Forms Data Controls :: Creating A Webform With One Gridview And Three Dropdownlist Which Are Outside The Gridview?
Aug 19, 2010
i'm creating a webform with one gridview and three dropdownlist which are outside the gridview.In edit mode of the gridview i want to insert the values form the dropdownlist.what i select in dropdownlist it should be in gridview...i've three columns. so i've created three dropdownlist which are outside..i dont want the dropdown list in the gridview it should be separete .
I have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole = new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi is the webform code behind partial class. CheckBox chk = new CheckBox(); chk.ID = _columnName; chk.DataBinding += new EventHandler(chk_DataBinding); //Attaches the data binding event. chk.AutoPostBack = true; chk.CheckedChanged += new EventHandler(ealmsapprole.Dyn_CheckChanged); container.Controls.Add(chk); chk.Enabled = true; This is the code for the event Handler internal void Dyn_CheckChanged(object sender, EventArgs e) { string err = ""; try { if (lblAppID.Text != "") }
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
I have a gridview that has the following colums Category, Weight , and an option to delete row. I user would like to be able to highlight two columns in excel Category, Weight and then past them from clipboard to gridview.
can i declare and define a datacolumn alltogether at runtime?? I need to add a column(this column is supposed to be displayed at last in gridview) containing a control(which control should i use? :P) which i would use for redirecting to a different page and it will display data related to that particular column in a gridview.
For eg: last column in gridview1 on page 1 will have text "details" after clicking it an event will be fired which will fetch details of that particular row from database. My major problem is to ctreate this last column with some event firing thing in it :-)
I created a database with ID, Title, Content, Date, ImgLnks, Image and Imagecaption and i'm using ObjectDataSource to populate the data. The field "ImgLnks" displays a new blank window with URL. This column is entered as text, inserted into the database and displays as clickable link in the gridview. My question is, is there a way that I can put an Alternative Standard Text in this column instead of displaying the clickable link like [URL] etc.? Text like, "Visit Page".
I want to create columns in gridview dynamically based on rows in a table and each gridview colum should have a checkbox. When I Click the save button, I want to save the checkbox state. How Can I do this ?
I am looking for a way in which to make a column in a GridView editable.
Currently i am looking into overriding the GridView so that the whole view is editable and then making all the column I do not want to be editable, read only.
I'm sure there is a better way, but I cant find it.
He has a drop down list and a textbox in the header of a GridView. I am able to do this if i create a new column and put the controls in the Header Template.
However I would like my column to span across the entire GridView.Columns.Count instead of having an unsightly single column.
I would like to create those checked/selected rows in gridview to SQL server database with a button click.For example, an user checks 2 rows in the gridview, and clicks on the create button. I would want the selected row/s to be created to the database. How would I go about doing this?
I have an accessdatasource with multiple columns, one column I use it to populate a dropdownlist. Can I use the data from other columns to insert into a table, insert being done in the aspx.vb page, without creating gridview etc.
Is it possible to make a detailsview one column visible= false and still be able to evaluate its contents?
I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable With TblBasket .Columns.Add("BskPrdCd", System.Type.GetType("System.String")) .Columns.Add("BskPrdDesc", System.Type.GetType("System.String")) .Columns.Add("BskQty", System.Type.GetType("System.Int16")) .LoadDataRow(Split("12345,Test product 1,1", ","), True) .LoadDataRow(Split("122,Test product 2,2", ","), True) .LoadDataRow(Split("123A,Test product 3,5", ","), True) .LoadDataRow(Split("44,Test product 4,1", ","), True) End With DstBasket.Tables.Add(TblBasket) With LfnGridView("GdvBasket") .DataSource = DstBasket .DataBind() End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.
I'm confident about being able to pass the query string, I just need help with getting the corresponding row's data ID from my database and making the gridview click-able, which will be the interaction which specifies which ID to be retrieved.
i have a gridview which is populated from a stores proc using pivot tables. The column are created dynamically apart from a total column which is created as a template field. the gridview looks like below:
CPW EE Foh H3G IND O2 ORG P4U T-M TSC VIR VOD Total
Stores Visited
70 0 0 12 0 16 18 7 11 1 2 8 145
i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview
[Code]....
and here is my gridview:
[Code]....
i am also moving the total column in this code
[Code]....
and calculating my total in this code and adding my link to the total colum (which works fine)
[Code]....
now i just need to somehow add a link to the other cells and somehow get the value of the header text for that cell clicked.
I recently got a form to work with the "HttpContext.Current.User.Identity.Name.ToString" String. That basic idea was I needed a hidden form field so that each record submitted would include the UserName of the user logged in to the membership. However, whenever I try to create a custom query for the gridview, it doesn't submit. how I would go about doing this? Code as below:
I am trying to update record in gridview using ObjectDataSource (with conflict detection)The following is the ObjectDataSource
[Code]....
Update Method is as follows
[Code]....
In ObjectDataSourceProducts_Updating(..) event , I am checking objects which are being sent to UpdateProduct(..) method. I found that both the objects " original_ProductDB and productDB " have the same the values. When I click "Update" in GridView after entering new value, ObjectDataSource is not picking new value
I have a stored procedure that creates a global temporary table. I fill in five records with nulls into the temp table. I select * from my global temp table. (I can replicate this in sql and see my table from the select * command) In ASP.net; I create a gridview that binds to the stored procedure as the select.command. I run my webform
The idea would be then to figure out how to edit the nulls and then append the data from my temp table on the actual table. I see nothing. No error. No grid. Nothing. Just plain white! What am I not doing right? Or what am I doing wrong?
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.
I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.
//Dynamically creating the Grid protected void btnAnalyze_Click(object sender, EventArgs e)
I have a form that will allow users to edit records. One of the fields is just a Y or N selection. I would like to use a dropdownlist to accomplish this. I'm fairly cetain this can be done but I can't find an example anywhere.I can bind the dropdownlist to Y or N but hwo do I set it to the value that is already in the database for the record that will be edited?
