I was wondering if anyone can help me work out what the user has selected in this selection changed event?his is what I have so far:
protected void rblNavigation_SelectedIndexChanged(object sender, EventArgs e)
{
string url = (GetCurrentPageName()).ToString() + "?" + Request.ServerVariables["QUERY_STRING"];
[code]...
The problem is that rblNavigation.SelectedValue is not the value that the user has selected to trigger this event. How do I get the value the user has just selected?I'm using C# and this selection event is inside my MasterPage.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I have a Datagrid on ASP.NET web form which I have bound to a data source and set it to have 10 records per page. I also have a hyper link column on the Datagrid , such that a user can navigate to another page (details page) from the list. On the details page, they have "Cancle" button to return to the Datagrid pageI am looking for sample code snippet on the Server Side on how to specify the page index to set the Datagrid after data binding. The idea is to ensure the user navigates to the same page index they were on.

View 7 RepliesI display a GridView where ther user can choose a Datarow with the select action. I catch the selection with the "SelectedIndexChanged" event of the GridView.

My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").
The goal is a facebook style interface where one users post can be commented on by another by clicking on a "comment" link. I am finding this some what difficult.
First - although I think that I will have to use a nested repeater, the initial issue is how to ID a text box that is embedded in the repeater.
<asp:Repeater ID="rptmain" runat="server">
I had a gridview with checkboxes in all rows.If I check one check box in the row remaing checkboxes in that row should also be checked and If I uncheck one check box in the row remaing checkboxes in that row should also be unchecked . my problem is I am unable to identify on which row the action is done(menas on which row the checkbox is checked or unchecked).In the Checked change event i wrote the code but i cant identify which row is checked..
View 7 RepliesI have a repeater control bound to a dataset. Within that repeater I have several further controls one of which is a dropdownlist. I trap the OnSelectedIndexChanged event of that dropdownlist because I want to recalculate some figures presented on the same row within the repeater.
How do I reference other controls which are on the same row of the repeater as the dropdownlist ? Is there an index property or other mechanism whereby I can identify the "current" row?

View 2 RepliesI have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.
My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:
"Object reference not set to an instance of an object"
I'm just starting out in ASP coding and would like to know what I'm not doing right?

View 1 RepliesOn a page load, how do I check to see if data in a table has changed? And if any data has changed, populate Gridview1?
View 2 RepliesI am creating a WebApp and got stuck on the "Save" process. I am gathering data from a SQL DB and using a DataReader to populate the DataList. The DataList hold employee data and there are quite a few. What is the best way to save the data to the database?
I had originally thought that once a Supervisor has verified the employee data, just click the "Update" button and save to the DB but how would I determine which fields in the DataList have been changed? I only want the changes saved.
use a Dataset to populate the DataList then build a second Dataset with the same structure and compare the two. Then save the changes to the DB. I had read before on the 4GuysFromRolla website that using Datasets in a web app wasn't the greatest ...
I probably should not bother writing these posts at this time of day. I have a gridview control on a web form page. Within the gridview I have
<asp:BoundField DataField="phone" HeaderText="Phone Number" />
<asp:CheckBoxField DataField="displayFrontPage" HeaderText="Display on Front Page?" />
From the documenteationI see, it seems to me that the checkbox I have here should be bound to the data field BIT on SQL Server. The gridview displays a checkbox. Lovely. But when I click the grid's edit, check the checkbox and click the grid's update, the value is not saved/changed.I thought this was straightforward asp control.
does anyone know if the gridview can tell you if a cell's contents have changed (during an edit) in order to determine if an update should be made against the database?
View 5 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?
View 1 RepliesI have a Gridview with about 6 templated columns hooked up to SQL, with a Save button below the grid.
When save is clicked, I loop through each row, and write each row back out to SQL.
Can you recommend a good way for me to tell whether the row has changed so I can avoid re-writing the row when nothing has changed?
This is not only for performance, but I also have a request to write out a "Last Modified Date" along with each record. So for that, I would need to know whether the row has changed.
I saw someone mentioned that the Gridview.RowState could be used for this, but I don't see how.
One alternative I see is to re-read each row from the database first, to see if anything changed. Another alternative might be to set a dirty-bit on each Textchanged, SelectedItemChanged, etc, for the row, but I'm not sure where to store that.
I wanted to create a dropdownlist that would trigger an asynchronous postback and update the Gridview inside the Updatepanel. However, no matter what I do, when the dropdownlist changes, nothing in the UpdatePanel will change, even the TestLabel....I've been banging my head against the walls for days on this -- why won't this work? When I remove the UpdatePanel code and triggers, all the code works, eg, you change the dropdownlist andthen gridview updates -- but it refreshes the page and this is why I wanted to put the Gridview inside an Updatepanel to make it look cleaner.[Code]....
View 9 RepliesI have created a web based form which has a drop down list (DDL) that lists various company names. I want to create a box in the form which displays the contact info for that particular company which is chosen in the DDL. Also, I want this info to be in a greyed area so that user cant modify (can just copy it).
what asp tool i should use for this (I am guessing textbox wont be good enough since user can modify the info that populates in it)
I have Gridview which allows user to edit record.I already build the event to save the new record, time and user machine information to a log database.However, this means a whole record is saved to the log... if the user just change one or two column/field out of say 20 fields, then there is a lot of waste. Also the change is not obvious.How can I log exactly which field(s) was changed in the record ?
