=""><%# Eval("Columnname","Foldername/{0}") %></a>
eg:
<%# Eval("Gallery","ImageFolder/{0}") %>
Now my question is I want to call the foldername itself from database its column name is GalleryFolder
<%#Eval("GalleryFolder")%>
How to use eval inside another eval or is there any other options??
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesBackground: 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 have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.
I am facing certain problems with the data formatting in GridView when the data is bound dynamically to it.
I have a DateTime column and want to only show Date from it and not the time.
Another Decimal type column which accepts decimal upto 4 places, I want to show decimal upto the places defined in the particular value (don't know how to put it in the correct way, but here is an example of what I want).
i.e.
1.0000 should be displayed as 1 after the databound in the gridview.
Similarly,
2.3400 --> 2.34
1.0050 --> 1.005
1.1000 --> 1.1

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...
I am making one pointing web application. There are different Points like 20 Points, 50 Points, 75 Points,etc. These are saved in Database.This Points are belongs to some Vendors. Customer will take the Points from Vendors.want to show the summary in gridview like how many customer use 20 points, how many customer use 75 Points, etc.I want the Gridview Like below
Vendor Name 20 Points 50 Points 75 Points
ABC 5 7 8
XYZ 10 16 5
First Question, How can I represent the data in the above way?Second Question, If I add one more point like 100 Points, then how the one more column will come like below:
Vendor Name 20 Points 50 Points 75 Points 100 Points
ABC 5 7 8
4
XYZ 10 16 5

My datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

I am working on a simple table with 5 columns with a header and detail records. I need to format those detail records so that when I export to excel the formating stays with it.
I tried this as an example
=FormatDateTime(Fields!StartDate.Value, DateFormat.ShortDate)
It looks fine in report viewer howeverver when I export to excel it formats it as General.
I need to format Dates, Costs, and Text
I have a datatable with the following column names
ProviceID, ProvinceName, Year,
TPM, PM 10, PM 2.5, B(a)p
I'm trying to display data from this table in a gridview using template fields. Here's an example of a label in my item template
[Code]....
When i bind data to this grid view, i get an error saying column "PM 2" was not found. For some reason, the program is dropping the .5 from the column name. I am exploring the possibility of replacing the number with alphabets only but this may not be possible as the end user may not find it user friendly. Is there a way for me to get around this problem? I get a similar problem with B(a)p, it drops everything after the B. Any ideas on how to get the gridview to bind column names with special chars in it?
I am creating custom Gridview for dynamic Columns (getting columns from Database) and addting textboxes to headers for filtering data. I set the "EnableViewstate=False".

I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.

So am adding fields in the code behind and now want to add required field validators. Kicker, I think comes into play becasue all this is in a master page. So even though I may set the id of the textbox to say tb4, it's no longer tb4. So when I add the required field validator and tell it the control to validate is tb4, I get the yellow screen of death telling me thtat tb4 does not exist... cause it's the long huge master page ID. What do I do?

I want to disable few entries in the dropdownlist that's in the template field, depending on the value in BoundField when the gridview is being populated.
Below is my attempt:
[Code]....
JobStatus is the dropdownlist in the template field, and Status is the boundfield. In run time, the bolded line causes below exception: Object reference not set to an instance of an object. which I think is wingeing about null variable. Perhaps the templatefields are created after RowDataBound event?
I'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.

I'm creating dynamic controls based on a tree structure I built from a database.
Basically each part number in my tree, I want to be able to type in a serial number for, so the form will look something like this:
Part 1 [textbox] [save button]
Subpart of Part 1 [textbox] [save button]
Subpart of Part 1 [textbox] [save button]
Part 2 [textbox] [save button]
and so on. I have the generating of the controls correct right now. However, all of the controls just come out in one line like the following:
Part 1 [textbox] [save button] Subpart of Part 1 [textbox] [save button] Subpart of Part 1 [textbox] [save button] etc..
How do I go about putting a break in between each "row" I'm making so I can obtain the tree format I am looking for?
