Mar 17, 2011
I am using gridview. I Added checkboc under itemtemplate.My page works fine. i have set my page according 508 standards. It looks for associated control id for every textbox, check box..etc.
When i check my page by 508 standards its giving form lable is missing for gridview item tamplate checkbox. i tried adding lable inside item tamplate and i set the check box id as Associated control id for the label. eventhough its not going off that error. After setting some text my errors are resolved.

I 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?
I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
like this in a function in AddColumns button clickevent
gv.Columns.Clear() Dim chkCol As New TemplateField chkCol.ItemStyle.Width = 20 chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center gv.Columns.Add(chkCol)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim chkbox As New CheckBox chkbox.ID = "chkSelect" e.Row.Cells(0).Controls.Add(chkbox) End If End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click Dim linkId As String Dim summary As String = "" 'Enumerate the GridViewRows For index As Integer = 0 To Me.gv.Rows.Count - 1 'Programmatically access the CheckBox from the TemplateField Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox) If cb IsNot Nothing Then If cb.Checked Then linkId = Me.gv.DataKeys(index).Value End If End If Next Me.Page.Title = linkId End Sub
But here i am not getting Check box even i used find control. how i get checkbox
i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
I have a Formview residing inside am Item Template of a Gridview. The formview is not populating, and I am pretty convinced that I am not passing the parameter properly from the Gridview to the Formview. I have listed the relevant code only, so that you can scan though it easierGridview tag:
I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:
My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:
Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.
not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID CustomerID InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.
I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>
I have a webform developed in VB.NET and I am facing a strange problem. In the webform I have a GridView control which has two bound fields (Item # and Item name) coming from a master table and infront of these two fields I have placed a TEXTBOX control as TEMPLATE FIELD to take any value of particular item. But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there. Here is the ASPX code.
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
I have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....
I am using Visual Studio 2008 Professional Edition. I googled for the same, it says u might not have selected crystal reports feature while installation of vs. I am sure that i had selected installtion type = Full/Complete.
So has it anything to do with vs service pack etc. I dont have VS 2008 SP1, but VS 2008. Or wud be better if we can add crystal report component explicitly. (kinda standalone installer for crystal reports and then it will automatically merge with VS.)
i have a gridview which consists of databounds and dropdownlist control. When I press the Add Grid Row Button, it will insert a row. Now my question is, if the user selected an item in dropdownList in the firstrow and the user click the AddGridRowBtn Again which will generate the 2nd row, how would i maintain the selectedItem in the dropdownlist after postback?
