I have a question involving the ItemDataBound EventI have a linkbutton, btnOverview, that is displayed in a DataList ItemTemplate.I would like to select 1 of 2 imageurls for this button based on the value of haseOverview which is a field returned by the SelectCommend of the sqlDataSourcefor the DataList. I am not sure of how to reference this field.I have highlighted what I think is he relevant code section below.
I know how to catch a key pressed, but I don't know how to do that in a gridview to get the the row index and the value of the field. Explanation in the code below (it is going to be more clear I guess) :
[Code]....
In the txtPosition TextBox the user is entering a number and press the Enter key which launch the "HandleAttribute" event as if the client had click on the "imgbtnUp" ImageButton.
In my application, I am using DataList. In Item Template I added One GridView and SqlDataSource to populate data in GridView. DataList having one DataKey field, I want to pass this DataKey Value to the SqlDataSource as Parameter.
I build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id"; SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]); SqlDataSource1.SelectCommand = selectcmd; //The only problem is that I try to call the select method //but the compiler tell me I have to add a DataSourceSelectArguments SqlDataSource1.Select(); //I don't know what argument to add, so I put DataSourceSelectArguments.Empty // But it says variable "@id" must be decleared //I don't Know what's going on.
This grid looks great in the browser, but when printing, the date is duplicated - one w/ the correct format and one w/ the full datetime format (including hh:mm:ss). I've tried converting the datetime in the Select query, but keep running into error messages.
Interested in a way to call an event when the Required Field Validator component determines the assigned text field is not valid/empty. Is this possible? Somewhat surprised it doesn't have an event for this. Am I missing something?
With asp 2.0 and vwd 2005, I have a page with a radiobuttonlist, textbox and gridview with edit/delete. Using the radiobuttonlist, the user selects a search type and then enters the criteria in the text box. the click event of a submit button checks the rbl.selectedindex and chooses a sqldatasource.selectcommand with the where clause getting its criteria from the textbox. The gridview loads the data, but the edit/delete are not working. Code and relevant markup is below
I have a custom hierarchical data source based on the msdn example [URL] An event can be raised in the DataSourceView. If that occurs, I want to display a message on the web page.
The example is that I have a page with a TreeView control which uses a custom hierarchical datasource. If the user selects a node that they are not allowed to select, the underlying datasource will throw and error.
I want to capture this and add a message to the page. The Page_Error event is raised, but there are no eventargs.
Anybody know how to capture such an event?
An alternative approach, although not quite specific enough, is to set a flag during the datasource load event (indicating the datasource is loading) and test for this flag in the Page_Error routine.
I have a dropdownlist control in grid.On edit item of the grid I have to find the value of the dropdwolist and set it accordingly. tell the code.Its just one line code but I am not able to find the correct way.
I am using a GridView Control to display multiple fileds with 0's and 1's.
I am using template fields where CheckBoxes are used.
Where exactly and how do I apply the Logic to get a checked CheckBox when field Value=1 and unchecked CheckBox when field Value=2 .Also some times to be able to write a YES where fieldValue=1 or NO where filedValue=0
I have 2 fields in my gridview one called ScriptType the other BagNo, when a user click the edit button, I would like the BagNo filed to be disabled if the ScriptType field is = "TTA" and enabled otherwise. How can I do this?..something along these lines see below..I am using VB..
I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I have a grid view, and I add new column as a hyper link field, I want the navigationURL for this field to be Pageexample.aspx?ID=other field value like this
I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.
i have gridview with linkbutton.when i click linkbutton it should call javascript function which returns value would be input for database functions. how do i capture javascript function retun value(i am using Registerclientscriptblock)? and that should be input for database function. Inshort i need to call two function from link button click - one javascript function,one ado.net function which will update value in database. output of javascript function will be input for database function.
function Getlogitudelantitude(address) { return "35.3434343,-74.334343" } Linkbutton_click(object sender,Eventargs e) { register javascript function .. which should return value string s = "35.34343,-74.334343" then call database function(s) - does database operation } }
I have a details view control which contains a dropdown list.
I would like to update a row in the DV based on when the selected index change event occurs in another row of the
So far I know that 1) Place code in detailsview1.rowupdating event .
2) Make a row copy, not sure about the syntax here
Dim aRow As DetailsViewRow = Me.DetailsView1.Rows(DetailsView1.Rows.Item(?)) 3) Find my DDL Dim aDDL as dropdownlist = CType(aDDL.cells(?).Findcontrol("Dropdownlist3"0, dropdownlist) If aDLL.selected IndexChanged then Dim aTextbox as textbox = Ctype(detaislview.cells(?).findcontrol("Textbox6", textbox6) aTextbox.text = now()
I have a link button in my gridview. It is populating correctly; however, being I am populating the values in the gridview using "Eval()" method I don't know how to get the value of the selected Link Button (which is only selected by a user actually clicking the Link Button).
The user can click on the text directly (instead of showing the "Select" auto created). I want to be able to capture the item they have clicked on's Text property.
Example:Column 1
Value1 Value2 Value3
When the click on "Value2" I want the text property to be stored in a string variable (In this case the text would be "Value2"). In the past I have captured this through GridView.SelectedValue; however, I am not using autopopulate selected button so I need to do this manually and I am unsure as to how I will do this.
Here is my code for HTML and I have not created any code for C# (I want to capture the item using C# in my Grd_Tables_SelectedIndexChanged Event) [code]....
I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.
if (myDataList1.Count >= 1) { for (int i = 0; i < myDataList1.Count; i++) { //retrieving the exact i count from pageload ViewState.Add("newCount", i); //creating the dynamic grid with its corresponding gridview properties. grvDynamic = new GridView(); grvDynamic.ID = "GridView" + (i+3); grvDynamic.AutoGenerateColumns = false; grvDynamic.RowCreated += GridViewRowCreated; grvDynamic.RowDataBound += grvDynamic_RowDataBound; //adding bound field columns to retrieve data from stored proc BoundField metric = new BoundField(); metric.HeaderText = "Goal "; metric.DataField = "metric"; grvDynamic.Columns.Add(metric); BoundField mtd = new BoundField(); mtd.HeaderText = "MTD"; mtd.DataField = "value_MTD"; grvDynamic.Columns.Add(mtd); BoundField goal = new BoundField(); goal.HeaderText = "Tier Level Achieved"; goal.DataField = "value_goal"; goal.HeaderStyle.Width = Unit.Percentage(10); grvDynamic.Columns.Add(goal); BoundField you1 = new BoundField(); you1.HeaderText = "Month End"; you1.DataField = "firstLevel_you"; grvDynamic.Columns.Add(you1); BoundField you2 = new BoundField(); you2.HeaderText = "Month End"; you2.DataField = "secondLevel_you"; grvDynamic.Columns.Add(you2); ButtonField singleClick = new ButtonField(); singleClick.CommandName = "clickHyperlink"; singleClick.Visible = false; grvDynamic.Columns.Add(singleClick); BoundField metricId = new BoundField(); metricId.HeaderText = "Metric Id"; metricId.DataField = "metricID"; metricId.Visible = true; grvDynamic.Columns.Add(metricId); //binding the gridview to data. grvDynamic.DataSource = data; grvDynamic.DataBind(); grvDynamic.Columns[5].Visible = false; } }
protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e) { //this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&
md.value_MTD != null select md.metricID).ToList(); if (e.Row.RowType == DataControlRowType.DataRow) { // Get reference to button field in the gridview. LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];
This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
