The problem is when am assigning my session table value to newly created table and if now am changing any coloumn name then the session table value also changing.
But my question is am assigning Session value to newly created table so how should session value should be affected?

i have a situation, like this, there is a one data grid, which is empty, in that we can add the values, in that grid was paging enabled, so after the 10 record, remaining values ll be in the next page of the grid, so if i want to view that value, i should be use the paging option, here i m getting proble, becz, here i have use the code
" gvViewGoodsRecive.PageIndex = e.NewPageIndex;
gvViewGoodsRecive.DataBind(); "
but , this is not sutable for my method, becz here i m not getting value from data base, i just add the values without save in the database.
im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
In my web forms application I have a site.master page with an update panel (Java Script ToolKit). Inside the update panel I have a survey and a columns chart to show its results. The chart properties are
visible = false
ImageStorageMode = UseImageLocation
RenderType = ImageTag
When the user votes, his/her vote is stored in a sql server table The chart is rebound to its data source
The chart visibility is set to true and the survey's questions are hidden. I've been trying to set the columns for the maximum and minimum values to a different color using the code I found in "Samples Environment for Microsoft Chart Controls" [URL] under Working with Chart Data Data Manipulation Finding Data Points Find Maximum and Minimum Values:
[Code]....
I have not got the columns to change their color. I have put the code inside every event handler I could think of (after it failed to work inside the page load event handler): Inside the chart Init, load, and pre_render handlers. Inside the click event handler for the voting button (before and after I call the chart.DataBind() method). Inside the page pre_render handler. Inside the ToolKitScriptManager pre_render handler. I checked the code behind the environment samples. All, to no avail.
I am trying to change font color if the datafield has the string EMERGENCY.
This is my original template field:

Is there a limit of 1 for <%# %> code within a template field? I tried the IIF standalone and it worked but not when I put it within ForeColor '
I have a gridview which i have enabled paging. When i select a page in the footer, the page postbacks, and I lose all data.I am lost on how to enable paging and maintain the data in the table.I manually insertthe information into a datatable then bind because of the way i have to get the information.Here is what I have so far:

I sort a listbox items, using code below:
<script type="text/javascript">
function MoveDown() {
var selectedOption = $('#ListBox1 > option[selected]');
var nextOption = $('#ListBox1 > option[selected]').next("option");
if ($(nextOption).text() != "") {
$(selectedOption).remove();
$(nextOption).after($(selectedOption));
}
}
function MoveUp() {
var selectedOption = $('#ListBox1 > option[selected]');
var prevOption = $('#ListBox1 > option[selected]').prev("option");
if ($(prevOption).text() != "") {
$(selectedOption).remove();
$(prevOption).before($(selectedOption));
}
}
</script>
But when I submit a button and get listbox item in c#, I just get the order which not changed. How to get the changed data?
a designer interface (like visio)2. client to display the content created within the designer interface.We have the design outline in place, the client will be in many forms, via the web using Flash or Silverlight (depending what's installed) and via windows using a WPF application.I would like to know what people think regarding storing information from the designer, all the clients will need to access the information via the internet so a database storage solution seems the first choice. But another alternative is exporting the information from the designer in something such as XML and storing that as a physical file
View 7 RepliesI have a question, I have a gridview that shows a red balloon as imagebutton in one of the cells. Now i want to be able to let a users press the button, write a value in a record in the database and then change the red balloon to a yellow one. When the user wants (at any given time) wants the undo the value again the record should be rewriten again and the yellow ballon should be red again. Any tip is more than welcome :)
View 4 RepliesI have a grid view that I want to dynamically change based on data in my page. Specifically I want to change one of the title items and I want to hide a column based on a certain condition.
View 3 RepliesI have a DataGrid that is bound to a data set. Down column 1, I need each row in the column to be a link to another page or just plain text - which I can determine post-bind.
e.g.
<table>
<tr>
<td>Row 1</td>
</tr>
<tr>
<td><a href="page2.html>Row2</a></td>
</tr>
</table>
Can this be done in a DataGrid? I need to give the user an indication in the cell that there's a link versus no link to another page.
I have created a webpage using wizards to set up the objects, can I change the name of all the datasources by just going into the code and entering the new database (the tables are identical) ?ORDo I have to work my way back through all the wizards and re-enter parameters?
View 3 RepliesI have a gridview which shows the contents of the shopping cart. The qty cell is a template control bound to the qty field in the datasource. My ideal scenario is to have the user highlit the qty, write the new one and press 'enter' to update the sqldatasource but this may not be possible.
My second chose is an Update button to update the data but this erases the data from the other fields not listed as key.
I have tried the edit and update functions but then all fields are editable and I dont't want that, just the qty cell. If I change the read only atrribute to true on the ones that I don't want edited, then it erases the information from those fields.
I have a form which allows users to modify data, what's the best way to handle that so if two or more users try to make an update i get the data in there properly without overriding the new stuff. for example if name and bday are in the form, user1 changes name but not bday, same time user2 accesses the form, the original name and bday are there, user1 saves, but when user2 saves, since he had the original name value the original is saved over the first.

View 8 RepliesI am using entity framework. My model has entity tblGameInfo where in navigation properties are associations called tblPlayer1 and tblPlayer2 which links to entity tblPlayer. I have listview on my page where I want to show game info with players names. I have found that in of listview I should have e.g. one of those:

But it does not work. I got nothing displayed in a listview. I have tried many different options but cannot find working one. Probably is some simple mistake but I am new to asp.net and cannot find it. Second problem with this is editing. In edit template there is dropdownlist with all players.

How do I databind it? It is not allowed to bind and change properties? It writes me that element does not exist on a list of elements.
I have a datatable that looks as follows:
Make,Ford,0
Model,Fusion,0
Year,2010,0
Make,Ford,1
Model,Focus,1
Year,2010,1
I'd like to loop through each row and replace all the values of the same type in the 3rd column with a different value.
So for example I would change all the 0 to 1234 and all the 1 to 1235. So I'd end up with:
Make,Ford,1234
Model,Fusion,1234
Year,2010,1234
Make,Ford,1235
Model,Focus,1235
Year,2010,1235
Whats the best way to do that ?
I m having Gridview in Update Panel. If I select page 2, I want to update few contents in the same page. I m using Update panel for those contents.
<tr><td colspan="2" align="center">
<asp:UpdatePanel runat="server" ID="UpdatePanel3" UpdateMode="Conditional">
<Triggers><asp:AsyncPostBackTrigger ControlID="GridView1" EventName="---" /></Triggers>
<ContentTemplate>
<div style="border:1px solid #000; width:300px; height:35px;" runat="server" id="divSelectedRecords">
</div></ContentTemplate>
</asp:UpdatePanel></td>
</tr>
What event Name I have to give in Trigger?
I have certain columns in my DataSource such as "ID", "StartTime", "EndTime", etc.I would like to present them a bit differently in the listview.for example, I want to present the "StartTime" and the "EndTime" in ("hh:mm:ss") form, and would like to show only IDs smaller than 10.I thought about writing the code in
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
}
I have no problem writing the conditions in code behind, but the question is:since the ListView1_ItemDataBound event handler is fired for every column, how can I know in which one I am concerned, and so which condition to use?for example, if it is a "StartTime" then I want to have (DateTime)item.ToString("hh:mm:ss"), but if it is "ID", I only want to check if ID<5.
First off, sorry if this is in the wrong section. I have a gridview that loads from a SQL database. It has three columns, the first being a template column with a checkbox, the second being a name from the database, and the third being a field from the database related to that name. (the third column is empty). I want to be able to click on the check box in each row, and automatically have the third column populate with data that the user can select from a drop down list at the top of the screen or something. I am using VB, and I basically just need a way to make this checkbox, add a value from somewhere into the database. (Also, I know that I can just use Edit in the gridview to change data, but there will be a long list, and that way gets quite time consuming) I hope this makes sense, if not I can try rewording it.
View 5 RepliesI have created a FormView whose defaultmode = "insert". When loaded the FormView displays the InsertItemTemplate. At the top of the page is a DropDownList used to select Clients. I have added a list Item to the DropDownList with value = "0" and text= "Select Client" option. So the Page is in Insert Mode. SO FAR EVERYTHING IS AS EXPECTED.
When I select a Client from the DropDownList, the page remains in Insert Mode (Don't understand why? ) Could it be the default Mode setting? So I added the following vb code.
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
If ddlSelectClient.Text <> "(Select Client)" Then
If FormView1.CurrentMode = FormViewMode.Insert Then
FormView1.ChangeMode(FormViewMode.Edit)
End If
End If
End Sub
So after an existing Client is selected, the FormView Mode should be changed to EDIT. AND INDEED THE EDIT ITEM TEMPLATE IS DISPLAYED.
Ah but life is not so simple (after all this is a Microsoft Application). So I enter data in some fields and click the [Update] Button.
Then I get the following message:
FormView 'FormView1' must be in edit mode to update a record.
THe FormView displays the Edit Template, the Update and Cancel Buttons are displayed. All this should mean I am in edit mode.
Just call me FrankenSoft !@#$%^^& or is it MicroStein?
Oh by the way I'm using Linq to SQL data sourcess. Should I be? I'm having a lot of problems with the FormView using Linq.
Let me set this up:I have a master page. I have a regular aspx page - this page contains a Menu and a User Control.When I click on the Menu Item, it fires my click event. This will post back. The Master Page Uses Placeholder Controls where I dynamicaly create Label Controls with information and add them to the Placeholders. These contain data with tooltips. This works great. After the Master Page and Web Page load, it will then fire the Click Event from the Menu.The problem:The Click event will update data in the database, This data may effect the values that are created on the Master Page that are placed in the Placeholder controls. I can't seem to figure out how to change that data.
What I have tried:I have created a reference to my Master Page on my Web Page. In the Click Event after I have made changes to the Database, I call the function on the master page that Creates all the data and places them in the place holders. It Runs, but nothing changes on my page.Am I going about this wrong? Is there another way of doing this? I terrible work around, would be to just reload the whole page after I do an update.
EDIT: Purpose of this Website: Its called Utopiapimp.com. It is a third party utility for a game called utopia-game.com. The site currently has over 12k users to it an I run the site. The game is fully text based and will always remain that. Users copy and paste full pages of text from the game and paste the copied information into my site. I run a series of regular expressions against the pasted data and break it down. I then insert anywhere from 5 values to over 30 values into the DB based on that one paste. I then take those values and run queries against them to display the information back in a VERY simple and easy to understand way. The game is team based and each team has 25 users to it. So each team is a group and each row is ONE users information. The users can update all 25 rows or just one row at a time. I require storing things into cache because the site is very slow doing over 1,000 queries almost every minute.
So here is the deal. Imagine I have an excel EDIT(Excel is just an example of how to imagine it, I don't actually use excel) spreadsheet with 100 columns and 5000 rows. Each row has two unique identifiers. One for the row it self and one to group together 25 rows a piece. There are about 10 columns in the row that will almost never change and the other 90 columns will always be changing. We can say some will even change in a matter of seconds depending on how fast the row is updated. Rows can also be added and deleted from the group, but not from the database. The rows are taken from about 4 queries from the database to show the most recent and updated data from the database. So every time something in the database is updated, I would also like the row to be updated. If a row or a group has not been updated in 12 or so hours, it will be taken out of Cache. Once the user calls the group again via the DB queries. They will be placed into Cache.
The above is what I would like. That is the wish.In Reality, I still have all the rows, but the way I store them in Cache is currently broken. I store each row in a class and the class is stored in the Server Cache via a HUGE list. When I go to update/Delete/Insert items in the list or rows, most the time it works, but sometimes it throws errors because the cache has changed. I want to be able to lock down the cache like the database throws a lock on a row more or less. I have DateTime stamps to remove things after 12 hours, but this almost always breaks because other users are updating the same 25 rows in the group or just the cache has changed.This is an example of how I add items to Cache, this one shows I only pull the 10 or so columns that very rarely change. This example all removes rows not updated after 12 hours:
DateTime dt = DateTime.UtcNow;
if (HttpContext.Current.Cache["GetRows"] != null)
{
