using gridview to show data from table. on the aspx page i want to hide/show image depending on the value of one of the fields of a table. for e.g. say is_new=1 then show else hide where is_new is table field.
for this on aspx page i have one img element whose initial visible property is set to false. Now at runtime i want to show/hide image depending on value in each record. So what coding needs to be done and where?
I am using an ADO Entity Model for my ms-sql database.
My database has a Resellers table which has ResellerID (primary key, int) and Name columns along with other data.
I also have an Orders table which contains OrderID (primary key, int), OrderDate, ResellerID (foreign key to Resellers.ReselerID).
If I just do a query like:
[Code]....
I am able to reference order.Reseller.Name just fine with no problems.
However I have an EntityDataSource on my page as follows:
[Code]....
Notice the Include="Reseller" attribute in the datasource... I also have a GridView tied to that datasource as follows: I cut some of it off for breavity:
[Code]....
Now what I have listed above will run with no errors, but what I want to do is replace the column that displays "ResellerID" with the equivilant to order.Reseller.Name. In other words I want my grid to display the reseller's name rather than the numeric ID.
I have tried to change the DataField to "Reseller.Name" but that will generate the following error:
A field or property with the name 'Reseller.Name' was not found on the selected data source.
Is there anyway to do this without me writing a custom select statement in my code behind?
I want to show the textbox which is in Gridview, eventhough the Datasource[Table] of the Gridview is empty.The user has to enter some value and save it in the table. My problem, when there is no value in the table, textbox is not shown. I am using Linq, So the Gridview has to bind using Linq list or table The objective of the task:
1. Show the blank textbox when there is no data in the table.
2.A Addnew Buton has to show, If the user clicks the Addnew button, One more textbox has to shown and user can enter the second input.
i want show ten record from table in the gridview at 2 column in five row.
like this:
------------gridview-------------
record1 | record2
record3 | record4
record5 | record6
record7 | record8
record9 | record10
1 2 3 ...
-----------------------
look at this code :

View 1 RepliesI am building a little app to upload a picture and various downloads for different file types for the photos, but I also need be able to select the catergory they will go into. So I have two tables one that stores the catergory names and one that holds the paths to the photos and downloads the tables are related through the catergoryID.
What I need is those catergories to show up in the photo's and downloads table so that when I go to upload the photos I will be able to select the categories.

I have a table in my database called "Profiles". This holds data on Female and Male personal characteristics.On my aspx, I have a formview in edit mode which is binded to an object data source with a GetDataByUserId Select methodwhich retrieves data from the "Profiles" Table via a DAL.The "Profiles" table has some columns which relates to females only and some just males and some are generic to both.See example below
UserId - / of Type GUID
GenreId / of Type BOOL.
Hip Size (For females)
Dress Size ( For Females)
ChestSize (For Men )
TrouserSize (For Men)
Weight ( For both )
When the User logs in , they go to an update Page which has the Formview in Edit Item Mode and contains drop down Lists whichare binded to the Users Selected Value. The DDL are in turn bound to their related table such as HIP, Dress, Chest, Trouser etc.bjectiveIf a female user logs in I just want to show them the (Hip Size) DDL and DressSizeDDL in the Edit item template of the formview and not the ChestSize DDL or TrouserSize DDL.At present the GetProfileByUserId returns all colums from the tableMy question is how do I do this and just show DDL which are relevant to the Female or Male Only. In some cases the usermay not have selected an item in the previous form so they could also be NULL.Am i on the right path by writing a Select Query that checks to see if the User is Male or Female by checking the Genre column in Profiles first.Do I also need 2 panels, 1 to hide Female DDLS and the other to Hide MaleDDLs subject to logged in user genre.
Currently I have something like this, but when I click "update" the record doesn't get updated (but no error is returned).

now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) {
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(document).ready(function () {
$('.search_textbox').each(function (i) {
[Code] .....
Here's my code structure for gridview :
<asp:UpdatePanel ID="ConstructionActPhaseUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:gridview ID="PhasesTempGrid" ClientIDMode="Static" OnDataBound="PhasesTempGrid_OnDataBound" allowpaging="True" OnPageIndexChanging="PhasesTempGrid_OnPageIndexChanging"

and the way i bind the data to gridview is from textboxes ....

View 5 RepliesWhat I want to do is to replace number with a name. So if in the Month Column it receives five "1" it changes those 5 "1" to JANUARY.
Is it possible? This is because unfortunately I can only arrange my months by number and not by their name, this because of my queries and tables format, so, I thought maybe I can tell the gridview to change the month number to their relative month name.

View 4 RepliesI have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):
[Code]....
But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.
