Forms Data Controls :: Show The Textbox In The Gridview, When The Table Is Not Having Any Data?
Dec 2, 2010
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 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 have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :
[Code]....
[Code]....
[Code]....
[Code]....
I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?
So it works fine i can hover on gridview rows. Now I need to add OnClick event. When Row is clicked I need to pass value from SQL server table to textbox. How can I Add something like onrowclickevent? where I can use clicked row arguments?
function calc(row) { var grdID=document.getElementById('<%=grid1.ClientId%>'); var Rate; var excise; var Tax;
[Code] ....

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 have a customized gridvew i.e. grvResult. There is a textbox and a InsertButton in the footer.
If there is a data populated into gridview it is showing GridView footer and inserting data but if there is no data in gridview then its footer also not visible.
I have tried in two ways to make footer visible but it is showing following error:
Object reference not set to an instance of an object.
How to display empty GridView to insert new record if no data retreived for some record on the result from data table?Actually i am trying to give a user an option to add recrod from Gridview. On result of some query it is perfectly displaying data and a footer row with the insertion textbox but when there is no data in the gridview it is not displaying. It should display with footer having insert textbox.
I have a detailsview, and I was wondering how I can insert value from a textbox instead of a boundfield value. I am able assign value to textbox in code behind.
What 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.
I m Using DataList Controll for the time being. But i wana use DridView Controll that should display Data Horizontally. Is it Possible? if Yes then How?
I 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 have a textbox in a formview as well as a dropdown. When I select a value in the dropdown, the textbox should be made visible or invisible based on the value I select.
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.
If I write the following code, teh gridview will no longer show the data
gridview.DataSource = null; gridview.Databound.
My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.
